Description

The invention relates to a plug-in module for arrangement in a hybrid module of a motor vehicle, a hybrid module for a motor vehicle for coupling an internal combustion engine and a transmission with the plug-in module according to the invention and a drive train for a motor vehicle with an internal combustion engine and a hybrid module according to the invention. Furthermore, the invention relates to a method for assembling a drive train according to the invention.

Currently available hybrid modules that can combine electric motor operation with engine operation by coupling an internal combustion engine to a powertrain of a vehicle usually include an electric motor, a disconnect clutch, its actuation system, bearings and housing components that connect the three main components into a functional unit.

The electric motor allows electric driving, power gain for engine operation and recuperation. The separating clutch and its actuating system ensure the coupling or uncoupling of the internal combustion engine. If a hybrid module is combined with a dual clutch such that the hybrid module is located in the torque transmission direction between the engine and the transmission, the internal combustion engine, the hybrid module, the dual clutch with its actuation systems and the transmission must be arranged behind or next to one another in the vehicle.

Such a positioned hybrid module is also referred to as a P2 hybrid module. However, such an arrangement very often leads to considerable installation space problems that also influence or impede the assembly.

From the DE 10 2009 059 944 A1 For example, a hybrid module is known which has the disconnect clutch within a rotor of an electrical machine. Part clutches of a dual clutch device are axially offset next to the rotor of the electric machine and thus also arranged next to the separating clutch. The partial clutches are nested radially. The actuating systems for the individual clutches are arranged axially offset next to these clutches.

The DE 10 2007 008 946 A1 teaches a multiple clutch for a vehicle with a hybrid drive. In this hybrid module, two friction clutches are arranged within the space enclosed by the rotor of the electric machine. The available space in the hybrid module is largely determined by the electrical machine used and their laminated core.

On this basis, the present invention seeks to provide a plug-in module, a hybrid module and a drive train for a motor vehicle available, which combine a small space with the possibility of easy installation and compliance with low tolerances.

This object is achieved by the plug-in module according to claim 1, by the hybrid module according to the invention according to claim 6, by the drive train according to the invention according to claim 8 and by the inventive method for assembling the drive train according to claim 9. Advantageous embodiments of the plug-in module are specified in the subclaims 2 to 5. An advantageous embodiment of the hybrid module is specified in dependent claim 7. An advantageous embodiment of the method for assembling the drive train is specified in subclaim 10.

The features of the claims may be combined in any technically meaningful manner, for which purpose the explanations of the following description as well as features of the figures may be consulted which comprise additional embodiments of the invention. The directions axially and radially refer to the common axis of rotation of said aggregates. Thus, the axial direction is oriented orthogonal to friction surfaces of the slats.

The invention relates to a plug-in module for arrangement in a hybrid module of a motor vehicle, comprising a substantially rotationally symmetrical plate carrier and at least two coupling devices, in particular a separating clutch and at least one starting clutch, wherein the coupling devices each have at least one disc pack, each of at least one lamella torque-resistant with a Carrier device, in particular a toothing, the disc carrier is connected. The plate carrier has essentially the shape of a hollow ring cylinder composed of two rotationally symmetrically arranged hollow cylinders. It is envisaged that the entrainment means are arranged in the radially delimited by the disk carrier space on at least one of the radially spaced and facing sides of the hollow annular cylinder.

The plug-in module has on the disk packs of the coupling devices connected inner disk carrier and outer disk carrier on, with which a respective coupling device rotatably connected to at least one output side of a module to be equipped with the plug-in module hybrid module. A respective inner disk carrier or outer disk carrier has at least one axially extending through opening, so that a tool can be axially guided through the through openings of the inner disk carrier or outer disk carrier in order to exert a force with a radial component for the radial displacement of a radially projecting locking element, in particular a spring ring, in one mounted state of the plug-in module on the disk carrier radially adjacent rotor arm.

The inner disk carrier and outer disk carrier are each arranged radially opposite the common disk carrier.

It is provided in particular that in the mounted state of the plug-in module in or on the rotor carrier, the locking element extends radially from the rotor carrier into the plate carrier, in particular in its radially inner, first hollow cylinder 93.

The inner disk carrier or outer disk carrier are rotatably arranged about the common axis of rotation, so that they can be arranged axially aligned with each other in a certain angular position, so that in this angular position the tool can be passed through the through openings.

In addition to the function of the access openings and the tool inserted therein for radially displacing the locking element, the passage openings and the tool also serve to position the inner disk carrier or outer disk carrier and consequently the disks of the disk packs of the coupling devices arranged thereon in relation to each other exactly Mounting the coupling devices in the common plate carrier to facilitate by axial insertion of the coupling devices as a whole.

The coupling devices can be configured as wet clutches.

The disconnect device is in particular connected to an input side of the hybrid module. Preferably, in addition to the separating clutch, two partial coupling devices of a dual clutch device are provided, the disk sets of which are connected to an output side of the hybrid module.

The torque-resistant application of a blade of a disk set to a driving device can allow an axial displacement. For this purpose, the entrainment device is preferably designed as a spline. A hollow annular cylinder is a body whose inner hollow cylinder forms an outer side which is radially opposite the inner side of the outer hollow cylinder.

Thus, a plug-in module that can be tested outside of a hybrid module is made available as a subassembly or subassembly, which is also called a triple clutch when three coupling devices are received.

The advantage of this plug-in module lies in particular in the high dimensional accuracy or the low mounting tolerances in the mounted state due to the fact that almost all assembly steps and surveying operations that are necessary for the production of the plug-in module outside a rotor of an electric machine of a hybrid module, for which the plug-in module is provided, can be done so that in a reliable manner all geometric relationships of the coupling devices to each other and in relation to the plate carrier can be set to the respective desired actual measurement.

In addition, adjusting operations on the coupling devices can thereby be made simpler or more accurate. Furthermore, the plug-in module according to the invention makes it possible to manufacture this for different hybrid modules or rotor carriers, wherein only the contour of the plug-in module is to be manufactured to match the rotor carrier in order to provide a unit as a so-called "add-in" which is independent of location and time Rotor carrier can be integrated.

In particular, it is provided that Lammellenpakte of two coupling devices are arranged radially offset from one another and the entrainment means for connection to at least one blade of a disk set in the radially delimited by the disk carrier space on the two radially spaced and facing inner sides of the two hollow cylinders of the hollow annular cylinder , This means that the entrainment devices are arranged in a radially separated from the disk carrier hollow annular cylinder space at radially opposite inner sides, where the disk sets are rotatably connected, so that the disk sets are connected to opposite inner sides.

In a further preferred embodiment, a further coupling device is arranged axially next to one of the two coupling devices, of which also at least a lamella is arranged on a driver device on the inside of the hollow cylinder, on which also at least one lamella of the lamella packet of the axially adjacent coupling device is arranged.

This means that the disk set of the third coupling device has such a distance from the common axis of rotation of the coupling devices that the disk sets of the axially adjacent coupling devices overlap in the radial direction. The fins of both disk sets are rotatably connected on the same side of the same hollow cylinder with the local entrainment facilities.

Despite the arrangement of three disk packs, the plug-in module according to the invention has the advantage of easy handling during assembly, in particular on the assembly line, and when used in a rotor carrier of a hybrid module to be generated, so that the assembly and assembly can be done manually in a simplified manner and not susceptible to interference automated.

In particular, it is provided that the disk sets of a first part clutch device and a second part clutch device of a dual clutch device are arranged on the inside of the outer hollow cylinder and the disk set of a separating clutch are arranged on the outside of the inner hollow cylinder. On these pages of said hollow cylinder, the slats of the disk packs are connected to there realized driver devices.

Preferably, the entrainment devices are designed as toothings which have a plurality of teeth distributed on the respective circumference and having axially extending teeth. In this case, at least one support element can be integrated in this toothing, which serves to receive an axially applied to a coupling device actuating force for actuating the respective coupling device. Thus, e.g. such a support element to be a gap in the toothing, on which axially supports a counter-plate of a plate pack or can support.

To form a mechanical unit which simplifies the assembly operations, it is provided that the hollow annular cylinder of the disk carrier has at least one front-side connecting element which radially connects the two hollow cylinders of the hollow annular cylinder.

In order to transmit a torque from a rotationally driven component to the plate carrier or in the reverse direction, it is provided that the plate carrier has at least one torque transmission element on its radial outer side, for transmitting a torque from the plate carrier to a component radially connected thereto. In this way, a torque can be transmitted from the disk carrier to a rotor carrier of a hybrid module surrounding it radially, and in the opposite direction.

The torque transmission element may also be a toothing, which allows an axial insertion of the disk carrier or the entire plug-in module in a rotor carrier.

The disk carrier can be made in one or more parts, in particular in two parts, having an inner part and an outer part and a mechanical connection of the inner part and the outer part is carried out at a radial position between the radial positions of the inner hollow cylinder and the outer hollow cylinder. Thus, in particular a front-side connecting element may be divided into two, wherein an outer part of the front-side connecting element is arranged on the outer part of the disk carrier or is executed by this, and an inner part of the front-side connecting element is arranged on the inner part of the disk carrier or is executed by this, and a mechanical connection between the inner part of the front-side connecting element and the outer part of the front-side connecting element is executed. This mechanical connection can be implemented by a multiplicity of screwed or riveted connections realized on the circumference of the connection region or by clinching or welded connections. The multi-part design of the disk carrier makes it possible to produce the disk carrier with simpler or more cost-effective production methods. In addition, the multi-part design of the disk carrier opens up the possibility of a different mounting sequence of the disk carrier in a rotor carrier of a hybrid module, since initially one of the parts inner part and outer part can be arranged in or on the rotor carrier, possibly coupling devices in the space surrounding the rotor of the electric machine of the hybrid module can be used and only then the other part can be used, which was possibly previously equipped with a disc pack another coupling device.

In particular, a respective passage opening should be aligned substantially with the axial course of the inner, first hollow cylinder of the disk carrier. Preferably, the passage openings are arranged exactly at the diameter about the common axis of rotation, which also corresponds to the diameter of the inner, first hollow cylinder of the disk carrier. This allows the use of a structurally simple designed tool; namely, each angular position at which the Through openings are aligned with each other, a pin that can be inserted axially through the aligned through openings. In this case, the through-openings and the pin are designed such that it does not collide with the pin in the axially inserted state of the pin in the pass-through openings and when inserting the disk carrier in the rotor carrier to a collision of the pin arranged on an inner side of the disk carrier for non-rotatable recording of slats Lamella packages one of the coupling devices comes.

To facilitate the assembly is further provided that the hollow annular cylinder of the disk carrier has at least one front-side connecting element which connects the two hollow cylinder of the hollow annular cylinder radially to each other, wherein in the transition from a substantially axially extending hollow cylinder of the disk carrier of the plug-in module to the front-side connecting element of Disk carrier has a portion with at least partially oblique course in order to realize a wedge effect on the radially projecting locking element to move it radially upon axial displacement of the disk carrier in the rotor carrier.

Thus, the axial insertion of the disk carrier of the plug-in module is facilitated in the rotor carrier, as due to the radial displacement of the locking element, the locking element no longer axially blocks the sliding movement of the disk carrier. The region with an oblique course can be formed by a conical segment between the respective hollow cylinder and the front-side connecting element. In an alternative embodiment, the region with an oblique course is convexly curved on the outside, similar to a hollow spherical segment. This convexly curved region thus includes points at which applied tangents have the aforementioned oblique course.

For axial fixation between disk carrier and rotor carrier, it is preferably provided that the disk carrier has a form element on one of its radial boundary sides, to which the locking element, in particular the spring ring, arranged between rotor carrier and disk carrier can rest axially. This prevents axial relative movement between the rotor carrier and the plate carrier in one direction.

In a favorable constructive embodiment of this form element is formed by a recess into which the arranged between the rotor carrier and plate carrier locking element, in particular the spring ring can engage radially. The recess, which can also be referred to as a groove or recess, makes it possible for the locking element or the spring ring to be supported axially on one side on the recess and thus block the axial relative movement between the rotor carrier and the plate carrier. In particular, the engagement of the locking element takes place in the first hollow cylinder of the disk carrier, which forms the radial inner boundary.

Another aspect of the present invention is a hybrid module for a motor vehicle for coupling an internal combustion engine and a transmission, which comprises a plug-in module according to the invention and an electric machine whose rotor is rotatably connected to a rotor carrier. The rotor carrier is non-rotatably coupled to the plug-in module, so that torque applied by the rotor of the electric machine can be transmitted to the plug-in module. A radially protruding locking element, in particular a spring ring, is arranged in or on the rotor carrier and extends radially from this region into the plate carrier. As a result, an axial fixation of the disk carrier or of the plug-in module on the rotor carrier is ensured.

For actuation of axially juxtaposed coupling devices, an axially acting actuator, which is mechanically connected to a pressure plate of one of the two coupling devices, pass through the disk set of the axially adjacent coupling device to realize through this disk set through an axial motion transmission. The clutch assembly comprising this disk assembly is associated with an actuating system which can be located within or outside of the radially and axially enclosed by the disk carrier space. Correspondingly, an actuating system which is mechanically coupled to the actuating element which axially passes through the disk set can also be located inside or outside the space enclosed radially and axially by the disk carrier. The mentioned actuating systems can be assigned to the two partial coupling devices of a double clutch device.

The entrainment means, which are preferably provided as toothings, are arranged for transmitting the torque to the two axially juxtaposed coupling devices with equal radial distances to the common axis of rotation, but in one of the axially adjacent coupling devices the lamellae which do not interact with the carrier devices of the plate carrier have a smaller one Have radial extent than that of the adjacent coupling device, as between the radial end faces of these slats and the driver axially acting Actuator is passed through the disk pack.

An actuating system for the separating clutch can be arranged axially on the sides of the disk carrier opposite the two mentioned actuating systems, in which case an actuating element assigned to this actuating system passes axially through a front-side connecting element of the hollow annular cylinder of the disk carrier.

The rotor carrier is preferably configured in terms of its shape at least partially complementary to the outer shape of the disk carrier, so that the rotor carrier forms a recess in the form of a hollow cylinder, in which the plug-in module according to the invention can be inserted and is preferably positively connected to the rotor carrier, e.g. by means of an external toothing, which cooperates in a rotationally fixed manner with an internal toothing of the rotor carrier. This means that the rotor carrier radially surrounds the disk carrier at least in regions.

Due to the separately manufacturable plug-in module, a modular assembly of the hybrid module can take place.

The locking element, which is in particular a spring ring, can be arranged under radial prestress between the plate carrier and the rotor carrier. This ensures a secure radial engagement of the locking element in the plate carrier, so that an unintentional solution of this axial fixation is excluded.

Likewise, the present invention relates to a drive train for a motor vehicle with an internal combustion engine and a hybrid module according to the invention and with a transmission, wherein the hybrid module with the internal combustion engine and the transmission is mechanically connected or connected via coupling devices of the plug-in module in the hybrid module.

In addition, according to the invention, a method for assembling a drive train according to the invention is provided in which a plug-in module according to the invention is provided, a rotor carrier of a hybrid module to be produced is provided, an output shaft of an internal combustion engine is provided, the plate carrier of the plug-in module in the radially enclosed by the rotor carrier space is used, and a non-rotatable mechanical connection between the output shaft and one of the coupling means of the plug-in module and a non-rotatable mechanical connection between the plate carrier and the rotor carrier is realized. According to the invention, a locking element, in particular a spring ring, is brought radially into positive engagement with the rotor carrier and the plate carrier.

In this case, the steps of realizing a respective rotationally fixed connection are not necessarily to be carried out in the stated order.

Before realizing a non-rotatable mechanical connection between the output shaft and one of the coupling devices of the plug-in module, a housing part of the hybrid module to be provided with the plug-in module can be rotatably mounted on the output shaft.

An actuator or an actuating system for actuating one of the coupling devices, in particular a separating clutch, can be arranged in or on a wall of the housing part. The rotor carrier, on which the rotor of the electric machine is arranged rotationally fixed relative to the rotor carrier, can be arranged on a portion of the housing part, so that the rotor carrier is rotatable relative to the housing part.

During the assembly process, the plug-in module with a separating clutch received therein as well as a further coupling device, such as e.g. a starting clutch, inserted axially into the rotor carrier. An intermediate shaft coupled to the plug-in module or means, e.g. is coupled to an input side of the clutch, is rotatably coupled to the output shaft of the internal combustion engine.

In an advantageous embodiment of the method according to the invention for assembling the drive train, a tool is axially inserted through the axially extending through openings in the inner disk carrier or outer disk carrier in order to exert a force with a radial component for the radial displacement of the radially projecting locking element, in particular of the spring ring. The radial displacement of the locking element space is created in the radial direction for the axial insertion of the disk carrier or of the plug-in module in the rotor carrier. During the insertion process of the disk carrier in the rotor carrier of the disk carrier displaces the locking element radially, so that it can develop in the axial direction no blocking effect.

Due to a radial bias, the locking element, which is preferably designed as a spring ring, automatically moves back radially when it is covered in the radial direction of the recess or the groove in the plate carrier, namely radially into the recess or groove into it. This is also made possible by the fact that the tool, which was previously stuck in the access openings, was pulled out of these.

One with the in 1 illustrated hybrid module 10 coupled intermediate shaft 32 of the hybrid module 10 For example, coupled via a (not shown here) damper, such as a dual mass flywheel, with an output shaft of an internal combustion engine, not shown, or connected.

The output side of an input side 11 of the hybrid module 10 performing intermediate wave 32 is non-rotatable with an outer disc carrier 54 a disconnect clutch 50 coupled. Slats of the plate pack 51 the separating clutch 50 are doing in a ring cylinder space 91 that of a plate carrier 90 is formed, arranged, namely here on the outside 94 a first hollow cylinder 93 of the disk carrier 90 ,

The plate carrier 90 has a front-side connecting element 110 on, with the first hollow cylinder 93 radially with a second hollow cylinder 95 is coupled. On the inside 96 are disk sets 71,81 a first part clutch device 70 and a second partial clutch device 80 , which together form a double clutch device 60 train, arranged.

An inner disc carrier 74 the first part clutch device 70 is set to from the plate pack 71 the first part clutch device 70 to transmit a torque to a first transmission input shaft, not shown here.

An inner disc carrier 84 the second part clutch device 80 is set to from the plate pack 81 the second part clutch device 80 to transmit a torque to a second transmission input shaft, not shown here. The two inner disk carrier 74,84 form the output side 12 of the hybrid module 10 , On the outside 94 of the first hollow cylinder 93 as well as on the inside 96 of the second hollow cylinder 95 are takeaway facilities 100 , preferably in the form of gears, arranged in a form-fitting manner with lamellae of the disk packs 51 , 71.81 of the separating clutch 50 , the first partial clutch device 70 and the second part clutch device 80 interact.

The first hollow cylinder 93 and the second hollow cylinder 95 of the disk carrier 90 are arranged coaxially with each other.

The plate carrier 90 has on the outside 94 the first hollow cylinder as well as on the inside 96 of the second hollow cylinder 95 in each case a support element 101, here in the form of a notch or groove. This support element 101 serves for receiving as well as axial support of the counter plate 73 the first part clutch device 70 on the inside 96 of the second hollow cylinder 95 and the inclusion and axial support of the counter-plate 53 the separating clutch 50 on the outside 94 of the first hollow cylinder 93 when the respective disk packs 51,71 are axially loaded by the respective actuation systems 52,72 and are supported on the counter plates 53,73.

It can be seen that an axially acting actuator 83 for actuating the second part clutch device 80 axially through the disk pack 71 the first part clutch device 70 extends through.

An actuator or an actuation system 52 for actuating the separating clutch 50 is on one axial side of the hybrid module 10 provided in a state in which the hybrid module 10 is installed in a drive train of a hybrid vehicle, which faces the internal combustion engine. Actuators or actuation systems 72, 82 for actuating the first part-clutch device and the second part-clutch device 80 are on one side of the hybrid module 10 provided in a state in which the hybrid module 10 is installed in the drive train of the hybrid vehicle, facing the transmission. This means that the actuator or the actuation system 52 for actuating the separating clutch 50 an actuating direction, in an opposite direction with respect to the actuating direction of the actuating systems 72,82 and actuators for actuating the first part clutch device 70 and / or the second part clutch device 80 is directed.

The plate carrier 90 for supporting lamellae of disk packs 71, 81 from the first partial coupling device 70 and the second part clutch device 80 is as a with respect to a rotor carrier 30 of the hybrid module 10 for the rotationally fixed arrangement of a rotor 22 an electric machine 20 provided separate component.

The rotor carrier 30 and the plate carrier 90 are about torque transmitting elements 120 so rotatably connected or coupled to each other that a rotation of the rotor carrier 30 a rotation of the disk carrier 90 causes. The torque transmitting element 120 can be realized for example by means of a milling, a screw, a bore, a pinning or the like.

The plate carrier 90 is non-rotatable in one of the rotor carrier 30 trained space on the rotor arm 30 arranged.

The rotor carrier 30 serves to receive or arrange one on the radial inside of a stator 21 an electric machine 20 arranged rotor 22 ,

The rotor 22 as well as the rotor carrier 30 and the plug-in module 40 are all on a common axis of rotation 1 arranged substantially coaxially.

The rotor carrier is supported by rolling bearings 140 on a housing part 31 which in turn radially on the intermediate shaft 32 supported.

Due to the design of the rotor carrier 30 and the disc carrier 90 as separate components, a the disconnect clutch 50 and the starting clutch devices, here designed as partial clutch devices 70,80, having plug-in module 40 be created in a simple way axially in the rotor carrier 30 of the hybrid module 10 can be pushed, resulting in a modular assembly of the hybrid module 10 allows.

When assembling the hybrid module 10 in the drive train or an installation of the hybrid module 10 in the drive train is the housing part 31 mounted on an output shaft of the internal combustion engine such that the output shaft relative to the housing part 31 is rotatable. An actuator or an actuation system 52 for actuating the separating clutch 50 is in a wall of the housing part 31 arranged. The rotor carrier 30 on which the rotor 22 the electric machine 20 relative to the rotor carrier 30 is arranged rotationally fixed, is so on a portion of the housing part 31 stored that the rotor carrier 30 relative to the housing part 32 is rotatable. The plug-in module 40 with the separating clutch 50 and the partial clutch devices 70, 80 become such in the rotor carrier 30 pushed in that the intermediate shaft 32 of the plug-in module 40 connected to an input side of the separating clutch 50 coupled. or is connected to the output shaft of the internal combustion engine rotatably coupled or connected. The Lamellenträger90 comes with the rotor carrier 30 connected torque transmitting.

How to continue 1 is apparent, comprises the hybrid module 10 radially between the housing part 31 and the rotor carrier 30 , the partially coaxial with the housing part 31 runs, a spacer element 150 , which is also referred to as a spacer. This spacer element 150 lies with its radial inside 151 on the radial outside of the housing part 31 and is supported there radially. The spacer element blocks 150 an axial movement of the rolling bearing 140 , which also between the rotor carrier 30 and the housing part 31 is arranged and at the the spacer element 150 opposite side to a paragraph of the housing part 1 axially supported. At the rolling bearing 140 axially opposite side is located on the spacer element 150 a fixing element 170 on, which is designed here in the form of a special mother. The internal thread 171 This special nut on an external thread 172 of the housing part 31 , The fixing element 170 or the special nut has circumferentially distributed engagement holes 163, in the form of a special tool can be inserted to rotate the fixing element and thus move it axially, and thus the distance between the fixing element 170 and the rolling bearing 140 adjust. Accordingly, in the spacer element 150 an axial Preload be generated, so that the spacer element 150 axially as a spring against the rolling bearing 140 and against the fixing element 170 suppressed. This ensures the axial position of the rolling bearing 140 ,

Between the spacer element 150 and the rotor carrier 30 is another rotary camp 160 arranged, which is a needle bearing in the embodiment shown here. This rotation warehouse 160 thus serves the further radial support of the rotor carrier 30 on the housing part 31 namely, by introducing radial forces into the rotary bearing 160 and from there to the spacer element 150 , which extends radially on the housing part 31 supported.

In the embodiment shown here, however, this is not the sole function of the spacing element 150 but it also serves to supply or adjust a lubricant volume flow in the of the plug-in module 40 radially enclosed space in which the coupling means 50,70, 80 are located. For this purpose, the spacer element comprises a passage opening 180 , the part of the flow path 181 of the lubricant. This passage opening 180 Aligns in the radial direction with one on the radially outer side of the spacer element 150 arranged passage 190 in the housing part 31 , and a passage disposed on the radially inner side of the spacer 150 191 in the rotor carrier 30 These two passages 190, 191 also form part of the flow path 181 form. By dimensioning the passage opening 180 and the positioning of the spacer element 150 can the clear width of the flow path 181 and thus the volume flow of a lubricant to be supplied can be adjusted.

Each of the axially adjacent coupling devices 70,80 is associated with a pressure element 85,86. The pressure element 75 the first coupling device 70 supports axially directly or directly on the disk pack 71 the first part clutch device 70 from.

The pressure element 85 the second part clutch device 80 rests indirectly on the disk pack 81 the second part clutch device 80 , namely here on the axially acting actuator 83 , by lamellae of the disk set of the first part clutch device 70 leads.

Each of the two partial coupling devices 70,80 is also associated with a plate spring 76,86. These disc springs 76,86 are based with their respective radially outer edge 200 on the inside 96 of the second hollow cylinder 95 of the disk carrier 90 from. For this purpose, the plate carrier 90 at these points stepped elements 97 on.

The radially inner edge 201 a respective plate spring 76,86 acts axially against a respective pressure element 75,85. A respective pressure element 75,85 is mechanically in communication with a respective actuating system 72,82 of the two partial coupling devices 70,80.

Upon actuation of such an actuating system 20, 82, a force is transmitted axially to the respective pressure element 75, 85, which directly or indirectly transmits the axial force to a respective plate pack 71, 81. In this way, the lamellae of the disk set 71, 81 are pressed against each other and torque can be transmitted to the respective partial coupling device 70, 80. If a partial clutch device 70, 80 is to be opened again, the actuation of the respective actuating system 72, 82 is ended. A respective plate spring 76,86 now causes an axial return movement of the respective pressure element 75,85, so that the lamellae of the disk set 71,81 can solve each other.

2 shows the plate carrier 90 as a one-piece component. Visible is in particular the driver device 100 on the outside 94 of the first hollow cylinder 93 as well as on the inside 96 of the second hollow cylinder 95 is arranged. The two hollow cylinders 93 , 95b are frontally over the connecting element 110 mechanically connected.

The plate carrier 90 But can also be designed as a timely component, as from the 3 and 4 is apparent. In the case of the two-piece component is as a mechanical connection 132 between an inner part 130 and an outdoor part 131 as a mechanical connection 132 a parting line of the two individual parts adjacent to the separating clutch 50 provided, as it is in 3 is shown. This parting line or mechanical connection 132 may be a welded joint, for example.

4 shows a further alternative of the structural design of the disk carrier 90 in which the inner part 130 and the outer part 131 of the disk carrier 90 overlap each other axially and with multiple screw or with one or more welds as a mechanical connection 132 attached to each other.

In the 5 . 6 and 7 are different configurations of the requirements of the disc springs 76,86 on the plate carrier 90 shown.

From these 3 figures it can be seen that an axial opening 87 in the axially acting actuator 83 the second Part coupling device 80 a larger radial extent or a larger diameter than the outer diameter of the two plate springs 76,86. This allows for already mounted axially acting actuator 83 the possibility of subsequent use of the disc springs 76,86 in the plate carrier 90 ,

5 shows that the diaphragm spring 76 the first part clutch device and the plate spring 86 the second part clutch device 80 each on a step-shaped element 97 of the disk carrier 90 or on the inside 96 of the second hollow cylinder 95 are created and supported there axially.

6 shows an alternative embodiment in which the plate spring 86 furthermore only on a step-shaped element 97 axially supported, the plate spring 76, however, on a support ring 98 supported, which in turn axially on a step-shaped element 97 supported.

The embodiment according to 7 differs from the embodiment that is in 6 is shown in that instead of the support ring 98 a circlip 99 is arranged, on which the radially outer edge 200 the plate spring 76 axially supported.

In the 8th and 9 in each case a section of the hybrid module according to the invention is shown, wherein 9 represents the relevant area even more magnified.

It is evident here that in an axial end region 300 of the disk carrier 90 this from his second hollow cylinder 95 radially outwardly projecting mold elements 301 , so-called fingers. These radially outwardly projecting mold elements 301 penetrate the rotor carrier 30 in the radial direction, namely by arranged for this purpose recesses 303 in the rotor carrier 30 in particular in the form of slots. These recesses 303 are in the embodiment shown here in the end face 304 of the rotor carrier 30 incorporated. In this way, torque between the rotor carrier can be achieved in a simple and space-saving manner 30 and the plate carrier 90 or the insertion module formed therewith 40 transfer. To secure the axial position of the disc carrier 90 in relation to the rotor carrier 30 is on the radial inside of the rotor carrier 30 a fuse element 305 arranged, which radially into the rotor carrier 30 is embedded and by an axial abutment on the plate carrier 90 an axial displacement of the disk carrier 90 and consequently the plug-in module 40 blocked.

In the embodiment shown here it is not yet the only element which blocks an axial displacement, but also on the first hollow cylinder 93 of the disk carrier 90 is between the radial inside and the rotor carrier 30 a further element for blocking the translational degree of freedom of the disk carrier 90 arranged, namely here a spring ring 306 in a groove 309 in the rotor carrier 30 is arranged.

As another constructive element for the positive transmission of torque between the rotor arm 30 and the plate carrier 90 is a dowel pin 307 provided in the front-side connecting element 110 of the disk carrier 90 as well as in the rotor carrier 30 plugged.

For the purpose of realizing a structurally simple operation of the disconnecting clutch shown 50 is in the rotor carrier 30 as well as in the front-side connecting element 110 at least one passage opening 308 , Preferably a plurality of such passage openings 308 , provided by a clutch actuator 310 through leads to the loading of the slats of the separating clutch 50 with an actuating force.

10 shows a further section of a hybrid module according to the invention, namely here in particular the separating clutch 50 , which are also inside the plate carrier 90 is arranged. It can be seen that the plate carrier 90 with its radial inner boundary on the rotor carrier 30 is applied. To secure the axial position of the disk carrier 90 or the plug-in module equipped therewith 40 in relation to the rotor carrier 30 is a locking element, here in the form of the spring ring shown 306 , between rotor arm 30 and plate carrier 90 is arranged.

In the illustrated position of the spring ring 306 in which it has a larger diameter than the rotor carrier 30 , lies the spring ring 306 stress-free before and extends to the contour shown in dashed lines. After mounting the spring washer 306 on the rotor carrier 30 and before the axial insertion of the disk carrier 90 or the plug-in module equipped therewith 40 in the rotor carrier 30 represents the spring washer 306 Consequently, an axial blockage against the insertion process.

In order to enable the insertion are in the two inner disk carriers 74,84 of the first part clutch device 70 and the second part clutch device 80 axially extending through openings 400 educated. Such a passage opening 400 is also in the outer disk carrier 54 the separating clutch 50 educated. The access openings 400 are like that arranged so that they can be axially aligned with each other, as in 10 shown.

This allows the axial insertion of a tool 401 into the access openings 400 , With the tool, the radially outstanding spring ring 306 in the rotor carrier 30 be moved to allow unimpeded insertion of the disk carrier 90 in the rotor carrier 30 to enable. Preferably, a plurality of uniformly distributed through openings are in the inner disk carriers or the outer disk carrier 400 present, the simultaneous axial engagement of several tools 401 enable.

Another help when inserting the plate carrier 90 in the rotor carrier 30 is through a section with at least partially oblique course 403 on the plate carrier 90 causes. this section 403 is between the inner, first hollow cylinder 93 of the disk carrier 90 and the substantially perpendicular thereto extending end-side connecting element 110 arranged. This oblique area or there provided rounding on the plate carrier 90 causes when inserting the disk carrier 90 in the rotor carrier a wedge effect on the radially projecting spring ring 306 so that this during the insertion movement of the disk carrier 90 in the rotor carrier 30 pushed away axially inward.

With the plug-in module proposed here and the hybrid module produced therewith, units are provided which can be assembled in a simple and manual as well as automated manner with small tolerances.
