COMPOSITE REDUCTION DRIVING MECHANISM

A composite reduction driving mechanism is configured to be applied to an electrical power system of an electric vehicle and to connect between an electric motor of the electrical power system and a wheel shaft. The composite reduction driving mechanism comprises a reduction gear set and a transmission band set. The reduction gear set connects a driving shaft of the electric motor. The transmission band set connects between a driven shaft of the reduction gear set and a wheel shaft. Power outputted by the electric motor is transmitted to the wheel shaft through the composite reduction driving mechanism and through two times of speed reduction during transmission, thus providing a high-torque power performance to the wheel shaft.
