Description
Technical Field
The invention relates to the technical field of shock absorbers, in particular to a disc spring valve system for a large-damping 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.
Disclosure of Invention
The invention aims to provide a disc spring valve system for a large-damping shock absorber recovery valve, and aims to solve the problems in the background art.
In order to achieve the purpose, the disc spring valve system for the recovery valve of the large-damping shock absorber comprises a piston, wherein a first gasket, a circulation valve limiter, a second gasket, a circulation valve spring, a circulation valve plate and a third gasket are sequentially arranged above the piston from top to bottom, a fourth gasket, a recovery throttle valve plate, a recovery valve limiter, a recovery valve spring, a recovery valve gasket and a recovery valve nut are sequentially arranged below the piston from top to bottom, and a piston ring is arranged in a ring groove in the upper end of the piston.
Preferably, the middle part of the flow valve plate is provided with a connecting plate, and the connecting plate is inclined downwards.
Preferably, the flow valve spring is provided with five circular grooves in an annular array.
The invention has the beneficial effects that:
according to the invention, the adjustable range of the damping can be increased through the matching of the first gasket, the second gasket, the flow valve spring, the flow 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 of the damping is suitable for various heavy-load trucks, so that the damping function of the shock absorber is effectively improved, and meanwhile, the durability and the assembly performance of the shock absorber are further improved.
