In the third engagement state, the drive motor 204 is adapted to drive the second wheel 208 to rotate in the second direction through the third gear 21 and the differential 206.

[0055] The differential 206 is located between the first wheel 207 and the second wheel 208. The function of the differential 206 is to allow the first wheel 207 and the second wheel 208 to rotate at different speeds, thereby achieving opposite rotation of the first wheel 207 and the second wheel 208.

That is, in this mode, the vehicle achieves the first operating mode, where engine 203 can drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0088] like Figure 23As shown, in the dual-motor drive mode, both the generator motor 205 and the drive motor 204 operate. The first clutch 13 switches to the first engaged state, the fifth clutch 169 is in the decoupled state, and the sixth clutch 43 switches to the fifth engaged state. The power generated by the generator motor 205 is transmitted to the differential 206 via the first gear 11, the first sub-gear 1701 and the second sub-gear 1702 of the sixth output gear 170, and the seventh gear 41. The power generated by the drive motor 204 is transmitted to the differential 206 via the sixth clutch 43 and the seventh gear 41. The differential 206 transmits the power from the generator motor 205 and the drive motor 204 to the first wheel 207 and the second wheel 208, causing the first wheel 207 to rotate in the first direction and the second wheel 208 to rotate in the second direction. That is, in this mode, the vehicle achieves the first operating mode, where the generator motor 205 and the drive motor 204 jointly drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0089] like Figure 24 As shown, in single-motor drive mode, only drive motor 204 operates. First clutch 13 is in neutral, fifth clutch 169 is decoupled, and sixth clutch 43 is engaged. The power generated by drive motor 204 is transmitted to differential 206 via seventh gear 41. After passing through differential 206, the power is transmitted to first wheel 207 and second wheel 208, causing first wheel 207 to rotate in a first direction and second wheel 208 to rotate in a second direction. In this mode, the vehicle achieves a first operating mode, where drive motor 204 can drive first wheel 207 and second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0090] According to some embodiments of the present invention, such as Figures 25-30 As shown, it also includes: a fifth transmission device 5, which includes: a ninth gear 51, a tenth gear 52 and a seventh clutch 53. The ninth gear 51 is adapted to drive the first wheel 207 to rotate in the first direction and / or drive the second wheel 208 to rotate in the second direction. The seventh clutch 53 has a seventh engagement state and an eighth engagement state. In the seventh engagement state, the seventh clutch 53 is engaged with the ninth gear 51, and the drive motor 204 is adapted to drive the first wheel 207 to rotate in the first direction and / or drive the second wheel 208 to rotate in the second direction through the fifth transmission device 5.

[0091] The seventh clutch 53 is located on the output shaft of the drive motor 204, while the ninth gear 51 and the tenth gear 52 are loosely fitted on the output shaft of the drive motor 204. The seventh clutch 53 is located between the ninth gear 51 and the tenth gear 52. When the seventh clutch 53 switches to the seventh engagement state, the power of the drive motor 204 is transmitted to the first wheel 207 and the second wheel 208 through the ninth gear 51, realizing the opposite rotation of the first wheel 207 and the second wheel 208.

[0092] Furthermore, such as Figure 25 As shown, it also includes: a seventh output gear 171, an eighth output gear 172, a ninth output gear 173, and an eighth clutch 174. The seventh output gear 171 is connected to the second gear 12 in a transmission connection; the eighth output gear 172 rotates synchronously with the seventh output gear 171 and is connected to the tenth gear 52 in a transmission connection; the ninth output gear 173 is adapted to drive the first wheel 207 to rotate in the first direction and / or drive the second wheel 208 to rotate in the second direction; the eighth clutch 174 is configured such that when the eighth clutch 174 is decoupled, the ninth output gear 173 is disconnected from the eighth output gear 172.

When the eighth clutch 174 is in a decoupled state, the eighth output gear 172 and the ninth output gear 173 are disconnected from the transmission connection. When the eighth clutch 174 is in a coupled state, the power of the eighth output gear 172 can be transmitted to the ninth output gear 173.

[0094] According to some embodiments of the present invention, such as Figure 25 As shown, it also includes: an engine 203, which is driven by a seventh output gear 171 and an eighth output gear 172; in the seventh engagement state, the drive motor 204 is adapted to drive the first wheel 207 to rotate in a first direction and / or drive the second wheel 208 to rotate in a second direction via the ninth gear 51; in the eighth engagement state, the drive motor 204 is adapted to be driven by the engine 203 via the tenth gear 52 and the eighth output gear 172.

[0096] The power system 100 also includes a differential 206, which is connected to a seventh sub-drive gear 2021. The first wheel 207 and the second wheel 208 are connected through the differential 206. The differential 206 distributes and transmits the power to the first wheel 207 and the second wheel 208, enabling the first wheel 207 and the second wheel 208 to rotate in opposite directions.

[0097] like Figure 26 As shown, in the hybrid series mode, the engine 203, generator 205, and drive motor 204 all operate. The first clutch 13 switches to the second engagement state, the seventh clutch 53 switches to the seventh engagement state, and the eighth clutch 174 is in the decoupled state. The power generated by the engine 203 is transmitted to the generator 205 via the seventh output gear 171 and the second gear 12, causing the generator 205 to generate electricity and supply power to the drive motor 204.

That is, in this mode, the vehicle achieves the first operating mode, and the drive motor 204 can drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0098] like Figure 27As shown, in the hybrid parallel mode, both the engine 203 and the drive motor 204 are working. The first clutch 13 is in neutral, the seventh clutch 53 is switched to the seventh engaged state, and the eighth clutch 174 is in the coupling state. The power generated by the engine 203 is transmitted to the ninth sub-drive gear 2023 via the coaxially arranged seventh output gear 171, eighth output gear 172, and ninth output gear 173, and then to the differential 206 via the third drive gear set 202. The power generated by the drive motor 204 is transmitted to the eighth sub-drive gear 2022 via the ninth gear 51, and then to the differential 206 via the third drive gear set 202. The differential 206 transmits the power from the engine 203 and the drive motor 204 to the first wheel 207 and the second wheel 208, so that the first wheel 207 rotates in the first direction and the second wheel 208 rotates in the second direction. In this mode, the vehicle operates in its first mode, where the engine 203 and the drive motor 204 jointly drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

The power generated by engine 203 is transmitted via the coaxially arranged seventh output gear 171, eighth output gear 172, and ninth output gear 173 to the ninth sub-drive gear 2023. From there, it is transmitted via the third drive gear set 202 to the differential 206, and then to the first wheel 207 and the second wheel 208, causing the first wheel 207 to rotate in a first direction and the second wheel 208 to rotate in a second direction.

The power of the drive motor 204 is transmitted to the differential 206 via the ninth gear 51, the eighth sub-transmission gear 2022, and the seventh sub-transmission gear 2021. The differential 206 transmits the power from the generator motor 205 and the drive motor 204 to the first wheel 207 and the second wheel 208, causing the first wheel 207 to rotate in the first direction and the second wheel 208 to rotate in the second direction. That is, in this mode, the vehicle achieves the first operating mode, where the generator motor 205 and the drive motor 204 jointly drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

In this mode, the vehicle achieves a first operating mode, where drive motor 204 can drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0102] According to some embodiments of the present invention, such as Figures 31-36 As shown, it also includes: a sixth transmission device 6, which includes: an eleventh gear 61, a twelfth gear 62, and a ninth clutch 63.

The tenth clutch 177 is configured such that when the tenth clutch 177 is decoupled, the tenth output gear 175 and the eleventh output gear 176 are disconnected.

[0105] Optionally, such as Figure 31 As shown, it also includes: a twelfth output gear 178 and a differential 206. The twelfth output gear 178 includes a third sub-gear 1781 and a fourth sub-gear 1782, which rotate synchronously. The third sub-gear 1781 is driven by the eleventh gear 61, and the fourth sub-gear 1782 is driven by the eleventh output gear 176. The differential 206 is driven by the fourth sub-gear 1782.

When the first clutch 13 switches to the second engagement state and the ninth clutch 63 switches to the tenth engagement state, the power of the engine 203 is transmitted to the generator motor 205, causing the generator motor 205 to generate electricity and supply power to the drive motor 204.

[0107] like Figure 32As shown, in the hybrid series mode, the engine 203, generator 205, and drive motor 204 all operate. The first clutch 13 switches to the second engagement state, the tenth clutch 177 is in the decoupled state, and the ninth clutch 63 switches to the ninth engagement state. The power of the engine 203 is transmitted to the generator 205 via the tenth output gear 175 and the second gear 12. The generator 205 generates electricity to supply power to the drive motor 204.

That is, in this mode, the vehicle achieves the first operating mode, and the drive motor 204 can drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0108] like Figure 33 As shown, in the hybrid parallel mode, both the engine 203 and the drive motor 204 are operating. The first clutch 13 is in neutral, the ninth clutch 63 is engaged, and the tenth clutch 177 is coupled. The power from the engine 203 is transmitted to the differential 206 via the tenth output gear 175, the eleventh output gear 176, and the twelfth output gear 178.

In this mode, the vehicle achieves its first operating mode, where the engine 203 and the drive motor 204 jointly drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0109] like Figure 34 As shown, in the direct drive mode of engine 203, only engine 203 operates, the first clutch 13 and the ninth clutch 63 are in neutral, and the tenth clutch 177 is engaged. The power of engine 203 is transmitted to differential 206 via the tenth output gear 175, the eleventh output gear 176, and the twelfth output gear 178, causing the first wheel 207 to rotate in the first direction and the second wheel 208 to rotate in the second direction. That is, in this mode, the vehicle achieves the first operating mode, where engine 203 can drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0110] like Figure 35As shown, in the dual-motor drive mode, both the generator motor 205 and the drive motor 204 are operational. The first clutch 13 is switched to the first engaged state, the ninth clutch 63 is switched to the ninth engaged state, and the tenth clutch 177 is in the decoupled state. The power of the generator motor 205 is transmitted to the drive motor 204 via the first gear 11 and the eleventh gear 61, and together with the power of the drive motor 204, it is transmitted to the differential 206 via the twelfth output gear 178, causing the first wheel 207 to rotate in the first direction and the second wheel 208 to rotate in the second direction. That is, in this mode, the vehicle achieves the first operating mode, where the generator motor 205 and the drive motor 204 jointly drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0111] like Figure 36 As shown, in single-motor drive mode, only drive motor 204 operates. First clutch 13 is in neutral, tenth clutch 177 is decoupled, and ninth clutch 63 is engaged. Power from drive motor 204 is transmitted to differential 206 via eleventh gear 61 and twelfth output gear 178, causing first wheel 207 to rotate in a first direction and second wheel 208 to rotate in a second direction. In this mode, the vehicle achieves its first operating mode, where drive motor 204 can drive first wheel 207 and second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0112] According to some embodiments of the present invention, such as Figures 37-41 As shown, it also includes: a seventh transmission device 7, which is connected to the drive motor 204 in a transmission manner, and the drive motor 204 is adapted to drive the second wheel 208 to rotate in a second direction through the seventh transmission device 7.

[0113] The seventh transmission device 7 includes a seventh sub-gear 71, an eighth sub-gear 72, a ninth sub-gear 73, and a tenth sub-gear 74. The seventh sub-gear 71 is located on the output shaft of the drive motor 204. The eighth sub-gear 72 and the ninth sub-gear 73 are coaxially arranged and rotate synchronously. The seventh sub-gear 71 and the eighth sub-gear 72 are connected in a transmission manner. The tenth sub-gear 74 is located on the drive half-shaft 187 of the second wheel 208. The ninth sub-gear 73 and the tenth sub-gear 74 are connected in a transmission manner.

[0114] According to some embodiments of the present invention, such as Figure 37As shown, it also includes: an eighth transmission device 8, which includes: a thirteenth gear 81, a fourteenth gear 82 and an eleventh clutch 83. The thirteenth gear 81 is adapted to be connected to the first wheel 207 for transmission; the fourteenth gear 82 is adapted to be connected to the second wheel 208 for transmission; the eleventh clutch 83 is configured such that when the eleventh clutch 83 is decoupled, the drive motor 204 drives the second wheel 208 to rotate in a second direction through the eighth transmission device 8.

[0115] As shown in the figure, the drive half-shaft 187 includes a first sub-half-shaft 1871 and a second sub-half-shaft 1872. The first sub-half-shaft 1871 is adapted to connect with the first wheel 207, and the second sub-half-shaft 1872 is adapted to connect with the second wheel 208. An eleventh clutch 83 is provided between the first sub-half-shaft 1871 and the second sub-half-shaft 1872. When the eleventh clutch 83 is in the coupled state, the first sub-half-shaft 1871 and the second sub-half-shaft 1872 are disconnected. At this time, the first wheel 207 and the second wheel 208 can be controlled separately, which is beneficial to realize that the first front wheel and the second front wheel can turn in opposite directions without interfering with each other. A thirteenth gear 81 is provided on the first sub-half-shaft 1871, and a fourteenth gear 82 and a tenth sub-gear 74 are provided on the second sub-half-shaft 1872. The thirteenth gear 81 and the fourteenth gear 82 are internally meshed.

[0116] According to some embodiments of the present invention, such as Figure 37 As shown, the power system 100 also includes: a ninth transmission device 9, and a generator motor 205 adapted to drive the first wheel 207 to rotate in a first direction via the ninth transmission device 9.

[0117] The ninth transmission device 9 includes an eleventh sub-gear 91, a twelfth sub-gear 92, a thirteenth sub-gear 93, and a fourteenth sub-gear 94. The eleventh sub-gear 91 is mounted on the output shaft of the generator motor 205. The twelfth sub-gear 92 and the thirteenth sub-gear 93 are coaxially mounted and rotate synchronously. The thirteenth sub-gear 93 and the fourteenth sub-gear 94 are connected in a transmission manner. The fourteenth sub-gear 94 is mounted on the first sub-half-shaft 1871. The thirteenth sub-gear 93 and the fourteenth sub-gear 94 are connected in a transmission manner.

[0118] According to some embodiments of the present invention, such as Figure 37 As shown, it also includes an engine 203 and a twelfth clutch 181, wherein the twelfth clutch 181 is configured such that when the twelfth clutch 181 is decoupled, the eighth transmission device 8 is adapted to disconnect the transmission connection with the engine 203.

[0119] According to some embodiments of the present invention, such as Figure 37As shown, it also includes: a thirteenth output gear 179 and a fourteenth output gear 180, with the thirteenth output gear 179 being drive-connected to the fourteenth output gear 82; the fourteenth output gear 180 is drive-connected to the thirteenth output gear 179, and when the twelfth clutch 181 is decoupled, the fourteenth output gear 180 is disconnected from the engine 203. The twelfth clutch 181 and the fourteenth output gear 180 are located on the output shaft of the engine 203, with the twelfth clutch 181 located between the engine 203 and the fourteenth output gear 180. The thirteenth output gear 179 is drive-connected to both the fourteenth output gear 180 and the fourteenth output gear 82. When the eleventh clutch 83 is decoupled, the thirteenth gear 81 and the fourteenth gear 82 are separated; when the eleventh clutch 83 is coupled, the thirteenth gear 81 and the fourteenth gear 82 are engaged.

[0120] like Figure 38 As shown, in hybrid mode, engine 203, generator 205, and drive motor 204 all operate. Eleventh clutch 83 is decoupled, while twelfth clutch 181 is coupled. At this time, the power from engine 203 is transmitted to the second sub-shaft 1872 via eleventh clutch 83, fourteenth output gear 180, thirteenth output gear 179, and fourteenth gear 82. The power from drive motor 204 is transmitted to the second sub-shaft 1872 via seventh transmission device 7, thereby driving the second wheel 208 to rotate in the second direction. The power from generator 205 is transmitted to the first sub-shaft 1871 via ninth transmission device 9, causing the first wheel 207 to rotate in the first direction. In this mode, the vehicle achieves a first operating mode, where engine 203, generator 205, and drive motor 204 jointly drive the first wheel 207 and the second wheel 208 to rotate in opposite directions, enabling the vehicle to turn in place.

[0121] like Figure 39 As shown, in the dual-motor power generation mode, the power path of the power system 100 is basically the same as that in the hybrid mode. The only difference is that in the chaotic mode, the torque vector manager on the drive half shaft 187 is disconnected, that is, the power of the drive half shaft 187 cannot be transmitted to the first wheel 207 and the second wheel 208, but the power of the drive half shaft 187 can be transmitted to the generator motor 205 and the drive motor 204 to generate electricity.

[0122] like Figure 40As shown, in the dual-motor drive mode, both the generator motor 205 and the drive motor 204 are operational, and the eleventh clutch 83 and the twelfth clutch 181 are decoupled. The power of the generator motor 205 is transmitted to the first sub-half-shaft 1871 via the ninth transmission device 9, and the power of the drive motor 204 is transmitted to the second sub-half-shaft 1872 via the seventh transmission device 7. If the generator motor 205 and the drive motor 204 rotate in the same direction, the first wheel 207 and the second wheel 208 rotate in the same direction. If the generator motor 205 and the drive motor 204 rotate in opposite directions, the first wheel 207 and the second wheel 208 rotate in opposite directions. In this case, in conjunction with the power path of the rear drive assembly in the fixed-point steering mode, the vehicle can be turned in place.

[0123] According to some embodiments of the present invention, such as Figures 41-45 As shown, it also includes: an intermediate gear 182 and a thirteenth clutch 183. The intermediate gear 182 is connected to the generator motor 205 for transmission. The intermediate gear 182 and the thirteenth clutch 183 are located on the output shaft of the engine 203. The intermediate gear 182 and the thirteenth clutch 183 are located between the twelfth clutch 181 and the fourteenth output gear 180. The intermediate gear 182 is located between the twelfth clutch 181 and the thirteenth clutch 183. The thirteenth clutch 183 is configured such that when the thirteenth clutch 183 is decoupled, the intermediate gear 182 is disconnected from the fourteenth output gear 180, and when the twelfth clutch 181 is decoupled, the engine 203 is disconnected from the intermediate gear 182.

[0124] It also includes: a fifteenth gear 184, which is located on the output shaft of the generator motor 205 and is connected to the intermediate gear 182 in a transmission manner.

[0125] like Figure 42 As shown, in the hybrid series mode, the engine 203, generator 205, and drive motor 204 all operate. The twelfth clutch 181 is coupled, and the thirteenth clutch 183 and eleventh clutch 83 are decoupled. The power from the engine 203 is transmitted to the generator 205 via the intermediate gear 182 and the fifteenth gear 184, causing the generator 205 to generate electricity to power the drive motor 204. The power from the drive motor 204 is transmitted to the first wheel 207 and the second wheel 208 via the seventh transmission device 7, causing the first wheel 207 and the second wheel 208 to rotate differentially. In other words, in this mode, the engine 203 drives the generator 205, which in turn powers the drive motor 204. The drive motor 204 then drives the first wheel 207 and the second wheel 208 to rotate differentially, achieving a flexible steering mode.

[0126] like Figure 43As shown, in the hybrid parallel mode, both the engine 203 and the drive motor 204 are working. The twelfth clutch 181 is in a coupled state, the thirteenth clutch 183 is in a coupled state, and the eleventh clutch 83 is in a decoupled state. The power of the engine 203 is transmitted to the first wheel 207 and the second wheel 208 through the intermediate gear 182, the fifteenth gear 184, the fourteenth output gear 180, the thirteenth output gear 179, the fourteenth gear 82, and the thirteenth gear 81. The power of the drive motor 204 is transmitted to the second wheel 208 through the seventh transmission device 7, so that the first wheel 207 and the second wheel 208 can rotate at different speeds. In this mode, the engine 203 and the drive motor 204 jointly drive the first wheel 207 and the second wheel 208 to rotate at different speeds. The drive motor 204 drives the first wheel 207 and the second wheel 208 to rotate at different speeds, and the engine 203 drives the first wheel 207 and the second wheel 208 to rotate at different speeds. This increases the speed difference between the first wheel 207 and the second wheel 208, enabling a flexible steering mode. If the speed difference between the first wheel 207 and the second wheel 208 is large, a stationary steering mode can be achieved. If one of the first wheel 207 and the second wheel 208 does not rotate or the relative rotation speed is small, the other wheel 207 and the other wheel 208 can rotate around the first wheel to achieve a fixed-wheel steering mode.

[0127] like Figure 44 As shown, in the direct drive mode of engine 203, only engine 203 operates, and the twelfth clutch 181, thirteenth clutch 183, and eleventh clutch 83 are all in a coupled state. The power of engine 203 is transmitted to the first wheel 207 and the second wheel 208 via the intermediate gear 182, fourteenth output gear 180, thirteenth output gear 179, fourteenth gear 82, and thirteenth gear 81, so that the first wheel 207 and the second wheel 208 rotate at a differential speed. That is, in this mode, engine 203 drives the first wheel 207 and the second wheel 208 to rotate at a differential speed, realizing a flexible steering mode.

[0128] like Figure 45As shown, in the dual-motor drive mode, both the generator motor 205 and the drive motor 204 are operational. The thirteenth clutch 183 and the eleventh clutch 83 are coupled, while the twelfth clutch 181 is decoupled. The power from the generator motor 205 is transmitted to the first wheel 207 and the second wheel 208 via the intermediate gear 182, the fourteenth output gear 180, the thirteenth output gear 179, the fourteenth gear 82, and the thirteenth gear 81. The power from the drive motor 204 is transmitted to the second wheel 208 via the seventh transmission device 7, causing the first wheel 207 and the second wheel 208 to rotate differentially. In this mode, the vehicle achieves its first operating mode, where the generator motor 205 and the drive motor 204 drive the first wheel 207 and the second wheel 208 to rotate differentially, achieving a flexible steering mode.

[0129] According to some embodiments of the present invention, such as Figure 41 As shown, it also includes: at least one torque vector manager, which is disposed between at least one of the first wheel 207 and the second wheel 208 and the seven-speed transmission.

[0130] In this embodiment, a first torque vector manager 185 and a second torque vector manager 186 are included. The first torque vector manager 185 and the second torque vector manager 186 are respectively disposed adjacent to the first wheel 207 and the second wheel 208. The first torque vector manager 185 is used to reasonably distribute and transmit the power transmitted to the first torque vector manager 185 to the first wheel 207 according to the needs of the operating conditions. The second torque vector manager 186 is used to reasonably distribute and transmit the power transmitted to the second torque vector manager 186 to the second wheel 208 according to the needs of the operating conditions, thereby realizing the rotation of the first wheel 207 and the second wheel 208.

[0132] According to the embodiments of the present invention, the vehicle's power system 100 is rationally designed so that the vehicle can improve its ability to get out of trouble and expand its usage scenarios by making reasonable use of the engine 203, drive motor 204 and generator motor 205 in the face of various complex working conditions, thereby enabling the vehicle to have more perfect performance and improve its market competitiveness.
