When the engine 1 is connected with the first input shaft 2, the power generated by itself can be transmitted to the first input shaft 2 and transmitted outwardly through the first input shaft 2. When the engine 1 is connected with the second input shaft 3, the power generated by itself can be transmitted to the second input shaft 3 and transmitted outwardly through the second input shaft 3. At the same time, the first input shaft 2 can be connected or disconnected with the output shaft 4. When the first input shaft 2 is connected with the output shaft 4, the power generated by itself can be transmitted to the second input shaft 3 and transmitted outwardly through the second input shaft 3. When connected, power can be transmitted from the first input shaft 2 to the output shaft 4, and the second input shaft 3 can also be connected to or disconnected from the output shaft 4. When the second input shaft 3 is connected to the output shaft 4, power can be transmitted from the second input shaft 3 to the output shaft 4. In addition, the first input shaft 2 is sleeved outside the second input shaft 3, so that the first input shaft 2 and the second input shaft 3 can be set at the same position, which is convenient for connecting the first input shaft 2 and the second input shaft 3 to the engine 1 from the same position, so that the engine 1 can transmit the power generated by itself to the outside through the first input shaft 2 or the second input shaft 3.

[0034] Furthermore, when the first input shaft 2 is simultaneously connected to the engine 1 and the output shaft 4, the power generated by the engine 1 can be transmitted from the first input shaft 2 to the output shaft 4, and the power can be output through the output shaft 4; when the second input shaft 3 is simultaneously connected to the engine 1 and the output shaft 4, the power generated by the engine 1 can be transmitted from the second input shaft 3 to the output shaft 4, and the power can be output through the output shaft 4.

[0036] The output shaft 4 is connected to the first wheel shaft 6 in power, and the first motor 5 is selectively connected to the output shaft 4 in power.

[0037] Specifically, the first axle 6 is configured to extend in the lateral direction of the vehicle, and is used to be connected to the left front wheel 101 and the right front wheel 102 of the vehicle at the same time, or to be connected to the left rear wheel 103 and the right rear wheel 104 of the vehicle at the same time, and the output shaft 4 is connected to the first axle 6 by power, so that power can be transmitted from the output shaft 4 to the first axle 6, so as to simultaneously drive the two wheels connected to the first axle 6 to rotate, so that the vehicle can be operated, and a first motor 5 is also provided in the power drive system 100, and the first motor 5 is used to convert electrical energy into mechanical energy to provide power for the vehicle and drive the vehicle to operate, that is, the present application can be applicable to electric vehicles, that is, the present application can be applicable to hybrid vehicles, and the first motor 5 can be connected to or disconnected from the output shaft 4 by power. When the first motor 5 is connected to the output shaft 4 by power, the power generated by itself can be transmitted to the output shaft 4, and then to the first axle 6, so as to drive the two wheels connected to the first axle 6 to rotate, so that the vehicle can be operated.

[0038] The second axle 9 is spaced apart from the first axle 6 in the longitudinal direction of the vehicle, and the second motor 16 is selectively power-connected to the second axle 9 .

[0039] Specifically, the second axle 9 is configured to extend in the transverse 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, and the second axle 9 and the first axle 6 are distributed in the longitudinal direction of the vehicle at intervals, 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 causes the vehicle to be unable to run, and can improve the stability of the vehicle, and a second motor 16 is also provided in the power drive system 100, and the second motor 16 is used to convert electrical energy into mechanical energy to provide power for the vehicle and drive the vehicle to run, and the second motor 16 can be connected to or disconnected from the second axle 9 by power. When the second motor 16 is connected to the second axle 9 by power, the power generated by itself can be transmitted to the second axle 9, and the two wheels connected to the second axle 9 can be driven to rotate, so that the vehicle can run.

[0040] Among them, it should be noted that a reduction box 17 is arranged between the second motor 16 and the second axle 9, that is, the second motor 16 and the second axle 9 can be selectively connected through the reduction box 17, and the first axle 6 is connected to the output shaft 4 by power, that is, the power of the engine 1 or the first motor 5 can be transmitted to the first axle 6 through the output shaft 4, and the second axle 9 can be selectively connected to the second motor 16 by power, that is, the power of the second motor 16 can be transmitted to the second axle 9, that is, the first axle 6 and the second axle 9 can be driven respectively, so that the front-wheel drive or rear-wheel drive operation of the vehicle can be realized, and the four-wheel drive operation of the vehicle can also be realized.

[0041] Therefore, by setting the first axle 6 and the second axle 9 in the power drive system 100, the present application can be applied to four-wheel vehicles, and by simultaneously setting the first motor 5, the second motor 16 and the engine 1 in the power drive system 100, the present application can be applied to hybrid vehicles, and the power of the engine 1 or the first motor 5 can be transmitted to the first axle 6, and the power of the second motor 16 can be transmitted to the second axle 9, so that the front-wheel drive or rear-wheel drive operation of the vehicle can be realized, and the four-wheel drive operation of the vehicle can also be further realized.

[0042] According to the power drive system 100 of the embodiment of the utility model, by setting the first axle 6 and the second axle 9, the present application can be applied to four-wheel vehicles, and by simultaneously setting the second motor 16, the engine 1 and the first motor 5, the present application can be applied to hybrid vehicles, and can respectively realize three different driving modes of the vehicle, namely front-wheel drive, rear-wheel drive and four-wheel drive, to meet user needs and help improve user satisfaction.

[0044] Specifically, the battery 8 is electrically connected to the first motor 5 and the second motor 16 respectively, so that the battery 8 can be used to provide electrical energy to the first motor 5 and the second motor 16 respectively. In addition, the battery 8 is set between the first axle 6 and the second axle 9, that is, the battery 8 can be set close to the center of the vehicle, which can make the center of gravity of the vehicle closer to the center of the vehicle to improve the driving stability of the vehicle, and can reduce the distance between the battery 8 and the first motor 5 and the second motor 16, so that the battery 8 can provide electrical energy to the first motor 5 and the second motor 16.

[0045] 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 first motor 5 are located on a side of the first axle 6 facing away from the second axle 9 .

[0049] In some embodiments, the second axle 9 is configured as a front axle of the vehicle and the first axle 6 is configured as a rear axle of the vehicle.

[0050] That is to say, the second axle 9 can be connected to the two wheels located on the front side of the vehicle at the same time, that is, the left front wheel 101 and the right front wheel 102 at the same time, and the first axle 6 can be connected to the two wheels located on the rear side of the vehicle at the same time, that is, the left rear wheel 103 and the right rear wheel 104 at the same time.

[0051] Furthermore, the power of the engine 1 or the first motor 5 can be transmitted to the first axle 6, driving the left rear wheel 103 and the right rear wheel 104 to rotate, thereby realizing the rear-wheel drive operation of the vehicle. The power of the second motor 16 can be transmitted to the second axle 9, driving the left front wheel 101 and the right front wheel 102 to rotate, thereby realizing the front-wheel drive operation of the vehicle, and thus the four-wheel drive operation of the vehicle can also be realized.

[0053] Specifically, a first driving gear 21 is sleeved on the outer side of the first input shaft 2, and a first driven gear 41 is sleeved on the outer side of the output shaft 4, and the first driving gear 21 is meshed with the first driven gear 41, so that the power on the first input shaft 2 is transmitted to the output shaft 4 through the cooperation between the first driving gear 21 and the first driven gear 41. At the same time, a second driving gear 31 is sleeved on the outer side of the second input shaft 3, and a second driven gear 42 is sleeved on the outer side of the output shaft 4, and the second driving gear 31 is meshed with the second driven gear 42, so that the power on the first input shaft 2 is transmitted to the output shaft 4 through the cooperation between the first driving gear 21 and the first driven gear 41. The cooperation between the second input shaft 31 and the second driven gear 42 transmits the power on the second input shaft 3 to the output shaft 4, and the engine 1 is selectively connected to the first input shaft 2 or the second input shaft 3, so that the power of the engine 1 can be transmitted from the first input shaft 2 to the output shaft 4 through the first driving gear 21 and the first driven gear 41, or the power of the engine 1 can be transmitted from the second input shaft 3 to the output shaft 4 through the second driving gear 31 and the second driven gear 42, and then transmitted to the first wheel shaft 6, driving the two wheels connected to the first wheel shaft 6 to rotate, that is, driving the vehicle to run.

[0054] The first 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 driven gear 41 or the second driven gear 42 .

[0055] Specifically, by connecting the first motor 5 to the motor input gear 51, the power of the first 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 power of the first driven gear 41, or connected to the power of the second driven gear 42. When the motor input gear 51 is connected to the first driven gear 41, the power of the first motor 5 can be transmitted to the first driven gear 41 through the motor input gear 51, that is, transmitted to the output shaft 4. When the motor input gear 51 is connected to the second driven gear 42, the power of the first motor 5 can be transmitted to the second driven gear 42 through the motor input gear 51, that is, transmitted to the output shaft 4, and then transmitted to the first wheel axle 6 to drive the vehicle to run.

[0056] 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.

[0057] Specifically, the first driving gear 21 is meshed with the first driven gear 41, and the power on 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 can be transmitted through multiple groups of first driving gears 21 and multiple groups of first driven gears 41, and the multiple groups of first driving gears 21 and 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 provided to match it, which can improve the reliability of power transmission using the first driving gear 21 and the first driven gear 41.

[0058] 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.

[0059] 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.

[0060] The second driving gears 31 and the second driven gears 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 .

[0061] Specifically, the second driving gear 31 is meshed with the second driven gear 42, and the power on the second input shaft 3 can be transmitted from the second driving gear 31 to the second driven gear 42.

[0062] 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.

[0063] 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.

[0064] 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.

[0066] Specifically, the motor input gear 51 can be connected to one of the first driven gears 41, or connected to one of the second driven gears 42, so that the power of the first motor 5 can be transmitted to the output shaft 4 through the first driven gear 41 or the second driven gear 42 connected to the motor input gear 51, and then transmitted to the first wheel axle 6 to drive the vehicle to run.

[0067] In some embodiments, the output shaft 4 is further provided with an output gear 43 , and the output gear 43 is used for power connection with the first axle 6 , and the output gear 43 is located between the plurality of first driven gears 41 and the plurality of second driven gears 42 .

[0068] Specifically, an output gear 43 is provided on the output shaft 4, so that the power on the output shaft 4 can be transmitted outward through the output gear 43, and the output gear 43 is connected to the power of the first wheel axle 6, so that the power on the output shaft 4 can be transmitted to the first wheel axle 6 through the output gear 43, thereby driving the vehicle to run, and the output gear 43 is provided between multiple groups of first driven gears 41 and multiple groups of second driven gears 42, so that the distance between the output gear 43 and the first driven gear 41 and the second driven gear 42 can be made closer, thereby improving the power transmission efficiency.

[0069] In some embodiments, the motor input gear 51 is power-connected to one of the one or more second driven gears 42 closest to the output gear 43 among the plurality of first driven gears 41 .

[0070] Specifically, the motor input gear 51 can be power-connected to a first driven gear 41 among multiple first driven gears 41 that is closest to the output gear 43, so that the power of the first motor 5 can be transmitted to the output gear 43 through the first driven gear 41, and then transmitted to the first wheel axle 6, or the motor input gear 51 can be power-connected to a second driven gear 42 among multiple second driven gears 42 that is closest to the output gear 43, so that the power of the first motor 5 can be transmitted to the output gear 43 through the second driven gear 42, and then transmitted to the first wheel axle 6 to drive the vehicle to run.

[0071] In such Figure 1-Figure 2 In the illustrated embodiment, the motor input gear 51 is power-connected to a second driven gear 42 closest to the output gear 43, so that the power of the first motor 5 can be transmitted to the output shaft 4 through the second driven gear 42, and the second driving gear 31 meshing with the second driven gear 42 is selectively power-connected to the second input shaft 3 through the first synchronizer 13. When the second driving gear 31 is power-connected to the second input shaft 3, the power of the engine 1 can be transmitted to the output shaft 4, or the engine 1 can generate electricity for the first motor 5 through the second driving gear 31.

[0072] Furthermore, it should be noted that, in a specific design, the motor input gear 51 may be dynamically connected to other first driven gears 41 or second driven gears 42 according to specific requirements and actual conditions.

[0073] And, it should be noted that if Figure 1-Figure 2As shown, a transmission shaft 44 is also provided between the output shaft 4 and the first axle 6, and the transmission shaft 44 is connected to the first axle 6 through a main reducer 46, and a transmission gear 45 is sleeved on the transmission shaft 44, and the transmission gear 45 is meshed with the output gear 43, so that the power of the engine 1 or the first motor 5 can be transmitted from the output shaft 4 through the transmission shaft 44 and the main reducer 46 to the first axle 6 through the cooperation between the output gear 43 and the transmission gear 45.

[0074] In addition, this application can realize multiple working modes of the vehicle, as follows:

[0075] When the second motor 16 is not working and the engine 1 is disconnected from the first input shaft 2 and the second input shaft 3, the third synchronizer 15 can be used to connect the second driven gear 42 meshing with the motor input gear 51 to the output shaft 4, so as to transmit the power of the first motor 5 to the output shaft 4, thereby realizing the rear-wheel drive operation of the vehicle in the pure electric mode. When both the engine 1 and the first motor 5 are not working, the battery 8 can be used to provide electrical energy to the second motor 16, thereby realizing the front-wheel drive operation of the vehicle in the pure electric mode. Moreover, when the engine 1 is not working, the first motor 5 and the second motor 16 respectively drive the first axle 6 and the second axle 9, that is, they drive the vehicle together to realize the four-wheel drive operation of the vehicle in the pure electric mode.

[0076] When the battery 8 is low in power or in certain specific operating conditions, such as high-speed cruising, the first motor 5 and the second motor 16 do 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 a pure internal combustion engine mode. In addition, when the battery 8 is low in power or in certain specific operating conditions, the engine 1 can be used to generate electricity for the first motor 5, and the electricity generated by the first motor 5 can drive the second motor 16 to operate, thereby realizing the operation of the vehicle in an extended-range mode.

[0077] When the engine 1 is connected to the second input shaft 3, the motor input gear 51 is power-connected to the second driven gear 42 close to the output gear 43, and the second driving gear 31 meshing with the second driven gear 42 is power-connected to the second input shaft 3 under the action of the first synchronizer 13, the engine 1 and the first motor 5 can jointly drive the first wheel axle 6 to realize rear-wheel drive operation of the vehicle in hybrid mode. In addition, when the demand for power is large, such as in track conditions, the first motor 5, the second motor 16 and the engine 1 can drive the vehicle at the same time to realize parallel four-wheel drive of the vehicle in hybrid mode. This mode is the most powerful mode.

[0078] When the second synchronizer 14 and the third synchronizer 15 are both disconnected, the engine 1 is connected to the second input shaft 3, and the first synchronizer 13 is engaged, the engine 1 can generate electricity for the first 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 first motor 5 and store it in the battery 8, thereby realizing the vehicle's driving power generation mode, and this mode can only be achieved through the first synchronizer 13 when the second clutch 12 is engaged; the wheel torque can be transmitted to the first motor 5 for braking energy recovery, thereby realizing the vehicle's braking energy recovery.

[0079] The utility model also provides a vehicle.

By providing the first axle 6 and the second axle 9, the present application can be applied to four-wheel vehicles, and by providing the second motor 16, the engine 1 and the first motor 5 at the same time, the present application can be applied to hybrid vehicles, and three different driving modes of front-wheel drive, rear-wheel drive and four-wheel drive of the vehicle can be realized respectively, so as to meet user needs and help improve user satisfaction.
