Existing a kind of rear coil springs mounting structure as shown in Figure 2, its structure mainly comprises rubber cushion 8 and rear axle 9 under chassis runner 1, the rear coil springs seat of honour 10, rear coil springs 7, the rear coil springs.After assembling finished, the rear coil springs seat of honour 10 was pressed on the chassis runner 1 by rear coil springs 7, relied on the elastic force of rear coil springs to fix.When wheel bounce arrived the limes superiors position, rear coil springs 7 was compressed, and rear axle 9 will contact with the rear coil springs seat of honour 10 this moment, and the extruding rear coil springs seat of honour 10, made it reach compression limit, thereby reached spacing effect.Rubber cushion 8 has then been born between rear coil springs 7 and the rear axle 9 vibration isolation every the effect of making an uproar under the rear coil springs.This design plan can't be avoided rear coil springs 7 influence to 10 installation sites, the rear coil springs seat of honour in motion process, be that the rear coil springs seat of honour 10 is born isolated rear coil springs 7 and chassis runner 1 direct contact and the effect that guarantees the spacing position of rear suspension limit compression position simultaneously, thereby make 10 positions, the rear coil springs seat of honour to be affected along with the motion of rear coil springs 7, make working environment more abominable, the probability that is subjected to rear axle 9 improper bump compressions greatly improves, and finally causes the performance perameter design at the rear coil springs seat of honour 10 to be limited to, greatly reduce service life.
Summary of the invention
The purpose of this invention is to provide a kind of rear coil springs mounting structure, it can better bring into play buffering and spacing performance.
Technical scheme of the present invention is as follows:
The rear coil springs mounting structure of a kind of chassis suspension system, it comprises rubber cushion on rubber cushion under chassis runner, rear coil springs, the rear coil springs, rear axle, back bump rubber mount pad, back bump rubber and the rear coil springs.
Described back bump rubber mount pad is a bowl shaped structure, by at the bottom of its bowl by bolt below chassis runner.
The upper end of described back bump rubber is fitted in the bump rubber mount pad of back, and both fix at interference fit, and the lower end is exposed to outside the bump rubber mount pad of back.
Described rear coil springs upper end is pressed on by rubber cushion on the rear coil springs below the chassis runner, and the rear coil springs stage casing is enclosed within outside back bump rubber mount pad and the back bump rubber, and the lower end is fitted on the rear axle by rubber cushion under the rear coil springs.
This structure is when assembling, and first bump rubber mount pad afterwards above chassis runner, makes it fix with bolt; Then, the back bump rubber is squeezed in the bump rubber mount pad of back, realizes fixed installation by interference fit.In the process of wheel bob, rear coil springs does not come in contact with the back bump rubber; Rubber cushion is then born the function of isolated rear coil springs and chassis runner, rear axle direct contact respectively under rear coil springs gluing pad, the rear coil springs.
This structure makes the back bump rubber only bear buffer action, position-limiting action; and the rear coil springs rubber pad that increases between rear coil springs and chassis runner, the rear axle is used to cushion vibration and the noise that the motion of coil spring compression stretching produces; thereby improve the working environment of back bump rubber; improve its service life, evade short shortcoming of prior art rear coil springs seat of honour complex structural designs, life-span.In addition, because back bump rubber structure design has possessed higher degree of freedom in this structure, further promote and enlarged the performance curve scope of design of back bump rubber, evaded the narrow shortcoming of existing structure performance perameter scope of design, help the raising of car load rear suspension comfort property.This structure makes back bump rubber performance curve produce two sections variations in addition, helps the lifting of car load traveling comfort, and its curvilinear motion is freely compressed consistent with back bump rubber during promptly little amount of compression; But when big amount of compression, the curve when its curvilinear motion is freely compressed than back bump rubber is steeper, harder.
This structure is easy to also aspect assembling realize that because be that back bump rubber limit base arrives chassis runner by bolt, then bump rubber adopts polyurethane material, only the back bump rubber firmly need be pressed into back bump rubber mount pad during assembling and can finish general assembly.After assembling is finished, because between back bump rubber and the back bump rubber mount pad is interference fit, can well avoid it to come off and rock, back bump rubber limit base also can be controlled the deformation tendency of back bump rubber simultaneously, make its deformation curve steeper when big amount of compression, thereby further promote the car load traveling comfort.
