Abstract

The utility model discloses a bi-directional cushion valve of a shock absorber. The bi-directional cushion valve comprises a valve body (1), an upper limit cushion (2) and an upper valve plate(4) are sequentially fixed to the upper side of the valve body (1) through a locking screw (6), and a lower valve plate(5) and a lower limit cushion (3) are sequentially fixed to the lower side of the valve body (1) through the locking screw (6). An upper gap (7) is formed between the upper valve plate (4) and the valve body (1), and a lower gap (8) is formed between the lower valve plate(5) and the valve body (1). One face, connected with the corresponding valve clack, of the upper limit cushion (2) and one face, connected with the corresponding valve plate, of the lower limit cushion (3) are of an arc surface structure which is thick in center and thin in edge. The bi-directional cushion valve has the advantages of being simple in structure, rapid in response and low in designing and manufacturing cost.

Description

A kind of vibration damper two-way buffer valve

Technical field

The utility model relates to a kind of damping device in auto parts and components production field, particularly a kind of vibration damper two-way buffer valve.

Background technique

Automobile absorber is that buffering automobile jolting of being subject to that road surface, obstacle cause brings the impact of vehicle body, and it not only can protect occupant's safety and comfort, can also improve the handling of automobile.If vibration damper lost efficacy or damaged, will directly have influence on cruising characteristic and the riding comfort of automobile, also can affect the working life of auto parts and components simultaneously.

The principle of vibration damper is, when vehicle frame and vehicle bridge are done reciprocal relative movement and move back and forth in the cylinder barrel of piston at vibration damper, the fluid in vibration damper housing just flows into another inner chamber from inner chamber by some narrow holes repeatedly.Now, the interior friction of the friction of liquid and inwall and fluid molecule just forms the damping force to vibration.In vibration damper, be conventionally provided with trimmer valve, be with solving the moment buffer problem of wheel when dashing forward chance severe impact, but the timely performance of existing trimmer valve when detection wheel is subject to severe impact is inadequate, often has a very short time delay, can not detect in time and damping, affect damping effect; And the complicated structure of existing trimmer valve, fabricating cost is high.

Summary of the invention

For the defect existing in existing vibration damper, the utility model provides a kind of vibration damper two-way buffer valve.

To achieve these goals, technical solution adopted in the utility model is:

A kind of vibration damper two-way buffer valve, comprise valve body, the upside of valve body is fixed with upper limit pad and upper valve block successively by locking rivet, the downside of valve body is fixed with and lower valve and lower limit pad successively by locking rivet, between upper valve block and valve body, be provided with gap, between lower valve and valve body, be provided with lower gap, one side that upper limit pad is connected with valve block with lower limit pad all centered by the thin globoidal structure of thick rim;

He Xia gap, described upper gap is interior narrow outer wide annular space;

The material of described upper valve block and lower valve is spring steel.

The beneficial effects of the utility model: can moment wheel be detected and be subject to severe impact, for vehicle suspension provides buffering accurately, be swift in response; Simple in structure, design and manufacture is with low cost.

Fig. 1, structural representation of the present utility model.

Embodiment

A kind of vibration damper two-way buffer valve, comprise valve body 1, the upside of valve body 1 is fixed with upper limit pad 2 and upper valve block 4 successively by locking rivet 6, the downside of valve body 1 is fixed with and lower valve 5 and lower limit pad 3 successively by locking rivet 6, between upper valve block 4 and valve body 1, be provided with gap 7, between lower valve 5 and valve body 1, be provided with lower gap 8, one side that upper limit pad 2 is connected with valve block with lower limit pad 3 all centered by the thin globoidal structure of thick rim; Described upper gap 7 and lower gap 8 are interior narrow outer wide annular space; The material of described upper valve block 4 and lower valve 5 is spring steel.

Working principle of the present utility model: when wheel is when being subject to severe impact, the movement velocity of shock absorber piston can improve thereupon, the oil flow of this valve annular space of now flowing through can change suddenly equally, therefore there is change in the fluid pressure of the upper and lower both sides of valve block, when this change reaches predefined value, will there is resiliently deformable and then annular space is closed in valve block, reach the object of moment detection.

The simple replacement of those ordinary skill in the art and replacing are all within this patent protection domain.
