Description

Shock absorber sleeve

Technical Field

The utility model relates to a bumper shock absorber auxiliary component technical field especially relates to a bumper shock absorber cover.

Background

The bumper shock absorber is often used for the shock mitigation system of car, and when the road surface of unevenness, the road surface of unevenness can cause jolting of car, and the existence of bumper shock absorber can effectively absorb the shock power that the lock produced of jolting for personnel's body in the car feels more comfortable. When the shock absorber is installed, its two ends are usually connected to the frame and the suspension system of the vehicle through shock absorber bushings.

The bumper shock absorber bush generally includes outer metal level, well rubber layer and the interior metal level from outside to inside, and outer metal level and interior metal level are connected with well rubber layer through vulcanizing, and in the bumper shock absorber bush use, outer metal level and interior metal level can take place sometimes and break away from with well rubber layer to cause the bumper shock absorber bush to damage unable the use, thereby cause the unable use of bumper shock absorber, and then influence the use of car.
