Vehicle double withbone arm type independent suspension system

Abstract

The invention discloses a vehicle double withbone arm type independent suspension system which comprises a front suspension assembly and a rear suspension assembly, wherein the front suspension assembly is provided with a front horizontal swinging arm assembly, the front horizontal swinging arm assembly comprises a front upper horizontal swinging arm and a front lower horizontal swinging arm, the rear suspension assembly is provided with a rear horizontal swinging arm assembly, and the rear horizontal swinging arm assembly comprises a rear upper horizontal swinging arm and a rear lower horizontal swinging arm; in the invention, the projection dimensions of the front upper horizontal swing arm and the rear upper horizontal swing arm in the transversal horizontal level respectively smaller than the projection dimensions of the front lower horizontal swing arm and the rear lower horizontal swing arm in the transversal level, the running stability of the automobile is improved, the inclinations and shakes of the vehicle body are reduced, and the lateral stiffness is high; the camber angle of a wheel can be changed automatically during the up-and-down motion, the tread changes can be reduced, the side slippage of the wheel can be avoided, and the abrasion of a tire is reduced; the vehicle double withbone arm type independent suspension system is self adaptive to road surfaces, the ground contact area of a tire is large, the grounding performance is good, and the vehicle is guaranteed to have an excellent running stability; and the left and the right wheels can jump independently and are prevented from mutual influences, the inclinations and shakes of the vehicle body are reduced, and the riding comfort is enhanced.

Description

technical field [0001] The invention relates to a vehicle suspension system, in particular to a transverse arm type independent suspension system. Background technique [0002] Suspension system is the general term for all force-transmitting connection devices between the frame of the car and the axle or wheels. The impact force of the car body and attenuate the vibration caused by it, so as to ensure the smooth running of the car. The proper function of the suspension system is to support the body and improve the riding experience. Different suspension settings will give the driver different driving experiences. Suspension system, seemingly simple in appearance, integrates various forces and determines the stability, comfort and safety of a car. It is one of the most critical components of a modern car. [0003] In the prior art, the suspension system has a variety of structures; for minicars, the front suspension is generally a MacPherson suspension, and the rear suspens...

AI Technical Summary

Problems solved by technology

The advantages of integral non-independent suspension and torsion beam semi-independent suspension are that the suspension structure is simple, the force transmission is reliable, the rear wheel track and inclination angle will not change, and the straight line stability is good; the disadvantage is that when one side of the wheel jumps, the other side The side will inevitably be affected, which will cause the body to tilt and vibrate, thus affecting driving stability and ride comfort

[0004] This shows that existing suspension system is used for miniature car, can not bring into play better technical effect
