Abstract
The utility model discloses a kind of vibration damper valve seat, ring washer on the lower end surface that comprise valve seat body, axially run through several inner ring throttle orifices and the outer ring throttle orifice that are arranged on valve seat body, is arranged on valve seat body, described ring washer is fixedly connected with valve seat body, and the lower end surface of ring washer is sphere.When the utility model is arranged on and uses in vibration damper, lower end surface can not produce wearing and tearing, has guaranteed the performance and used life of vibration damper.
Description
Technical field
The utility model relates to a kind of vibration damper valve seat.
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 oil storage cylinder, the shock absorber piston matching with vibration damper clutch release slave cylinder in vibration damper clutch release slave cylinder outside, be arranged on the vibration damper valve seat bottom outer cylinder, the lower end surface of vibration damper valve seat contacts with the bottom surface of outer cylinder, when vibration damper is worked, vibration damper valve seat is subject to responsive to axial force, easily worn and torn in the lower end surface of vibration damper valve seat, thereby affect the performance and used life of vibration damper.
Model utility content
Technical problem to be solved in the utility model is, a kind of vibration damper valve seat is provided, and when it is arranged on and uses in vibration damper, lower end surface can not produce wearing and tearing, has guaranteed the performance and used life of vibration damper.
For solving the problems of the technologies described above, the vibration damper valve seat that the utility model provides, comprising:
Valve seat body;
Axially run through several inner ring throttle orifices and the outer ring throttle orifice that are arranged on valve seat body;
Be arranged on the ring washer on the lower end surface of valve seat body, described ring washer is fixedly connected with valve seat body, and the lower end surface of ring washer is sphere.
As preferably, described ring washer and valve seat body are adhesively fixed by glue.
As preferably, described ring washer is made by rubber material.
As preferably, the outer side wall of described valve seat body is provided with the step wall of the ring-type for coordinating with the inner cylinder tube of vibration damper, the upper-end surface of the upper end of step wall and valve seat body is connected by the inclined-plane of ring-type, and one end diameter that inclined-plane is connected to the upper-end surface with valve seat body from the one end being connected with step wall reduces gradually.
Adopt after above structure, the utility model compared with prior art, has advantages of following:
In the utility model, on the lower end surface of valve seat body, be provided with ring washer, when this vibration damper valve seat is used, ring washer contacts with the bottom surface of outer cylinder, ring washer plays buffer function, when vibration damper valve seat is subject to responsive to axial force, the lower end surface of vibration damper valve seat can not produce wearing and tearing, and ring washer can be changed after damage, thereby guaranteed the performance and used life of vibration damper, and the lower end surface of ring washer is sphere, because the bottom surface of outer cylinder is generally sphere, like this, the area of contact of the bottom surface of ring washer and outer cylinder is larger, make stressed less in unit area of ring washer, make ring washer be not easy wearing and tearing and damage.
In preferred version of the present utility model, the upper-end surface of the upper end of step wall and valve seat body is connected by the inclined-plane of ring-type, like this, by inclined-plane, just make the step wall ratio of valve seat body be easier to be pressed into inner cylinder tube, this vibration damper valve seat is installed more for convenience.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Wherein, 1, valve seat body; 101, inner ring throttle orifice; 102, outer ring throttle orifice; 103, step wall; 104, inclined-plane; 2, ring washer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model vibration damper valve seat comprises valve seat body 1.
On valve seat body 1, axially run through and be provided with several inner ring throttle orifices 101 and outer ring throttle orifice 102.
On the lower end surface of valve seat body 1, be provided with ring washer 2, described ring washer 2 is fixedly connected with valve seat body 1, and the lower end surface of ring washer 2 is sphere.
Described ring washer 2 is adhesively fixed by glue with valve seat body 1, and ring washer 2 also can be fixing by pressing with the lower end surface of valve seat body 1.
Described ring washer 2 is made by rubber material.
The outer side wall of described valve seat body 1 is provided with the step wall 103 of the ring-type for coordinating with the inner cylinder tube of vibration damper, the upper-end surface of the upper end of step wall 103 and valve seat body 1 is connected by the inclined-plane 104 of ring-type, one end diameter that inclined-plane 104 is connected to the upper-end surface with valve seat body 1 from the one end being connected with step wall 103 reduces gradually, that is to say that 104Cong lower end, inclined-plane reduces gradually to upper end diameter, the diameter of the upper end on inclined-plane 104 is less than the internal diameter of inner cylinder tube, the slightly larger in diameter of the lower end on inclined-plane 104 is in the internal diameter of inner cylinder tube, install in the process of this vibration damper valve seat, when step wall 103 is pressed into inner cylinder tube, inclined-plane 104 plays leading role, like this, step wall 103 is just pressed in inner cylinder tube than being easier to by inclined-plane 104.
Below only with regard to the utility model, apply preferably example and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various variations of doing in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
