Abstract
The utility model relates to the technical field of automotive accessories, in particular to a dust cover of a piston rod. The dust cover of the piston rod comprises a cover body, wherein an end cover plate is arranged at the upper end of the cover body, a through hole enabling the end cover plate to be matched and connected with the piston rod in a sleeved mode conveniently is formed in the middle of the end cover plate, a guiding installation structure is arranged at the bottom end of the end cover plate, the guiding installation structure comprises a sleeve arranged at the bottom end of the end cover plate in a surrounding mode, a wear-resisting layer is arranged on the inner wall of the sleeve, an installation groove is formed in the bottom end of the interior of the sleeve, and an installation plate is connected to the end cover plate. According to the dust cover of the piston rod, due to the fact that the guiding installation structure is arranged at the bottom end of the end cover plate, the dust cover can be tightly connected with the piston rod conveniently through the cooperation and connection between the guiding installation structure and the piston rod, and installation is simple and convenient. Therefore, dust can be prevented from entering the piston rod, and normal movement of the piston rod and a piston is guaranteed.
Description
Technical field
The utility model relates to the vehicle accessory technical field, relates in particular to a kind of piston rod dust-proof cover.
Background technique
Along with automotive industry, the particularly fast development of car industry, vibration damper as the important accessory of automobile, also obtained development rapidly, automobile absorber is a kind of damping member, it is one of important component of automobile suspension system, smoothness, travelling comfort, Security, steering operation and passing ability to Vehicle Driving Cycle play conclusive effect, the working principle of vibration damper is that piston lever of reducer is in the process of motion, shock absorber fluid constantly circulates by the damping hole on piston and foot valve seat, thereby is kinetic transformation that heat energy is dispersed in air.But in prior art, the piston rod of vibration damper is in movement process, can be subject to the impact of dust, and causes the slow of piston rod and piston movement or lost efficacy, therefore need to carry out proofing dust and protecting to piston rod.
