Method for assembling multi-link suspension

Abstract

The invention provides a method for assembling a multi-link suspension. The method comprises the following steps that: in parts and components of a rear suspension assembly, besides a spiral spring (7), other parts and components can be assembled into an assembly module below-the-line; then the assembly module is suspended onto a clamp of a jacking cart; besides the spiral spring (7), other parts are assembled with the body on the right positions; a manipulator is moved to an auxiliary workbench (13) to extend a spiral spring jaw (14) into the spiral spring (7), the spiral spring (7) is compressed to a certain height L; the spiral spring (7) is placed on a position of a lower swing arm (6) through the spiral spring jaw (14); and a compressing device of the spiral spring jaw (14) is released to complete assembly of the suspension. The operation method can be observed that compared with the prior assembling method, the method has low labor intensity of staff assembly, short time stamp, and can meet the assembling requirement under a condition that the self weight of the body cannot bear that elasticity of the spring and the axes of the spring have a certain inclination angle.

Description

technical field [0001] The invention relates to the automobile industry, in particular to an assembly method of a multi-link suspension. Background technique [0002] Generally speaking, the common rear suspension structure types are: torsion beam type, trailing arm type, multi-link type. Compared with the torsion beam and trailing arm rear suspensions, the multi-link rear suspension can take into account good ride comfort and handling stability at the same time, but the assembly process is relatively complicated and takes a long time compared to the former two , It is not easy for employees to operate. Moreover, the rear coil spring needs to bear the weight of the whole vehicle and is not easy to compress. Moreover, the production line of this type of vehicle is relatively single in variety, and it is not easy to mix production with other models. [0003] Through the comparison of the assembly of this type of rear suspension in the same industry, there are mainly the foll...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the above-mentioned defects existing in the assembly of the existing multi-link suspension, and provide an assembly method of the multi-link suspension, which solves the problem of high labor intensity and time-consuming assembly of employees. Long; the assembly requirements cannot be met when the self-weight of the vehicle body cannot withstand the spring force; the assembly requirements cannot be met when the spring axis has a certain inclination angle relative to the vehicle under half-load conditions, etc.
