Abstract

The invention relates to an electric wheel which comprises a rim, a wheel carrier, a damping mechanism, a motor and a parallel eccentric coupler. The wheel carrier is rotationally arranged on the inner ring of the rim. The damping mechanism is arranged on the wheel carrier. The motor is arranged on the damping mechanism, and the damping mechanism allows the motor to generate displacement within aset range in the vertical direction of the use state. The parallel eccentric coupler is arranged between the output end of the motor and the rim, the eccentric distance of the parallel eccentric coupler is variable within a set range, and the parallel eccentric coupler can be eccentric in the vertical direction of the use state. The invention further provides an automobile chassis comprising the electric wheel and a new energy automobile. According to the electric wheel, the automobile chassis and the new energy automobile, the vertical vibration of the motor and the transmission of the driving torque are decoupled through the synergistic effect of the damping mechanism and the parallel eccentric coupler, so that the air gap change of the stator and the rotor in the motor is reduced, the impact load of a road surface on the motor is relieved, and the service life of the motor is prolonged.

Description

Technical field[0001]The present invention relates to the technical field of vehicles, in particular to electric wheels, automobile chassis and new energy vehicles.Background technique[0002]With the continuous advancement of technology, new energy vehicles have gradually entered people's lives and become popular. Different from traditional automobile wheels, electric wheels in new energy vehicles are a new type of driving technology that directly arranges motors in the wheels for driving. This greatly reduces the quality of the transmission system, is conducive to the lightweight of the car, and expands the design space of the body. In addition, due to the short transmission chain, the transmission efficiency is high and the response of the driving force is faster. The other four wheels can be driven and controlled independently, which greatly improves the dynamic performance of the car and improves the power and safety of the car. However, because the motor is installed in the whee...
