[0039] In other words, if Figures 1 to 6 As shown, the drive system 100 according to the embodiment of the utility model can be applied to a vehicle, and the drive system 100 mainly includes a transmission assembly 10, a first motor 20, a second motor 30, a first output half shaft 40 and a second output half shaft 60, wherein the transmission assembly 10 has an input part for power input, a first output part for outputting power, and a second output part for outputting power, and the second output part is located at an end of the transmission assembly 10 away from the first output part. The output shaft of the first motor 20 can be connected to the input part of the transmission assembly 10 in a transmission manner, so that the power of the first motor 20 can be transmitted to the first output part and the second output part of the transmission assembly 10, and the output shaft of the second motor 30 can also be connected to the input part of the transmission assembly 10 in a transmission manner, so that the power of the second motor 30 can be transmitted to the first output part and the second output part of the transmission assembly 10.

[0040] The transmission assembly 10 is located between the first output half shaft 40 and the second output half shaft 60. The first output half shaft 40 can be the left output half shaft of the vehicle, and the second output half shaft 60 can be the right output half shaft of the vehicle. The first end of the first output half shaft 40 is suitable for connecting to the left wheel of the vehicle, and the second end of the first output half shaft 40 is connected to the first output part of the transmission assembly 10 through the first decoupling member 50, that is, the first decoupling member 50 has a first part and a second part, the first part of the first decoupling member 50 can be non-rotatably connected to the second end of the first output half shaft 40, the second part of the first decoupling member 50 can be non-rotatably connected to the first output part, and the first decoupling member 50 can be switched between a coupled state and a decoupled state.

The first end of the second output axle 60 is suitable for connecting to the right wheel of the vehicle. The second output axle 60 can be connected to the second output part of the transmission assembly 10 directly or through other connection structures, so that the second output part can transmit power to the second output axle 60 to drive the second output axle 60 to rotate.

[0042] Therefore, according to the drive system 100 of the embodiment of the utility model, the power output path of the first output half shaft 40 and the transmission assembly 10 can be controlled by the first decoupling member 50 provided between the first output half shaft 40 and the transmission assembly 10, so that when the power output path of the first output half shaft 40 and the transmission assembly 10 is connected, the drive system 100 can distribute the power of the first motor 20 and / or the second motor 30 to two wheels; when the power output path of the first output half shaft 40 and the transmission assembly 10 is disconnected, the drive system 100 can distribute the power of the first motor 20 and / or the second motor 30 to only one wheel, thereby increasing the driving mode of the vehicle and facilitating the use of the vehicle under special working conditions.

[0043] According to one embodiment of the utility model, the drive system 100 also includes: a second decoupling member 70, the second output half shaft 60 is connected to the second output part through the second decoupling member 70, and the second decoupling member 70 is suitable for connecting or disconnecting the power transmission path between the second output half shaft 60 and the second output part.

[0044] Specifically, the second end of the second output half shaft 60 is connected to the second output part of the transmission assembly 10 through the second decoupling member 70, that is, the second decoupling member 70 has a first part and a second part, the first part of the second decoupling member 70 can be non-rotatably connected to the second end of the second output half shaft 60, the second part of the second decoupling member 70 can be non-rotatably connected to the second output part, and the second decoupling member 70 can be switched between a coupled state and a decoupled state.

[0045] When the second decoupling member 70 is in a coupled state, the first part of the second decoupling member 70 is coupled with the second part, the power transmission path between the second output half shaft 60 and the second output part is connected, and the second output part can transmit power to the second output half shaft 60 to drive the second output half shaft 60 to rotate; when the second decoupling member 70 is switched to a decoupling state, the first part of the second decoupling member 70 is decoupled from the second part, the power transmission path between the second output half shaft 60 and the second output part is disconnected, and the second output part will not transmit power to the second output half shaft 60.

[0046] In this embodiment, by switching the states of the first decoupling component 50 and the second decoupling component 70, the drive system 100 can not only distribute the power of the first motor 20 and / or the second motor 30 to the left wheel only, but also distribute the power of the first motor 20 and / or the second motor 30 to the right wheel only, which can further increase the adaptability of the vehicle to working conditions.

[0047] In some specific embodiments of the present invention, the drive system 100 also includes: a first clutch assembly 80, the second output half shaft 60 is connected to the output shaft of the second motor 30 through the first clutch assembly 80, and the first clutch assembly 80 is suitable for connecting or disconnecting the power transmission path between the second output half shaft 60 and the output shaft of the second motor 30.

[0048] That is to say, in order to facilitate the direct driving of the second output half shaft 60 to rotate by the second motor 30, the output shaft of the second motor 30 can also be connected to the second output half shaft 60 through the first clutch assembly 80. The first clutch assembly 80 can be switched between an engaged state and a disengaged state. When the first clutch assembly 80 is in the engaged state, the power transmission path between the second output half shaft 60 and the output shaft of the second motor 30 is connected, and the power of the second motor 30 can be transmitted to the right wheel through the first clutch assembly 80 and the second output half shaft 60, which is beneficial to distribute the power of the second motor 30 only to the right wheel. When the first clutch assembly 80 is in the disengaged state, the power transmission path between the second output half shaft 60 and the output shaft of the second motor 30 is disconnected, and the second output half shaft 60 can be driven by the second end of the transmission assembly 10.

[0050] Specifically, the first clutch assembly 80 mainly includes a first gear set 81 and a first clutch 82, wherein the first gear set 81 may include a first large gear 811 and a first small gear 812, the first large gear 811 is sleeved on the second output half shaft 60 and the two are fixedly connected, the first small gear 812 is rotatable around its own axis, and the first small gear 812 is meshed with the first large gear 811, the first clutch 82 has a first part and a second part, the first part of the first clutch 82 is non-rotatably connected to the output end of the second motor 30, the second part of the first clutch 82 is non-rotatably connected to an end of the first small gear 812 close to the second motor 30, and the first clutch 82 is switchable between a coupled state and a disengaged state.

[0051] When the first clutch 82 is in an engaged state, the first clutch assembly 80 is in an engaged state, and when the first clutch 82 is in a disengaged state, the first clutch assembly 80 is in a disengaged state. The working state of the first clutch assembly 80 can be switched by switching the state of the first clutch 82. The structure is simple and easy to operate.

[0052] In some specific embodiments of the present invention, the drive system 100 also includes: a second clutch assembly 90, the output shaft of the first motor 20 and the output shaft of the second motor 30 are connected to the input part through the second clutch assembly 90, and the second clutch assembly 90 is suitable for connecting or disconnecting the power transmission path between the output shaft of the first motor 20 and the input part, and connecting or disconnecting the power transmission path between the output shaft of the second motor 30 and the input part.

Thus, by controlling the connection and disconnection of different power transmission paths, the drive system 100 can be switched between different single-motor drive modes and dual-motor drive modes, and can be applied to different working conditions.

[0054] According to one embodiment of the utility model, the second clutch assembly 90 includes: a second gear set 91, a second clutch 92 and a third clutch 93, the second gear set 91 is connected to the input part, the output shaft of the first motor 20 is connected to the second gear set 91 through the second clutch 92, the second clutch 92 is suitable for connecting or disconnecting the power transmission path between the first motor 20 and the second gear set 91, the output shaft of the second motor 30 is connected to the second gear set 91 through the third clutch 93, and the third clutch 93 is suitable for connecting or disconnecting the power transmission path between the output shaft of the second motor 30 and the second gear set 91.

[0055] Specifically, the second clutch assembly 90 mainly includes a second gear set 91, a second clutch 92 and a third clutch 93. The second gear set 91 may include a second large gear 911 and a second small gear 912. The second large gear 911 is sleeved on the input part of the transmission assembly 10 and the two are fixedly connected. The second small gear 912 is located between the first motor 20 and the second motor 30.

When the second clutch 92 is in a coupled state, the first part of the second clutch 92 is coupled to the second part, the power transmission path between the output shaft of the first motor 20 and the second pinion 912 is connected, and the power of the first motor 20 can be transmitted to the input part through the second gear set 91, and output from the first output part and the second output part; when the second clutch 92 is in a disengaged state, the first part of the second clutch 92 is separated from the second part, and the power transmission path between the output shaft of the first motor 20 and the second pinion 912 is disconnected.

[0057] The third clutch 93 has a first part and a second part, the first part of the third clutch 93 is connected to the output end of the second motor 30 in a non-rotatable manner, the second part of the third clutch 93 is connected to the end of the second pinion 912 close to the second motor 30 in a non-rotatable manner, and the third clutch 93 can be switched between a coupled state and a disengaged state. When the third clutch 93 is in a coupled state, the first part of the third clutch 93 is coupled to the second part, the power transmission path between the output shaft of the second motor 30 and the second pinion 912 is connected, and the power of the second motor 30 can be transmitted to the input part through the second gear set 91, and output from the first output part and the second output part; when the third clutch 93 is in a disengaged state, the first part of the third clutch 93 is separated from the second part, and the power transmission path between the output shaft of the second motor 30 and the second pinion 912 is disconnected.

[0058] Thus, by controlling the states of the second clutch 92 and the third clutch 93, the connection and disconnection of different power transmission paths can be controlled, so that the drive system 100 can be switched between different single-motor drive modes and dual-motor drive modes. The drive system 100 can be switched between different single-motor drive modes and dual-motor drive modes, can be adapted to different working conditions, and has a simple structure and is easy to operate.

[0059] In some specific embodiments of the present invention, the output shaft of the second motor 30 includes a first output shaft 31 and a second output shaft 32, wherein the first output shaft 31 is located at an end of the second motor 30 away from the first motor 20, and the first output shaft 31 is suitable for connecting to the first clutch assembly 80, and the second output shaft 32 is located at an end of the second motor 30 close to the first motor 20, and the second output shaft 32 is suitable for connecting to the second clutch assembly 90.

[0060] That is to say, the second motor 30 can be a dual-output shaft motor, and the second motor 30 is located between the first clutch assembly 80 and the second clutch assembly 90. The second motor 30 has a first output shaft 31 at one end close to the first clutch assembly 80, and the first output shaft 31 is non-rotatably connected to the first part of the first clutch 82 of the first clutch assembly 80. The second motor 30 has a second output shaft 32 at one end close to the second clutch assembly 90, and the second output shaft 32 is non-rotatably connected to the first part of the third clutch 93 of the second clutch assembly 90.

[0061] In this embodiment, the second motor 30 has dual output shafts, which can simplify the transmission structure of the drive system 100 and the occupied space, which is beneficial to the layout of the entire vehicle.

[0063] In other words, in order to facilitate the direct driving of the first output half-shaft 40 to rotate by the first motor 20, the output shaft of the first motor 20 can also be connected to the first output half-shaft 40 through the third clutch assembly. The third clutch assembly can be switched between an engaged state and a disengaged state. When the third clutch assembly is in the engaged state, the power transmission path between the first output half-shaft 40 and the output shaft of the first motor 20 is connected, and the power of the first motor 20 can be transmitted to the right wheel through the third clutch assembly and the first output half-shaft 40, which is beneficial to distribute the power of the first motor 20 only to the left wheel. When the third clutch assembly is in the disengaged state, the power transmission path between the first output half-shaft 40 and the output shaft of the first motor 20 is disconnected, and the first output half-shaft 40 can be driven by the first end of the transmission assembly 10.

[0064] In this embodiment, the power transmission path between the first output half shaft 40 and the output shaft of the first motor 20 is connected. When the power transmission path between the output shaft of the first motor 20 and the output part of the transmission assembly 10 is disconnected, the power of the first motor 20 can be directly transmitted to the first output half shaft 40 without passing through the transmission assembly 10, thereby avoiding energy loss.

[0065] In some optional examples of the present invention, the first motor 20 is a dual-output shaft motor, and the third clutch assembly has the same structure as the first clutch assembly 80, which will not be described in detail in this example.

[0066] In some specific embodiments of the present invention, the transmission assembly 10 is configured as a differential, through which the rotational speed and torque of the wheels on both sides can be changed during operation, and the differential also has a differential lock.

[0067] In some optional examples of the present invention, the first decoupling member 50 and the second decoupling member 70 may both be hydraulic clutches or electric couplers, and the first clutch 82 , the second clutch 92 and the third clutch 93 may all be hydraulic clutches.

[0068] In addition, the first decoupling member 50, the second decoupling member 70, the first clutch 82, the second clutch 92 and the third clutch 93 can also be selected according to actual needs, and will not be described in detail in this embodiment.

[0069] In summary, according to the drive system 100 of the embodiment of the utility model, the power output path of the first output half shaft 40 and the transmission assembly 10 can be controlled by the first decoupling member 50 set between the first output half shaft 40 and the transmission assembly 10, so that when the power output path of the first output half shaft 40 and the transmission assembly 10 is connected, the drive system 100 can distribute the power of the first motor 20 and / or the second motor 30 to two wheels. When the power output path of the first output half shaft 40 and the transmission assembly 10 is disconnected, the drive system 100 can distribute the power of the first motor 20 and / or the second motor 30 to only one wheel, thereby increasing the driving mode of the vehicle and facilitating the use of the vehicle under special working conditions.

[0070] An embodiment of the present invention further provides a vehicle, comprising the drive system 100 described in any of the above embodiments.

During the operation, the wheel speed and torque on both sides can be changed.

[0072] like Figure 3 As shown, if the vehicle according to the embodiment of the utility model encounters a special situation (such as a malfunction), the second motor 30 cannot output power, then the first motor 20 drives the wheels on both sides at the same time, the second clutch 92 is in a coupled state, the first clutch 82 and the third clutch 93 are in a disengaged state, and the first decoupling member 50 and the second decoupling member 70 are in a coupled state; the power of the first motor 20 is transmitted to the first output half shaft 40 and the second output half shaft 60 through the second gear set 91 and the differential; that is, the power of the first motor 20 is transmitted to the wheels on both sides through the second gear set 91 and the differential, so as to realize the normal operation of the vehicle. At the same time, due to the presence of the differential, the changes in the wheel speed and torque on both sides during the operation process can also be realized.
