The invention discloses a driving structure of an electric vehicle. The driving structure comprises an electric vehicle frame, a rear wheel, a middle motor and a transmission structure, the middle motor is fixed to the electric vehicle frame and located in the middle of the whole vehicle, the rear wheel is connected with the electric vehicle frame, the middle motor is connected with the rear wheel through the transmission structure, and the transmission structure comprises a driving wheel, a driven wheel and a transmission belt. The driving wheel is connected with the middle motor, the driven wheel is coaxially connected with the rear wheel, and the driving wheel is connected with the driven wheel through the transmission belt. The traditional mode that the rear wheel is directly driven by a hub motor is changed into the mode that the rear wheel is driven by the middle motor through a transmission structure, so that the effect of increasing the torque of the rear wheel can be indirectly achieved by changing the radius of the driving wheel and the radius of the driven wheel, and the driving structure has the advantages that power consumption is reduced, the driving mileage is increased, and the climbing performance of the electric vehicle is improved.
本发明公开了一种电动车的驱动结构,包括电动车车架、后轮、中置电机、传动结构,中置电机固定在电动车车架上并位于整车的中部位置,后轮与电动车车架连接,中置电机与后轮间通过传动结构进行连接,传动结构包括主动轮、从动轮、传动带,主动轮与中置电机连接,从动轮与后轮同轴连接,主动轮与从动轮通过传动带连接。本发明将传统轮毂电机直接驱动后轮改为采用中置电机通过传动结构驱动后轮,从而可以通过改变主动轮、从动轮的半径大小间接实现增大后轮扭矩的效果,使本发明具有减少耗电量、提高行驶里程、提成电动车爬坡性能的优点。
