Description
Technical field
The utility model relates to a kind of piston of vibration damper.
Background technique
The Main Function of vibration damper is when being subject to vibrations to occur relative movement between the vehicle body of Motor Vehicle and vehicle bridge or vehicle body and wheel, piston in vibration damper moves up and down, hydraulic oil in vibration damper is flowing in shock absorber oil storage cylinder through different throttle orifice from vibration damper clutch release slave cylinder repeatedly just, the now intermolecular interior friction of the friction between throttle orifice hole wall and hydraulic oil and hydraulic oil forms damping force to vibrations, make Motor Vehicle vibration energy be converted into fluid heat energy, then be dispersed in atmosphere and go by vibration damper absorption.Existing vibration damper comprises vibration damper clutch release slave cylinder, be nested with the oil storage cylinder in vibration damper clutch release slave cylinder outside, the shock absorber piston matching with vibration damper clutch release slave cylinder, be arranged on the vibration damper valve seat of clutch release slave cylinder bottom, piston is provided with by spring spacing in the check valve sheet at piston end surface, when the exterior edge face of check valve sheet is subject to the pressure of hydraulic oil, the interior edge face of check valve sheet and the end face seal of piston, and on the end face of piston, be provided with annular groove, in annular groove, be provided with the throttle orifice that several hoops distribute and axially run through piston only, when the interior edge face of check valve sheet and the end face seal of piston, check valve sheet is larger to the pressure of the end face of piston, the cell wall of annular groove is easily out of shape, will make the face deformation of piston like this, will make like this sealing effect of check valve sheet poor.
Model utility content
Technical problem to be solved in the utility model is that the piston of the vibration damper of the face deformation that can prevent piston is provided.
For solving the problems of the technologies described above, the piston of the vibration damper that the utility model provides, comprising:
Piston only;
Be arranged on the first ring connected in star on the end face of piston only, in described first ring connected in star, be provided with the first segment discharge orifice that several hoops distribute and axially run through piston only;
In described first ring connected in star, be provided with the stiffening rib that several hoops distribute, between two first segment discharge orifices of arbitrary neighborhood, a stiffening rib is set, the two ends of described stiffening rib are connected with the two side of first ring connected in star respectively, and the height of stiffening rib is all less than or equal to the degree of depth of first ring connected in star.
As preferably, the height of described stiffening rib is equal to the degree of depth of first ring connected in star.
As preferably, described first segment discharge orifice is square hole.
As preferably, the end face of described piston only is also provided with the second annular groove, and first ring connected in star, around the second annular groove setting, is provided with the second section discharge orifice that several hoops distribute and axially run through piston only in the second annular groove.
As preferably, described second section discharge orifice is circular hole.
Adopt after above structure, the utility model compared with prior art, has advantages of following:
In the utility model, several stiffening ribs are set in first ring connected in star, stiffening rib can play reinforcement effect to the cell wall of annular groove, when the interior edge face of check valve sheet is exerted pressure to the end face of piston only, owing to being provided with stiffening rib, will make the cell wall of annular groove be not easy distortion, make the sealing effect of check valve sheet better.
In preferred version of the present utility model, the height of stiffening rib is equal to the degree of depth of first ring connected in star, like this, when check valve sheet applies active force to the end face of piston only, check valve sheet directly contacts with stiffening rib, can reduce the active force of check valve sheet to the cell wall of first ring connected in star, can further prevent the cell wall distortion of annular groove, further guarantee the sealing effect of check valve sheet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, piston only; 101, first ring connected in star; 1011, first segment discharge orifice; 1012, stiffening rib; 102, the second annular groove; 1021, second section discharge orifice; 103, center hole.
