The dynamic vibration absorber comprises a vibration absorber outer frame, a hub motor set is vertically connected into the vibration absorber outer frame in a sliding mode, a motor main shaft of the hub motor set stretches out of the vibration absorber outer frame to form a motor shaft stretching-out end, a transmission device is connected to the motor shaft stretching-out end, and the hub motor set is connected with the transmission device. The transmission device is connected with a steering device and wheels through a ball cage universal joint, and a distribution battery pack used for driving the hub motor set to work is connected into the vibration absorber outer frame in a sliding mode. From the perspective of optimizing the design structure, the smoothness of a vehicle driven by the hub motor is improved by fully utilizing the mass of a distributed battery and the mass of the hub motor by adopting the principle of a dynamic vibration absorber, so that the inertial load of a suspension system is reduced, the response speed and precision of the suspension system to a road surface are improved, and the vehicle driving stability is improved. And the comfort and the stability of the vehicle in the driving process are improved.
