[0079] As shown in Figure 1As shown, in some embodiments of this application, the drive assembly 10 may further include a third clutch 181. The third clutch 181 may be connected to the input shaft 141 of the engine 14, and the third clutch 181 may selectively engage the input shaft 141 with the second sun gear 151, or disengage the input shaft 141 from the second sun gear 151, or lock the second gear ring 152.

[0080] like Figure 1 As shown, in some embodiments of this application, the drive assembly 10 may further include a first housing 191. The first housing 191 may be used to house, but is not limited to, a first planetary gear set 12, a second planetary gear set 15, an engine 14, a first motor 111, a second motor 112, an output shaft 13, etc. The first housing 191 may be selectively engaged with a second clutch 17, or the first housing 191 may be selectively engaged with a third clutch 181, or the first housing 191 may be simultaneously engaged with both the second clutch 17 and the third clutch 181. The second clutch 17 may selectively engage the first gear ring 122 with the first housing 191 to lock the first gear ring 122, for example... In the pure electric high-speed second-gear mode, pure electric low-speed third-gear mode, hybrid fifth-gear mode, and ECVT second-gear mode, the second clutch 17 engages the first gear ring 122 with the first housing 191 to lock the first gear ring 122.

In these modes, the second motor 112 operates, the engine 14 does not operate, and the second motor 112 can transmit power to the drive shaft. When the output shaft 13 is disengaged from the second planetary carrier 153, the first ring gear 122 is locked or engaged with the second motor 112, for example, in pure electric high-speed second gear mode, pure electric low-speed third gear mode, hybrid fifth gear mode, and ECVT second gear mode.

When the first motor 111 is not operating... When the second motor 112 is not working, the drive assembly 10 can be in any one of the following modes: pure electric low speed second gear, pure electric low speed third gear, hybrid fourth gear, and hybrid fifth gear. When both the first motor 111 and the second motor 112 are not working, the drive assembly 10 can be in the direct drive mode of the engine 14. When both the first motor 111 and the second motor 112 are working, the drive assembly 10 can be in any one of the following modes: pure electric high speed first gear, pure electric high speed second gear, hybrid first gear, hybrid second gear, ECVT first gear, and ECVT second gear.

It can be understood that when the first motor 111 is working, the drive assembly 10 can be in hybrid three-speed mode, when the second motor 112 is working, the drive assembly 10 can be in hybrid four-speed mode or hybrid five-speed mode, and when both the first motor 111 and the second motor 112 are working, the drive assembly 10 can be in hybrid one-speed mode or hybrid two-speed mode. When the first motor 111 is working, the first clutch 16 engages or locks the first gear ring 122 with the first motor 111. It can be understood that by engaging or locking the first gear ring 122 with the first motor 111 through the first clutch 16, two output powers of the first motor 111 can be achieved. For example, the power of the first motor 111 can be transmitted to the first planetary carrier 123 and the output shaft 13 through the first gear ring 122 and the first sun gear 121, or the power of the first motor 111 can be transmitted to the first planetary carrier 123 and the output shaft 13 through the first sun gear 121.

[0084] like Figure 2As shown, in some embodiments of the present application, the drive assembly 10 can further include a second housing 192 and a fourth clutch 182, the second housing 192 can be used to accommodate, but not limited to, the first planetary set 12, the second planetary set 15, the engine 14, the first motor 111, the second motor 112, the output shaft 13, etc., the fourth clutch 182 can be connected to the second housing 192, and the fourth clutch 182 can selectively combine the second planet carrier 153 with the second housing 192 to lock the second planet carrier 153, or the fourth clutch 182 can disconnect the second planet carrier 153 from the second housing 192, and the fourth clutch 182 can also selectively combine the second sun gear 151 with the second housing 192 to lock the second sun gear 151, or disconnect the second sun gear 151 from the second housing 192, wherein the second clutch 17 can selectively combine the first ring gear 122 with the second housing 192 to lock the first ring gear 122. By providing the fourth clutch 182, the second planet carrier 153 and the second housing 192 can be selectively combined, and the second sun gear 151 and the second housing 192 can be selectively combined, so that the drive assembly can realize multiple working modes, and such a structure is simple, occupies small space, and has high integration, which is beneficial to improve the reliability of the drive assembly 10.
