Abstract

The utility model discloses a kind of air-bag vibration damper, including body, body is provided with fuel tank, piston-rod assembly and air bag are provided with inside fuel tank, piston-rod assembly is provided with the compression valve and rebound valve for moving with it velocity magnitude and changing channel cross-sectional area, and compression valve is located at piston-rod assembly top, rebound valve is located at piston-rod assembly bottom, shock absorber fluid is filled in fuel tank, air bag is in piston-rod assembly lower section, nitrogen is full of in air bag.When piston-rod assembly pumps, larger damping force is produced to shock absorber fluid, make shock attenuation.The utility model has buffering strength abundance, and sealing structure is good, the preferable advantage of damping effect.

Description

A kind of air-bag vibration damper
Technical field
The utility model is related to damper, more particularly to a kind of air-bag vibration damper.
Background technology
Air-bag vibration damper mainly includes oil drum, and piston rod is equipped with oil drum, is connected with the outside of oil drum close The air bag of envelope, but existing damper air bag is generally only at one of oil drum, active force is smaller and easily cause buffering strength Sealing property between deficiency, and air bag and oil drum is also poor, and damping effect is also not ideal enough.
Utility model content
To overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of air-bag vibration damper.
The utility model is by the technical scheme that solution its problem is used:
A kind of air-bag vibration damper, including body, the body are provided with fuel tank, and it is total to be provided with piston rod inside the fuel tank Into and air bag, the piston-rod assembly is provided with compression valve and the extension for moving with it velocity magnitude and changing channel cross-sectional area Valve, the compression valve is located at piston-rod assembly top, and the rebound valve is located at piston-rod assembly bottom, is filled in the fuel tank Shock absorber fluid, the air bag is in piston-rod assembly lower section, and nitrogen is full of in the air bag.
Further, the compression valve and rebound valve are made up of spring steel plate, the spring steel plate thickness is identical, diameter not Deng.
Further, the body is provided with annular hanger.
Further, air bag activity in fuel tank is set, and the air bag is strip.
Further, the body is additionally provided with inflator pump, and the inflator pump end face is provided with charge valve.
Further, the fuel tank bottom is provided with the spongy layer for absorbing produced foam after shock absorber fluid is emulsified.
The beneficial effects of the utility model are:A kind of air-bag vibration damper that the utility model is used, by total in piston rod Nitrogen air bag is set into setting, when piston-rod assembly pumps, to damper in compression valve, rebound valve, fuel tank Oil produces larger damping force, makes shock attenuation.The utility model has buffering strength abundance, and sealing structure is good, damping effect The preferable advantage of fruit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Label in figure:1- bodies;2- fuel tanks;3- piston-rod assemblies;4- air bags;5- compression valves;6- rebound valves;7- annulars Hanger;8- inflator pumps;9- charge valves;10- shock absorber fluids;11- spongy layers.
Specific embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model provides a kind of air-bag vibration damper, including body 1, body 1 is provided with fuel tank 2, stores Piston-rod assembly 3 and air bag 4 are provided with inside oily cylinder 2, piston-rod assembly 3 is provided with and moves with it velocity magnitude and change passage and cut The compression valve 5 and rebound valve 6 of area, compression valve 5 are located at the top of piston-rod assembly 3, and rebound valve 6 is located at the bottom of piston-rod assembly 3, Shock absorber fluid 10 is filled in fuel tank 2, air bag 4 is in the lower section of piston-rod assembly 3, nitrogen is full of in air bag 4.
In the present embodiment, compression valve 5 and rebound valve 6 are made up of spring steel plate, and spring steel plate thickness is identical, diameter. Body 1 is provided with annular hanger 7.The activity in fuel tank 2 of air bag 4 is set, and air bag 4 is strip.Body 1 is additionally provided with inflator pump 8, The end face of inflator pump 8 is provided with charge valve 9.The bottom of fuel tank 2 is provided with for absorbing produced foam after shock absorber fluid 10 is emulsified Spongy layer 11.
During specific implementation, change the compression valve 5 of channel cross-sectional area on piston-rod assembly 3 equipped with velocity magnitude is moved with it With rebound valve 6.When wheel bob, the piston-rod assembly 3 of damper moves reciprocatingly in shock absorber fluid 10, makes piston Generation oil pressure is poor between the epicoele and cavity of resorption of the separation fuel tank 2 of bar assembly 3, and shock absorber fluid 10 just pushes compression valve 5 and rebound valve 6 open And flow back and forth.Because compression valve 5 and rebound valve 6 produce larger damping force to shock absorber fluid 10, make shock attenuation.And, Shock absorber fluid 10 is all filled in the fuel tank 2 of damper, air bag 4 can compress when piston-rod assembly 3 is down moved, increase gas Pressure, when piston-rod assembly 3 is up stretched, air bag 4 can increase, and air pressure can reduce.What is be full of in air bag 4 is nitrogen, due to nitrogen Heat endurance is better than air, brings the effect of more stable damping.
The above, simply preferred embodiment of the present utility model, the utility model is not limited to above-mentioned implementation Mode, as long as it reaches technique effect of the present utility model with identical means, should all belong to protection domain of the present utility model.
