Description

Shock absorber shield Technical Field The utility model relates to the technical field of shock absorber equipment, in particular to a shock absorber dust cover. Background The dust cover wraps the outer cylinder of the shock absorber and the periphery of the piston rod, and forms an annular sealing structure through flexible materials such as rubber or hard shells such as metal/plastic, and is mainly used for blocking foreign matters from directly contacting the piston rod and an oil seal, guiding water flow to flow down along the outer wall of the dust cover, avoiding water from seeping into the shock absorber, scattering snow-melting agent on the road surface in saline-alkali soil or winter, isolating corrosive liquid from contacting with the metal parts of the shock absorber, and meeting bumpy road surface when a car runs, and bearing impact of a buffer block when the tire jumps up, thereby protecting the internal structure of the shock absorber. The Chinese patent document with the patent number of CN201811645911.4 discloses a dust cover assembly of a shock absorber, which comprises an upper cover and a lower cover, wherein the upper cover is in a circular shape, an annular plate for connecting the upper cover is formed at the top of the lower cover, and a through exhaust duct is formed between the upper cover and the annular plate. The utility model can effectively eliminate the exhaust noise generated during the compression of the buffer block, increase the upper cover area of the dust cover, reduce the contact pressure between the buffer block and the dust cover, effectively optimize the stress condition of the buffer block and greatly prolong the service life of the buffer block. But above-mentioned structure, when the vehicle is traveling on jolting road surface, vibrations can cause the impact of buffer block to the shield upper surface, and when buffer block and shield contact and pressurized deformation, its friction with the shield can cause abnormal sound to influence user's driving experience. Therefore, a new dust cover of the shock absorber needs to be designed for removing or greatly reducing abnormal sound generated by friction between the dust cover and the buffer block, enhancing the compression resistance and deformation resistance of the dust cover and improving the rigidity of the dust cover.
