The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0029] Reference below Figure 1-Figure 4 A drive assembly 10 for a vehicle according to an embodiment of the present application is described, wherein the drive assembly 10 includes a planetary gear train 11, an engine 13, a motor 12 and an output shaft 14. The planetary gear train 11 has a sun gear 111, a planet carrier 112 and a ring gear 113. The planet carrier 112 is provided with a plurality of planetary gears 114. The plurality of planetary gears 114 are movably arranged on the periphery of the sun gear 111 and meshed with the sun gear 111. The ring gear 113 is movably arranged on the periphery of the plurality of planetary gears 114 and meshed with the plurality of planetary gears 114. One of the engine 13 and the motor 12 is power-connected to the ring gear 113, the other of the engine 13 and the motor 12 is power-connected to the sun gear 111, and the output shaft 14 is power-connected to the planet carrier 112.

[0030] At present, the vehicle's drive system plays a vital role in the operation and performance of the entire vehicle. The drive system can effectively convert the energy generated by the vehicle's power source into the rotational power of the wheels, thereby driving the vehicle forward, backward, turning or stopping. Its performance directly affects the vehicle's driving experience and power. The existing vehicle drive system generally only has the function of disconnecting or combining the drive motor and the engine power. The power performance of the entire vehicle is poor, which seriously affects the driving experience.

[0031] like Figure 1 and Figure 4 As shown, specifically, the drive assembly 10 includes a planetary gear train 11 and an input end and an output end that are power-connected to the planetary gear train 11. The input end may be an engine 13 and a motor 12, and the output end may be an output shaft 14. The planetary gear train 11 has a sun gear 111, a planet carrier 112, and a ring gear 113. A planetary gear 114 may be disposed on the planet carrier 112. The planetary gear 114 may be constructed in plurality. The plurality of planetary gears 114 may be disposed on the periphery of the sun gear 111 and meshed therewith. The planetary gear 114 may move on the periphery of the sun gear 111 to achieve power transmission. The ring gear 113 is disposed on the periphery of the plurality of planetary gears 114, and the ring gear 113 may mesh with the plurality of planetary gears 114 to achieve power transmission. The planetary gear 114 may be located between the sun gear 111 and the ring gear 113.

[0032] One of the engine 13 and the motor 12 can be connected to the ring gear 113, the other of the engine 13 and the motor 12 can be connected to the sun gear 111, and the output shaft 14 is connected to the planetary carrier 112. In a specific embodiment, the engine 13 is connected to the ring gear 113, and the motor 12 is connected to the sun gear 111. The output torque provided by the engine 13 can be transmitted to the ring gear 113, and the output torque provided by the motor 12 can be transmitted to the sun gear 111. The sun gear 111 and the ring gear 113 rotate and mesh with the planetary gear 114 to transmit power to the planetary carrier 112, and then transmit it from the planetary carrier 112 to the output shaft 14, thereby completing the power transmission of the motor 12 and the engine 13. By adopting the planetary gear system 11, the torque of the engine 13 and the motor 12 can be superimposed. For example, the output torque of the engine 13 is constant, and the output torque is adjusted by adjusting the output torque of the motor 12 to reduce fuel consumption. Therefore, the above structure can make the whole vehicle more powerful and improve the user's driving experience.

[0033] In short, the drive assembly 10 of the embodiment of the present application has a planetary gear train 11, which has a sun gear 111, a planetary gear 114 movably arranged on the outer periphery of the sun gear 111 and meshing with the sun gear 111, and a ring gear 113 arranged on the outer periphery of the planetary gear 114. The planetary gear 114 is constructed in multiples and is linked through a planetary carrier 112. One of the engine 13 and the motor 12 is connected to the ring gear 113, and the other of the engine 13 and the motor 12 is connected to the sun gear 111. The power output by the engine 13 and the power output by the motor 12 can be transmitted to the planetary carrier 112 through the sun gear 111 and the ring gear 113, and then transmitted to the output shaft 14, thereby achieving the effect of superimposing the torque of the engine 13 and the motor 12, making the whole vehicle more powerful and improving the user's driving experience.

[0034] like Figure 1 As shown, in some embodiments of the present application, the motor 12 has a first input shaft 121, and the drive assembly 10 also includes a first clutch 15. The first clutch 15 can be connected between the first input shaft 121 and the output shaft 14, and the first clutch 15 can selectively engage the first input shaft 121 with the output shaft 14. It can be understood that the first input shaft 121 can be selectively connected to the output shaft 14 through the first clutch 15.

[0035] As some embodiments of the present application, the first clutch 15 can be but is not limited to an electromagnetic clutch, a magnetic powder clutch, a friction clutch, a hydraulic clutch, etc. Of course, the first clutch 15 can also be constructed as other types of clutches. It can be understood that the specific type of the first clutch 15 can be selected according to actual needs, and the present application does not impose any restrictions on this.

[0036] By providing the first clutch 15 and connecting the first clutch 15 between the first input shaft 121 and the output shaft 14, selective connection between the first input shaft 121 and the output shaft 14 can be achieved. In addition, the above arrangement can make the connection between the first input shaft 121 and the output shaft 14 reliable, which is beneficial to improving the working reliability of the drive assembly 10.

[0037] like Figure 1 As shown, in some embodiments of the present application, the engine 13 has a second input shaft 131, and the drive assembly 10 also includes a second clutch 16. The second clutch 16 can be connected between the second input shaft 131 and the ring gear 113, and the second clutch 16 can selectively engage the second input shaft 131 with the ring gear 113. It can be understood that the second input shaft 131 can be selectively connected to the ring gear 113 through the second clutch 16.

[0038] As some embodiments of the present application, the second clutch 16 can be but is not limited to an electromagnetic clutch, a magnetic powder clutch, a friction clutch, a hydraulic clutch, etc. Of course, the second clutch 16 can also be constructed as other types of clutches. It can be understood that the specific type of the second clutch 16 can be selected according to actual needs, and the present application does not impose any restrictions on this.

[0039] By providing the second clutch 16 and connecting the second clutch 16 between the second input shaft 131 and the ring gear 113, selective connection between the second input shaft 131 and the ring gear 113 can be achieved. In addition, the above arrangement can make the connection between the second input shaft 131 and the ring gear 113 reliable, which is beneficial to improving the working reliability of the drive assembly 10.

[0040] In some embodiments of the present application, the drive assembly 10 has an engine direct drive mode. In the engine direct drive mode, the second clutch 16 engages the second input shaft 131 with the ring gear 113. At this time, the motor 12 is not working, and the power of the engine 13 is transmitted to the second clutch 16 through the second input shaft 131, and then transmitted from the second clutch 16 to the ring gear 113. Next, the power is transmitted to the planetary carrier 112 through the ring gear 113, and finally transmitted from the planetary carrier 112 to the output shaft 14, so that the engine 13 directly provides power to the output shaft 14.

[0041] In some embodiments of the present application, the drive assembly 10 has a motor direct drive mode. In the motor direct drive mode, the first clutch 15 engages the first input shaft 121 and the output shaft 14, and the second clutch 16 is in a disconnected state. At this time, the power of the engine 13 is not transmitted, and the power of the motor 12 is directly transmitted to the output shaft 14 through the first input shaft 121. The motor 12 directly drives the output shaft 14, and the speed ratio between the first input shaft 121 and the output shaft 14 is 1.

[0042] In some embodiments of the present application, the drive assembly 10 has a first hybrid drive mode. In the first hybrid drive mode, the first clutch 15 is in a disconnected state, and the second clutch 16 engages the second input shaft 131 with the ring gear 113. At this time, the first input shaft 121 is connected to the sun gear 111 by power, and the second input shaft 131 is connected to the ring gear 113 by power. The power of the motor 12 is transmitted to the sun gear 111 through the first input shaft 121, and the power of the engine 13 is transmitted to the second clutch 16 through the second input shaft 131, and then transmitted from the second clutch 16 to the ring gear 113. The power of the motor 12 and the power of the engine 13 are transmitted to the output shaft 14 through the planetary carrier 112, wherein the motor 12 has a speed regulation mode, and the motor 12 can change the speed of the planetary carrier 112 to the output shaft 14 by adjusting the speed of the first input shaft 121. In the specific embodiment, the engine 13 is at a constant speed, and provides power efficiently while reducing fuel consumption. The motor 12 can change the speed at the sun gear 111 by adjusting the speed of the first input shaft 121. When the speed of the ring gear 113 is constant, the power output from the planetary carrier 112 to the output shaft 14 is changed by changing the speed at the sun gear 111. For example, when the torque required by the input shaft is greater than the torque provided by the engine 13, the motor 12 can increase the speed of the first input shaft 121 to supplement the torque lacking in the engine 13. When the torque required by the input shaft is less than the torque provided by the engine 13, the motor 12 can consume the power of the engine 13 by reducing the speed of the first input shaft 121, thereby reducing the final output torque. The above working mode can reduce fuel consumption and improve fuel economy.

[0043] In some embodiments of the present application, the drive assembly 10 has a second hybrid drive mode. In the second hybrid drive mode, the first clutch 15 engages the first input shaft 121 and the output shaft 14, and the second clutch 16 engages the second input shaft 131 with the ring gear 113. The first input shaft 121 is dynamically connected to the output shaft 14, and the second input shaft 131 is dynamically connected to the ring gear 113. At this time, the power of the motor 12 is transmitted to the first clutch 15 through the first input shaft 121, and then transmitted to the output shaft 14 through the first clutch 15. The power of the engine 13 is transmitted to the second clutch 16 through the second input shaft 131, and then transmitted from the second clutch 16 to the ring gear 113. Then, the power is transmitted to the planetary carrier 112 through the ring gear 113, and finally transmitted from the planetary carrier 112 to the output shaft 14. At this time, the motor 12 and the engine 13 both directly transmit power to the output shaft 14, and the power of the engine 13 and the power of the motor 12 are used as a power source to drive the vehicle.

[0044] like Figure 2 and Figure 3As shown, in some embodiments of the present application, in the axial direction of the output shaft 14, the planetary gear train 11 is located between the first clutch 15 and the second clutch 16, and the output shaft 14 and the first input shaft 121 are on the same axis. The above arrangement can save radial space and facilitate the layout of the vehicle, wherein the motor 12 can be connected to the first clutch 15 by welding or the like, the clutch oil paths of the first clutch 15 and the second clutch 16 can enter through the housing, the second clutch 16 and the second input shaft 131 can be fixedly connected by welding or the like, and the second clutch 16 can be wrapped in the planet carrier 112. In other embodiments of the present application, in the axial direction of the output shaft 14, the first clutch 15 is located between the planetary gear train 11 and the second clutch 16.
