Definitions
- Hydrokinetic coupling device in particular for a motor vehicle.
- the present invention relates to hydrokinetic coupling devices, in particular for a motor vehicle, as described in document O-A-94/07058.
- This device has a generally transverse orientation wall capable of being linked in rotation to a driving shaft and carrying a guide ring centrally attached.
- This wall belongs to a housing surrounding a turbine wheel integral in rotation with a driven shaft.
- a piston is mounted mobile axially sealed along said ring and defines with the wall and the ring a variable volume chamber delimited externally by a disc and friction linings adapted to be clamped respectively between the piston and the disc and between the disc and wall.
- Each friction lining is integral with one of the disc-piston-transverse wall elements respectively, between which it is intended to be clamped.
- the transverse wall swells outward when the hydrokinetic coupling device is rotated by the drive shaft due to the presence of oil in the housing, forming the housing.
- the transverse wall swells more centrally than at the level of the friction linings.
- the piston may, following the aforementioned swelling, no longer cover the seal, acting between it and the guide ring, when the locking clutch is disengaged.
- the object of the present invention is to overcome these drawbacks in a simple and economical manner and to respond to this wish.
- stop means facing the transverse wall and carried by the transverse wall, are provided to limit the movement of the piston in the direction opposite to the transverse wall. Thanks to the invention, the phenomena of relative displacement between the piston and the guide ring are reduced.
- the piston follows the movement of the transverse wall and the axial size is reduced at the level of the guide ring.
- This guide ring in all circumstances provides a good reach for the piston which cannot escape from it when the locking clutch is released (or released). This stop therefore makes it possible to limit the movement of the piston in the direction of the turbine wheel. Thus this piston does not risk interfering with the hub of the turbine wheel or with a flange of a torsion damper.
- the stop means according to the invention make it possible to provide the seal, which is thus covered in all circumstances, for example by the piston.
- the variable volume chamber is thus always sealed.
- This stop also makes it possible to provide tangential elastic tongues (by limiting the camber thereof) involved in certain embodiments between the piston and the transverse wall for rotationally connecting the piston with said transverse wall and this with the possibility of axial movement. piston.
- the abutment means can be mounted in said chamber and be formed by means of a drive piece fixed to the transverse wall and used for fixing the tangential tongues intervening in this case between the piston and said part.
- This arrangement promotes the reduction of one axial size between the guide ring and the hub which is integral with the turbine wheel.
- FIG. 1 is a half-view in partial axial section of a hydrokinetic coupling device according to the invention
- FIG. 3 is a view along line 3-3 of Figure 2; - Figure 4 is a view similar to Figure 3 for another embodiment.
- a hydrokinetic coupling device comprises, arranged in the same sealed housing filled with oil and forming a housing, a torque converter and locking clutch 1.
- This casing here metallic, forms a driving element and is suitable for being linked in rotation to a shaft leading to the crankshaft of the internal combustion engine in the case of an application to a motor vehicle.
- This annular-shaped casing is formed by two half-shells facing each other and fixed in a sealed manner at their external periphery, usually by welding.
- the first half-shell 2,3 is suitable for being linked in rotation to the driving shaft and comprises a generally annular wall 2 of transverse orientation extended at its external periphery by a cylindrical wall 3 generally of axial orientation.
- the second half-shell not shown for simplicity as well as the reaction wheel of the converter, is shaped so as to define an impeller wheel with vanes integral with the internal face of this half-shell.
- blades face the blades of a turbine wheel 4 fixed by riveting or welding to a hub web in one piece with an internally fluted hub 5 for its rotational connection to a driven shaft, namely the input shaft of the gearbox in the case of a tin application motor vehicle.
- This shaft is hollowed out internally to form a channel allowing the oil to access a guide ring 6 located axially between the hub 5 and the transverse wall 2 while being integral with said wall 2.
- This ring 6 is centrally provided with a centering nose 7 projecting axially and is fixed centrally by welding, of which the cord is seen (FIG. 1) at 60, to the wall 2 provided for this purpose centrally with an orientation sleeve axial 61 facing outwards into which the centering nose 7 enters.
- the ring 6 is also provided in one piece with a flange 8 of transverse orientation. The ring 6 is thus shouldered and is in contact by its flange 8, after its fixing by welding, with the internal face of the wall 2 turned towards the hub 5.
- a piston 9 is mounted to slide axially along the annular external periphery of the flange 8, provided with a groove for mounting an annular seal 29.
- the piston 9 has centrally an axially oriented sleeve turned towards the wall 2 for its sliding along the flange 8.
- the piston 9 delimits with the ring 6, the wall 2 and a disc 10, bearing, for example by gluing on each of its faces, friction linings 11, a chamber 30 variable volume supplied by the ring 6 having for this purpose not referenced bores supplied by the channel of the aforementioned driven shaft.
- the holes affect the flange 8 and have inclined portions opening into a blind hole, which the ring 6 has centrally.
- the disc 10 is located at the outer periphery of the piston 9 and has at its outer periphery, radially beyond the piston 9, lugs, with an axial orientation part, each penetrating into a notch, which has a guide washer 12 at its internal periphery.
- the disc 10 is thus linked in rotation, with axial mobility, to the guide washer 12 by a connection of the tenon-mortise type 13 with lugs and notches.
- the notches are produced in a transverse portion 14 of the guide washer 12.
- This transverse portion 14 is extended by an annular portion 15 of axial orientation serving to radially maintain coil springs 16, internally retained by an annular retention portion 17 of a web 18 extended inward by a flange 19 fixed by riveting to the web of the hub 5 at the same time as the turbine wheel 4 provided for this purpose with tabs (not referenced) at its internal periphery.
- the fixing can be carried out by welding.
- the flange 19 has a series of holes (not referenced) for circulation of the oil between the piston 9 and the wheel 4.
- the web 18 can be fixed directly by welding to the turbine wheel.
- the veil 18 has support portions 20 for the circumferential ends of the springs 16. These portions 20 are formed by means of support punctures, of sinuous shape, extending from the internal periphery to the external periphery of the portion holding 17 of the web 18.
- This portion 17 is in the form of a half-shell and is offset axially relative to the portions 14, 15 of the guide washer 12 also forming a half-shell.
- the guide washer 12 is provided at its axial portion 15 with inward material deformations 21 for support of the ends of the springs 16.
- the portion 14 also has lugs 22 for support of the ends of the springs 16.
- the locking clutch 1 comprises a torsion damper 23 implanted for the most part between the turbine wheel 4 and the wall 2 at the external periphery of the first shell, with an inlet part 12 disposed radially above the piston. 9 and the linings 11, consisting of the guide washer 12 in the form of a half-shell 14, 15, coil springs 16 and an outlet part constituted by the veil 18 also in the form of a half-shell at its outer periphery.
- the outlet part 18 is linked in rotation to the turbine wheel 4, here to the hub 5 thereof, while the inlet part 12 is linked in rotation to the disc 10, projecting radially with respect to the piston 9.
- the inlet part 12 is therefore disengageably linked via the disk 10 and the linings 11 to the drive shaft, said disk 10 with its linings being suitable for being disengageably clamped between the piston 9 and the wall 2 forming against -piston.
- the disc 10 is resiliently coupled to the hub 5 and to the wheel 4.
- the turbine wheel 4 is driven in rotation by the impeller wheel thanks to the circulation of fluid contained in the sealed housing or casing and after starting the vehicle, the locking clutch 1 allows, to avoid the phenomena of sliding between the wheels turbine and impeller, a direct connection (or bridging) of the driven shaft with the driving shaft and this by tightening the friction linings 11 and the disc 10 between the piston 9 and the counter-piston 2 with direct drive of the tree driven by the half-shell 2.3.
- the piston 9 is linked in rotation to the wall 2 of the first half-shell 2,3 by tangential elastic tongues 40 distributed regularly circumferentially, here four sets of tongues (FIG. 3).
- tongues 40 allow axial movement of the piston.
- the tongues are coupled to the transverse wall 2 by means of an annular piece 44, here metallic, tightly secured to the wall 2 here by rivets 45 came here in one piece, for example by extrusion.
- the annular part 44 has from place to place tabs 48 offset axially with respect to its main part for fixing to the wall 2.
- the tongues 40 formed here from a stack of two tongues, are secured to the one of their ends by rivets 43 on the legs 48.
- tongues 40 extend generally tangentially with respect to a circumference of the assembly.
- fixing means 41, 42 are used, which, while being capable of passing generally through the tongues 40 and the piston 9, have two parts, namely, a first part 41, which, in advance, is subject to the tongues 40, on the side of these opposite the piston 9, and a second part 42, which, in order to come into engagement with the first part 41, does not requires intervention only on the side of the piston 9.
- the tongues 40 extend in the volume which extends radially between the friction linings 11 and the axis of the assembly, that is to say in the chamber 30 and axially between the wall 2 and the piston 9.
- the fixing in two parts 41,42 is of the crimped bolt rod type.
- the first part 41 comprises a rod with a bearing head in contact with the face of the tongues 40 facing the wall 2.
- the bearing head is disposed in the chamber 30.
- the rod plays through the associated bore of the piston 9 and comprises a first smooth section and a first notched section.
- This part 41 is secured by force fitting its smooth section or alternatively by knurling or gluing to the tongues 40.
- the second part 42 consists of a crimping ring, which comprises, on the side of the piston, a base of larger diameter to prevent its creep in the bore of the piston.
- the second part acts on the side of the face of the piston 9 opposite to the tongues 40, that is to say outside of the chamber 30.
- the ring 42 is crushed so that it comes into engagement with the notched section of the rod 41.
- rivets of the "POP" type can be used.
- the first part may consist of a nut or a screw fixed for example by gluing to the tongues 40 and the second part may consist of a screw or a nut.
- the ring 6 therefore follows the movement of the wall 2 so that a relative movement occurs between the piston 9 and the ring 6.
- the invention proposes creating stop means 50 facing the transverse wall 2 and carried by the said wall 2, in order to limit the movement of the piston 9 in the opposite direction from the transverse wall 2.
- the piston 9 therefore follows the movement of the central part of the wall 2 and mates with the ring 6.
- the piston sleeve covers in all circumstances the seal 29 which is thus formed.
- the movement of the piston 9 in the direction of the flange 19 and of the turbine wheel 4 is limited so that the distance between the piston 9 and the lining 11 can be controlled when the clutch 1 is released.
- the distance between the piston 9 and the lining 11 (FIG. 1) can be reduced so that the response time for tightening the clutch 1 (bridging) is reduced.
- these abutment means 50 are located in the chamber 30 and are formed by means of the part 44 used for fixing the tongues 40 and fixed to the wall 2.
- the tangential tongues 40 are here extended circumferentially by 47 beyond the attachment in two parts 41, 42 of the tongues 40 to the piston 9.
- each of the extensions 47 is suitable for cooperating with a stop 46 facing the wall 2 ( Figures 2 and 3).
- This stop 46 belongs to the means 50 and extends locally parallel to the wall 2. It is formed by stamping in favor of the lugs 48 axially offset with respect to the main part of the annular part 44.
- a lug 48 therefore has one end for fixing a rivet 43 and a stop 46.
- the piece 44 is formed generally in section of the brackets (or claws) with a part of axial orientation surrounding the free end of the tongues 40 (the extension 47), extended by a part d transverse orientation 46 forming the stop means according to the invention and suitable for cooperating locally with the face of the tongues 40 facing the piston 9, that is to say with the dorsal face of the tongues 40.
- the head of the part 41 of the attachment 41, 42 can be extended circumferentially at 147 so as to come into engagement with the stop 46.
- the extension 147 has an axial projection suitable for cooperating with the stop 46. It is therefore the dorsal face of the head of the part 41 which serves as a buttress for the stop 46.
- each head of the rivet 43 can be extended at 247 to form the abutment means 50.
- the dorsal face of the tongues 40 is intended to cooperate with said extension 247 more precisely with the face of the latter facing towards the piston.
- stop means 50 make it possible to provide the tongues 40 by limiting their bending, in particular when the locking clutch 1 is disengaged.
- the hub 5 can therefore come as close as possible to the ring 6. It will be appreciated that the position of the stop 46 relative to said extension 47,147,247 is determined to avoid any interference between the piston 9 and the flange 19 and the hub 5.
- the fixing means 41, 42 can consist of simple rivets or of screws or bolts. To do this, a driving part 44 - tangential tabs 40 - piston 9 sub-assembly is created in advance.
- the piston 9 of the sub-assembly is centered, then the drive part is fixed by laser transparency welding to the transverse wall 2. This welding is carried out, for example on the side from the face of the transverse wall 2 facing away from the piston 9. This welding affects the thickness of the wall 2 and partly the thickness of the drive piece 44. Afterwards, the centering device is removed to mount the ring guide 6 and weld it in 60 to the sleeve 61.
- the aforementioned sub-assembly includes stop means according to the invention.
- the tangential tongues 40 and the drive part 44 are located radially in a region where the transverse wall 2 extends in axial projection, in the direction opposite to the piston 9 and to the turbine wheel 4, relative to the central part of said wall.
- the present invention is not limited to the embodiment described.
- the torsional damper 23 can have another shape, for example that described in document US-A-5,209,330.
- one of the linings 11 can cooperate indirectly with the transverse wall 2.
- the linings are clamped directly or indirectly between the piston and the wall 2.
- the friction linings 11 instead of being secured by bonding or brazing the disc 10 can be secured respectively to the piston 9 or to the wall 2, for example by bonding or brazing so that each friction lining is secured to one of the elements respectively piston - transverse wall between which it is intended to be clamped.
- the structure of the connection 13 can be inverted, the disc 10 then having mortises in which the pins of the guide washer 12 engage.
- the disc 10 can be coupled by a mortise-stud type connection to a crown attached to the turbine wheel 4. In this case the disc 10 is rigidly coupled to the turbine wheel 4.
- stops 46.247 depends on the applications. Thus some tongues may not be associated with stop means.
- the seal 29 can be carried by the piston 9, more precisely by the sleeve thereof.
- stop means are favorable for obtaining a controlled sliding between the disc 10 and the piston 9 - wall 2 assembly.
- the friction linings 11 can, for their cooling during said controlled sliding, be provided with grooves, as for example described in the document US-A-5,339,230.
- the grooves may be in the form of spiral portions.
- the piston 9 can be linked in rotation, with axial mobility, to the transverse wall 2 by an additional piece riveted to the piston as described in document US-A-5,209,330.
- the connection can be made using complementary grooves intervening between the external periphery of the flange 8 and the internal periphery of the central sleeve of the piston 9.
- stop means may consist of rivet heads integral with piston 9 and cooperating with stop means similar to the stop means 46 of FIG. 3. These stop means are then carried by a part similar to the part 44 of FIG. 3, said part being devoid of a tongue, while said rivets comprise a head with an extension similar to the extension 147 of FIG. 4.
- the rivets 43 can be eliminated, the tongues 40 then being in one piece with the part 44 while being fixed to their free end by the means 41,42 for fixing to the piston 9.
