The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0028] Reference is made below to Figure 1 a drive assembly 100 of a vehicle according to an embodiment of the present application.

[0029] As Figure 1 shown, the drive assembly 100 according to an embodiment of the present application includes an engine 10, a transmission shaft 1, a planetary gear set 20, a drive motor 30, and an output shaft 2.

[0030] The engine 10 is in driving connection with the transmission shaft 1; the ring gear 23 of the planetary gear set 20 is selectively coupled with the transmission shaft 1, the sun gear 21 of the planetary gear set 20 is in driving connection with the drive motor 30, the carrier 22 of the planetary gear set 20 is in driving connection with the transmission shaft 1; and the output shaft 2 is selectively coupled with at least one of the sun gear 21 and the ring gear 23.

[0031] The engine 10 is connected to the drive shaft 1 via a transmission connection.

The ring gear 23 of the planetary gear set 20 selectively engages with the drive shaft 1; that is, the ring gear 23 may or may not engage with the drive shaft 1.

[0032] The sun gear 21 of the planetary gear set 20 is connected to the drive motor 30. The sun gear 21 and the drive motor 30 can be connected by a spline connection, a gear pair connection, etc. As some embodiments of this application, the sun gear 21 and the drive motor 30 are connected by a gear pair connection.

[0033] The planet carrier 22 of the planetary set 20 is connected to the drive shaft 1. The planet carrier 22 and the drive shaft 1 can be connected by, but are not limited to, spline connection, gear pair connection, etc. As some embodiments of this application, the planet carrier 22 and the drive shaft 1 are connected by spline connection.

[0034] The output shaft 2 is selectively engaged with at least one of the sun gear 21 and the ring gear 23. That is, the output shaft 2 may be engaged with the sun gear 21, or the output shaft 2 may be engaged with the ring gear 23, or the output shaft 2 may be engaged with both the sun gear 21 and the ring gear 23 simultaneously, or the output shaft 2 may be engaged with neither the sun gear 21 nor the ring gear 23.

[0035] As some embodiments of this application, such as Figure 1 As shown, the engine 10 has a first input shaft 11, which is connected to the planet carrier 22 of the planetary gear 20. The drive motor 30 has a second input shaft 31, which is connected to the transmission shaft 1.

[0036] The drive assembly 100 can have multiple operating modes, including but not limited to engine 10 direct drive mode, hybrid mode, power split mode, pure electric mode, and generator mode. The specific operating states of the drive assembly 100 under these multiple operating modes are described in detail below.

[0037] In the direct drive mode of engine 10, the drive assembly 100 is driven by engine 10. The direct drive mode of engine 10 can be divided into direct drive first gear mode and direct drive second gear mode.

[0038] Direct drive first gear mode, in the direct drive first gear mode, the ring gear 23 is combined with the transmission shaft 1 to lock the planetary carrier 22 and the ring gear 23, the output shaft 2 is combined with the ring gear 23, the power of the engine 10 is transmitted to the ring gear 23 through the transmission shaft 1, and then transmitted to the output shaft 2 to drive the vehicle to run, the mode has a large speed ratio, and is suitable for medium and low vehicle speed and large wheel end torque.

[0039] Direct drive second gear mode, in the direct drive second gear mode, the ring gear 23 is combined with the transmission shaft 1 to lock the planetary carrier 22 and the ring gear 23, the output shaft 2 is combined with the sun gear 21, the power of the engine 10 is transmitted to the ring gear 23 through the transmission shaft 1, and then transmitted to the sun gear 21, and then transmitted to the output shaft 2 through the sun gear 21 to drive the vehicle to run, the mode has a small speed ratio, and is suitable for medium and high vehicle speed and small wheel end torque.

[0040] Hybrid mode, in the hybrid mode, the engine 10 and the drive motor 30 can drive the output shaft 2 to drive the vehicle, and the hybrid mode can be divided into a first hybrid mode and a second hybrid mode.

[0041] First hybrid mode, in the first hybrid mode, the ring gear 23 is not combined with the transmission shaft 1, the output shaft 2 is not combined with the sun gear 21, the output shaft 2 is combined with the ring gear 23, the power of the drive motor 30 is transmitted to the ring gear 23 through the sun gear 21, the power of the engine 10 is transmitted to the ring gear 23 through the planetary gear set 20, and the power of the drive motor 30 and the power of the engine 10 are coupled in the ring gear 23 and then transmitted to the output shaft 2 to drive the vehicle to run.

[0042] It should be noted that in this process, the engine 10 and the drive motor 30 first actively reduce the torque, the drive motor 30 can drive the engine 10 to adjust the speed, so that the speed of the output shaft 2 and the speed of the transmission shaft 1 are within a certain speed range, and then the output shaft 2 is combined with the ring gear 23.

[0043] As some embodiments of the present application, the vehicle switching from engine direct drive mode to the first hybrid mode can make the vehicle obtain explosive torque, so that the vehicle obtains a larger acceleration. For example, the vehicle has a vehicle controller, a drive assembly controller, an engine controller and a drive motor controller. When the vehicle switches from the direct drive second gear mode to the first hybrid mode, the engine controller and the drive motor controller can receive the torque increasing instruction of the vehicle controller. The engine controller and the drive motor controller will first issue a torque decreasing instruction to make the engine 10 and the drive motor 30 actively reduce the torque. The drive assembly controller controls the output shaft 2 to be disconnected from the sun gear 21. Then the drive motor 30 can drive the engine 10 to adjust the speed, so that the speed of the output shaft 2 and the speed of the transmission shaft 1 are within a certain speed range. Then the drive assembly controller controls the output shaft 2 to be combined with the ring gear 23. Then the engine controller and the drive motor controller simultaneously issue a torque increasing instruction to make the engine 10 and the drive motor 30 simultaneously explode torque to accelerate the vehicle.

[0044] The second hybrid mode, in the second hybrid mode, the output shaft 2 is combined with the sun gear 21, and then the ring gear 23 is in a sliding state with the transmission shaft 1 (between combined and not combined), and then the output shaft 2 is combined with the ring gear 23, and then the ring gear 23 is disconnected from the transmission shaft 1. The power of the drive motor 30 is transmitted to the output shaft 2 through the sun gear 21. The power of the engine 10 is transmitted to the ring gear 23 through the carrier 22, and then transmitted to the output shaft 2. The power of the drive motor 30 and the engine 10 is coupled in the output shaft 2 to drive the vehicle together.

[0045] It should be noted that in this process, after the output shaft 2 is combined with the sun gear 21, the drive motor 30 continuously outputs torque, the ring gear 23 is in a sliding state with the transmission shaft 1, and the engine 10 increases the speed to make the speed of the output shaft 2 and the speed of the transmission shaft 1 within a certain speed range. When the output shaft 2 is completely combined with the ring gear 23, in other words, when the output shaft 2 is drivingly connected to the transmission shaft 1 through the ring gear 23, the ring gear 23 is disconnected from the transmission shaft 1.

[0046] As some embodiments of the present application, the vehicle switching from the engine 10 direct drive mode to the second hybrid mode can make the vehicle obtain explosive torque, so that the vehicle obtains a larger acceleration. For example, the vehicle has a vehicle controller, a drive assembly controller, an engine controller and a drive motor controller. When the vehicle switches from the direct drive second gear mode to the second hybrid mode, the drive assembly controller controls the output shaft 2 to combine with the sun gear 21, the drive motor controller issues a torque increasing instruction to make the drive motor 30 continuously supplement torque, the power of the drive motor 30 is transmitted to the output shaft 2 through the sun gear 21, the drive assembly controller can control the ring gear 23 and the transmission shaft 1 to be in a sliding state, the engine 10 controller controls the engine 10 to speed up, so that the output shaft 2 and the transmission shaft 1 reach a certain speed range, the drive assembly controller controls the output shaft 2 to combine with the ring gear 23, and then the drive assembly controller controls the ring gear 23 to be disconnected with the transmission shaft 1. At this time, the torque of the engine 10 is increased, the engine controller and the drive motor controller simultaneously issue a torque increasing instruction to make the engine 10 and the drive motor 30 simultaneously explode torque, so as to accelerate the vehicle. Such arrangement can make the drive motor 30 continuously supplement torque during mode switching, can reduce the risk of large range and large torque drop, reduce or even avoid the phenomenon of power interruption, and the structure is simple, reasonable and fast during mode switching.

[0047] Power split mode, in the power split mode, the engine 10 can drive the drive motor 30 to generate power, the output shaft 2 is disconnected with the sun gear 21, the ring gear 23 is disconnected with the transmission shaft 1, the output shaft 2 is combined with the ring gear 23, part of the power of the engine 10 is transmitted to the sun gear 21 through the carrier 22, and then drives the drive motor 30 to generate power, and the other part is transmitted to the output shaft 2 through the ring gear 23 to drive the vehicle to run.

[0048] Pure electric mode, in the pure electric mode, the engine 10 does not work, the drive motor 30 drives the vehicle to run, the ring gear 23 is disconnected with the transmission shaft 1, the output shaft 2 is combined with the sun gear 21, the output shaft 2 is disconnected with the ring gear 23, and the power of the drive motor 30 is transmitted to the output shaft 2 through the sun gear 21 to drive the vehicle to run.

[0049] Power generation mode, in the power generation mode, the engine 10 drives the drive motor 30 to generate power, the ring gear 23 is combined with the transmission shaft 1, the output shaft 2 is disconnected with the sun gear 21, and the output shaft 2 is disconnected with the ring gear 23. The power of the engine 10 is transmitted to the sun gear 21 through the carrier 22, and then transmitted to the drive motor 30 through the sun gear 21 to drive the drive motor 30 to generate power.

[0050] It should be noted that the above description of various working modes is only an exemplary description, and does not represent that the driving assembly 100 proposed in the present application is limited to the above working modes, nor does it limit the driving assembly 100 proposed in the present application through the above working modes.

[0051] Therefore, the driving assembly 100 of the present application has simple and reasonable structure, can realize multiple working modes, and the mode switching of the driving assembly 100 of the present application is relatively smooth and weak in jerk, which can significantly improve the acceleration performance of the vehicle and is beneficial to improve the driving experience.

[0052] Moreover, in the driving assembly 100 of the present application, the lower speed ratio mode switching from the engine 10 direct drive mode to the larger speed ratio mode of the hybrid mode can be realized, and the simultaneous large torque explosion of the engine 10 and the driving motor 30 can make the vehicle obtain a good acceleration, the mode switching time is short, the jerk is weak, and it is beneficial to improve the driving feeling.

[0053] In some embodiments of the present application, as shown in Figure 1 The driving assembly 100 of the vehicle further comprises a first coupling device 40 and a coupling member 41, the first coupling device 40 is in transmission connection with the transmission shaft 1, the coupling member 41 is in transmission connection with the ring gear 23, and the first coupling device 40 is selectively combined with the coupling member 41 to selectively combine the ring gear 23 with the transmission shaft 1.

[0056] The first coupling device 40 is selectively combined with the coupling member 41 to selectively combine the ring gear 23 with the transmission shaft 1, specifically, the combination of the first coupling device 40 with the coupling member 41 can combine the ring gear 23 with the transmission shaft 1, and the disconnection of the first coupling device 40 with the coupling member 41 can disconnect the ring gear 23 from the transmission shaft 1.

[0057] By making the driving assembly 100 of the vehicle further include the first coupler 40 and the coupling member 41, the transmission shaft 1 can be selectively in transmission connection with the ring gear 23, so that the driving assembly 100 can realize multiple working modes, and the reliability is better, in addition, by making the ring gear 23 and the coupling member 41 be integrally arranged, the driving assembly 100 can be reasonable and simple in structure, small in occupied space, high in integration degree, and reliable in performance.

[0061] By making the coupling member 41 and the engine 10 be arranged on the two sides of the first coupler 40 along the axial direction of the transmission shaft 1 (that is, the X direction shown in Figure 1 the driving assembly 100 can be reasonable and simple in structure, small in occupied space, and by making the coupling member 41 have a first coupling part 42 on the side facing the first coupler 40, the first coupler 40 can be combined with the coupling member 41, and the driving assembly 100 can be flexibly switched between working modes.
