As some embodiments of this application, the shift drive gear 50 and the connecting part 73 are constructed as an integral molded part.

[0090] This configuration facilitates the engagement of the second coupling 72 with the shift gear pair 64, enabling rapid and reliable shifting and allowing for flexible mode switching of the drive assembly 100.

[0091] In some embodiments of this utility model, such as Figure 1 As shown, the vehicle's drive assembly 100 also includes a second clutch 44, which is connected between the engine 10 and the drive shaft 1, and the engine 10 and the drive shaft 1 are selectively connected via the second clutch 44.

[0092] The second clutch 44 is connected between the engine 10 and the drive shaft 1 to allow selective connection between the engine 10 and the drive shaft 1. As some embodiments of this application, the second clutch 44 can be constructed as, but is not limited to, an electromagnetic clutch, a magnetic powder clutch, a friction clutch, a hydraulic clutch, etc. Of course, the second clutch 44 can also be constructed as other types of second clutch 44. It is understood that the specific type of the second clutch 44 can be selected according to actual needs, and this application does not limit it in this regard.

[0093] By setting a second clutch 44 and connecting the second clutch 44 between the engine 10 and the drive shaft 1, selective engagement between the engine 10 and the drive shaft 1 can be achieved. Furthermore, this arrangement ensures a reliable connection between the engine 10 and the drive shaft 1, which is beneficial to improving the operational reliability of the drive assembly 100.

The first shift drive gear 51 meshes with the first shift driven gear 61 and is configured as a first shift gear pair 53. The second shift drive gear 52 meshes with the second shift driven gear 62 and is configured as a second shift gear pair 63. The first shift gear pair 53 and the second shift gear pair 63 have different transmission ratios.

[0095] Along the axial direction of the first output shaft 2 (i.e. Figure 1 (in the X direction shown), the first shift driven gear 61 and the second shift driven gear 62 are respectively disposed on both sides of the second coupling 72, and the first shift gear pair 53 and the second shift gear pair 63 have a coupling portion 73 on the side facing the second coupling 72.

[0096] As some embodiments of this application, such as Figures 1-3 , Figure 5 and Figure 6 As shown, the first shift drive gear 51 and the second shift drive gear 52 are both integrated into the gear ring 43, while the first shift driven gear 61 and the second shift driven gear 62 are loosely fitted onto the first output shaft 2. The first shift drive gear 51 meshes with the first shift driven gear 61 and is constructed as a first shift gear pair 53, and the second shift drive gear 52 meshes with the second shift driven gear 62 and is constructed as a second shift gear pair 63. The first shift gear pair 53 and the second shift gear pair 63 have different transmission ratios, resulting in different output power from the first output shaft 2.

[0097] As some embodiments of this application, such as Figure 4 As shown, the first shift drive gear 51 and the second shift drive gear 52 are both loosely fitted onto the gear ring 43. The first shift driven gear 61 and the second shift driven gear 62 are both connected to the first output shaft 2. The first shift drive gear 51 meshes with the first shift driven gear 61 and is constructed as a first shift gear pair 53. The second shift drive gear 52 meshes with the second shift driven gear 62 and is constructed as a second shift gear pair 63. The first shift gear pair 53 and the second shift gear pair 63 have different transmission ratios, so that the output power of the first output shaft 2 is different.

[0098] As some embodiments of this application, such as Figures 1-3 , Figure 5 and Figure 6 As shown, along the axial direction of the first output shaft 2 (i.e. Figure 1 (As shown in the X direction), the first shift driven gear 61 and the second shift driven gear 62 are respectively disposed on both sides of the second coupling 72, and each of the first shift driven gear 61 and the second shift driven gear 62 has a coupling portion 73 on the side facing the second coupling 72. The second coupling 72 can selectively engage with any one of the coupling portions 73 so that the first output shaft 2 can selectively drive and connect with the first shift driven gear 61 and the second shift driven gear 62.

[0099] As some embodiments of this application, such as Figure 4 As shown, along the axial direction of the first output shaft 2 (i.e. Figure 1(As shown in the X direction), the first shift drive gear 51 and the second shift drive gear 52 are respectively disposed on both sides of the second coupling 72, and each of the first shift drive gear 51 and the second shift drive gear 52 has a coupling part 73 on the side facing the second coupling 72. The second coupling 72 can selectively engage with any one of the coupling parts 73 so that the first output shaft 2 can selectively be connected to the first shift drive gear 51 and the second shift drive gear 52 for transmission.

[0100] As some embodiments of this application, the first output shaft 2 is driven by the first shift driven gear 61 to realize the first gear in each mode, and the first output shaft 2 is driven by the second shift driven gear 62 to realize the second gear in each mode.

[0101] As some embodiments of this application, the first output shaft 2 is driven by the first shift drive gear 51 to realize the first gear in each mode, and the first output shaft 2 is driven by the second shift drive gear 52 to realize the second gear in each mode.

[0102] This configuration allows each mode of the drive assembly 100 to have two gears, which can significantly improve the vehicle's power and economy. Furthermore, by having the first shift gear pair 53 and the second shift gear pair 63 both have a engagement portion 73 on the side facing the second coupling 72, the shifting process can be quick and reliable, which is beneficial for the drive assembly 100 to flexibly switch working modes.

[0103] In some embodiments of this utility model, such as Figures 1-6 As shown, the vehicle drive assembly 100 also includes: a second motor 30 and a second output shaft 3, the second motor 30 being connected to the second output shaft 3 in a transmission manner, one of the first output shaft 2 and the second output shaft 3 being configured as a front wheel train output shaft, and the other of the first output shaft 2 and the second output shaft 3 being configured as a rear wheel train output shaft.

[0104] The second motor 30 is connected to the second output shaft 3 via a transmission connection. The transmission connection between the second motor 30 and the second output shaft 3 can be, but is not limited to, spline connection, gear pair connection, etc. As some embodiments of this application, the second motor 30 and the second output shaft 3 are connected via a gear pair connection.

[0105] One of the first output shaft 2 and the second output shaft 3 is configured as a front wheel output shaft, and the other of the first output shaft 2 and the second output shaft 3 is configured as a rear wheel output shaft. As some embodiments of this application, the first output shaft 2 is configured as a front wheel output shaft, and the second output shaft 3 is configured as a rear wheel output shaft. As some embodiments of this application, the second output shaft 3 is configured as a front wheel output shaft, and the first output shaft 2 is configured as a rear wheel output shaft.

[0106] By including a second motor 30 and a second output shaft 3 in the vehicle's drive assembly 100, and configuring one of the first output shaft 2 and the second output shaft 3 as a front wheel output shaft and the other as a rear wheel output shaft, the drive assembly 100 can be rationally configured. The vehicle can achieve four-wheel drive function with just two motors, balancing the vehicle's power performance and fuel economy, and improving the energy utilization rate of the drive assembly 100.

[0107] In some embodiments of this utility model, such as Figures 1-6 As shown, the vehicle's drive assembly 100 also includes a second transmission gear pair 90, which is drively connected between the second motor 30 and the second output shaft 3.

[0108] In other words, the second transmission gear pair 90 is disposed between the second motor 30 and the second output shaft 3, so that the second motor 30 and the second output shaft 3 are connected in a transmission manner. As some embodiments of this application, the second motor 30 has a second input shaft 31, and the second transmission gear pair 90 includes a second driving gear 91 and a second driven gear 92. The second driven gear 92 is fixed to the second output shaft 3, and the second input shaft 31 is connected in a transmission manner to the second driving gear 91. The second driving gear 91 and the second driven gear 92 mesh to form the second transmission gear pair 90, so that the second motor 30 and the second output shaft 3 are connected in a transmission manner.

[0109] The second transmission gear pair 90 can be constructed as, but is not limited to, a reduction gear pair, a speed-increasing gear pair, etc. As some embodiments of this application, the second transmission gear pair 90 is constructed as a reduction gear pair, which can achieve the effect of speed reduction and torque increase. As some embodiments of this application, the second transmission gear pair 90 is constructed as a speed-increasing gear pair, which can increase the speed of the second motor 30. As some embodiments of this application, the second transmission gear pair 90 is constructed as a gear pair with a transmission ratio of 1. It should be noted that by setting the second transmission gear pair 90, the arrangement position of the second motor 30 can be adjusted. For example, the second motor 30 can be adjusted from the side of the second output shaft 3 to the front of the second output shaft 3, thereby saving the Y-direction space of the vehicle.

[0110] This configuration enables a reliable transmission connection between the second motor 30 and the second output shaft 3, allowing for power transmission between the second motor 30 and the second output shaft 3, and also helps to save space in the drive assembly 100.

Both shift drive gears 50 are integrated into the gear ring 43, and both shift driven gears 60 are loosely fitted onto the first output shaft 2. The two shift drive gears 50 and the two shift driven gears 60 mesh one-to-one to form multiple pairs of shift gear pairs 64. The two shift gear pairs 64 have different transmission ratios. The second coupling 72 is driven by the first output shaft 2 and selectively engages with any one of the shift driven gears 60, so that the first output shaft 2 and the gear ring 43 are selectively driven by any pair of shift gear pairs 64.

[0113] As some embodiments of this application, such as Figure 2 As shown, the first coupling 70 is driven by the gear ring 43, and the first coupling 70 is selectively coupled to the sun gear 41. The first motor 20 is driven by the sun gear 41 of the planetary gear set 40. Both shift drive gears 50 are integrated into the gear ring 43, and both shift driven gears 60 are loosely fitted on the first output shaft 2. The two shift drive gears 50 and the two shift driven gears 60 mesh one-to-one to form multiple pairs of shift gear pairs 64. The two shift gear pairs 64 have different transmission ratios. The second coupling 72 is driven by the first output shaft 2, and the second coupling 72 is selectively coupled to any one of the shift driven gears 60, so that the first output shaft 2 and the gear ring 43 are selectively driven by any pair of shift gear pairs 64.

[0114] As some embodiments of this application, such as Figure 3 As shown, the first coupling 70 is driven by the drive shaft 1 and selectively engages with the sun gear 41. The first motor 20 is driven by the sun gear 41 of the planetary gear set 40. Both shift drive gears 50 are integrated into the gear ring 43.

The two shift drive gears 50 and the two shift driven gears 60 mesh one-to-one to form multiple pairs of shift gear pairs 64. The two shift gear pairs 64 have different transmission ratios. The second coupling 72 is driven by the first output shaft 2 and selectively engages with any one of the shift driven gears 60, so that the first output shaft 2 and the gear ring 43 are selectively driven by any pair of shift gear pairs 64.

[0115] As some embodiments of this application, such as Figure 4As shown, the first coupling 70 is driven by the drive shaft 1 and selectively engages with the gear ring 43. The first motor 20 is driven by the sun gear 41 of the planetary gear set 40. Both shift drive gears 50 are loosely fitted onto the gear ring 43. Both shift driven gears 60 are driven by the first output shaft 2. The two shift drive gears 50 mesh one-to-one with multiple shift driven gears 60 to form multiple pairs of shift gear pairs 64. The two shift gear pairs 64 have different transmission ratios. The second coupling 72 is driven by the gear ring 43 and selectively engages with any one of the shift drive gears 50, so that the first output shaft 2 and the gear ring 43 are selectively driven by any pair of shift gear pairs 64.

[0116] As some embodiments of this application, such as Figure 5 As shown, the first coupling 70 is driven by the drive shaft 1, selectively engages with the sun gear 41, and selectively engages with the fixed coupling 93 to lock the drive shaft 1. The first motor 20 is driven by the sun gear 41 of the planetary gear set 40. Both shift drive gears 50 are integrated into the gear ring 43, and both shift driven gears 60 are loosely fitted on the first output shaft 2. The two shift drive gears 50 and the two shift driven gears 60 mesh one-to-one to form multiple pairs of shift gear pairs 64. The two shift gear pairs 64 have different transmission ratios. The second coupling 72 is driven by the first output shaft 2, and selectively engages with any one of the shift driven gears 60 so that the first output shaft 2 and the gear ring 43 are selectively driven by any pair of shift gear pairs 64.

[0117] As some embodiments of this application, such as Figure 6 As shown, the first clutch 94 is connected between the gear ring 43 and the drive shaft 1. The gear ring 43 and the drive shaft 1 are selectively engaged through the first clutch 94. The first motor 20 is driven by the sun gear 41 of the planetary gear set 40. The two shift drive gears 50 are integrated into the gear ring 43. The two shift driven gears 60 are loosely fitted on the first output shaft 2. The two shift drive gears 50 and the two shift driven gears 60 mesh one-to-one to form multiple pairs of shift gear pairs 64. The two shift gear pairs 64 have different transmission ratios. The second coupling 72 is driven by the first output shaft 2. The second coupling 72 is selectively engaged with any one of the shift driven gears 60 so that the first output shaft 2 and the gear ring 43 are selectively driven by any pair of shift gear pairs 64.

[0118] The drive assembly 100 proposed in this application can have multiple operating modes, including but not limited to engine direct drive mode, parallel mode, power split mode, pure electric mode, and energy recovery mode. Figure 1The architecture shown is used as an example to describe the specific working states of the drive assembly 100 under various working modes.

[0119] like Figure 1 As shown, the first coupling 70 is connected to the drive shaft 1 and selectively engages with the gear ring 43. The first motor 20 is connected to the sun gear 41 of the planetary gear set 40. Both shift drive gears 50 are integrated into the gear ring 43. Both shift driven gears 60 are loosely fitted onto the first output shaft 2. The two shift drive gears 50 and the two shift driven gears 60 mesh one-to-one to form two pairs of shift gear pairs 64. The second coupling 72 is connected to the first output shaft 2 and selectively engages with any one of the shift driven gears 60, so that the first output shaft 2 and the gear ring 43 are selectively connected through any pair of shift gear pairs 64.

[0120] It is understandable that, of the two shift driven gears 60, one shift driven gear 60 is connected to the first output shaft 2 to realize the first gear in each mode, and the other shift driven gear 60 is connected to the first output shaft 2 to realize the second gear in each mode.

[0121] In engine direct drive mode, the first motor 20 does not participate in driving and is driven only by the engine 10. Engine direct drive mode can be divided into direct drive first gear mode and direct drive second gear mode.

[0122] In direct drive first gear mode, engine 10 is connected to drive shaft 1, drive shaft 1 is connected to gear ring 43, and first output shaft 2 can be connected to one of the shift driven gears 60. The power of engine 10 can be transmitted to gear ring 43 via drive shaft 1, and then to two shift drive gears 50 via gear ring 43, and then to two shift driven gears 60 via the two shift drive gears 50, and finally to the first output shaft 2 via the shift driven gear 60 connected to the first output shaft 2.

[0123] In direct drive second gear mode, engine 10 is connected to drive shaft 1, drive shaft 1 is connected to gear ring 43, and first output shaft 2 can be connected to another shift driven gear 60. The power of engine 10 can be transmitted to gear ring 43 via drive shaft 1, and then to two shift drive gears 50 via gear ring 43, and then to two shift driven gears 60 via the two shift drive gears 50, and finally to the first output shaft 2 via the shift driven gear 60 connected to the first output shaft 2.

[0124] It should be noted that the two shift gear pairs 64 have different transmission ratios, so that the power output of the direct drive first gear mode and the direct drive second gear mode are different.

[0125] In parallel mode, the engine 10 and the first motor 20 drive together. Parallel mode can be divided into parallel first gear mode and parallel second gear mode.

[0126] In the parallel first gear mode, the engine 10 is connected to the drive shaft 1, the drive shaft 1 is connected to the gear ring 43, the first output shaft 2 is connected to one of the shift driven gears 60, and the first motor 20 is connected to the sun gear 41. The power of the engine 10 is transmitted to the gear ring 43 via the drive shaft 1, the power of the first motor 20 is transmitted to the sun gear 41, and then from the sun gear 41 to the gear ring 43. The power of the first motor 20 and the engine 10 are coupled in the gear ring 43, and then transmitted from the gear ring 43 to the two shift drive gears 50, and then from the two shift drive gears 50 to the two shift driven gears 60. Finally, the power is transmitted to the first output shaft 2 through the shift driven gear 60 connected to the first output shaft 2.

[0127] In the parallel two-gear mode, the engine 10 is connected to the drive shaft 1, the drive shaft 1 is connected to the gear ring 43, the first output shaft 2 is connected to another shift driven gear 60, and the first motor 20 is connected to the sun gear 41. The power of the engine 10 is transmitted to the gear ring 43 via the drive shaft 1, the power of the first motor 20 is transmitted to the sun gear 41, and then from the sun gear 41 to the gear ring 43. The power of the first motor 20 and the engine 10 are coupled in the gear ring 43, and then transmitted from the gear ring 43 to the two shift drive gears 50, and then from the two shift drive gears 50 to the two shift driven gears 60. Finally, the power is transmitted to the first output shaft 2 through the shift driven gear 60 connected to the first output shaft 2.

[0128] It should be noted that the two shift gear pairs 64 have different transmission ratios, so that the power output of the parallel first gear mode is different from that of the parallel first gear mode.

[0129] Power shunting mode can be divided into power shunting level 1 mode and power shunting level 2 mode.

[0130] In the power split mode, the engine 10 is connected to the drive shaft 1, the drive shaft 1 is connected to the planetary carrier 42, and the first output shaft 2 can be connected to one of the shift driven gears 60. The power of the engine 10 can be transmitted to the planetary carrier 42 via the drive shaft 1. Part of the power transmitted to the planetary carrier 42 is transmitted to the sun gear 41, and then to the first motor 20 to drive the first motor 20 to generate electricity. The other part is transmitted to the ring gear 43 via the planetary carrier 42, and then to the two shift drive gears 50 via the ring gear 43. The two shift drive gears 50 are then transmitted to the two shift driven gears 60, and finally to the first output shaft 2 via the shift driven gear 60 connected to the first output shaft 2.

[0131] In the power split two-speed mode, the engine 10 is connected to the drive shaft 1, the drive shaft 1 is connected to the planetary carrier 42, and the first output shaft 2 can be connected to one of the shift driven gears 60. The power of the engine 10 can be transmitted to the planetary carrier 42 via the drive shaft 1. Part of the power transmitted to the planetary carrier 42 is transmitted to the sun gear 41, and then to the first motor 20 to drive the first motor 20 to generate electricity. The other part is transmitted to the ring gear 43 via the planetary carrier 42, and then to the two shift drive gears 50 via the ring gear 43. The two shift drive gears 50 are then transmitted to the two shift driven gears 60, and finally to the first output shaft 2 via the shift driven gear 60 connected to the first output shaft 2.

[0132] It should be noted that the two shift gear pairs 64 have different transmission ratios, so that the power output of the power split first gear mode and the power split second gear mode are different.

[0133] In pure electric mode, the engine 10 does not participate in the operation and is driven only by the first motor 20. Pure electric mode can be divided into pure electric forward first gear mode, pure electric forward second gear mode, pure electric reverse first gear mode, and pure electric reverse second gear mode.

[0134] In pure electric forward first gear mode, engine 10 is not connected to drive shaft 1. First motor 20 rotates forward. Drive shaft 1 is connected to gear ring 43. First output shaft 2 can be connected to one of the shift driven gears 60. At this time, gear ring 43 is engaged with planet carrier 42. Power of first motor 20 can be transmitted to planet carrier 42 via sun gear 41, then to gear ring 43 via planet carrier 42, and then to two shift drive gears 50 via gear ring 43. Then, the two shift drive gears 50 transmit the power to the two shift driven gears 60, and finally to the first output shaft 2 via the shift driven gear 60 connected to the first output shaft 2.

[0135] In pure electric forward second gear mode, the engine 10 is not connected to the drive shaft 1. The first motor 20 rotates forward, the drive shaft 1 is connected to the gear ring 43, and the first output shaft 2 can be connected to another shift driven gear 60. At this time, the gear ring 43 is engaged with the planet carrier 42. The power of the first motor 20 can be transmitted to the planet carrier 42 via the sun gear 41, then to the gear ring 43 via the planet carrier 42, and then to the two shift driving gears 50 via the gear ring 43. The two shift driving gears 50 then transmit the power to the two shift driven gears 60, and finally to the first output shaft 2 via the shift driven gear 60 connected to the first output shaft 2.

[0136] In pure electric reverse mode, engine 10 is not connected to drive shaft 1, first motor 20 reverses, drive shaft 1 is connected to gear ring 43, and first output shaft 2 can be connected to one of the shift driven gears 60. At this time, gear ring 43 is engaged with planet carrier 42, and the power of first motor 20 can be transmitted to planet carrier 42 via sun gear 41, then to gear ring 43 via planet carrier 42, and then to two shift drive gears 50 via gear ring 43, then to two shift driven gears 60 via the two shift drive gears 50, and finally to the first output shaft 2 via the shift driven gear 60 connected to the first output shaft 2.

[0137] In pure electric reverse second gear mode, engine 10 is not connected to drive shaft 1, first motor 20 reverses, drive shaft 1 is connected to gear ring 43, and first output shaft 2 can be connected to another shift driven gear 60. At this time, gear ring 43 is engaged with planet carrier 42, and the power of first motor 20 can be transmitted to planet carrier 42 via sun gear 41, then to gear ring 43 via planet carrier 42, and then to two shift driving gears 50 via gear ring 43, then to two shift driven gears 60 via the two shift driving gears 50, and finally to the first output shaft 2 via shift driven gear 60 connected to the first output shaft 2.

[0138] Energy recovery mode: In energy recovery mode, energy is recovered through the first motor 20 when the vehicle brakes. Energy recovery mode can be divided into energy recovery level 1 mode and energy recovery level 2 mode.

[0139] In the first energy recovery mode, the engine 10 is not connected to the drive shaft 1, the drive shaft 1 is connected to the gear ring 43, and the first output shaft 2 can be connected to one of the shift driven gears 60. At this time, the gear ring 43 is engaged with the planet carrier 42. When the vehicle brakes, the power from the wheels is transmitted through the first output shaft 2 to the shift driven gear 60 connected to the first output shaft 2, and then through the shift driven gear 60 connected to the first output shaft 2 to the shift driving gear 50 meshing with it. The shift driving gear 50 then transmits the power to the gear ring 43, and then through the gear ring 43 to the sun gear 41 via the planet carrier 42. Finally, the power is transmitted through the sun gear 41 to the first motor 20, driving the first motor 20 to generate electricity to achieve energy recovery.

[0140] In the second energy recovery mode, the engine 10 is not connected to the drive shaft 1, the drive shaft 1 is connected to the gear ring 43, and the first output shaft 2 can be connected to another shift driven gear 60. At this time, the gear ring 43 is engaged with the planetary carrier 42. When the vehicle brakes, the power from the wheels is transmitted through the first output shaft 2 to the shift driven gear 60 connected to the first output shaft 2, and then through the shift driven gear 60 connected to the first output shaft 2 to the shift driving gear 50 meshing with it. The shift driving gear 50 then transmits the power to the gear ring 43, and then through the gear ring 43 to the sun gear 41 via the planetary carrier 42. Finally, the power is transmitted through the sun gear 41 to the first motor 20, driving the first motor 20 to generate electricity and realize energy recovery.

[0141] In the series mode, the working state of the series mode is described in detail below, with the first output shaft 2 constructed as the output shaft of the front wheel train and the second output shaft 3 constructed as the output shaft of the rear wheel train.

[0142] In series mode, engine 10 is connected to drive shaft 1, drive shaft 1 is connected to gear ring 43. At this time, planet carrier 42 is engaged with gear ring 43, and first output shaft 2 is not connected to shift driven gear 60. All the power of engine 10 is transmitted to sun gear 41 through planet carrier 42, and then to first motor 20 to drive first motor 20 to generate electricity. Second motor 30 serves as the power source to drive the vehicle.

[0143] It should be noted that the second motor 30 can also perform energy recovery in the first and second energy recovery modes. Specifically, when the vehicle brakes, the power from the wheels is transmitted to the second motor 30 via the second output shaft 3 to drive the second motor 30 to generate electricity.

[0144] It should be noted that, as Figure 5The drive assembly 100 shown has an architecture in pure electric mode where the engine 10 does not participate in the operation and is driven only by the first motor 20. The pure electric mode can be divided into pure electric forward first gear mode, pure electric forward second gear mode, pure electric forward third gear mode, pure electric forward fourth gear mode, pure electric reverse first gear mode, pure electric reverse second gear mode, pure electric reverse third gear mode, and pure electric reverse fourth gear mode.
