Description
Technical field
The utility model relates to a kind of damper components structure, and especially one makes to restore during high speed valve leaf to produce damping value decay less, it is to increase the absorber valve arrangement of the stability of vibroshock.
Background technology
In the design and use procedure of shock absorber for vehicle, the function of piston valve sub-assembly is: vehicle produces recovery damping force in motion, suppresses the vibration of vehicle body, makes vehicle have good comfortable property and stable operation performance. Piston valve sub-assembly comprises flowing valve and restores valve, restore valve and produce recovery damping force when absorber stroke, therefore need vibroshock have under fixing speed certain recovery damping force value and through after a while use after, the decay of its recovery damping force value is less, could ensure that heavy vehicle vibroshock uses under severe conditions and extends its work-ing life. At present in the absorber designing of heavy vehicle, it restores the main architecture of valve has pure valve structure and valve block to restore valve spring unitized construction.
Along with the development of current heavy vehicle, the working conditions of heavy vehicle is increasingly severe, it is desired to the force value under fixing speed is increasing. With the increase of the force value of vibroshock under fixing speed, and exceed the also corresponding increase of the force value under fixing speed. The increase of product force value, the corresponding increase of vibroshock internal temperature, after temperature raises, vibroshock fluid is boiling just, producing a large amount of steam bubbles, it is shattered to pieces that a large amount of steam bubbles assembles generation under certain condition, causes internal hydraulic pressure to impact and high temperature, its steam inside voltage rise height, to temperature and the pressure increase of oil sealing sub-assembly lip. When internal pressure raise surpass and exceed oil sealing sub-assembly bear pressure time, it is easy to causing oil sealing sub-assembly transient failure, high-voltage oil liquid breaks through that oil sealing sub-assembly enclasping force is spouting causes oil leakage phenomenon.
According to above analysis, solve and force value under controlling to exceed fixing speed is extremely urgent. Now conventional above-mentioned its flowing valve structure of two kinds of valve architecture identical (by piston baffle, flowing valve valve block, flowing valve pad composition), difference is that valve leaf, piston pad, piston backing plate and piston nut form the recovery valve of pure valve structure by restoring, and the recovery valve that valve block restores valve spring unitized construction forms by restoring valve leaf, restore valve liner, restore valve spring and restore valve nut.Both control at a high speed, and some force value principles are consistent, are all that restore valve leaf distortion when high speed after, fluid forms the throttling of oil stream circulation passage by the narrow slot restored between valve leaf and piston valve line. Owing to by piston backing plate or the impact restoring valve liner, the fluid fixed flow circulation passage that point is formed at a high speed is limited. Along with vibroshock move to more speed time, oil stream circulation passage area cannot increase, and promotes that damping force value at higher speeds increases suddenly, and force value rising slope is relatively big, easily causes leakage of oil risk.
Practical novel content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is: provide one to make to restore valve leaf generation damping value decay during high speed less, it is to increase the absorber valve arrangement of the stability of vibroshock.
In order to achieve the above object, the utility model is achieved through the following technical solutions: absorber valve arrangement, comprise connecting rod, connecting rod is from left to right set with piston baffle, flowing valve pad, flowing valve valve block, piston, Chang Tongkong valve block successively, restores Valve seal, restore valve leaf, restore valve gasket, piston backing plate and piston nut; Described piston is offered and runs through piston and two ends terminate in flowing valve valve block and the oil through of normal through hole valve block respectively; Described recovery valve leaf becomes arch, and the top of arch contacts with recovery valve gasket.
The anchor ring of described piston is embedded with the sustained ring strengthening sealing property.
Described recovery valve leaf adopts SK5 alloy steel material to be made SK5.
The beneficial effects of the utility model are: absorber valve arrangement of the present utility model, by the cooperation of piston baffle, flowing valve pad, flowing valve valve block, piston, Chang Tongkong valve block, recovery Valve seal, recovery valve leaf, recovery valve gasket, piston backing plate and piston nut etc., make during high speed, to restore valve leaf generation damping value decay less, it is to increase the stability of vibroshock. The sustained ring strengthening sealing property owing to being embedded with on the anchor ring of described piston, enhances the intensity of piston, extends work-ing life. Owing to described recovery valve leaf adopts SK5 alloy steel material to be made, there is good elasticity, restore the decay of valve leaf damping value when ensure that high speed little, it is to increase the stability of vehicle and comfortable property, extend work-ing life.
