Problems solved by technology

[0002] In related technologies, power motors, transmissions, drive shafts, and axles are arranged separately, and the power is transmitted step by step. There are many transmission links, long transmission chains, low transmission efficiency, large volume, and difficult layout. In order to meet high power requirements, The volume of the power motor and transmission is usually large, and the axle bears a large torque. It is difficult to guarantee the connection strength between the axle and the transmission, and there is room for improvement
