On the other hand, in the upper mounting structure of above-mentioned traditional bumper, support is formed by steel plastic working, casting or aluminium injection moulding.Herein, the steel plastic working of support or casting cause many restrictions of shape or the size aspect of support, make thus the weight of support very large.The aluminium injection moulding of described support obtains the support of relative light weight, but needs appreciiable material and very high tooling cost
Rear overhang rack is the general name of all load transfer devices between vehicle body and wheel, generally comprises three parts such as elastic element, shock absorber, guiding mechanism.When automobile through the road surface of jolting, impulsive force is passed to elastic element by wheel, general spring element is a big spring, the disposable macro-energy that big spring passes over wheel is impacted and is converted into repeatedly small energy impact, by shock absorber, small energy impact is repeatedly eliminated again, made vehicle body not be subject to too large vibration.Shock absorber is fixed on vehicle body by a connecting device, and what general connecting device adopted is the structure of peg type.
Main peg type connecting device comprises that one end and rear shock absorber are connected the other end through vehicle body wall body and are fixed on the bolt on vehicle body wall body by nut in the market, the part of bolt in vehicle body is arranged with successively has elastomeric upper bracket, top board and nut, and bolt part between vehicle body wall body and rear shock absorber is arranged with has elastomeric undersetting.The benefit of this connecting device is that upper and lower bearing adopts elastomeric material to make, and has again the effect of vibration damping, the vibration passing over can be reduced to minimum on shock absorber, makes vehicle body held stationary.But in the time there is enough large elastic deformation in upper and lower bearing, the axial pre tightening force of nut will significantly be reduced, friction force between nuts and bolt is not enough to fastening nuts, may get loose with bolt, cause connecting device to lose efficacy, designer has adopted double nuts to twisting for this reason, but at interior of body narrow space, assembles very inconvenient.What is more important is due to the elastic hysteresis of upper and lower bearing, while making top board and nut and separately time and near, constantly bump, produce noise.
