Abstract
The utility model relates to the technical field of shock absorbers, in particular to a piston structure of a shock absorber. The piston structure of the shock absorber comprises a piston, wherein the piston is sequentially provided with a nut, a gasket, a valve gasket, a recovery valve sheet, a throttling valve sheet and a flowing valve sheet from right to left, the gasket, the valve gasket, the recovery valve sheet and the throttling valve sheet are locked inside the piston through the nut, the flowing valve sheet is arranged at a sealed face on the left side of the piston, a reset spring is arranged between the flowing valve sheet and a piston rod, one end of the reset spring is arranged at a central force bearing point of the flowing valve sheet, and the other end of the reset spring is arranged at the right angle position of the end face of the piston rod. The piston structure of the shock absorber is reasonable in structure. As the tapered spring is arranged at the left portion of the flowing valve sheet, impact and pressing to the flowing valve sheet by hydraulic oil are reduced, resetting of the flowing valve sheet is accelerated, and the practicability is high.
Description
Technical field
The utility model relates to the vibration damper technical field, relates in particular to a kind of piston structure of shock absorber.
Background technique
Piston is one of strength member in vibration damper, piston for damper in the market is of a great variety, structure is variation also, but its working principle is substantially the same, and several main parts are wherein arranged, as circulation valve block, throttle valve plate, recovery valve block, locking nut etc., circulation valve block in present this structure is being subject to depressing than favourable opposition of liquid oil, resetting of circulation valve block is slower, affected like this work rhythm of vibration damper, thereby the efficiency of vibration damper is general.
The model utility content
The purpose of this utility model is to provide a kind of piston structure of shock absorber, and it has stamping press rational in infrastructure, as to slow down liquid oil, the valve block that makes to circulate resets fast characteristics.
For achieving the above object, the utility model adopts following technical proposals:
A kind of piston structure of shock absorber, comprise piston, on described piston, be provided with successively from right to left nut, pad, valve gasket, recovery valve block, throttle valve plate, mobile valve block, described nut lock onto pad, valve gasket, recovery valve block, throttle valve plate the inside of piston, the sealing surface on the described piston left side is provided with the circulation valve block, between described circulation valve block and piston rod, be provided with Returnning spring, one end of described Returnning spring is located at the center stressed point of circulation valve block, and the other end of described Returnning spring is located at the place, right angle of piston rod end face.
Wherein, described Returnning spring is volute spring.
Wherein, the left part of described volute spring is cone tip part.
Wherein, the right part of described volute spring is the cone bottom.
after adopting said structure, the beneficial effects of the utility model: the utility model comprises piston, on described piston, be provided with successively from right to left nut, pad, valve gasket, restore valve block, throttle valve plate, valve block flows, described nut is by pad, valve gasket, restore valve block, throttle valve plate lock onto the inside of piston, the sealing surface on the described piston left side is provided with the circulation valve block, between described circulation valve block and piston rod, be provided with Returnning spring, one end of described Returnning spring is located at the center stressed point of circulation valve block, the other end of described Returnning spring is located at the place, right angle of piston rod end face, the utility model is rational in infrastructure, by the left part at the circulation valve block, volute spring is set, thereby slow down the punching press of liquid oil to the circulation valve block, accelerate in addition resetting of circulation valve block, practical.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference character
1, Returnning spring; 2, circulation valve block;
3, piston; 4, throttle valve plate;

9, piston rod.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
as shown in Figure 1, a kind of piston structure of shock absorber, comprise piston 3, on described piston 3, be provided with successively from right to left nut 8, pad 7, valve gasket 6, restore valve block 5, throttle valve plate 4, valve block 2 flows, described nut 8 is by pad 7, valve gasket 6, restore valve block 5, throttle valve plate 4 lock onto the inside of piston 3, the sealing surface on described piston 3 left sides is provided with circulation valve block 2, between described circulation valve block 2 and piston rod 9, be provided with Returnning spring 1, one end of described Returnning spring 1 is located at the center stressed point of circulation valve block 2, the other end of described Returnning spring 1 is located at the place, right angle of piston rod 9 end faces, also can adopt between circulation valve block 2 and Returnning spring 1 and be provided with limiting board, prevent like this Returnning spring 1 scratch circulation valve block 2 at the volley.
In the present embodiment, described Returnning spring 1 is volute spring, the left part of described volute spring is cone tip part, the right part of described volute spring is the cone bottom, like this when Returnning spring 1 is under pressure, Returnning spring 1 has enough stroke spaces, also can not push and the surface of scratch circulation valve block 2 because of Returnning spring 1.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
