Description

Technical Field

[0001] The utility model belongs to the technical field of automotive parts, and more specifically, relates to an anti-interference component for a shock absorber. Background Art

[0002] Currently, the fixed position of the shock absorber dust cover is generally on the mounting seat or the buffer block, and it is divided into a corrugated part fixed to the lower cylinder of the shock absorber and a straight cylinder part fixed to the mounting seat or the buffer block. During the operation of the shock absorber, the lower cylinder of the shock absorber and the dust cover move relative to each other. During the movement: 1. The mounting seat is fixed to the vehicle body, and the lower end moves relative to the suspension mechanism. The movement trajectory of the shock absorber cylinder is not a linear movement and will generate a certain angle; this causes the dust cover fixed to the lower end of the buffer block to easily interfere with the lower cylinder of the shock absorber during movement. On the one hand, it generates abnormal noises, and on the other hand, it wipes off the paint layer of the lower cylinder of the shock absorber.

[0003] In the prior art, there is a technology with the name of "an anti-interference inclined groove anti-leakage structure for the shaft cavity of a shock absorber with a bushing", and the publication number is "CN203516579U". This technology is composed of an outer cylinder 1, a working cylinder 2, a piston rod 3, a guide sleeve 4, a seal 5, a compression nut 6, an oil seal 7, and an anti-wear bushing 8; its characteristics are: there is a spherical axial positioning between the guide sleeve 4 and the compression nut 6; the anti-wear bushing 8 is press-fitted into the inner hole of the guide sleeve 4, and a decompression and dirt storage groove is arranged at the right end of the inner hole of the anti-wear bushing 8; a seal 5 is arranged on the right side of the anti-wear bushing 8; the cavity between the oil seal 7 and the guide sleeve 4 is communicated with the oil storage chamber through the horizontal and vertical cross holes arranged on the guide sleeve 4 and the axial inclined grooves on the outer circle of the guide sleeve 4; in this way, the cavity between the oil seal 7 and the guide sleeve 4 is isolated from the oil storage chamber, so that the oil liquid with coarser particle impurities cannot enter this part of the cavity, reducing the wear of the piston rod 3 and the oil seal 7. During movement, the piston rod 3 can finely adjust the axis position to reduce interference.

[0004] However, this technology does not involve the technical problems and technical solutions of this application. Summary of the Utility Model
