Abstract
The utility model discloses a piston for a damper, which comprises an annular seat body. The annular seat body is provided with a piston rod mounting through hole and a throttling through hole. The throttling through hole is a snakelike through hole. Two end faces of the annular seat body are provided with retaining rings which surround the piston rod mounting through hole and are level with the hole surface of the piston mounting through hole. The ring surface of each retaining ring is provided with a plurality of projected points. The piston for the damper has the following advantages: simple structure, easy realization, and improved matching precision between the piston and an operation cylinder. The flow speed of the oil liquid can be reduced when the flow speed is overhigh for ensuring stable operation of the piston.
Description
Technical field
The utility model relates to the piston field, is specially a kind of vibration damper and uses piston.
Background technique
Concussion when vibration damper mainly is used for suppressing bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, though the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper comprises oil-overflow cylindrical shell, and disposes the piston rod that has piston that stretches in the cylindrical shell, and throttle orifice is arranged on the piston, makes that the oil in two-part space that is separated by piston can complement each other.The side face of piston ring operated by rotary motion has the leaf spring valve, and the side face of piston ring of existing technology is that face contacts with the leaf spring valve, and service time is long to be prone to cause piston and working cylinder quality of fit to reduce, and influences the damping effect of vibration damper.
The model utility content
The purpose of the utility model provides a kind of vibration damper and uses piston, with a contact replacement face contact, solves the existing technology piston long problem that is prone to cause the reduction of vibration damper damping effect service time.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of vibration damper is used piston; Include columned annular base body; It is characterized in that: have the piston rod installation through holes in the middle of the said annular base body, be arranged in annular base body and also have a plurality of throttling through holes, each throttling through hole is snakelike through hole; Said throttling through hole uniform ring is around the piston rod installation through holes; Said piston rod installation through holes two stomidium faces respectively separately correspondence be higher than the annular base body both ends of the surface, be positioned at the annular base body both ends of the surface and also be respectively arranged with around piston rod installation through holes and the back-up ring that flushes with piston rod installation through holes hole face, form a plurality of salient points on the circle face of said back-up ring.
Described a kind of vibration damper is used piston, it is characterized in that: the throttling through hole around the piston rod installation through holes has two circles, and said back-up ring is between two circle throttling through holes.
Described a kind of vibration damper is used piston, it is characterized in that: said annular base body outer side wall forms the multi-ring annular circle.
The utility model is simple in structure, is easy to realize, through on the back-up ring circle face of annular base body two ends end face, salient point being set; Can make and form point between piston and the leaf spring valve and contact; Improved the quality of fit of piston and working cylinder, and then improved the working life of vibration damper, simultaneously through the throttling via design is become snakelike; When oil flow is too fast, can reduce oil flow, guarantee that piston is stable through snakelike throttling through hole.
