Description

Vehicle suspension system
Technical field
The utility model relates to a kind of vehicle and uses suspension, particularly a kind of wish-bone arm type independent suspension system.
Background technology
Suspension is the general name of the vehicle frame and all the power transmission connecting devices between vehicle bridge or the wheel of automobile; Its function is power and the moment of transfer function 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 that decay and cause thus, go to guarantee that automobile is smooth-going.The due function of suspension is to support vehicle body, improves the sensation of taking, and different suspension settings can make the driver that different driving experiences is arranged.Appearance seems the comprehensive multiple application force of simple suspension, is determining stability, traveling comfort and the safety of car, is one of very crucial parts of Modern Car.
In the prior art, suspension has multiple structure; For little car, front overhang generally is the MacPherson type suspension, and rear overhang generally is the suspension of integral type independent, perhaps selects the semi-independent suspension of torsion beam type for use.The MacPherson type suspension is made up of slip column and transversal swinging arm, and advantage is the space that has increased between the two-wheeled, is convenient to the layout of driving engine and other parts; Shortcoming is because the Mai Fuxun structure is too simple, causes the rigidity of suspension limited.Because Mai Fuxun suspension can only be born powerful wheel impacts power with shock absorber strut by trailing arm down, so be prone to the generation geometry deformation.This distortion embodies on the driving experience, is exactly that the driver can significantly feel the vehicle body less stable.No matter be the turning inclination, the phenomenon of nodding of still braking is all very obvious.Suspension of integral type independent and the semi-independent suspension of torsion beam type, 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 be affected inevitably, can cause vehicle body to produce and vibrations, thereby influence riding stability and travelling comfort.
This shows that existing suspension is used for minicar, can not bring into play better technical effect.Therefore, need a kind of suspension, increase the rigidity of suspension, be difficult for geometry deformation takes place, it is stable to be beneficial to the maintenance vehicle body; During use, the both sides wheel influences each other less, guarantees the levelness of vehicle body and reduces vibration, thereby guarantee riding stability and travelling comfort.
The utility model content
In view of this, the utility model provides a kind of vehicle suspension system, can not bring into play better technical effect.Therefore, need a kind of suspension, increase the rigidity of suspension, be difficult for geometry deformation takes place, it is stable to be beneficial to the maintenance vehicle body; During use, the both sides wheel influences each other less, guarantees the levelness of vehicle body and reduces vibration, thereby guarantee riding stability and travelling comfort.
The vehicle suspension system of the utility model; Comprise forward mounting assembly and rear suspension assembly; Said forward mounting assembly and rear suspension assembly are respectively about two and are oppositely arranged; Said forward mounting assembly comprises front shock absorber and preceding transversal swinging arm assembly, and said preceding transversal swinging arm assembly comprises preceding transversal swinging arm and the preceding transversal swinging arm down gone up that is set up in parallel up and down; Said rear suspension assembly comprises rear shock absorber and back transversal swinging arm assembly, said back transversal swinging arm assembly comprise be set up in parallel up and down back go up transversal swinging arm and back transversal swinging arm down.
Further, the preceding projection size of transversal swinging arm on the transverse horizontal line of going up be less than the preceding projection size of transversal swinging arm on the transverse horizontal line down, on the back transversal swinging arm at the projection size on the transverse horizontal line less than the projection size of transversal swinging arm on the transverse horizontal line under afterwards; Form not isometric double wish-bone arm type independent suspension, improved the riding stability of automobile, the inclination that reduces vehicle body and vibrations.
Further, go up transversal swinging arm before said and be connected in steering swivel top before the vehicle, preceding transversal swinging arm down is connected in steering swivel bottom before the vehicle, and transversal swinging arm is connected in steering swivel top behind the vehicle the back on, after under transversal swinging arm be connected in steering swivel bottom behind the vehicle; Simple in structure, easy installation and removal all is arranged at steering swivel, has counterbalance effect preferably.
Further, be provided with front stabilizer bar between the left and right sides forward mounting assembly, be provided with rear stabilizer bar between the rear suspension assembly of the left and right sides; Structure owing to adopting two transversal swinging arms has increased 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 owing to structural limitations; Strengthen the ability of resisting side-tipping of automobile, improve riding stability, strengthened the roll angular rigidity of automobile greatly, the inclination of vehicle body has improved riding stability when having reduced to turn.
Further, the front steering knuckle, after steering knuckles, front upper wishbone, front lower wishbone, rear upper wishbone and the rear lower control arm are made of aluminum alloy; improved suspension system response sensitivity , reducing the impact body, improving the car's Sao control and ride comfort, reduces unsprung mass and reduces body subjected to impact loads, improved handling and ride comfort.
Further; Go up transversal swinging arm, preceding transversal swinging arm down, back before said and go up transversal swinging arm under transversal swinging arm and the back and be the extend internally bending structure of the arm section and the arm section that extends back and come closer of formation, the interior extension arm section of bending structure and after extend and the hinged end of come closer arm section and vehicle frame between vertically coaxial; Go up transversal swinging arm, preceding transversal swinging arm down, back before this structure makes and go up the bigger triangular structure of transversal swinging arm formation span under transversal swinging arm and the back, rigidity and stability are increased greatly, and have enough space mounting bumper and stabilizer rod.
The beneficial effect of the utility model: the vehicle suspension system of the utility model, adopt the double wish-bone arm type independent suspension system, transverse force is absorbed by two swing arms simultaneously, and lateral stiffness is big; Wheel can change camber angle automatically and reduce tread change when up-and-down movement, avoid the wheel lateral sliding, reduces Tyte Wear; And also can the self adaptation road surface, tire-contact area is big, and it is good to paste the ground property, can guarantee that automobile has excellent traveling stability; Left and right wheels is beated separately, and is irrelevant mutually, can reduce the inclination and the vibrations of vehicle body, improves travelling comfort.
