[0076] The hybrid power system 1 according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0077] As shown in FIGS. 1-27, the hybrid power system 1 according to the embodiments of the present disclosure includes a first motor 100, an engine 200, an input shaft 300, an output shaft 400, and a clutch 600.

[0078] The first motor 100 is in driving connection with the input shaft 300, and the engine 200 is selectively in driving connection with the input shaft 300, the output shaft 400 is configured to output power to wheels, and the clutch 600 is arranged between the input shaft 300 and the output shaft 400 to selectively connect the input shaft 300 with the output shaft 400 in driving connection.

[0079] In the embodiments of the present disclosure, the engine 200 and the first motor 100 can be arranged in a longitudinal direction.

[0080] In the embodiments of the present disclosure, the engine 200 is selectively in driving connection with the input shaft 300, which means that the engine 200 can be in driving connection with the input shaft 300, or the engine 200 can be disconnected from the input shaft 300 in power transmission.

[0081] In addition, a torsional damper 220 can be arranged between the engine shaft 210 of the engine 200 and the input shaft 300, so that the output torque of the engine 200 can be avoided to be too large, so that the engine 200 can stably output power.

[0082] For example, the output shaft 400 can be configured to output power to the front wheels 920 of the vehicle, i.e., the first motor 100 and the engine 200 are configured to hybrid drive the front wheels 920 of the vehicle.

[0083] According to the hybrid power system 1 provided by the embodiment of the present disclosure, by drivingly connecting the first motor 100 with the input shaft 300 and selectively drivingly connecting the engine 200 with the input shaft 300, when the engine 200 is disconnected from the input shaft 300, the first motor 100 can be used to drive the front wheels 920 of the vehicle alone, or when the engine 200 is connected with the input shaft 300, the engine 200 can be used to drive the front wheels 920 of the vehicle alone, or the engine 200 and the first motor 100 can be used to drive the front wheels 920 of the vehicle in combination, and thus the vehicle can be driven to move.

[0084] Further, in the front drive part of the hybrid power system 1, only one first motor 100 is needed, which can be used as a driving motor in corresponding working conditions and can also be used as a generator in specific working conditions, so that the structure of the hybrid power system 1 can be simplified, the number of motors and the number of related gears of the hybrid power system 1 can be reduced, and thus the cost of the hybrid power system 1 can be reduced and the structure of the hybrid power system 1 can be more compact.

[0085] In addition, the clutch 600 is arranged between the input shaft 300 and the output shaft 400 to selectively drivingly connect the input shaft 300 with the output shaft 400, so that the power transmission between the input shaft 300 and the output shaft 400 can be selectively connected or disconnected by the clutch 600, and thus the power output of the engine 200 and the first motor 100 can be controlled, or the input shaft 400 can also transmit power to the output shaft 400 through the different gear pairs 510 by the clutch 600, and thus the vehicle can be driven to move in different gears.

[0086] In addition, by arranging the clutch 600, for example, the clutch 600 can be arranged between shafts to control the power transmission and interruption between the shafts, or the clutch 600 can be arranged corresponding to the gear pairs 510, when one clutch 600 is combined with a corresponding gear pair 510, the input shaft 300 can transmit power to the output shaft 400 through the gear pair 510, that is, the clutch 600 can control the power transmission and interruption between the shaft and the gear. By arranging in this way, the switching of the power transmission path of the hybrid power system 1 can be simplified, the hybrid power system 1 can be switched to different gears for power output, and the clutch 600 occupies less space and has a simpler structure, which is beneficial to make the structure of the hybrid power system 1 more compact and facilitate the layout of the hybrid power system 1.

[0087] Therefore, the hybrid power system 1 provided by the embodiment of the present disclosure has the advantages of simple structure, compact structure, small space occupation and easy switching of the driving path.

[0088] In some embodiments of the present disclosure, as shown in FIG. 1, the transmission mechanism 500 has a gear pair 510, the gear pair 510 is arranged between the input shaft 300 and the output shaft 400, the clutch 600 is arranged on the input shaft 300 and / or the output shaft 400, and the clutch 600 connects or disconnects the input shaft 300 and / or the output shaft 400 with the gear pair 510, so that the input shaft 300 is selectively drivingly connected with the output shaft 400 through the gear pair 510.

[0089] Therefore, when the hybrid power system 1 needs to transmit power through the input shaft 300 and the output shaft 400, the clutch 600 can be combined, so that the input shaft 300 can transmit power to the output shaft 400 through the gear pair 510 to drive the vehicle to travel.

[0090] In addition, the gear pair 510 can also be multiple, so that the input shaft 300 can be drivingly connected to the output shaft 400 through the clutch 600 and different gear pairs 510, thereby realizing driving the vehicle to travel at different gears.

[0091] In some specific embodiments of the present disclosure, as shown in FIGS. 2, 17-19, the hybrid power system 1 further comprises a second motor 110 and a power battery 120.

[0092] The second motor 110 is used to drive one of the front wheels 920 and the rear wheels 930 of the vehicle, the engine 200 and the first motor 100 are used to drive the other of the front wheels 920 and the rear wheels 930 of the vehicle, and the power battery 120 is arranged between and electrically connected with the first motor 100 and the second motor 110, so that the power battery 120 can supply power to the first motor 100 and the second motor 110 respectively.

[0093] For example, the engine 200 and the first motor 100 can be used to drive the front wheels 920 of the vehicle, and the second motor 110 can be used to drive the rear wheels 930 of the vehicle. Therefore, the hybrid power system 1 can realize pure electric front drive, hybrid front drive, engine direct drive front drive, pure electric rear drive, and pure electric four-wheel drive and hybrid four-wheel drive.

[0094] By adding the second motor 110 to drive the rear wheels 930, when the power battery 120 has a low power, the second motor 110 can be used to drive the rear wheels 930, and the first motor 100 can generate electricity, or the second motor 110 can be used to drive the rear wheels 930, and the first motor 100 can generate electricity while driving the front wheels 920, so that the problem of large power performance attenuation when the power battery 120 has a low power can be avoided, and the driving force of the hybrid power system 1 is more sufficient.

[0095] In addition, the hybrid system 1 can further be provided with a plurality of motor controllers 130, and the plurality of motor controllers 130 are respectively connected with the first motor 100 and the second motor 110 in one-to-one correspondence, so as to control the first motor 100 and the second motor 110 to operate through the motor controllers 130.

[0096] In addition, the power output by the second motor 110 can also be transmitted to the wheels through the reducer and the differential 900.

[0097] In some embodiments of the present disclosure, as shown in FIGS. 2, 17-19, the plurality of gear pairs 510 includes a first gear pair 520 and a second gear pair 530. The transmission ratios of the first gear pair 520 and the second gear pair 530 are different.

[0098] Specifically, the clutch 600 is switchably connected with one of the first gear pair 520 and the second gear pair 530, so that the input shaft 300 is selectively drivingly connected with the output shaft 400 through one of the first gear pair 520 and the second gear pair 530.

[0099] The input shaft 300 and / or the output shaft 400 are connected or disconnected with the first gear pair 520 or the second gear pair 530 by the clutch 600, which means that the input shaft 300 or the output shaft 400 can be drivingly connected with the first gear pair 520 through the clutch 600, at this time the input shaft 300 can transmit power to the output shaft 400 through the first gear pair 520, or the input shaft 300 or the output shaft 400 can be drivingly connected with the second gear pair 530 through the clutch 600, at this time the input shaft 300 can transmit power to the output shaft 400 through the second gear pair 530.

[0100] Therefore, by switching the state of the clutch 600, the power output path of the hybrid system 1 can be switched, that is, the power can be selected to be transmitted to the output shaft 400 through the first gear pair 520 or the second gear pair 530, so that the power switching is more convenient.

[0101] In some embodiments of the present disclosure, as shown in FIGS. 2, 17 and 18, the clutch 600 is a plurality of clutches, and the plurality of clutches 600 includes a first clutch 610 and a second clutch 620, the first clutch 610 connects or disconnects the input shaft 300 and / or the output shaft 400 with the first gear pair 520, and the second clutch 620 connects or disconnects the input shaft 300 and / or the output shaft 400 with the second gear pair 530.

[0102] The first clutch 610 connects or disconnects the input shaft 300 and / or the output shaft 400 with the first gear pair 520, which means that the input shaft 300 can be controlled to output power to the output shaft 400 through the first gear pair 520 by engaging the first clutch 610.

[0103] The second clutch 620 connects or disconnects the input shaft 300 and / or the output shaft 400 with the second gear pair 530, which means that the input shaft 300 can be controlled to output power to the output shaft 400 through the second gear pair 530 by engaging the second clutch 620.

[0104] That is, the clutch 600 is a single clutch, when the hybrid power system 1 needs to drive the front wheels 920 to rotate, one of the first clutch 610 and the second clutch 620 can be engaged, and the other of the first clutch 610 and the second clutch 620 can be disengaged. In this way, the structure of the clutch 600 can be simpler and occupy less space, which is convenient for arrangement, and further simplifies the structure of the hybrid power system 1, so that the structure of the hybrid power system 1 is more compact, and the switching of the output path of the hybrid power system 1 is more simple.

[0106] The first clutch 610 connects or disconnects the input shaft 300 or the output shaft 400 with the first gear 521, or the first clutch 610 connects or disconnects the input shaft 300 or the output shaft 400 with the second gear 522, which means that the first clutch 610 can control the power transmission at the first gear 521 or the second gear 522. Thus, when the first clutch 610 is engaged, the input shaft 300 can transmit power to the output shaft 400 through the first gear pair 520.

[0107] In addition, the second clutch 620 connects or disconnects the input shaft 300 or the output shaft 400 with the third gear 531, or the second clutch 620 connects or disconnects the input shaft 300 or the output shaft 400 with the fourth gear 532, which means that the second clutch 620 can control the power transmission at the third gear 531 or the fourth gear 532. Thus, when the second clutch 620 is engaged, the input shaft 300 can transmit power to the output shaft 400 through the second gear pair 530.

[0108] In some embodiments of the present disclosure, as shown in FIG. 2, the first gear 521 and the third gear 531 are arranged on the input shaft 300, and the second gear 522 and the fourth gear 532 are arranged on the output shaft 400.

[0109] In some embodiments of the present disclosure, as shown in FIG. 2, the first gear 521 and the third gear 531 are arranged on the input shaft 300, and the second gear 522 and the fourth gear 532 are arranged on the output shaft 400.

[0110] Thus, the first clutch 610 can be arranged on the input shaft 300 and control the power transmission between the input shaft 300 and the first gear 521, while the second clutch 620 can be arranged on the input shaft 300 and control the power transmission between the input shaft 300 and the third gear 531; or the first clutch 610 can be arranged on the input shaft 300 and control the power transmission between the input shaft 300 and the first gear 521, while the second clutch 620 can be arranged on the output shaft 400 and control the power transmission between the output shaft 400 and the fourth gear 532; or the first clutch 610 can be arranged on the output shaft 400 and control the power transmission between the output shaft 400 and the second gear 522, while the second clutch 620 can be arranged on the input shaft 300 and control the power transmission between the input shaft 300 and the third gear 531; or the first clutch 610 can be arranged on the output shaft 400 and control the power transmission between the output shaft 400 and the second gear 522, while the second clutch 620 can be arranged on the output shaft 400 and control the power transmission between the output shaft 400 and the fourth gear 532.

[0111] That is, the first clutch 610 and the second clutch 620 can be arranged on the input shaft 300 or the output shaft 400 at the same time, or one of the first clutch 610 and the second clutch 620 can be arranged on the input shaft 300 and the other on the output shaft 400.

[0112] Further, as shown in FIG. 2, the first clutch 610 is arranged on one of the input shaft 300 and the output shaft 400, and the second clutch 620 is arranged on the other one of the input shaft 300 and the output shaft 400. In this way, the first clutch 610 and the second clutch 620 can be staggered on different shafts, which is conducive to reducing the space occupied by the clutch 600 in the longitudinal direction of the hybrid power system 1.

[0113] In some embodiments of the present disclosure, as shown in FIG. 2, the hybrid power system 1 further comprises a speed reduction mechanism 800, which comprises a first output gear 810 and a second output gear 820.

[0114] The first output gear 810 is arranged on and connected to the motor shaft 101 of the first motor 100, the second output gear 820 is arranged on and connected to the input shaft 300, and the first output gear 810 and the second output gear 820 are engaged.

[0115] Here, the transmission ratio of the first output gear 810 and the second output gear 820 is greater than 1. In this way, the power of the first motor 100 can be transmitted to the input shaft 300 through the first output gear 810 and the second output gear 820, which is conducive to increasing the output torque of the first motor 100 and making the power output of the first motor 100 more powerful.

[0116] Moreover, by arranging the speed reduction mechanism 800 to connect the motor shaft 101 of the first motor 100 and the input shaft 300, the motor shaft 101 and the input shaft 300 can be staggered in the radial direction of the input shaft 300, thereby reducing the space occupied by the motor shaft 101 and the input shaft 300 in the longitudinal direction of the hybrid power system 1, so that the longitudinal structure of the hybrid power system 1 is more compact.

[0117] In some embodiments of the present disclosure, as shown in FIGS. 2, 17-19, the hybrid power system 1 further comprises a third clutch 310 arranged between the engine shaft 210 of the engine 200 and the input shaft 300 to connect or disconnect the engine shaft 210 and the input shaft 300.

[0118] Specifically, by engaging the third clutch 310, the power of the engine 200 can be transmitted to the input shaft 300 through the third clutch 310, and then transmitted rearward through the input shaft 300, for example, the power can be transmitted to the output shaft 400 through the input shaft 300 to drive the wheels to rotate, or the power can be transmitted to the first motor 100 through the input shaft 300, and then the first motor 100 can be driven to generate electricity. When the third clutch 310 is disengaged, the power of the engine 200 is interrupted, and at this time the engine 200 does not participate in the power driving of the hybrid power system 1.

[0119] Thus, by setting the third clutch 310, separate driving of the first motor 100 can be achieved, or hybrid driving of the first motor 100 and the engine 200 can be achieved.

In this way, the transmission direction of power can be changed through the cooperation of the first bevel gear 910 and the second bevel gear 420, i.e., the power transmission in the axial direction of the output shaft 400 can be changed to power transmission in the radial direction of the output shaft 400.

[0121] Further, the first gear pair 520 and the second gear pair 530 can be directly arranged on the output shaft 400, and the shaft end of the output shaft 400 can be directly connected with the differential 900 through the second bevel gear 420, further simplifying the structure of the hybrid power system 1, which is conducive to simplifying the number of gears of the hybrid power system 1, making the power transmission structure simpler, and facilitating arrangement.
