Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments of the present application.

According to a first aspect of the present application, referring to fig. 1-3, the present application provides a powertrain 100 comprising an engine 110, an air intake assembly 100a, and an electric drive assembly 130.

The electric drive assembly 130 is adapted to drive the wheels. Optionally, the electric drive assembly 130 includes at least one motor that is coupled to the wheels to drive the wheels in rotation.

Intake assembly 100a is coupled to engine 110 and is configured to deliver gas to engine 110 to enable engine 110 to burn normally to output power. The air intake assembly 100a is mounted to an electric drive assembly 130.

When the engine 110 is in normal operation, the gas in the combustion chamber expands after combustion to push the piston to move, and during the period, the expansion of the gas expands in a plurality of directions, so that acting force is generated on the engine 110, the engine 110 can vibrate to a certain extent, and meanwhile, moving parts such as a crankshaft and the like in the engine 110 vibrate in the moving process, therefore, during the normal operation of the engine 110, the vibration is inevitably generated, and the vibration quantity increases along with the increase of the set displacement of the engine 110, namely, generally, the vibration quantity of the engine 110 of 2.0T is larger than that of the engine 110 of 1.5T without vibration reduction measures.

For cost reasons, a portion of the structure of the intake assembly 100a is typically made of plastic, such as the intake manifold 120, which is not strong. That is, the connection position of the intake assembly 100a to the engine 110 is easily loosened under the influence of vibration, or the intake assembly 100a itself may be broken, resulting in air leakage of the intake assembly 100a, and the normal operation of the engine 110 is affected.

In an embodiment of the present application, the air intake assembly 100a is mounted to an electric drive assembly 130.

Although the vibration of the electric drive assembly 130 is similar to that of the engine 110, the vibration of the electric drive assembly 130 is small, the structure of the air intake assembly 100a is not easily affected, and the connection strength of the connection position of the air intake assembly 100a and the engine 110 is not easily affected, so that the electric drive assembly 130 can provide a certain support for the air intake assembly 100a, the vibration of the engine 110 can be transmitted to the electric drive assembly 130, the influence of the vibration of the engine 110 on the air intake assembly 100a is reduced, and the air leakage problem caused by the cracking or the loosening of the fixed position of the air intake assembly 100a can be improved.

The connection between the air intake assembly 100a and the engine 110 is mainly for enabling the air to enter the engine 110 through the air intake assembly 100a, for example, the air intake assembly 100a may be fixed on the engine 110 by bolts, and a sealing structure such as sealant is disposed between the air intake assembly 100a and the engine 110 to achieve sealing.

Since the intake assembly 100a of the embodiment of the present application is reduced by the influence of the vibration of the engine 110, the displacement of the engine 110 can be increased without being restricted by the structural strength of the intake assembly 100 a. Alternatively, the engine 110 is a 2.0T engine 110 or a higher displacement engine 110.

Referring to fig. 1-3, in some embodiments, at least a portion of air intake assembly 100a is positioned between engine 110 and electric drive assembly 130 to take full advantage of the space between engine 110 and electric drive assembly 130 to increase the integrity of powertrain 100.

Alternatively, the air intake assembly 100a may be partially disposed between the engine 110 and the electric drive assembly 130, and another portion may extend to a front side, a left side, a right side, or a rear side of the engine 110, or to a front side, a left side, a right side, or a rear side of the drive assembly, or the like, depending on the spatial arrangement of the vehicle model.

The front-rear direction of the present application is merely for convenience in describing the specific embodiments of the present application, and is merely for expressing the relative positional relationship, and generally refers to the front and rear in actual use or in an operating state, and may be, for example, the front and rear when mounted on the vehicle 10. Similarly, the left-right direction and the up-down direction are merely for expressing relative positional relationships, and they merely indicate approximate orientations, not absolute geometric relationships.

Referring to fig. 1-3, in some embodiments, at least a portion of air intake assembly 100a is located on a front side of electric drive assembly 130. In this manner, space on the front side of electric drive assembly 130 may be fully utilized.

Referring to fig. 1-3, 5, in some embodiments, at least a portion of the air intake component 100a located on the front side of the electric drive assembly 130 is mounted to the electric drive assembly 130.

Alternatively, the first portion of the air intake assembly 100a may be directly mounted to the electric drive assembly 130 and the second portion may be secured to the first portion, thereby constituting an indirect mounting of the second portion to the electric drive assembly 130, or each portion of the air intake assembly 100a may be directly mounted to the electric drive assembly 130, depending upon the configuration of the air intake assembly 100a, the spatial arrangement of the vehicle model, etc.

Referring to FIGS. 1-5, in some embodiments, the intake assembly 100a includes an intercooler 133 and a throttle valve 140.

The intercooler 133 is configured to cool the external air input to the engine 110, thereby reducing the volume of the external air, and to increase the density of the external air, and to increase the amount of the air input to the engine 110 when the volume of the air input to the engine 110 is constant, to improve the combustion of the engine 110, and to increase the output power of the engine 110 or the thermal efficiency of the engine 110 according to the actual situation.

Throttle 140 is used to control the amount of external air input to engine 110 such that engine 110 provides an appropriate power output under different operating conditions.

In the present embodiment, at least one of the intercooler 133 and the throttle valve 140 is mounted to the front side of the electric drive assembly 130. The impact of engine 110 vibration on intercooler 133 and throttle 140 is reduced by providing support to at least one of intercooler 133 and throttle 140 by electric drive assembly 130.

Alternatively, both the intercooler 133 and the throttle 140 are mounted to the front side of the electric drive assembly 130, or the intercooler 133 is mounted to the front side of the electric drive assembly 130 and the throttle 140 is mounted on the intercooler 133.

Because there is gas transportation between the throttle 140 and the intercooler 133, if the throttle 140 and the intercooler are respectively mounted to the electric drive assembly 130, the positioning accuracy of the throttle 140 and the intercooler on the drive assembly needs to be satisfied at the same time, and the processing requirement is high. As with fig. 1-5, in some embodiments, the intercooler 133 is mounted to a front side of the electric drive assembly 130, and the throttle 140 is fixedly coupled with the intercooler 133. So, when specifically assembling, can assemble throttle valve 140 and intercooler 133 into a whole earlier, will wholly install to electric drive assembly 130 through intercooler 133 again, only need satisfy the positioning accuracy of intercooler 133 on drive assembly under this mounting means, the processing requirement is lower, easy to assemble.

Alternatively, throttle 140 and intercooler 133 may be secured by a clamp connection, a flange connection, a threaded connection, or the like.

Referring to fig. 1-5, in some embodiments, the intercooler 133 includes an intake end 133a and an exhaust end 133b, and the exhaust end 133b is fixed to the throttle 140 by a flange connection. The fixation of the throttle valve 140 and the intercooler 133 is realized in a flange connection mode, so that the sufficient rigidity of the connection part can be ensured, the stability of the throttle valve 140 is ensured, and the sealing reliability is high. At this time, the external air passes through the intercooler 133 and the throttle valve 140 in order into the engine 110. Compared with the scheme that external air sequentially passes through the throttle valve 140 and the intercooler 133 and then enters the engine 110, in the embodiment, the characteristic that the volume of the throttle valve 140 is smaller than that of the intercooler 133 is utilized, the air inlet hose 135 and the air inlet manifold 120 between the throttle valve 140 and the engine 110 are convenient to set, and the integration level is improved. Illustratively, as shown in fig. 1, the intake hose 135 can be at least partially disposed in the L-shaped space formed between the throttle valve 140 and the intercooler 133, making full use of the L-shaped space between the throttle valve 140 and the intercooler 133 to promote integration.

Illustratively, the air outlet end 133b is provided with a first flange surface and a plurality of first mounting holes (not shown) located at the periphery of the first flange surface, the air throttle 140 is provided with a second flange surface and a plurality of second mounting holes 141 located at the periphery of the second flange surface, and the first and second mounting holes 141 are used for being matched with fasteners to lock the first and second flange surfaces. By the arrangement of the two matched flange surfaces, the throttle valve 140 is convenient to position and fix on the intercooler 133.

Alternatively, in some embodiments, throttle 140 may be fixedly coupled to air intake end 133a of intercooler 133 via a flange. At this time, the external air is introduced into the engine 110 through the throttle valve 140 and the intercooler 133 in this order. Compared to the embodiment in which the throttle valve 140 is provided at the air outlet end 133b of the intercooler 133, the present embodiment provides the throttle valve 140 at the air inlet end 133a of the intercooler 133, which can reduce the pressure loss of the external air, and at the same time, the intake air amount of the external air after the throttle valve 140 is adjusted can be responded quickly.

Because throttle 140 is heavy, even if it is mounted to electric drive assembly 130 to reduce some of the vibrations, it may still have some impact on intake manifold 120 if a rigid connection is used with intake manifold 120.

Referring to fig. 1-5, in some embodiments, the intake assembly 100a further includes an intake manifold 120 and an intake hose 135. An intake manifold 120 is connected to the engine 110 for distributing external air to the various cylinder passages of the engine 110. The intake manifold 120 is connected to the throttle valve 140 via the intake hose 135.

By adopting the scheme, the throttle valve 140 is directly or indirectly mounted to the electric drive assembly 130, and the throttle valve 140 is connected with the air inlet manifold 120 through the air inlet hose 135, so that the stress and vibration of the air inlet manifold 120 caused by the throttle valve 140 are reduced, the mode of the air inlet manifold 120 can be effectively improved, the noise, vibration and harshness (NVH, noise, vibration, harshness) performance can be improved, manifold cracking and mounting bolt loosening caused by excessive vibration of the air inlet manifold 120 can be avoided, and the air leakage risk is reduced, so that the stability and durability of the power assembly 100 are improved.

In addition, the design of the air inlet hose 135 is flexible, the trend of the air inlet hose 135 can be adjusted according to the actual space arrangement requirement (such as the arrangement positions of the air inlet manifold 120 and the throttle valve 140), the arrangement space is greatly saved, and different arrangement requirements are met. Not only can the installation of the intake hose 135 be facilitated, but also the transmission of vibrations between the intake hose 135 and the throttle valve 140 can be reduced.

Referring to FIG. 3, in some embodiments, the intake hose 135 is coupled to the throttle valve 140 via a first clamp 136 and/or the intake hose 135 and the intake manifold 120 are coupled via a second clamp 137.

It will be appreciated that at least one of the intake manifold 120 and throttle 140 may be coupled to the intake hose 135 using a clamp connection.

By adopting the connection scheme, the air inlet hose 135 is assembled with the air inlet manifold 120 and the throttle valve 140 through clamp assembly, a bolt sleeve mounting space is not required to be reserved, the assembly and disassembly are easy, and the assembly efficiency is effectively improved.

Referring to fig. 1,2, and 8, in some embodiments, at least a portion of the intake manifold 120 is positioned between the engine 110 and the electric drive assembly 130 to improve the compactness of the powertrain 100.

Referring to fig. 1-3 and 5, in some embodiments, a front side of the electric drive assembly 130 is provided with a suspension 134 adapted to connect the electric drive assembly 130 to a vehicle frame, serving as a support and vibration isolator, reducing transmission of vibrations of the electric drive assembly 130 (including at least one of vibrations generated by the electric drive assembly 130 itself and vibrations transmitted by the engine 110) to the vehicle frame, and buffering impacts transmitted to the electric drive assembly 130 by the vehicle frame due to road conditions.

Alternatively, the suspension 134 may be one of a pure glue suspension, a hydraulic suspension, an air suspension, or the like.

In the present embodiment, the air intake assembly 100a located at the front side of the electric drive assembly 130 is mounted to the suspension portion 134, so that vibration isolation between the air intake assembly 100a and the electric drive assembly 130 is achieved, thereby reducing vibration of the engine 110 or transmission of impact force of the vehicle frame to the air intake assembly 100a through the electric drive assembly 130.

In some embodiments, at least one of the intercooler 133 and the throttle 140 is mounted to the suspension 134, reducing the transmission of vibrations of the engine 110 or impact forces of the vehicle frame to the throttle 140 and the intercooler 133 through the electric drive assembly 130, improving the problem of the connection location being prone to loosening by vibrations.

Alternatively, the intercooler 133 and the throttle valve 140 are each directly mounted to the suspension 134, or the intercooler 133 and the throttle valve 140 are fixedly connected and one of them is mounted to the suspension 134.

The horizontally opposed motors 110 are low in height and are conveniently stacked above the electric drive assembly 130 to improve the integrity of the powertrain 100.

Wherein, optionally, an air inlet is arranged below the engine 110 and connected with the air inlet component 100a, and an air outlet is arranged above the engine 110, so as to avoid the influence of exhaust heat on the electric drive assembly 130.

Referring to fig. 1, 2, and 8, in some embodiments, the engine 110 includes a cylinder head 111. The cylinder heads 111 are provided in two, and the two cylinder heads 111 are disposed opposite each other in the left-right direction.

For gas distribution suitable for the two cylinder heads 111, the intake manifold 120 includes an intake portion 121 and two gas-dividing portions 122, and the two gas-dividing portions 122 and the two cylinder heads 111 are connected correspondingly. The outside air is first introduced into the air inlet portion 121 through the throttle and air inlet hose 135, and then is distributed from the air inlet portion 121 to the air distribution pipe portions 122 on both sides, thereby realizing control of cylinders on both sides by the same throttle valve 140.

Specifically, the gas-dividing pipe 122 has a first type of connection structure 122a. The gas distributing pipe portion 122 is connected to the cylinder head 111 through a first type of connection structure 122a.

For example, the number of bolt holes of each gas-dividing pipe portion 122 has a value ranging from 3 to 5.

Referring to fig. 1, 2 and 8, in some embodiments, the air-distributing portion 122 is located between the motor 110 and the electric drive assembly 130, the space between the motor 110 and the electric drive assembly 130 is fully utilized, and the motor 110 and the electric drive assembly 130 can protect the air-distributing portion 122.

Referring to fig. 1, 2 and 8, in some embodiments, the powertrain 100 further includes an oil pan 112. The oil pan 112 is used for storing lubricating oil of the engine 110, at least part of the oil pan 112 is located in a space surrounded by the two air distribution pipe portions 122, the air inlet portion 121, the engine 110 and the electric drive assembly 130, so that the height space occupied by the air inlet manifold 120 can be reused, the compactness of the arrangement of the air inlet manifold 120 and the engine 110 is improved, and the overall height of the power assembly 100 is optimized.

Referring to fig. 8, in some embodiments, the air intake portion 121 is fixedly connected to the oil pan 112, so as to further improve the connection reliability of the intake manifold 120.

The cylinder body is arranged between the two cylinder covers 111, the cylinder cover 111 is fixedly connected with the electric drive assembly 130, and/or the cylinder body is fixedly connected with the electric drive assembly 130. By adopting the scheme, the engine 110 and the electric drive assembly 130 are connected and fixed, so that the vibration of the engine 110 is directly transmitted to the electric drive assembly 130 through the connection between the engine 110 and the electric drive assembly 130, the influence of the vibration of the engine 110 on the air inlet assembly 100a is further reduced, and the air leakage problem caused by the cracking or the loosening of the fixed position of the air inlet assembly 100a is further improved.

Alternatively, the cylinder head 111 and the cylinder block are both fixedly connected to the electric drive assembly 130, or one of the cylinder head 111 and the cylinder block is both fixedly connected to the electric drive assembly 130.
