Description
Technical field
The utility model relates to automobile absorber field, is specifically related to a kind of damping pillar vibration damper that moves good.
Background technique
Make it more comfortable in order to improve the stationarity of automobile running; vibration damper can be installed in automotive suspension conventionally; its working principle is in the time being subject to vibrations to occur relative movement between vehicle frame and vehicle bridge; piston in vibration damper is up and down; fluid in vibration damper chamber just flows in another chamber from different spaces repeatedly in a chamber; now; the intermolecular interior friction of friction between hole wall and fluid and fluid forms damping force to vibrations; the heat energy that the Conversion of Energy that makes thump is fluid, then have vibration damper to absorb to be transformed in air and to go.
Current vibration damper generally includes clutch release slave cylinder, oil storage cylinder, connecting rod, piston valve, bottom valve, oil sealing guidance set, the vibration damper of this structure can reach certain damping effect, but, in the time that vibrations are excessive, the speed that connecting rod stretches out is faster, fluid in vibration damper flows faster thereupon, cause oil sealing guidance set to produce more large impact, oil sealing guidance set is easily damaged, thereby will affect vibration damper damping effect, and vibration damper is in the time of work, the stretching into and stretch out variation and the gas pressure change that can cause the shared volume of gas in the jar of connecting rod, in the time that gas pressure reduces, gas molecules a large amount of in cylinder inner fluid can be separated, the cavitation of fluid will be caused, thereby affect damping effect, and in the time that gas pressure increases, in cylinder, a large amount of gas molecules is dissolved into again in fluid, serious fluid foamed will be caused, thereby solid surface can produce cavitation erosion, damage threshold is part, cause product to decline working life.
Model utility content
The technical problems to be solved in the utility model has been to provide the damping pillar vibration damper that a kind of motility is good, solve existing vibration damper in the time that damping is excessive, the large fragile oil sealing guidance set of its cylinder inner fluid impact force, and connecting rod repeatedly moves down and easily causes cylinder inner fluid cavitation and fluid foamed phenomenon, thereby affect damping effect, can damage threshold be even part, cause the defect of product decline in working life.
Adopt following technological scheme in order to solve the existing technical problem the utility model of background technique: the damping pillar vibration damper that a kind of motility is good, comprise clutch release slave cylinder, oil storage cylinder and be arranged at the connecting rod in clutch release slave cylinder, described connecting rod bottom is provided with piston valve, described clutch release slave cylinder bottom is provided with bottom valve, between described clutch release slave cylinder and oil storage cylinder top, be provided with oil sealing guidance set, between described clutch release slave cylinder and oil storage cylinder, be provided with annular air-pocket, it between described annular air-pocket and clutch release slave cylinder and oil storage cylinder, is Spielpassung, in described clutch release slave cylinder, be provided with recovery Buffer Unit, this recovery Buffer Unit comprises return spring and packing holder, described return spring is set in connecting rod one end near oil sealing guidance set, described packing holder is set in connecting rod and connects away from one end of oil sealing guidance set with return spring.By this setting, the gas pressure producing in described annular air-pocket can stretch out the pressure decreased causing by compensation link, thereby can avoid cavitation phenomenon, and because annular air-pocket has occupied space in cylinder substantially, make gas in the jar molecular amounts few, fluid is absorbed less than a large amount of gas molecules, thereby can avoid the consequence of fluid foamed, can be good at relaxing the impact of fluid to oil sealing guidance set and restore damping device, its impact force is diminished greatly, thereby make vibration damper can keep good damping effect.
Further setting of the present utility model: also include dust preventing component, described dust preventing component comprises the dust-proof cover that is installed on outside, oil storage cylinder top and the dust cover that is fixed on dust-proof cover upper end.By this setting, it is interior to avoid fluid to become muddy that dust-proof cover can be good at stoping dirt to enter cylinder body, and dust cover can further increase overall dust-proof effect, thereby make vibration damper can keep good damping effect.
Further setting of the present utility model: also include spring tray, described spring tray is set in the outside of oil storage cylinder by the mode of welding.By this setting, can increase the tensile strength of whole vibration damper, and spring tray can avoid it in the time that vibration damper is worked, to be shifted and even to come off by being welded and fixed on fuel tank, make vibration damper damping more stable.
Further setting of the present utility model: also include knuckle bracket assembly, described knuckle bracket assembly is installed on oil storage cylinder exterior bottom.By this setting, be conducive to vibration damper and be better installed on automobile suspension system, and when work in, is more stable.
Further setting of the present utility model: be provided with annular groove on the outer ring surface of described packing holder, described annular groove inner sleeve arranges O RunddichtringO.By this setting, the better position of fixing seal ring support, the while has further increased the sealing of packing holder.
The beneficial effects of the utility model are: the utility model by being provided with recovery Buffer Unit in clutch release slave cylinder, can well relax the impact of fluid to oil sealing guidance set, and by be provided with annular air-pocket in oil storage chamber, can well avoid the phenomenon of fluid cavitation and fluid foamed, thereby can keep good damping effect, make its longer service life.
