Device and control method for adjusting camber angle during steering of automobile

Abstract

The invention relates to a device for adjusting a camber angle when a vehicle turns and a control method thereof. The device comprises a left oil delivery pipe, a right oil delivery pipe, a left limiting block, a right limiting block, a main cylinder piston, a transverse acceleration sensor, a transverse moving linear motor, an oil fluid main cylinder, the left limiting block, the right limiting block, a left lifting piston connecting rod, a right lifting piston connecting rod, a left lifting piston, a right lifting piston, a left lifting piston tube, a right lifting piston tube, a left shock-absorbing spring, a right shock-absorbing spring, a left steering connecting rod, a right steering connecting rod, a left tube shock absorption device, a right tube shock absorption device, a left steering knuckle, a right steering knuckle, a lower left swing arm, a lower right swing arm, a lower left swing arm axis, a lower right swing arm axis, a steering small gear and a steering rack. By meansof the device, the negative camber angle of an outer side tire and the positive camber angle of an inner side tire are adjusted when the vehicle turns, the inner side abrasion of an outer side wheeland the outer side abrasion of an inner side wheel caused by the steering of the vehicle can be effectively weakened, and the service life of the tire is prolonged and the safety performance of vehicle driving is improved to prevent the occurrence of traffic accidents.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to a device for adjusting a camber angle when an automobile turns and a control method thereof. Background technique [0002] In the prior art, when the car is turning at high speed, the camber torque generated by the centrifugal force of the center of mass of the vehicle body will cause the outer suspension to compress and the inner suspension to stretch. Compression of the outboard suspension and extension of the inboard suspension not only cause body camber, but also cause increased negative camber for the outer tire and increased positive camber for the inner tire. This will increase the wear of the inner side of the outer wheel and the outer side of the inner wheel. In view of the small thickness of the tire side and no embedded steel wire, frequent wear and tear will cause a tire burst and cause a serious traffic accident. Contents of the invention [...

AI Technical Summary

Problems solved by technology

Outer suspension compression and inner suspension extension not only cause body camber, but also cause more negative camber for the outer tire and more positive camber for the inner tire

This will increase the inner wear of the outer wheel and the outer wear of the inner wheel. In view of the small thickness of the tire side and no embedded steel wire, frequent wear will lead to tire blowout and serious traffic accidents
