Damper end cover assembly

Abstract

The invention discloses a damper end cover assembly which comprises a guider and an end cover. The end cover is a cylindrical hollow cover, at least three barbs are arranged on the end cover, the barbs are distributed along the peripheral direction of the end cover, one end of each barb is connected with the end cover, the other end of each barb extends into the end cover along the peripheral radial direction of the end cover, a plurality of grooves are arranged on the guider along the peripheral direction, and the positions and the number of the grooves correspond to the positions and the number of the barbs on the end cover. The barbs are arranged on the end cover, the barbs are pressed into the guider to hook the guider, the end cover is connected with the guider, then a damper oil cylinder is arranged, and accordingly the end cover assembly is convenient to assemble and disassemble. When the assembly is installed, a spring is in a compressed state, and a sealing ring can be directly installed at the sealing portion. When a spiral sleeve is screwed up, the sealing ring cannot move in the radial direction, and assembling sealing performance of the damper is guaranteed.

Description

technical field [0001] The invention relates to a shock absorber accessory, in particular to a shock absorber end cover assembly which is easy to assemble and disassemble and has good assembly and sealing performance. Background technique [0002] In order to facilitate disassembly and assembly of the existing gas-filled adjustable shock absorber end cap assembly, the outer circle of the end cap and the inner diameter of the shock absorber oil cylinder have a clearance fit. The outer circle of the oil cylinder is screwed so that the backing plate is pressed downwards to press the sealing ring, end cover and other parts into the oil cylinder; When the spring is in the spring state, and the step of the end cover is higher than the mouth of the oil barrel, when the screw sleeve is screwed down, the sealing ring is prone to radial movement, which will cause the sealing ring to be sheared by the oil barrel mouth and the backing plate. Damaged, destroying the sealing performance ...
