Abstract
The invention discloses a small-friction motorcycle shock absorber. The small-friction motorcycle shock absorber comprises an oil storage cylinder, a hydraulic cylinder, a piston rod and a guide base. The hydraulic cylinder is arranged in the oil storage cylinder. The piston rod is arranged in the hydraulic cylinder in a penetrating mode and can slide relative to the hydraulic cylinder. A piston is arranged at the end of the side, located in the hydraulic cylinder, of the piston rod. A valve is arranged on the piston. The guide base is located at one end of the hydraulic cylinder. A through hole is formed in the center of the guide base. The piston rod penetrates through the through hole. The surface of the guide base and the surface of the piston rod are each wrapped with a lubricating layer. In this way, compared with an existing shock absorber, the friction force between the piston rod and the guide base of the small-friction motorcycle shock absorber is reduced, smooth fit between the piston rod and the guide base is promoted, and normal operation of a damper is effectively guaranteed.
Description
Technical field
The present invention relates to vibration damper field, particularly relate to a kind of little motorcycle vibration absorber that rubs.
Background technique
Vibration damper is the decay for accelerating vehicle frame and body vibrations, to improve the utensil of the run smoothness of vehicle.Vibration damper is primarily of a main spring and a damper composition, concussion when damper rebounds after being used for suppressing spring shock-absorbing and the impact from road surface, through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, but spring self also has to-and-fro motion, and the damper in vibration damper is just used to suppress this spring to jump.And existing motorcycle vibration absorber there will be piston rod Caton phenomenon usually, become piston rod bar and guide holder poor fit, friction is comparatively large, can not ensure that damper normally runs completely.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of little motorcycle vibration absorber that rubs, and can reduce the frictional force between piston rod and guide holder, promotes smooth cooperation between the two, effectively ensures the normal operation of damper.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of little motorcycle vibration absorber that rubs, it is characterized in that, comprise: oil storage cylinder, oil hydraulic cylinder, piston rod and guide holder, in described oil storage cylinder, described oil hydraulic cylinder is set, described piston rod to be located in oil hydraulic cylinder and can to slide relative to oil hydraulic cylinder, the end that described piston rod is positioned at oil hydraulic cylinder side is provided with a piston, described piston is provided with valve, described guide holder is positioned at end, oil hydraulic cylinder one end, guide holder center is provided with through hole, through described piston rod in through hole, wherein, described guide holder and the coated lubricating layer of piston rod surface.
In a preferred embodiment of the present invention, described lubricating layer material is Expanded graphite, and thickness is 0.5-2mm.
