Description
Technical field
The utility model relates to a kind of vehicular shock absorber that improves stability in the Vehicle Driving Cycle process, is specifically related to a kind of air-bag vibration damper.
Background technique
At present, the vibration damper of automobile use all belongs to hydraulic damper basically.Vehicle is jolting while travelling, and the piston rod of hydraulic damper is constantly made fore and aft motion in cylinder body, and the damping oil in cylinder body constantly, by current downflow on the valve block in valve body, carrys out shock absorbing power, extenuates degree of jolting.Due to, piston rod can make the cylinder body volume reduce while stretching in cylinder body, so can not fill with damping oil fully in cylinder body.Because of the damping oil in cylinder body, originally just can not fill with again, vibration damper also occurs inevitably that in use the factor such as leakage of oil causes oily loss, and the damping oil in cylinder body can be fewer and feweri.Like this, when vehicle jolts frequent and top width when larger, hysteresis is filled up in the circulation of cylinder body internal damping oil, vacuum very easily occurs below piston, and the idle running phenomenon appears in piston in cylinder body.In addition, in cylinder body, the air-fuel mixture result makes damping oil emulsification, and volume increases, and the piston original lower position of can not working again, make compression damping be increased to the numerical value that can not allow.And the emulsification damping oil easily can produce the abnormal sound that noise and vibration are sent during by valve block.Especially damping oil especially has some setbacks by valve block under low temperature condition, has a strong impact on damping effect.In recent years, occurred that the cylinder body lower curtate was filled with the new technology of pressurized gas.Chinese patent, the patent No. is 200620141855.7, the patented technology of " with the barrel type hydraulic shock absorber of floating piston " by name, bottom at cylindrical shell is equipped with float piston device, substantially the problems referred to above have been solved, but this technology is existent defect still, as it is too small to be filled with the volume of pressurized gas, and the vibration damper that can not adapt to big connecting rod uses.200620141855.7 of Chinese patents are called " with the barrel type hydraulic shock absorber of floating piston ", in the bottom of cylindrical shell, float piston device are installed.Float piston device comprises, the pressurized gas in columniform air reservoir, air reservoir, the floating piston above pressurized gas, embed on O-ring seals in floating piston external diameter groove, floating piston with air reservoir on along the back-up ring that fastens.This technology has not only overcome the mobile defect of filling up hysteresis of damping oil, has avoided the vacuum phenomenon in the vibration damper cylindrical shell, has eliminated piston idle running hidden danger in vibration damper; And the float piston device integrity is strong, no matter is arranged in the bitubular or single drum shock absorber, has equally installation and maintenance conveniently, and pressurized gas can be reused, and have improved the advantages such as vibration damper damping performance.But, should " with the barrel type hydraulic shock absorber of floating piston " still have defect.That is exactly, and due to the restriction in vibration damper space, is arranged on the float piston device small volume of cylinder body bottom, and when it slided up and down in clutch release slave cylinder at piston rod, to the space in cylinder body, the mobile regulating action of change and damping oil had certain limit.Namely its regulated quantity is less, is only suitable for being arranged on the vibration damper of dilly sending out its effect of brightness, can not adapt to the needs of large vibration damper.
The model utility content
The purpose of this utility model is to provide a kind of air-bag vibration damper of new structure, and not only damping performance is better for it, and simple in structure, can be suitable for more planting especially large vehicle use of working environment.
for realizing this damping purpose, the technical solution of the utility model is: a kind of air-bag vibration damper, comprise absorber main body, piston rod, oil deflector, piston assembly and fuel tank, in described absorber main body clutch release slave cylinder, be provided with fuel tank, described piston rod is inserted in fuel tank, described piston assembly is arranged on the piston rod tail end, described fuel tank upper end is provided with oil deflector, between described fuel tank and absorber main body clutch release slave cylinder, be provided with spongy layer, described link press span is connected spongy layer with the fuel tank inwall, the bottom of described fuel tank arranges a cylindrical shape air bag, in air bag, fill inert gas, described cylindrical shape air bag is provided with the high-pressure gasbag controlling device.
As improvement of the present utility model, described upper cover of piston rod is equipped with end cap, and the axial two ends of described air bag are connected with end cap with air bag seat respectively, and an end of described air bag seat and fuel tank socket-connects.
As improvement of the present utility model, on described piston rod, also be set with buffer stopper, described buffer stopper is between oil storage cylinder and end cap.
As improvement of the present utility model, described piston rod passes on the outer end of oil storage cylinder and is connected with suspension ring.
With respect to prior art, in damping oil between the utility model fuel tank and clutch release slave cylinder, be provided with spongy layer, spongy layer can absorb the foam that produces after damping oil emulsification at any time, make damping oil keep clear state, thereby damping oil is flowed in vibration damper very smooth and easy.Between whole fuel tank and clutch release slave cylinder, be installed on air bag and controlling device thereof, overcome damping oil and flowed and to fill up the hysteresis defect, avoided the vacuum phenomenon in the vibration damper cylindrical shell, eliminated piston idle running hidden danger in vibration damper, improve the performance of vibration damper, extended the working life of vibration damper.
