Technical Field

[0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a rear suspension trailing arm subassembly platform and a use method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] During the automobile production process, some parts and components have posture, angle and position requirements when they are put on the assembly line. Controlling the initial assembly posture, angle and position can effectively solve the problems of difficulty in aligning holes, distortion, noise and tearing of parts when modular assemblies are put on the assembly line. The modular assembly of the rear suspension trailing arm subassembly includes the rear trailing arm assembly, trailing arm bracket and other assemblies, which need to be assembled and put on the assembly line with the rear subframe assembly.

[0004] In view of the current traditional vehicle assembly and manufacturing process in the automobile assembly workshop, the trailing arm and the subframe assembly are subsequently assembled online, and the trailing arm bracket and the body have assembly angle requirements. If there is a deviation in the initial angle between the trailing arm bracket and the trailing arm assembly, during the assembly of the rear suspension assembly, there will be an angle between the mounting plane of the trailing arm bracket and the mounting plane of the body, and it will be difficult to align the bolts of the trailing arm bracket during assembly, resulting in difficulty in assembling the rear suspension assembly and bolt slippage. In addition, after assembly, the rubber of the trailing arm bushing will be twisted due to the deviation in the initial angle, resulting in abnormal noise in the trailing arm or tearing of the bushing rubber during the vehicle assembly process. At present, the trailing arm assembly and the trailing arm bracket are assembled online on site, and the initial assembly angle cannot be guaranteed. Summary of the invention

Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] In view of the current traditional vehicle assembly and manufacturing process in the automobile assembly workshop, the trailing arm and the subframe assembly are subsequently assembled online, and the trailing arm bracket and the body have assembly angle requirements. If there is a deviation in the initial angle between the trailing arm bracket and the trailing arm assembly, during the assembly of the rear suspension assembly, there will be an angle between the mounting plane of the trailing arm bracket and the mounting plane of the body, and it will be difficult to align the bolts of the trailing arm bracket during assembly, resulting in difficulty in assembling the rear suspension assembly and bolt slippage. In addition, after assembly, the rubber of the trailing arm bushing will be twisted due to the deviation in the initial angle, resulting in abnormal noise in the trailing arm or tearing of the bushing rubber during the vehicle assembly process. At present, the trailing arm assembly and the trailing arm bracket are assembled online on site, and the initial assembly angle cannot be guaranteed.
