[0002] Dual-motor hybrid light trucks are gradually becoming a new favorite in the automotive industry due to their advantages in energy conservation, emission reduction, and power performance. In existing technologies, the suspension system is primarily designed for the weight and vibration of the engine, failing to fully consider the additional weight and higher peak torque brought by the dual-motor system. This makes the vehicle's powertrain system unable to effectively cope with the impact of high torque, resulting in poor vibration damping performance of the powertrain system.

The other end of the third bracket is used to connect to the longitudinal beam of the vehicle frame.

[0009] Furthermore, the first connecting part and the second connecting part are arranged at an angle, forming a V-shaped structure.

[0010] Furthermore, the third bracket has an L-shaped structure and includes a first connecting section and a second connecting section.

It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0040] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a powertrain system is provided.

[0041] Specifically, the powertrain system includes an engine 1, a transmission 2, and an electric motor 3. The engine 1 has two first suspension components 4 at its front, symmetrically arranged along the width of the engine 1, which are used to connect to the vehicle frame. The transmission 2 includes a front housing and a rear housing. The front housing is connected to the engine 1, and the rear housing has two second suspension components 5. The two first suspension components 4 are symmetrically arranged along the width of the transmission 2, and the second suspension components 5 are used to connect to the vehicle frame. There are two electric motors 3, located on either side of the front housing along the width of the transmission 2. Each electric motor 3 has a third suspension component 6, which is used to connect to the vehicle frame.

[0042] In the embodiments of this application, first suspension components 4 are respectively provided on both sides of the engine 1, and the engine 1 is connected to the vehicle frame through the first suspension components 4; second suspension components 5 are respectively provided on both sides of the rear housing of the gearbox 2, and the gearbox 2 is connected to the vehicle frame through the second suspension components 5; third suspension components 6 are provided on both sides of the motor 3 located on the front housing of the gearbox 2, and the motor 3 is connected to the vehicle frame through the third suspension components 6; the powertrain system uses six sets of suspension components to connect to the vehicle frame, which not only reduces the pressure on a single suspension point by reasonably distributing the load of each suspension point and effectively disperses the mass of the powertrain, but also effectively copes with the peak torque of the motor 3 through the third suspension components 6, thereby reducing the vibration of the powertrain caused by torque changes and improving the vibration reduction performance of the entire system.

[0043] Furthermore, the first suspension assembly 4 is positioned near the bottom of the engine 1, the second suspension assembly 5 is positioned near the top of the motor 3 and near the rear housing, and the third suspension assembly 6 is positioned near the top of the gearbox 2.

[0044] In the embodiments of this application, the first suspension assembly 4 is positioned close to the bottom of the engine 1, thus avoiding the influence of heat sources above the engine 1 while being close to the vehicle frame. It also facilitates avoiding components such as the cooling system and intake system, reducing interference with the layout of accessories surrounding the engine 1. The motor 3 is located on both sides of the front housing, protruding outwards along the width direction of the vehicle frame. The second suspension assembly 5 is positioned close to the top of the motor 3, thus reducing the risk of collision with other parts while being close to the vehicle frame. The third suspension assembly 6 is positioned close to the top of the transmission 2, thus avoiding interference with the exhaust system or other pipelines at the bottom of the transmission 2 while being close to the vehicle frame.

[0045] like Figure 1 As shown, the first suspension assembly 4 is located near the front of the engine and near the bottom of the engine 1. The second suspension assembly 5 is located behind the motor 3, that is, between the motor 3 and the rear housing, and the second suspension assembly 5 is connected to the top of the motor 3. The third suspension assembly 6 is located near the rear end of the rear housing and is connected to the top of the rear housing.

[0046] Further, the first suspension assembly 4 includes a suspension A41 and a first bracket 42. The suspension A41 includes a connector A411, a connector B412, and a first elastic member 413. One end of the first elastic member 413 is connected to the connector A411, and the other end is connected to the connector B412. The first elastic member 413 can undergo elastic deformation to change the distance between the connector A411 and the connector B412. One end of the first bracket 42 is connected to the housing of the engine 1, and the other end is connected to one of the connectors A411 and B412. The other of the connectors A411 and B412 is used to connect to the crossbeam 7 of the vehicle frame.

[0047] In the embodiments of this application, the suspension A41 includes a connector A411, a connector B412, and a first elastic member 413. The engine 1 is connected to one side of the suspension A41 via a first bracket 42, and the other side of the suspension A41 is connected to the crossbeam 7 of the frame. The vibration generated by the operation of the engine 1 is absorbed by the deformation of the first elastic member 413, thereby reducing the direct impact of the vibration of the engine 1 on the frame.

[0048] like Figure 2As shown, the suspension A41 includes a connector A411, a connector B412, and a first elastic element 413. Connectors A411 and B412 are both rectangular plates, and the first elastic element 413 is a rectangular rubber pad. The first end face of the first elastic element 413 is connected to the connector A411, and the second end face is connected to the connector B412. Connectors A411 and B412 are arranged parallel to each other. A first limiting element 4111 is provided at the edge of one end of connector A411. This first limiting element 4111 is a flange extending towards connector B412. By abutting against connector B412, the deformation of the first elastic element 413 is limited, preventing damage due to excessive deformation. The first bracket 42 is integrally formed on the housing of the engine 1. The first bracket 42 is connected to the side of the connector B412 opposite to the first elastic member 413. The side of the connector A411 opposite to the first elastic member 413 is connected to the crossbeam 7 of the frame.

[0049] Further, the second suspension assembly 5 includes: a suspension B51, a second bracket 52, and a third bracket 53. The suspension B51 includes a connector C511, a connector D512, and a second elastic member 513. One end of the second elastic member 513 is connected to the connector C511, and the other end is connected to the connector D512. The second elastic member 513 can undergo elastic deformation to change the distance between the connector C511 and the connector D512. The second bracket 52 has a first connecting portion 521 and a second connecting portion 522. The first connecting portion 521 is connected to the housing of the motor 3, and the second connecting portion 522 extends away from the motor 3 along the width direction of the motor 3. The second connecting portion 522 is connected to one of the connectors C511 and D512. One end of the third bracket 53 is connected to the other of the connectors C511 and D512, and the other end is used to connect to the longitudinal beam of the vehicle frame.

[0050] In the embodiments of this application, the suspension B51 includes a connector C511, a connector D512, and a second elastic member 513. The motor 3 is connected to one side of the suspension B51 through a second bracket 52, and the other side of the suspension B51 is connected to the longitudinal beam of the frame through a third bracket 53. The vibration generated by the operation of the motor 3 is absorbed by the deformation of the second elastic member 513, thereby reducing the direct impact of the vibration of the motor 3 on the frame.

[0051] like Figure 3As shown, the suspension B51 includes a connector C511, a connector D512, and a second elastic member 513. Connector C511 has a U-shaped structure, with its two opposite sides serving as second limiting members 5111. Connector D512 is a rectangular plate, and the second elastic member 513 is a rectangular rubber pad. Connectors C511 and D512 are positioned opposite each other to form a rectangular groove. The second elastic member 513 is located within this groove. The first end face of the second elastic member 513 is connected to connector C511, and the second end face is connected to connector D512. The first end face of the second elastic member 513 is parallel to the second end face of the second elastic member 513. The second limiting member 5111 abuts against connector D512 to limit the deformation of the second elastic member 513, preventing damage due to excessive deformation. The second bracket 52 has a first connecting portion 521 and a second connecting portion 522. The first connecting portion 521 is formed on the housing of the motor 3, and the second connecting portion 522 extends away from the motor 3 along the width direction of the motor 3, that is, it extends toward the longitudinal beam of the frame. The second connecting portion 522 is connected to the side of the connector C511 opposite to the second elastic member 513. One end of the third bracket 53 is connected to the side of the connector D512 opposite to the second elastic member 513, and the other end of the third bracket 53 is connected to the longitudinal beam of the frame.

[0052] Preferably, the second limiting member 5111 is provided with a guide groove, and the connecting member D512 is provided with a guide plate. The guide plate is inserted into the guide groove to limit the deformation direction of the second elastic member 513.

[0053] Furthermore, the first connecting part 521 and the second connecting part 522 are arranged at an angle, and the first connecting part 521 and the second connecting part 522 form a V-shaped structure.

[0054] In the embodiments of this application, the first connecting part 521 and the second connecting part 522 are arranged at an angle to improve the deformation performance of the second bracket 52. When the motor 3 vibrates, the second bracket 52 can undergo slight deformation along the width direction of the frame to buffer part of the vibration of the motor 3.

[0055] Furthermore, the third support 53 has an L-shaped structure and includes a first connecting section 531 and a second connecting section 532. The first connecting section 531 is perpendicular to the second connecting section 532. The first connecting section 531 is connected to another of the connectors C511 and D512. The second connecting section 532 is used to connect to the longitudinal beam of the frame. A reinforcing rib 533 is provided between the first connecting section 531 and the second connecting section 532.

[0056] In the embodiments of this application, the third support 53 has an L-shaped structure, i.e., a bent structure, which can buffer vibration. The reinforcing ribs 533 are provided to limit the deformation of the third support 53.

[0057] Further, the third suspension assembly 6 includes: a suspension C61, a fourth bracket 62, and a fifth bracket 63. The suspension C61 includes a connector E611, a connector F612, and a third elastic member 613. One end of the third elastic member 613 is connected to the connector E611, and the other end is connected to the connector F612. The third elastic member 613 can undergo elastic deformation to change the distance between the connectors E611 and F612. One end of the fourth bracket 62 is connected to one of the connectors E611 and F612, and the other end is used to connect to the crossbeam 7 of the vehicle frame. One end of the fifth bracket 63 is connected to the other of the connectors E611 and F612, and the other end is connected to the rear housing. The fourth bracket 62, connector E611, and connector F612 form a box-shaped cavity, and the third elastic member 613 is disposed within this box-shaped cavity.

[0058] In the embodiments of this application, the suspension C61 includes a connector E611, a connector F612, and a third elastic member 613. The gearbox 2 is connected to one end of the suspension C61 via a fifth bracket 63, and the other end of the suspension C61 is connected to the crossbeam 7 of the vehicle frame via a fourth bracket 62. The deformation of the third elastic member 613 absorbs the vibration generated by the operation of the gearbox 2, thereby reducing the direct impact of the gearbox 2 vibration on the vehicle frame. The fourth bracket 62, connector E611, and connector F612 form a box-shaped cavity, and the third elastic member 613 is disposed in the box-shaped cavity. The box-shaped cavity limits the longitudinal and lateral deformation of the third elastic member 613 to avoid performance degradation caused by excessive compression or stretching of the third elastic member 613.

[0059] Preferably, the fourth support 62 is a U-shaped structure or a Z-shaped structure, and at least one of the connectors E611 and F612 is a U-shaped structure or a Z-shaped structure.

[0060] like Figure 4As shown, the suspension C61 includes a connector E611, a connector F612, and a third elastic element 613. Connector E611 has a U-shaped structure, connector F612 is a rectangular plate, and the third elastic element 613 is a rectangular rubber pad. The two opposite side plates of connector E611 act as third limiting members 6111, which abut against connector F612 to limit the deformation of the third elastic element 613 and prevent damage due to excessive deformation. Connectors E611 and F612 are arranged opposite each other to form a first rectangular groove. The third elastic element 613 is located within the first rectangular groove. The first end face of the third elastic element 613 is connected to connector E611, and the second end face is connected to connector F612. The first end face and the second end face of the third elastic element 613 are parallel. The fourth bracket 62 has a U-shaped structure and is connected to the bottom surface of the crossbeam 7 of the frame. The fourth bracket 62 and the crossbeam 7 form a second rectangular groove, which runs through the length of the crossbeam 7. The suspension C61 is located in the second rectangular groove and is connected to the fourth bracket 62 via the connector E611. One end of the fifth bracket 63 is connected to the rear housing of the gearbox 2, and the other end of the fifth bracket 63 extends into the second rectangular groove and is connected to the connector F612. The first rectangular groove runs through the length of the frame, meaning the direction of the second rectangular groove is perpendicular to the direction of the first rectangular groove. In other words, the fourth bracket 62, connector E611, and connector F612 form a box-like cavity. The two opposite side plates of the fourth bracket 62 are used to limit the deformation of the third elastic element 613, preventing damage to the third elastic element 613 due to excessive deformation.

[0061] Furthermore, such as Figure 5 As shown, two third suspension components 6 distributed along the width direction of the gearbox 2 are connected by a connecting beam 64. The connecting beam 64 is located above the gearbox 2. One end of the connecting beam 64 is connected to the fifth bracket 63 of one of the third suspension components 6, and the other end of the connecting beam 64 is connected to the fifth bracket 63 of the other third suspension component 6.

[0062] In the embodiments of this application, the connecting beam 64 connects the two third suspension components 6 together, forming a stable bridge spanning above the transmission 2. This enhances the stability of the powertrain in the lateral direction of the vehicle, especially when the vehicle is driving on uneven roads or making sharp turns. It effectively suppresses lateral displacement of the powertrain, improving vehicle handling and safety. Simultaneously, the connecting beam 64 is connected to the fifth brackets 63 of the two third suspension components 6, together forming a more robust frame structure. This effectively resists the torsional force generated by the transmission 2 under high torque conditions, ensuring that the powertrain maintains good positioning even under extreme conditions, avoiding unnecessary power loss and excessive wear of mechanical components.
