A rear suspension assembly installation process

Abstract

The invention discloses an installing process of a rear suspension assembly. The installing process includes the following steps that lower swing arms are placed on a subpackaging platen, then springs are placed on the lower swing arms, and an auxiliary frame is placed on the springs; the springs are compressed through a spring compression clamp; the compressed springs are kept at certain compression amount through a spring keeping clamp to be fixed between the lower swing arms and the auxiliary frame; the spring compression clamp is detached, and the rear suspension assembly is assembled on a vehicle body bottom plate; the rear suspension assembly is ejected and pressed through a rear suspension adjusting device, the springs are further compressed, the spring keeping clamp is detached, the ejecting and pressing effect of the rear suspension adjusting device on the rear suspension assembly is removed, and the springs are released to a pre-installed state. Thus, a press-fitting procedure and a combination procedure of the rear suspension assembly are split, the traditional situation that the press-fitting procedure and the combination procedure are carried out on the same station is changed, the situation that bottleneck work stations are generated in a production line body is avoided, and the production efficiency of the production line can be improved.

Description

Technical field [0001] The invention relates to the technical field of automobile rear suspension assemblies, in particular to a rear suspension assembly installation process. Background technique [0002] With the development of vehicle chassis suspension structure design, in order to pursue low-cost, high-stability, high-passability, simplification, and lightweight automotive rear suspension assemblies, more and more rear suspension assemblies are designed as multi-links. Independent rear suspension assembly. The multi-link independent rear suspension has always increased the use space of the rear luggage customers. Most of the rear shock absorber assembly and the rear coil spring are separated and placed between the lower arm of the rear suspension assembly and the subframe or body. This makes it difficult to directly assemble the rear coil spring in the traditional rear suspension assembly process. In the rear suspension assembly or rear suspension assembly assembly process,...

AI Technical Summary

Problems solved by technology

[0005] (2) In order to improve the running comfort of the vehicle, the compressible amount of the spring will be relatively large, but this special equipment is only suitable for models with a small amount of spring compression;

[0006] (3) It is only used for the rear suspension structure with a protruding mounting support under the spring. If the spring is immersed in the groove of the rear lower arm, the spring installation will not be possible.

This is because the installation support under the spring is immersed between the rear lower arm and the sub-frame installation base, so that the installation space of the rear coil spring is further reduced, that is, the space between the upper end surface of the rear lower arm and the lower end surface of the sub-frame installation base The distance cannot meet the installation space of the rear coil spring
