Abstract

The invention provides a wheel drive system which comprises an intra-wheel motor, a brake device, a wheel and tire profile measurement devices. The wheel comprises a rim and a hub disc. An inner cavity of the rim is divided by the hub disc into two cavities which do not communicate with each other. The intra-wheel motor is arranged in one cavity, and the brake device is arranged in the other cavity. The tire profile measurement devices are arranged on the side face of the wheel to measure the axial deformation of the profile of the side face of a tire, so that whether a standing wave phenomenon happens to the tire or not is identified, a driver is reminded in time to take protection measures to avoid a tire bursting accident, and the vehicle traveling safety is improved.

Description

technical field [0001] The invention relates to the technical field of chassis drive of an electric vehicle, in particular to a wheel drive system. Background technique [0002] In the prior art, the wheel drive system adopted by electric vehicles is to install the in-wheel motor directly on the wheel, and the in-wheel motor mainly includes an annular rotor, a rotor bracket, an annular stator and a stator bracket, wherein the annular rotor is installed On the rotor bracket, it is connected with the hub disk through the rotor bracket, and integrated with the wheel. Among them, the mass of the in-wheel motor is used as the unsuspended mass of the electric vehicle. [0003] With the existing technology, the mass of the in-wheel motor becomes the larger unsuspended mass of the electric vehicle. When the vehicle is running on an uneven road, the tires roll on the uneven road. Due to the large unsuspended mass above, the impact load generated by the unsuspended mass It will be v...
