[0045] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0046] In the present disclosure, unless otherwise stated, directional words such as "inside" and "outside" refer to the inside and outside relative to the contour of the corresponding component itself. The terms "first" and "second" used in the present disclosure are to distinguish one element from another element and do not have order and importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0047] According to a specific embodiment of the present disclosure, a hybrid power system is provided, referring to Figures 1 to 15 As shown, the hybrid power system may include a first drive module 10 , and the first drive module 10 may include an engine 1 , a first motor 2 , a planetary gear 3 and a first clutch 41 .
[0048] Among them, the planetary row 3 can be coupled between the first motor 2, the engine 1 and the power splitting mechanism 5, and the power splitting mechanism 5 is arranged on the front drive axle and / or the rear drive axle. Specifically, the planetary row 3 may include a sun gear 31, a ring gear 32, a planetary gear 33 and a planet carrier 34, the rotating shaft of the first motor 2 may be coaxially fixedly connected with the sun gear 31, the ring gear 32 may be coaxially arranged with the sun gear 31, a plurality of planetary gears 33 may be meshed between the sun gear 31 and the ring gear 32, the planet carrier 34 may be connected with a plurality of planetary gears 33, one of the ring gear 32 and the planet carrier 34 may be coaxially fixedly connected with the output shaft of the engine 1, so that the engine 1 inputs torque to the planetary row 3, and the other of the ring gear 32 and the planet carrier 34 may be transmission-connected with the power splitting mechanism 5 to transfer the torque output by the engine 1 to the power splitting mechanism 5. In the specific embodiment of the present disclosure, the power splitting mechanism 5 may be set as a differential, a transfer case or other power output and splitting mechanism as needed.
[0049] The first clutch 41 may be disposed between the sun gear 31 and the drive axle case 6 , and may have an engaged state in which the sun gear 31 and the drive axle case 6 are relatively locked, and a disengaged state in which the sun gear 31 and the drive axle case 6 are released.
[0050] The hybrid system can have at least the following gears:
[0051] When the first clutch 41 is in the engaged state, the sun gear 31 cannot rotate, that is, the planetary gear 3 cannot transmit torque to the first motor 2 , and the hybrid system can have a direct drive gear that transmits all the torque output by the engine 1 to the power split mechanism 5 .
[0052] When the first clutch 41 is in a disengaged state and the first motor 2 is in a power generation mode, the hybrid system can have a power diversion gear that diverts the torque output by the engine 1 to the power diversion mechanism 5 and the first motor 2. The first motor 2 can use the torque transmitted by the sun gear 31 for power generation. In the power diversion gear, the ratio of the torque diverted to the power diversion mechanism 5 and the first motor 2 through the planetary gear 3 is adjustable to realize the stepless speed regulation function in the power diversion gear.
[0053] When the first clutch 41 is in a disengaged state and the first motor 2 is in a driving mode, the hybrid system may have a hybrid gear (M1+engine dual-engine hybrid) in which the engine 1 and the first motor 2 simultaneously input torque to the planetary gear 3 .

[0055] When the first clutch 41 is in a disengaged state and the vehicle brakes suddenly, the hybrid system may have a power recovery gear (M1 feedback). At this time, the power of the wheels may be transmitted to the first motor 2 via the planetary gear 3 and recovered to the battery through the first motor 2.
[0056] Through the above technical solution, in the hybrid power system provided by the present disclosure, the engine 1, the first motor 2 and the power splitting mechanism 5 are coupled through a planetary gear 3, the first motor 2 is coaxially fixedly connected with the sun gear 31 of the planetary gear 3, and a first clutch 41 is arranged between the sun gear 31 and the drive axle housing 6. By switching the first clutch 41 between the engaged state and the disengaged state, and by switching the first motor 2 between the driving mode and the power generation mode, the hybrid power system can have at least a plurality of operating gears such as a direct drive gear, a power splitting gear, a hybrid gear, a parking power generation gear and a power recovery gear. Therefore, the hybrid power system provided by the present disclosure can realize multi-gear operation while having a simple structure.

The first input gear 71 is meshed with the ring gear 32 or the planetary carrier 34 of the planetary gear 3, and the first output gear 72 is meshed with the power splitting mechanism gear 51.
[0058] In addition, reference Figures 1 to 15As shown, the hybrid system may further include a second drive module 20, and the second drive module 20 may include a second motor 8. The rotating shaft of the second motor 8 may be drivingly connected to the input shaft of the power split mechanism 5.

[0060] Among them, as an option, the planetary gear set 3 and the second motor 8 are respectively drivingly connected to the power split mechanism 5 through a first reduction mechanism 7 and a second reduction mechanism 9. Referring to Figure 1 , Figure 4 , Figure 7 , Figure 10 and Figure 13 as shown, the second reduction mechanism 9 includes a second input gear 91, a second transmission gear 92, and a second output gear 93. Among them, the second input gear 91 may be fixedly connected to the rotating shaft of the second motor 8 coaxially, the second transmission gear 92 is fixedly connected to the second output gear 93 coaxially, the second transmission gear 92 meshes with the second input gear 91, and the second output gear 93 meshes with the power split mechanism gear 51.
[0061] As another option, both the planetary gear set 3 and the second motor 8 are drivingly connected to the same power split mechanism 5 through the first reduction mechanism. Referring to Figure 2 , Figure 5 , Figure 8 , Figure 11 and Figure 14 as shown, both the planetary gear set 3 and the second motor 8 are drivingly connected to the power split mechanism 5 by meshing with the first input gear 71.
