Power transmission structure of automobile rear shock absorber and automobile

Abstract

The invention discloses a power transmission structure of an automobile rear shock absorber and an automobile, and belongs to the field of automobiles. The power transmission structure of the automobile rear shock absorber comprises a rear-wheel cover shock absorber seat, a parcel shelf assembly which is fixed with the rear-wheel cover shock absorber seat, a C pillar lower reinforcing plate and a rear-wheel cover outside plate reinforcing plate which is fixedly connected with the rear-wheel cover shock absorber seat. Moreover, the rear-wheel cover outside plate reinforcing plate and the C pillar lower reinforcing plate are in fixed connection. According to the power transmission structure of the automobile rear shock absorber and the automobile, when the rear-wheel cover shock absorber seat is impacted, part of impact force is transmitted to the parcel shelf assembly, part of the impact force is transmitted to the C pillar lower reinforcing plate through the rear-wheel cover outside plate reinforcing plate, and then, the impact force is transmitted to a threshold of the automobile for being dispersed or being weakened. Torsional rigidity of the rear portion of the automobile is enhanced, the impact force which is transmitted to the parcel shelf assembly is also reduced, and thereby the failure probability of partial welding spots of the parcel shelf assembly is lowered, and meanwhile, abnormal sounds caused by the failure of the partial welding spots of the parcel shelf assembly are decreased as well.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile rear shock absorber force transmission structure and an automobile. Background technique [0002] When the car is running, some roads are rough or have ditches. Due to the large and unstable changes in the amplitude and frequency of the road load spectrum, although the spring and damping of the shock absorber itself will absorb most of the load transmitted by the road Load, but still part of the load is transmitted to the car through the shock absorber seat, so that the static strength or fatigue strength of the car body will appear, thus damaging the car body. [0003] At present, the force transmission structure of the automobile rear shock absorber includes a rear wheel house shock absorber seat and a package frame assembly fixed to the rear wheel house shock absorber seat; and the rear wheel house shock absorber seat is welded to the wheel house inner plate,...

AI Technical Summary

Problems solved by technology

[0004] However, in this way, the impact force received by the shock absorber seat of the rear wheel house is transmitted to the package frame through the back of the rear seat, and then transmitted to the upper body through the package frame, resulting in insufficient rigidity of the body above the package frame and cracking and failure of local welding points of the package frame problem, and the failure of local solder joints in the parcel rack assembly can easily cause abnormal noise at the rear of the car
