Description
Technical field
The invention belongs to damper technical field, specially a kind of dust guard damper for having no abnormal sound wear-resisting.
Background technique
Damper is to damp material from generating for inhibiting concussion when rebounding after spring shock-absorbing and from the impact on road surface
The angular divisions of material, damper mainly have hydraulic and two kinds of inflation, and there are also a kind of damper dampers of adaptive damping and elasticity
Element carries the task of buffer and damping, and damping force is excessive, and suspension flexibility will be made to degenerate, or even damages damper connector
It is bad, thus elastic element and damper this contradiction are adjusted, damper is widely used in automobile, to accelerate vehicle frame and body vibrations
Decaying, to improve ride of vehicle, when by uneven road surface, although shock-absorbing spring can filter the shake on road surface
It is dynamic, but spring itself also has reciprocating motion, and damper is exactly for inhibiting this spring to jump.
However existing damper, firstly, structure is complicated, the abrasion sound between shock absorber structure is prolonged to wear,
The service life of the damper directly affected, and abnormal sound cannot be eliminated, and then influence user and use, secondly, existing
Damper, anti-pressure ability is lower, and then causes damper impaired serious, the service life of damper is reduced, finally, existing subtract
Device is shaken, does not have dust protection and acts on, and then influence the cleaning of damper.
