Description

Technical Field

[0001] The utility model relates to the field of valve plates, in particular to a pneumatic valve plate for an automobile shock absorber. Background Art

[0002] Automobile shock absorbers are mainly used to suppress the shock caused by the rebound of the spring after shock absorption and the impact from the road. They are mainly to accelerate the attenuation of the vibration of the frame and body to improve the smoothness of the car's driving. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the automobile shock absorber is used to suppress this spring jump.

[0003] The function of the automobile shock absorber valve plate is to control the control signal output by the control unit, and use power to operate to change the control elements such as flow, pressure, temperature, and liquid level. The automobile shock absorber valve plate is also called the automobile shock absorber regulating valve, which is mainly used for adjustment. The automobile shock absorber valve plate is mostly pneumatic valve plate, which generally achieves shock absorption by compressing the internal part of the shock absorber to move the internal piston.

[0004] However, when the existing pneumatic valve disc is used, it is easy for the pneumatic valve disc to be deformed under the action of air pressure. After using the pneumatic valve disc for a long time, the pneumatic valve disc is easy to be deformed, which will affect the normal use of the pneumatic valve disc and is not conducive to the use of the pneumatic valve disc.

[0005] Therefore, we propose a gas pressure valve plate for automobile shock absorber. Utility Model Content
