Abstract
The utility model discloses a rebuilt valve of a shock absorber, comprising a check block, a circulation valve, a piston, a normal open valve plate, a throttle valve plate, an inner gasket, an outer gasket, a piston nut and a spring guide gasket, wherein an annular bulge is arranged at the periphery of the spring guide gasket and is pressed on the throttle valve plate, the spring guide gasket is sheathed outside the outer gasket, and the spring guide gasket is connected with a spring which is sheathed on the piston nut. By adopting the structure, the rebuilt valve has the advantages that the spring can reduce the impact of oil to a great extent, thereby preventing the valve plate from being broken, and force values can be adjusted conveniently.
Description
Technical field
The utility model relates to the vehicle vibration damping technical field, particularly a kind of vibration damper rebuilt valve.
Background technique
Vibration damper uses for the vibrations of eliminating road surface input and bringing.Vibration damper inner valve architecture because of there being the inadequate natural endowment of design on the structure, causes vibration damper to produce damping force instability and smooth at present, and noise is bigger; Between low velocity zone with high velocity between damping force produce and governing factor different, cause damping force between low velocity zone and between high velocity to change and have discontinuity; The valve sensitivity is poor during working at high speed; And easily produce damping force and scatter; Simultaneously, under high-speed case, valve block is done the torsional deformation work of high frequency and big amplitude under the impact of fluid, and the shock-resistant and fatigue performance of valve plate material is had quite high requirement, and generally valve block is subject to excess impact and ruptures.
The model utility content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of vibration damper rebuilt valve of avoiding valve block because of impact fracture.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of vibration damper rebuilt valve, comprise block, flowing valve, piston, normally open valve sheet, throttle valve plate, internal gasket, outer pad, piston unt, described vibration damper rebuilt valve also comprises spring guiding pad, the periphery of described spring guiding pad is provided with annular protrusion, described annular protrusion is pressed on the described throttle valve plate, described spring guiding pad is socketed in outside the described outer pad, described spring guiding pad is connected with spring, and described spring housing is connected on the piston unt.
Described spring one end is connected with spring guiding pad, and the other end is connected on the bolt interior edge face of piston unt.
The external diameter of described outer pad is less than the internal diameter of spring guiding pad.
The utility model adopts said structure, and have the following advantages: 1, spring can reduce the impact force of fluid to a great extent, avoids the valve block fracture; 2, can make things convenient for the power value to regulate.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a decomposition texture schematic representation of the present utility model;
Fig. 2 is a package assembly schematic representation of the present utility model;
In Fig. 1～Fig. 2,1, block; 2, flowing valve; 3, piston; 4, normally open valve sheet; 5, throttle valve plate; 6, internal gasket; 7, outer pad; 8, piston unt; 9, spring guiding pad; 10, spring.
Embodiment
As Fig. 1～a kind of vibration damper rebuilt valve shown in Figure 2, comprise block 1, flowing valve 2, piston 3, normally open valve sheet 4, throttle valve plate 5, internal gasket 6, outer pad 7, piston unt 8, the vibration damper rebuilt valve also comprises spring guiding pad 9, the periphery of spring guiding pad 9 is provided with annular protrusion, annular protrusion is pressed on the described throttle valve plate, spring guiding pad 9 is socketed in outside the described outer pad 7, and spring guiding pad 9 is connected with spring 10, and spring 10 is socketed on the piston unt 8.Spring 10 1 ends are connected with spring guiding pad 9, and the other end is connected on the bolt interior edge face of piston unt 8.The external diameter of outer pad 7 is less than the internal diameter of spring guiding pad 9.Under high-speed case, valve block plays the effect of alleviation at the impact lower spring 10 of fluid, can avoid valve block to rupture because of impact.
By the trickle adjustment of multi-faceted change part, just can obtain has different damping forces under the different speed.For example, the damping force value under the low speed situation of change can change breach size, the quantity of throttle valve plate and the thickness of valve block; Change external diameter, thickness and the quantity of pad, change the damping force value; Simultaneously, parts design can seriation, to adjusting the scope and the degree of accuracy of damping force, very large facility is arranged; To Products Development, quick in the adjustment of power value, accurate.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted the technical solution of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
