• a motor;
• a first shaft and a second shaft, connected with the motor in sequence;
• a gearbox;
• a right shifting fork, movable between a first position and a second position;
• a right inner ring-gear support;
• a right sun gear, a right inner planet gear, and a right outer planet gear, disposed in the right inner ring-gear support, wherein the right inner planet gear is meshed with the right sun gear;
• the right outer planet gear is meshed with both the right inner planet gear and the right inner ring-gear support;
• and the right sun gear is configured to rotate synchronously with the first shaft;
• a right planet support, connected with both the right inner planet gear and the right outer planet gear;
• a left shifting fork, movable between a third position and a fourth position;
• a left inner ring-gear support;
• a left sun gear and a left planet gear, disposed in the left inner ring-gear support, wherein the left sun gear is configured to rotate coaxially with the right inner ring-gear support;
• the left planet gear is meshed with both the left sun gear and the left inner ring-gear support;
• and the left sun gear is configured to rotate synchronously with the second shaft;
• a driving gear, configured to rotate synchronously with the left planet gear by using a left planet support;
• and
• a differential, connected with the driving gear, wherein
• when the right shifting fork is at the first position, the right planet support is connected with the gearbox;
• when the right shifting fork is at the second position, the right planet support is connected with the first shaft;
• when the left shifting fork is at the third position, the left inner ring-gear support is connected with the gearbox;
• and
• when the left shifting fork is at the fourth position, the left inner ring-gear support is connected with the second shaft.
