Abstract
The utility model relates to a rear suspension system which comprises a rear torsion beam assembly, rear shock absorber assemblies and spiral springs, wherein the left side and the right side of the rear torsion beam assembly are respectively connected with the rear shock absorber assembly and the spiral spring; the rear torsion beam assembly is provided with spring plates, and the spiral springs are respectively arranged on the spring plates. The rear torsion beam assembly is provided with a rear shock absorber mounting bracket which is provided with two holes, wherein the hole formed in one side is fixedly provided with an inner threaded pipe, and the hole formed in the other side is provided with a connecting bolt. The rear suspension system has the beneficial effects that the system has the advantages of being high in connection strength and carrying capacity; the 'U'-shaped rear shock absorber mounting bracket is added, so that the structure is simple in processing and molding, the accuracy is easily guaranteed, and the strength, the reliability and the carrying capacity of the whole rear torsion beam assembly can be further improved. When the system is assembled in a car factory, due to the 'U'-shaped structure, lower mounting sleeves arranged at the lower ends of the rear shock absorber assemblies can be firstly blocked, the degrees of freedom along the two directions can be determined, and hole alignment assembly of the connecting bolts can be conveniently carried out.
Description
Technical field
The utility model relates to car chassis system, the rear-suspension system that especially a kind of car is used.
Background technology
Torsion girder-like rear suspension assembly, belongs to the system unit of rear overhang rack, comprises rear torsion beam assembly, coil spring and rear shock absorber assembly.In this kind of suspension, rear torsion beam assembly is substantially by crossbeam, and two longitudinal arm compositions, install a wheel on each longitudinal arm.Coil spring takes up room little, is convenient to arrange, only bears vertical power, easily obtains Nonlinear Suspension System elastic behavior, concussion when rear shock absorber assembly is mainly used to suppress rebound after spring shock-absorbing and the impact from road surface.
In arrangement, rear shock absorber assembly is arranged in the connection bracket of rear torsion beam.In the time that automobile travels on rough road surface or be subject to significant load impact, bump rubber, spring etc. produce very large axial force, act on bumper, and huge test is born at rear torsion beam assembly and vibration damper assembly connection bracket position.
Existing, with in structure, rifled pipe is separately for connecting rear shock absorber assembly., bolt, through lining under rear shock absorber, is fixed with rear torsion beam.This kind of Standard requirement is high, and difficulty.In the situation that rear shock absorber upper end has connected vehicle body, bolt need, the in the situation that of four degree of freedom, penetrate rifled pipe, and locking, is difficult to aim at assembling; As overproof in rifled pipe axial dimension, can cause cannot assembling or excessive clearance; The binding bolt adopting, need do special design, except strength grade improves, and structurally bolt tightening termination portion, needing increases anti-drop gasket, and the manufacture craft of bolt is had relatively high expectations, and cost increases.
Now use the mounting bracket of shock absorber position in torsion beam structure, intensity and durable analysis, meet the demands, but because being bolted with shock absorber support, mechanical structure is single cantilever beam structure, and the arm of force is larger, lock bolt moment is larger, easily produces distortion, even fracture.From another one angle, vibration damper assembly produces very large axial force in the time of work, and directly acts on bolt, the requirement of its intensity axial force that often out of reach bears, once and connecting portion lost efficacy, vibration damper assembly can lose support and collapse, consequence is hardly imaginable.So, be the task of top priority to the existing improvement by torsion beam and mounting bracket of shock absorber structure.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides one more firm, and load-carrying capacity and reliability are stronger, and is beneficial to the rear-suspension system that the car of vibration damper assembly dismounting and location is used.
The utility model solves the technical scheme that its technical matters adopts: the rear-suspension system that this car is used, mainly comprise rear torsion beam assembly, rear shock absorber assembly and coil spring, rear torsion beam assembly is symmetrical structure, the left and right sides is all connected with one group of rear shock absorber assembly and coil spring, rear shock absorber assembly is fixedly connected with by tie bolt with rear torsion beam assembly, rear torsion beam assembly is provided with spring holder, and coil spring is placed on spring holder.Described rear torsion beam assembly is provided with rear shock absorber mounting bracket, and rear shock absorber mounting bracket is provided with two holes, and the hole of a side is fixed with rifled pipe, and the hole of opposite side is for assembly connection bolt.
Described tie bolt, through the lower installation sleeve of rear shock absorber mounting bracket and rear shock absorber assembly lower end, lock onto in rifled pipe.
Between described rifled pipe and rear shock absorber mounting bracket, be welded to connect.
Between described rear shock absorber mounting bracket and the flange of spring holder, be welded to connect.
Described rear shock absorber mounting bracket is U-shaped structure.
The effect that the utility model is useful is: it is high that the utility model structure has Joint strenght, the advantage that bearing capacity is strong, " U " type rear shock absorber mounting bracket increasing, for high strength steel steel stamping part, machine-shaping is simple, and precision easily ensures, by being connected with the arc welding of spring holder, can further improve the intensity of overall rear torsion beam assembly, reliability and load-carrying capacity.In the time that depot assembles, because rear shock absorber assembly is first assembled with vehicle body, in the time of assembling rear overhang module, by " U " type structure, can first block the lower installation sleeve of rear shock absorber assembly lower end, determine the degree of freedom of 2 directions, be convenient to tie bolt hole is assembled.
