Description
Technical Field
[0001] The invention relates to the technical field of automobile suspension, in particular to a rubber shock absorber for automobile suspension. Background Art
[0002] Automobile suspension is an important component to ensure ride comfort. At the same time, as a force transmission device connecting the frame (or body) and the axle (or wheel), automobile suspension is also an important component to ensure automobile driving safety. Therefore, automobile suspension is often listed as an important component in the technical specification table of the automobile as one of the indicators to measure the quality of the car. During operation, rubber structure is needed to achieve shock absorption effect. Rubber shock absorber for automobile suspension is a common type of shock absorber. Its main function is to reduce the vibration and bumps of the vehicle body when the vehicle is driving, and improve the driving stability and comfort. The shock absorption effect and durability of rubber shock absorber mainly depend on the selected rubber material. Common rubber materials include natural rubber, synthetic rubber, nitrile rubber, etc. As an important part of the automobile suspension system, the design, manufacturing and quality control of rubber shock absorber need to be strictly controlled to ensure its shock absorption effect and durability, and improve the driving stability and comfort of the car.
[0003] Most of the rubber shock absorbers for automobile suspension on the market have the following problems when in use: Traditional rubber shock absorbers for automobile suspensions usually use fasteners to fix the rubber structure in actual use, and the fixing method is relatively complicated. The rubber structure needs to be disassembled for replacement or maintenance later, which is time-consuming and laborious, increasing the difficulty of disassembly. When the rubber pad of the existing rubber shock absorber for automobiles is squeezed and deformed, the stressed part sinks while other parts are not affected by the pressure, resulting in the rubber pad being not stable enough to use. At the same time, the guide pad used for guiding will be twisted when stressed because it is not restricted, so that the shock absorbing spring in the middle cannot be fully stressed, affecting the shock absorption effect, which brings certain adverse effects during use.
[0004] Therefore, it is necessary to provide a kind of rubber shock absorber for automobile suspension to solve the above-mentioned technical problems. Summary of the invention
