The invention provides an electric vehicle variable speed drive hub, and belongs to the technical field of machine engineering. The electric vehicle variable speed drive hub solves the problem that an existing electric vehicle variable speed drive hub is poor in heat dissipation performance, loud in noise and low in output efficiency. The electric vehicle variable speed drive hub comprises a fixing shaft, a hub steel ring, a motor and a speed reducer, wherein the hub steel ring is positioned on the fixing shaft; the speed reducer is located in the hub steel ring, and the motor is located on one side of the speed reducer and located outside the hub steel ring; the motor is composed of a stator and a rotor, the stator is fixedly connected with the fixing shaft, and the rotor is positioned on the fixing shaft; the speed reducer comprises a box body, an input gear shaft, an output gear shaft and an overrun clutch, the box is fixedly connected with the fixing shaft, the input gear shaft is connected with the rotor, and the output gear shaft is fixedly connected with the hub steel ring; the rotor and the hub steel ring are connected through the overrun clutch. The electric vehicle variable speed drive hub has the advantages of being good in heat dissipation effect, high in universality and low in noise.
