Abstract

The invention provides a wheel driving system. The wheel driving system comprises an in-wheel motor, a braking device and a wheel, wherein the wheel comprises a rim and a hub disc, wherein the inner cavity of the rim is divided into two non-communicated chambers through the hub disc, the in-wheel motor is placed in one chamber, the braking device is placed in another chamber, an annular rotor of the in-wheel motor and a braking disc of the braking device are installed on the rim and can directly drive and brake the rim, a rotor bracket and other middle force-transfer members are omitted, a force-transfer path is shortened, the mass of the in-wheel motor is decreased, accordingly the total mass of the wheel driving system is also decreased, and the running safety and smoothness of a vehicle are further 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] Normally, the wheel drive system of an electric vehicle is equipped with a mechanical brake device, which provides the braking torque required by the vehicle together with the in-wheel motor, and is used to provide all the regenerative braking torque when the in-wheel motor cannot provide regenerative braking torque. The braking torque required to ensure the braking function and performance of the vehicle. Among them, the quality of the wheels, in-wheel motors, and braking devices constitutes the total mass of the wheel drive system. [0003] In the prior art, the annular rotor of the in-wheel motor and the brake disc of the braking device are fixed on the rotor bracket, and the rotor bracket is connected with the wheel to transmit driving force and braking force, and is used for driving and braking...
