Description

Automobile shock absorber with novel dust cover

Technical Field

The utility model belongs to the technical field of automobile shock absorbers, and particularly relates to an automobile shock absorber with a novel dust cover.

Background

With the development of the times, automobiles become an indispensable part in modern life, and automobile shock absorbers are important devices in the automobile driving process, so that the shock absorbers can quickly attenuate the shock of a frame and an automobile body and improve the driving smoothness and comfort of the automobiles.

The outside of present automobile shock absorber all is provided with dust keeper, can avoid muddy water dust to get into shock absorber oil seal portion, prevents that the oil seal from becoming invalid prematurely, causes the shock absorber oil leak, and shock-absorbing function weakens or loses. The installation process of the existing dustproof device is as follows: and the dustproof cover and the buffer block are assembled into a whole and then pressed into the upper support assembly of the shock absorber.

The prior art at least has the following technical problems:

1. the existing assembly structure form has the advantages that when a vehicle runs on a distorted road surface and turns, the piston rod deflects to extrude the buffer block and the dust cover in a reciprocating mode, and the dust cover can be separated from the upper support assembly of the shock absorber.

2. The dust cover, the buffer block and the shock absorber upper support assembly can move relatively, and therefore abnormal sound is generated.

Disclosure of Invention

The utility model provides an automobile shock absorber with a novel dust cover, aiming at the problems that the piston rod in the prior art deflects and extrudes a buffer block and the dust cover in a reciprocating manner, so that the dust cover is separated from an upper support assembly of the shock absorber, and the dust cover and the buffer block and the upper support assembly of the shock absorber move relatively, so that abnormal sound occurs, and the utility model provides the automobile shock absorber with the novel dust cover, which aims to: the dust cover, the upper supporting pad and the bearing are combined into a whole, so that the problems that the dust cover falls off and abnormal sound is caused due to deflection of the piston rod in the process of twisting the road surface and steering when a vehicle runs are avoided.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides an automobile shock absorber with novel dust cover fills up on shock absorber urceolus, dust cover, bearing and the spring, the dust cover is located the periphery of shock absorber urceolus, the tip and the bearing of dust cover are connected, fill up on bearing and the spring and be connected.

Preferably, the dust cover and the bearing are assembled in a transition fit mode.

Preferably, the bearing and the dust cover are assembled and then assembled with the spring upper pad.

Preferably, the buffer block is arranged around the outer cylinder of the shock absorber of the dust cover.

Preferably, the buffer block is positioned in the dust cover.

Preferably, a gap exists between the buffer block and the dust cover.

Preferably, the spring upper pad is matched with the spring disc on the outer barrel of the shock absorber to fix the spring.

Preferably, the buffer block is fixedly connected with the outer cylinder of the shock absorber.

Compared with the prior art, the technical scheme of the utility model has the following advantages/beneficial effects:

1. the dustproof cover is combined with the upper supporting pad and the bearing into a whole, and is not assembled with the buffer block, so that the problems of falling off of the dustproof cover and abnormal sound caused by deflection of the piston rod in the process of twisting a road surface and steering of a vehicle are solved.

2. The improved dust cover has higher and stable performance, can better prevent the premature failure of the oil seal, and avoids the trouble of oil leakage of the shock absorber.
