[0043] The power motor 5 is connected to a motor input gear 51 , and the motor input gear 51 is configured to be selectively power-connected to the first driving gear 21 or the second driving gear 31 .

[0044] Specifically, by connecting the power motor 5 to the motor input gear 51, the power of the power motor 5 can be transmitted outward through the motor input gear 51. At the same time, the motor input gear 51 can be connected to the first driving gear 21 or the second driving gear 31. When the motor input gear 51 is connected to the first driving gear 21, the power of the power motor 5 can be transmitted to the first driving gear 21 through the motor input gear 51, and transmitted to the output shaft 4 through the cooperation between the first driving gear 21 and the first driven gear 41. When the motor input gear 51 is connected to the second driving gear 31, the power of the power motor 5 can be transmitted to the second driving gear 31 through the motor input gear 51, and transmitted to the output shaft 4 through the cooperation between the second driving gear 31 and the second driven gear 42, and then transmitted to the first wheel axle 6 to drive the vehicle to run.

[0045] In some embodiments, the power drive system 100 further includes an intermediate shaft 7 , which is provided with an intermediate input gear 71 and an intermediate output gear 72 . The intermediate input gear 71 meshes with the motor input gear 51 , and the intermediate output gear 72 meshes with the first driving gear 21 or the second driving gear 31 .

[0046] Specifically, the intermediate shaft 7 is used to provide an installation position for the intermediate input gear 71 and the intermediate output gear 72, that is, the intermediate input gear 71 and the intermediate output gear 72 are both arranged on the outside of the intermediate shaft 7, and the intermediate input gear 71 is meshed with the motor input gear 51, so that the power of the power motor 5 can be transmitted to the intermediate shaft 7 through the cooperation between the motor input gear 51 and the intermediate input gear 71, and the intermediate output gear 72 can be meshed with the first driving gear 21 or the second driving gear 31, that is, the intermediate output gear 72 is meshed with the first driving gear 21 to transmit the power of the power motor 5 to the first driving gear 21, or the intermediate output gear 72 is meshed with the second driving gear 31 to transmit the power of the power motor 5 to the second driving gear 31, and then can be transmitted to the output shaft 4 to drive the vehicle to run.

[0048] Specifically, two intermediate output gears 72 are provided, and the two intermediate output gears 72 are respectively meshed with the first driving gear 21 and the second driving gear 31, so that one of the intermediate output gears 72 is meshed with the first driving gear 21, and the power of the power motor 5 is transmitted to the first driving gear 21 through the intermediate output gear 72, and the other intermediate output gear 72 is meshed with the second driving gear 31, and the power of the power motor 5 is transmitted to the second driving gear 31 through the intermediate output gear 72, and then can be transmitted to the output shaft 4 to drive the vehicle to run. At the same time, the two intermediate output gears 72 are respectively empty sleeved on the intermediate shaft 7, that is, the power on the intermediate shaft 7 cannot be directly transmitted to the two intermediate output gears 72.

[0049] Furthermore, a first synchronizer 13 is provided on the intermediate shaft 7, so that the first synchronizer 13 can selectively connect one of the intermediate output gears 72 with the intermediate shaft 7, that is, the power of the intermediate shaft 7 can be transmitted to any intermediate output gear 72 through the first synchronizer 13. When the first synchronizer 13 connects the intermediate output gear 72 meshing with the first driving gear 21 with the intermediate shaft 7, the power of the power motor 5 can be transmitted to the intermediate output gear 72 and transmitted to the output shaft 4 through the first driving gear 21.

[0050] In such Figure 1-Figure 2 In the illustrated embodiment, the intermediate shaft 7 is extended in the longitudinal direction of the vehicle, so that the two intermediate output gears 72 can be spaced apart in the front-rear direction of the vehicle, so that the intermediate output gear 72 close to the first driving gear 21 can be meshed with the first driving gear 21, and the intermediate output gear 72 close to the second driving gear 31 can be meshed with the second driving gear 31, so as to facilitate the transmission of power from the power motor 5 through the intermediate output gear 72.

[0051] In some embodiments, the first driving gear 21 and the first driven gear 41 are both in multiple groups and correspond one to one. Each group of first driven gears 41 has two and are both hollowly sleeved outside the output shaft 4. The two first driven gears 41 in each group are selectively connected to the output shaft 4 through the second synchronizer 14.

[0052] Specifically, the first driving gear 21 is meshed with the first driven gear 41, and the power of the first input shaft 2 can be transmitted from the first driving gear 21 to the first driven gear 41. The first driving gear 21 and the first driven gear 41 are both arranged in multiple groups, so that the power of the engine 1 or the power motor 5 can be transmitted through the multiple groups of first driving gears 21 and the multiple groups of first driven gears 41, and the multiple groups of first driving gears 21 and the multiple groups of first driven gears 41 are matched one by one, that is, for each first driving gear 21, a first driven gear 41 is arranged to match it, which can improve the reliability of power transmission using the first driving gear 21 and the first driven gear 41.

[0053] Furthermore, there are two first driven gears 41 in each group and both are hollowly mounted outside the output shaft 4. Even if the power on the first driven gears 41 cannot be directly transmitted to the output shaft 4, and the two first driven gears 41 in each group can be selectively connected to the output shaft 4 through the second synchronizer 14, any one of the first driven gears 41 can be connected to the output shaft 4 through the second synchronizer 14, so that the power on the first driven gears 41 can be transmitted to the output shaft 4, and then transmitted to the first axle 6 to drive the vehicle to run, and by connecting different first driven gears 41 to the output shaft 4, the gear position of the vehicle can be adjusted.

[0054] In such Figure 1-Figure 2 In the illustrated embodiment, four first driving gears 21 and two groups of first driven gears 41 are provided, and the four first driving gears 21 correspond to the two groups of first driven gears 41 one by one. At the same time, two second synchronizers 14 are provided, and the two groups of first driven gears 41 can be controlled simultaneously by the two second synchronizers 14, and the first driven gear 41 connected to the output shaft 4 with power is selected, that is, the gear position of the vehicle is adjusted.

[0055] And / or, the second driving gear 31 and the second driven gear 42 are both in multiple groups and correspond one to one, each group of second driven gears 42 has two and are both hollowly sleeved outside the output shaft 4, and the two second driven gears 42 in each group are selectively connected to the output shaft 4 through the third synchronizer 15.

[0056] Specifically, the second driving gear 31 is meshed with the second driven gear 42, and the power of the second input shaft 3 can be transmitted from the second driving gear 31 to the second driven gear 42. The second driving gear 31 and the second driven gear 42 are both arranged in multiple groups, so that the power of the engine 1 or the power motor 5 can be transmitted through the multiple groups of second driving gears 31 and the multiple groups of second driven gears 42, and the multiple groups of second driving gears 31 and the multiple groups of second driven gears 42 are matched one by one, that is, for each second driving gear 31, a second driven gear 42 is provided to cooperate with it, which can improve the reliability of power transmission using the second driving gear 31 and the second driven gear 42.

[0057] Furthermore, each group of second driven gears 42 is two and both are hollowly mounted outside the output shaft 4. Even if the power on the second driven gears 42 cannot be directly transmitted to the output shaft 4, and the two second driven gears 42 in each group can be selectively connected to the output shaft 4 through the third synchronizer 15, any one of the second driven gears 42 can be connected to the output shaft 4 through the third synchronizer 15, so that the power on the second driven gears 42 can be transmitted to the output shaft 4, and then transmitted to the first axle 6 to drive the vehicle to run, and by connecting different second driven gears 42 to the output shaft 4, the gear position of the vehicle can be adjusted.

[0058] In such Figure 1-Figure 2 In the illustrated embodiment, four second driving gears 31 and two groups of second driven gears 42 are provided, and the four second driving gears 31 correspond to the two groups of second driven gears 42 one by one. At the same time, two third synchronizers 15 are provided, and the two groups of second driven gears 42 can be controlled simultaneously by the two third synchronizers 15, so that the second driven gear 42 connected to the output shaft 4 is selected, that is, the gear position of the vehicle is adjusted.

[0059] Thus, two sets of first driven gears 41 and two sets of second driven gears 42 can be controlled simultaneously by two second synchronizers 14 and two third synchronizers 15, and then the first driven gears 41 and the second driven gears 42 connected to the output shaft 4 can be selected, so that eight-speed adjustment of the vehicle can be realized.

[0060] In some embodiments, the first input shaft 2 and the second input shaft 3 both extend in the longitudinal direction of the vehicle, and the power motor 5 and the output shaft 4 are respectively located on both sides of the first input shaft 2 or the second output shaft 4 in the transverse direction of the vehicle.

[0061] Specifically, the first input shaft 2 and the second input shaft 3 can both be used to transmit the power of the engine 1 or the power motor 5 outward. The first input shaft 2 and the second input shaft 3 are arranged to extend along the longitudinal direction of the vehicle, which can increase the setting length of the first input shaft 2 and the second input shaft 3, and facilitate the first input shaft 2 and the second input shaft 3 to be respectively connected to the multiple groups of first driving gears 21 and the multiple groups of second driving gears 31 by power, so as to realize multi-gear adjustment of the vehicle. At the same time, the power motor 5 and the output shaft 4 are respectively arranged on both sides of the first input shaft 2 and the second input shaft 3, so that the power motor 5 and the output shaft 4 can respectively use the space in the left and right directions of the first input shaft 2 and the second input shaft 3, so that the arrangement of the power motor 5 and the output shaft 4 is relatively dispersed, and will not be installed too compactly, and the space occupied by the power drive system 100 in the longitudinal direction of the vehicle can be reduced, thereby reducing the overall longitudinal size of the vehicle, reducing the development difficulty and development cost of the clutch, and improving the driving experience.

[0062] In some embodiments, the power drive system 100 also includes a battery 8 and a second axle 9, the battery 8 is used to be electrically connected to the power motor 5, the second axle 9 and the first axle 6 are spaced apart and distributed along the longitudinal direction of the vehicle, and the battery 8 is located between the first axle 6 and the second axle 9.

[0063] Specifically, the battery 8 is electrically connected to the power motor 5, and the battery 8 can be used to provide electrical energy to the power motor 5. The second axle 9 is configured to extend along the lateral direction of the vehicle, and is used to be connected to the left rear wheel 103 and the right rear wheel 104 of the vehicle at the same time, or to be connected to the left front wheel 101 and the right front wheel 102 of the vehicle at the same time, that is, the present application can be applicable to four-wheel vehicles. The second axle 9 and the first axle 6 are spaced apart and distributed along the longitudinal direction of the vehicle, so as to avoid interference between the two wheels connected to the second axle 9 and the two wheels connected to the first axle 6, which may cause the vehicle to be unable to run, and the stability of the vehicle may be improved. In addition, the battery 8 is disposed between the first axle 6 and the second axle 9, so that the battery 8 can be disposed near the center of the vehicle, so that the center of gravity of the vehicle can be closer to the center of the vehicle to improve the driving stability of the vehicle, and the distance between the battery 8 and the power motor 5 can be reduced, so as to facilitate the battery 8 to provide electrical energy to the power motor 5.

[0064] In such Figure 1-Figure 2 In the illustrated embodiment, the first axle 6 is located at the rear side of the vehicle, that is, the first axle 6 is connected to both the left rear wheel 103 and the right rear wheel 104 of the vehicle, and the second axle 9 is located at the front side of the vehicle, that is, the second axle 9 is connected to both the left front wheel 101 and the right front wheel 102 of the vehicle, and the first axle 6 is dynamically connected to the output shaft 4, that is, the present application can be applied to rear-wheel drive vehicles.

[0065] In some embodiments, the engine 1 is located between the first axle 6 and the second axle 9 , and the output shaft 4 and the power motor 5 are located on a side of the first axle 6 facing away from the second axle 9 .

[0066] Specifically, Figure 1 As shown, the engine 1 is arranged between the first axle 6 and the second axle 9, so that the center of gravity of the vehicle can be closer to the center of the vehicle, which can improve the driving stability of the vehicle. At the same time, the output shaft 4 and the power motor 5 are arranged on the side of the first axle 6 away from the second axle 9, that is, the output shaft 4 and the power motor 5 are both arranged on the rear side of the first axle 6, and the output shaft 4 and the power motor 5 are respectively arranged on both sides of the first input shaft 2 and the second input shaft 3, which can reduce the space occupied by the power drive system 100 in the longitudinal direction of the vehicle, thereby reducing the overall longitudinal size of the vehicle, reducing the difficulty and cost of developing the clutch, and improving the driving experience.

[0067] In some embodiments, the output shaft 4 and the power motor 5 are located between the first axle 6 and the second axle 9 , and the engine 1 is located on a side of the first axle 6 facing away from the second axle 9 .

[0068] Specifically, Figure 2As shown, the output shaft 4 and the power motor 5 are both arranged between the first axle 6 and the second axle 9, that is, the output shaft 4 and the power motor 5 are both arranged at a position close to the center of the vehicle, and the output shaft 4 and the power motor 5 are respectively arranged on both sides of the first input shaft 2 and the second input shaft 3, which can reduce the space occupied by the power drive system 100 in the longitudinal direction of the vehicle, thereby reducing the overall longitudinal size of the vehicle, reducing the development difficulty and development cost of the clutch, and improving the driving experience. At the same time, the engine 1 is arranged on the side of the first axle 6 away from the second axle 9, that is, the engine 1 is arranged on the rear side of the first axle 6, which can more reasonably utilize the space on the vehicle and make the overall structural design more reasonable.

[0069] And, it should be noted that if Figure 1-Figure 2 As shown, a transmission shaft 44 is also provided between the output shaft 4 and the first wheel axle 6, a transmission gear 45 is sleeved on the transmission shaft 44, and the transmission shaft 44 is connected to the first wheel axle 6 through a main reducer 46. At the same time, an output gear 43 is also sleeved on the output shaft 4, and the output gear 43 is meshed with the transmission gear 45. The power of the engine 1 or the power motor 5 can be transmitted from the output shaft 4 through the transmission shaft 44 and the main reducer 46 to the first wheel axle 6 through the cooperation between the output gear 43 and the transmission gear 45.

[0070] In addition, this application can realize multiple working modes of the vehicle, as follows:

[0071] When the engine 1 is disconnected from the first input shaft 2 and the second input shaft 3, one of the intermediate output gears 72 can be connected to the intermediate shaft 7 through the first synchronizer 13 to transmit the power of the power motor 5 to the output shaft 4, thereby enabling the vehicle to run in pure electric mode.

[0072] When the battery 8 is low in power or in certain specific operating conditions, such as high-speed cruising, the power motor 5 does not work, and only the engine 1 works to drive the left rear wheel 103 and the right rear wheel 104 to rotate, thereby realizing the operation of the vehicle in pure internal combustion engine mode.

[0073] When the engine 1 is connected to the first input shaft 2 and the first synchronizer 13 is connected to the intermediate output gear 72 close to the first driving gear 21, or when the engine 1 is connected to the second input shaft 3 and the first synchronizer 13 is connected to the intermediate output gear 72 close to the second driving gear 31, the engine 1 and the power motor 5 can jointly drive the first wheel axle 6 to realize the operation of the vehicle in hybrid mode.

[0074] When the second synchronizer 14 and the third synchronizer 15 are both disconnected, the engine 1 is connected to the first input shaft 2 or the second input shaft 3, and the first synchronizer 13 is engaged, the engine 1 can generate electricity for the power motor 5 and store it in the battery 8, thereby realizing the vehicle's idle power generation mode; the engine 1 uses part of the power to drive the wheels to rotate, and the other part of the power is used to generate electricity for the power motor 5 and store it in the battery 8, thereby realizing the vehicle's driving power generation mode; the wheel torque can be transmitted to the power motor 5 for braking energy recovery, thereby realizing the vehicle's braking energy recovery.

[0075] The utility model also provides a vehicle.

[0076] According to the vehicle of the embodiment of the utility model, a power drive system 100 of any one of the above items is provided. By simultaneously arranging the engine 1 and the power motor 5 on the vehicle, the present application can be applied to a hybrid vehicle model. At the same time, the engine 1 or the power motor 5 is selectively connected to the first input shaft 2 or the second input shaft 3 by power, and the first input shaft 2 or the second input shaft 3 is selectively connected to the output shaft 4 by power, and the output shaft 4 is connected to the first wheel shaft 6 by power. The power generated by the engine 1 or the power motor 5 can be transmitted from the first input shaft 2 or the second input shaft 3 to the first wheel shaft 6 through the output shaft 4 to drive the two wheels connected to the first wheel shaft 6 to rotate, thereby driving the vehicle to run, meeting user needs, and, through reasonable arrangement, the space occupied by the power drive system 100 in the longitudinal direction of the vehicle can be reduced, thereby reducing the overall longitudinal size of the vehicle, and reducing the difficulty and cost of developing the clutch, thereby improving the driving experience.
