Problems solved by technology

In recent years, with the popularity of more and more high-performance cars and sports cars, high speeds have put forward more requirements on the handling stability of the suspension. Harder shock absorber adjustment can achieve faster Suspension response and sensitive handling characteristics, but when driving on uneven roads, it is easy to lose adhesion due to road excitation; softer shock absorber adjustment can make the vehicle adapt to bumpy roads, but due to the linear stiffness and angular stiffness of the suspension Low, the anti-pitch and anti-roll ability of the vehicle is poor
Since the shock absorbers of conventional suspensions provide both linear and angular stiffness to the vehicle, the two are interrelated and cannot be adjusted independently

Abstract

The invention relates to an automobile suspension system, in particular to an anti-pitching automobile suspension system. The anti-pitching automobile suspension system is formed by assembling an automobile frame, a left shock absorber, a left control arm, a left rocker arm, a left push rod, a left rotating-arm pull-push rod, a rotating arm, a T-shaped transverse stabilizing rod, a rotating-arm rotating shaft, a stabilizing-rod rotating shaft, a right shock absorber, a right control arm, a right rocker arm, a right push rod, a right rotating-arm pull-push rod and an anti-pitching shock absorber. The anti-pitching and anti-rolling properties of the anti-pitching automobile suspension system can be adjusted independently, and the anti-pitching automobile suspension system is applicable to an automobile with at least four wheels that are not located on the same line.

Description

technical field [0001] The invention relates to an automobile suspension system, in particular to an anti-pitch automobile suspension system. Background technique [0002] The traditional automobile shock absorber mainly plays the role of carrying the body and attenuating vibration, which is of decisive significance to the ride comfort of the automobile. In recent years, with the popularity of more and more high-performance cars and sports cars, high speeds have put forward more requirements on the handling stability of the suspension. Harder shock absorber adjustment can achieve faster Suspension response and sensitive handling characteristics, but when driving on uneven roads, it is easy to lose adhesion due to road excitation; softer shock absorber adjustment can make the vehicle adapt to bumpy roads, but due to the linear stiffness and angular stiffness of the suspension Low, the anti-pitch and anti-roll ability of the vehicle is poor. Since the shock absorbers of conv...
