After the electric vehicle is provided with the pure electric speed reducer, the vehicle can better adapt to road conditions, and the speed of the vehicle can be changed in places with curves, downhill and uphill, so that the vehicle is ensured to have sufficient power to pass through.
However, the existing pure electric speed reducer is lack of a disconnecting device, and the electric motor cannot be disconnected from the differential. When the motor is an auxiliary driving motor and is used in a speed reducer and does not need auxiliary driving as power output, a disconnecting device is lacked, wheels drag the motor to rotate through a differential mechanism, and the motor can generate extra dragging torque to be used as load loss; when the vehicle speed is high, the motor easily exceeds the limit rotation speed, and loss is generated on the motor, so that the transmission efficiency is reduced, and even the motor is damaged.
