Electric wheel system integrating shock absorption and power generation, working method thereof, and vehicle

Abstract

The invention provides an electric wheel system integrating shock absorption and power generation, a working method thereof, and a vehicle. The electric wheel system comprises a wheel, a driving motor, a wheel shock absorber and a main shock absorber, and the main shock absorber is fixedly connected with a fixed part of the driving motor through an axle and is used for fixing and supporting the driving motor; and the rotating part of the driving motor is connected with wheel steel ring of the wheel through the wheel shock absorber and is used for transmitting driving force of the driving motorto the wheel through the wheel shock absorber. The five functions of driving, shock absorption, power generation, braking and damping adjustment are integrated, rigid connection between the wheel andthe driving motor is changed into flexible connection, secondary shock absorption is increased, the controllability and comfort of the vehicle are further improved, meanwhile, the unsprung mass is reduced, and vibration impact borne by the motor is reduced.

Description

technical field [0001] The present disclosure relates to the technical field related to the electric wheel system, and in particular, relates to an electric wheel system integrating shock absorption and power generation, a working method and a vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The electric wheel is to directly install the drive motor inside the wheel, and directly drive the wheel through the motor, also known as hub motor technology. Because transmission components such as the engine, gearbox, clutch, and transmission shaft of the original fuel vehicle are omitted, the vehicle structure is simplified. However, since the motor is directly installed with the wheel, the mass of the motor is increased on the basis of the original wheel, resulting in a significant increase in the mass of the new wheel system, which bri...

AI Technical Summary

Problems solved by technology

However, since the motor is directly installed with the wheel, the mass of the motor is increased on the basis of the original wheel, resulting in a significant increase in the mass of the new wheel system, which brings a series of problems:

[0004] 1. Although the quality of the vehicle is greatly reduced, the mass below the shock absorber of the vehicle, referred to as the unsprung mass, that is, the mass of the wheel is greatly increased, which will adversely affect the handling, comfort and suspension reliability of the vehicle

[0005] 2. Fix the precision motor to the wheel hub. The vibration shock of the wheel caused by the uneven road surface is easily transmitted to the motor itself through the wheel hub, so that the motor will be subjected to severe vibration up and down with the wheel for a long time and harsh working environments such as water and dust. Resulting in reduced motor reliability
