Abstract
The utility model relates to the field of valves, and provides a two-stage valve mechanism of a single-cylinder shock absorber. The two-stage valve mechanism of the single-cylinder shock absorber comprises a connecting rod, a limiting piece, a first valve piece, a spring piece, a two-stage valve piece, a piston, an adjusting shim, a second valve piece, a valve body, a locking shim and a locking nut. The connecting rod is sequentially sleeved with the limiting piece, the first valve piece, the spring piece, the two-stage valve piece, the piston, the adjusting shim, the second valve piece, the valve body, the locking shim and the locking nut. According to the two-stage valve mechanism of the single-cylinder shock absorber, an auxiliary blow-off point and a main blow-off point are formed on the basis of the characteristic of damping force, damping force can be formed at the auxiliary blow-off point at extremely low speed, the sudden change, caused by speed changes, of the damping force at the main blow-off point does not occur, strenuous vibration, caused by the sudden change of the damping force, of a vehicle is avoided, and riding comfort is improved.
Description
Technical field
The utility model relates to a kind of valve mechanism, relates in particular to a kind of two-stage valve mechanism of single drum shock absorber.
Background technique
At present, two-stage valve mechanism used does not become and comprises pair and blow and unload a little and main blowing unloaded a little on damping force characteristic, pair is blown to unload and a little can be guaranteed to form damping force under utmost point low speed, be unlikely to again at the main sudden change of unloading a little due to the variation generation damping force of speed, the vehicle strenuous vibration that can avoid damping force to suddenly change and cause of blowing; But because existing two-stage valve mechanism becomes on damping force characteristic, do not comprise pair and blow and unload a little and main blowing unloaded a little, do not improve ride comfort.
Model utility content
The technical problems to be solved in the utility model is, for the deficiencies in the prior art, and provides a kind of two-stage valve mechanism of single drum shock absorber.
The utility model solves the technological scheme that its technical problem adopts: the two-stage valve mechanism that a kind of single drum shock absorber is provided, comprise connecting rod, banking stop, the first valve block, spring sheet, two-stage valve sheet, piston, adjustment pad, the second valve block, valve body, lock washer and locking nut, described banking stop, described the first valve block, described spring sheet, described two-stage valve sheet, described piston, described adjustment pad, described the second valve block, described valve body, described lock washer and described locking nut are set on described connecting rod successively.
The utility model further preferred version is: between described banking stop and described the first valve block, be provided with the first pad.
The utility model further preferred version is: between described the second valve block and described valve body, be provided with the second pad.
The utility model further preferred version is: on the outer wall of described piston, be set with piston ring.
The utility model further preferred version is: described locking nut is threaded with described connecting rod.
Implement the technical solution of the utility model, there is following beneficial effect: the utility model includes pair and blows and unload a little and main blowing unloaded a little by having formed on damping force characteristic, pair is blown to unload and a little can be guaranteed to form damping force under utmost point low speed, be unlikely to again to blow the sudden change of unloading a little due to the variation generation damping force of speed main, the vehicle strenuous vibration of having avoided damping force sudden change to cause, has improved ride comfort.
