Description

Vehicle double withbone arm type independent suspension system
Technical field
The present invention relates to a kind of vehicle suspension, particularly a kind of wish-bone arm type independent suspension system.
Background technology
Suspension is the general name of all force transmission connections between the vehicle frame of automobile and vehicle bridge or wheel, its function transmits the force and moment acted between wheel and vehicle frame, and buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface, and the vibrations caused thus that decay, to ensure the smooth-going traveling of automobile.The due function of suspension supports vehicle body, and improve the sensation taken, different suspensions arranges and driver can be made to have different driving experiences.Appearance seems the comprehensive multi-acting force of simple suspension, decides the stability of car, traveling comfort and safety, is one of very crucial parts of Modern Car.
In prior art, suspension has various structures; For micro-car, front overhang is generally that MacPherson type hangs, and rear overhang is generally that integral type dependent hangs, or selects the semi-independent suspension of torsion beam type.MacPherson type hangs and is made up of slip column and transversal swinging arm, and advantage is increased the space between two-wheeled, is convenient to the layout of driving engine and other parts; Shortcoming is because Mai Fuxun structure is too simple, causes the rigidity of suspension limited.Trailing arm and shock absorber strut powerful wheel impacts power can only be born, so more easily there is geometry deformation on the lower because Mai Fuxun hangs.This distortion embodies in driving experience, is exactly that driver significantly can feel vehicle body less stable.No matter be cornering roll, or brake phenomenon of nodding, all clearly.Integral type dependent hangs and the semi-independent suspension of torsion beam type, and its advantage is that suspended structure is simple, and power transmission is reliable, and rear track, inclination angle can not change, and straight line stability is good; Shortcoming is when single wheel is beated, and opposite side also can inevitably be affected, and vehicle body can be caused to produce and vibrations, thus affect riding stability and travelling comfort.
As can be seen here, existing suspension is used for minicar, can not play good technique effect.Therefore, need a kind of suspension, increase the rigidity of suspension, not easily geometry deformation occurs, be beneficial to and keep vehicle body to stablize; During use, both sides wheel influences each other less, ensures the levelness of vehicle body and reduces vibration, thus ensureing riding stability and travelling comfort.
Summary of the invention
In view of this, the invention provides a kind of vehicle double withbone arm type independent suspension system, good technique effect can not be played.Therefore, need a kind of suspension, increase the rigidity of suspension, not easily geometry deformation occurs, be beneficial to and keep vehicle body to stablize; During use, both sides wheel influences each other less, ensures the levelness of vehicle body and reduces vibration, thus ensureing riding stability and travelling comfort.
Vehicle double withbone arm type independent suspension system of the present invention, comprise forward mounting assembly and rear suspension assembly, described forward mounting assembly and rear suspension assembly are respectively about two and are oppositely arranged, described forward mounting assembly comprises front shock absorber and front transversal swinging arm assembly, described front transversal swinging arm assembly comprises the front upper transversal swinging arm and front lower transversal swinging arm that are set up in parallel up and down, and the projection size of front upper transversal swinging arm on transverse horizontal line is less than the projection size of front lower transversal swinging arm on transverse horizontal line; Described rear suspension assembly comprises rear shock absorber and rear transversal swinging arm assembly, described rear transversal swinging arm assembly comprise be set up in parallel up and down rear upper transversal swinging arm and rear lower transversal swinging arm, the lower projection size of transversal swinging arm on transverse horizontal line after the projection size of rear upper transversal swinging arm on transverse horizontal line is less than.
Further, described front upper transversal swinging arm is connected to vehicle front steering joint top, and front lower transversal swinging arm is connected to vehicle front steering joint bottom, and rear upper transversal swinging arm is connected to vehicle rear steering joint top, and rear lower transversal swinging arm is connected to vehicle rear steering joint bottom; Structure is simple, and easy installation and removal, is all arranged at steering swivel, has good counterbalance effect.
Further, be provided with front stabilizer bar between left and right forward mounting assembly, between the rear suspension assembly of left and right, be provided with rear stabilizer bar; Owing to adopting the structure of two transversal swinging arm, add erection space, change existing minicar and only install front stabilizer bar additional, and rear suspension system does not install the structure of stabilizer rod additional due to structural limitations; Strengthen the ability of resisting side-tipping of automobile, improve riding stability, greatly strengthen the roll angular rigidity of automobile, reduce the inclination of vehicle body during turning, improve riding stability.
Further, described front steering joint, rear steering joint, front upper transversal swinging arm, front lower transversal swinging arm, rear upper transversal swinging arm and rear lower transversal swinging arm are made by aluminum alloy; Improve the response sensitivity of suspension system, reduce the impact that vehicle body is subject to, improve the Qi Che Shu property controlled and riding comfort, reduce unsprung weight, and reduce load when vehicle body is hit, improve handling and riding comfort.
Further, described front upper transversal swinging arm, front lower transversal swinging arm, rear upper transversal swinging arm and rear lower transversal swinging arm are and form the arm section and extending back and the bending structure of the arm section that comes closer of extending internally, and the interior extension arm section of bending structure and rear extension also come closer longitudinally coaxial between arm section and the hinged end of vehicle frame; This structure makes front upper transversal swinging arm, front lower transversal swinging arm, rear upper transversal swinging arm and rear lower transversal swinging arm form the larger triangular structure of span, rigidity and stability is increased greatly, and has enough space mounting bumpers and stabilizer rod.
Beneficial effect of the present invention: vehicle double withbone arm type independent suspension system of the present invention, adopt double withbone arm type independent suspension system, and front upper transversal swinging arm and the projection size of rear upper transversal swinging arm respectively on transverse horizontal line are less than front lower transversal swinging arm and the projection size of rear lower transversal swinging arm on transverse horizontal line, form Length discrepancy double wish-bone arm type independent suspension, improve the riding stability of automobile, the inclination reducing vehicle body and vibrations, transverse force is by two swing arm simultaneously stability, and lateral stiffness is large; Wheel automatically can change camber angle when up-and-down movement and reduce wheelspan change, avoids wheel lateral sliding, reduces the wearing and tearing of tire; And also can self adaptation road surface, tire-contact area is large, and it is good to paste ground property, can ensure that automobile has good riding stability; Left and right wheels is beated separately, irrelevant mutually, can reduce inclination and the vibrations of vehicle body, improves travelling comfort.
