Description

Technical Field

[0001] The utility model relates to the technical fields of automobile chassis part assembly, etc., and particularly refers to a rubber bushing installation and fixing structure for a lower control arm of a new energy vehicle. Background Technique

[0002] With the booming development of the automobile industry, the development of automobile industrial technology is also getting faster and faster. In order to reduce the development cycle and development cost, and save energy and reduce emissions, most automobile enterprises with R & D strength are currently doing technical designs for systematic development of automobile parts. The application of stamping and welding parts technology for automobile platformization and lightweighting is becoming more and more popular. The chassis system mostly uses stamping and welding parts, aluminum alloy parts, and rubber parts to replace traditional forgings and castings. At present, except for high-end models, the chassis control arms of domestic new energy vehicles basically use stamping and welding parts. Due to the use of a large number of stamping and welding parts, welding deformation and cumulative tolerances at installation points make the installation of some chassis parts relatively difficult and the disassembly is not convenient. This results in a high failure rate and high manufacturing costs. The installation mechanism of the control rubber bushing is relatively simple and is a split type. Both installation and disassembly are relatively simple. If one part is damaged, it can be replaced separately, and the maintenance cost is also low. Most rubber bushings on the market are press-fitted into the lower control arm body. Once damaged, the entire lower control arm assembly must be replaced. This structure has improved the convenience of installation and disassembly to a certain extent and reduced the maintenance cost. Content of the Utility Model
