Abstract

The utility model provides a big damping shock absorber recovers disk spring valve system for valve, which comprises a piston, the top from the top down of piston has set gradually first gasket, circulation valve stopper, second gasket, circulation valve spring, circulation valve block and third gasket, the below from the top down of piston has set gradually the fourth gasket, has recovered the throttle valve block, has recovered the valve block, has recovered valve stopper, has recovered the valve spring, has recovered valve gasket and has recovered the valve nut, the built-in piston ring of annular of piston upper end. The adjustable range of damping can be increased through the cooperation between the first gasket, the second gasket, the circulation valve spring, the circulation valve plate, the third gasket, the piston ring, the fourth gasket, the recovery throttle valve plate, the recovery valve limiter, the recovery valve spring, the recovery valve gasket and the recovery valve nut, and the adjustable range is suitable for various heavy-load trucks, so that the shock absorption function of the shock absorber is effectively improved, and meanwhile, the durability and the assembly performance are further improved.

Description

Disc spring valve system for large damping shock absorber recovery valve

Technical Field

The utility model relates to a shock absorber technical field especially relates to a big damping is belleville spring valve system for shock absorber recovery valve.

Background

The shock absorber is used for inhibiting the shock when the spring absorbs the shock and rebounds and the impact from the road surface. The damping device is widely applied to automobiles and is used for accelerating the attenuation of the vibration of a frame and an automobile body so as to improve the driving smoothness of the automobiles. When the shock absorber passes through the uneven road surface, although the shock absorbing spring can filter the shock of the road surface, the spring can still reciprocate, and the shock absorber is used for inhibiting the spring from jumping.

At present, a spring for a traditional passenger-cargo vehicle shock absorber recovery valve system is a spiral spring, the damping force value is greatly attenuated after an endurance test, and the damping function of a shock absorber is reduced, so that a disc spring valve system for a large-damping shock absorber recovery valve is provided to solve the problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a big damping is belleville spring valve system for shock absorber recovery valve aims at solving the problem that the background art provided.

In order to realize the above-mentioned purpose, the utility model discloses a big damping shock absorber is belleville spring valve system for rebound valve, which comprises a piston, the top from the top down of piston has set gradually first gasket, circulation valve stopper, second gasket, circulation valve spring, circulation valve block and third gasket, the below from the top down of piston has set gradually the fourth gasket, has recovered the throttle valve block, has recovered the valve block, has recovered valve stopper, has recovered the valve spring, has recovered valve gasket and recovered valve nut, the built-in piston ring of annular of piston upper end.

Preferably, the middle part of the flow valve plate is provided with a connecting plate, and the connecting plate is inclined downwards.

Preferably, five circular grooves in an annular array are formed in the flow valve spring.

The utility model has the advantages that:

the utility model discloses, through first gasket, second gasket, circulation valve spring, circulation valve block, third gasket, piston ring, fourth gasket, restore the throttle valve block, restore the valve stopper, restore the valve spring, restore the valve gasket and restore the adjustable scope that cooperation between the valve nut can increase damping, be applicable to various heavy load freight trains to the effectual shock-absorbing function who improves the bumper shock absorber, its durability and assemblability also further improve simultaneously.
