Description
Technical field
The present invention relates to a kind of air-bag vibration dampers.
Background technique
The structure of air-bag vibration damper generally comprises oil cylinder, storage cylinder, piston is equipped in oil cylinder, an oil pipe is by oil cylinder and stores
Oil liquid when piston is pressurized, is discharged to storage cylinder, by oil liquid inspiration oil cylinder after piston reset, adjusts the valve on oil pipe by cylinder connection,
Adjustable resistance to compression pression；Its shortcoming is, when piston reset can bring the gas of storage cylinder into oil cylinder, the meeting when piston is pressurized
There is idle stroke, reduces damping effect；The adjusting of additional valves is indicated without gear.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of resistance to compression pression band adjustable monotubular air-bag vibration damper of gear,
The monotubular air-bag vibration damper can prevent gas from entering oil cylinder, in addition adjust the instruction of resistance to compression pression Shi Nengyou gear.
The technical scheme is that a kind of resistance to compression pression band adjustable monotubular air-bag vibration damper of gear comprising oil cylinder,
Storage cylinder is equipped with piston in oil cylinder, and the top of piston is compression chamber, and the lower part of piston is recovery chamber, between oil cylinder and storage cylinder
Be connected with lifting lug gap bridge, be equipped with check valve in storage cylinder, check valve includes valve seat, spool, elastic piece, valve seat by storage cylinder every
At two parts, the top of storage cylinder is oil suction chamber, and the lower part of storage cylinder is oil storage chamber, and spool is inserted in valve seat, and valve seat is equipped with
Aperture, aperture is symmetrical around spool, and elastic piece can cover aperture, and elastic piece sealing shroud is equipped with connection on spool in spool
The oil duct of logical oil suction chamber and oil storage chamber, is connected with oil pipe between the oil suction chamber of storage cylinder and the compression chamber of oil cylinder, characterized in that In
The bottom surface of valve seat extends downwardly out a fuel sucking pipe.
The working principle of the invention is, in piston pressurized process, the oil liquid in the compression chamber of oil cylinder enter storage cylinder into
The oil liquid of oil pocket, oil suction chamber enters oil storage chamber by oil duct, the fuel sucking pipe of check valve；During piston reset, in oil storage chamber
Oil liquid compression chamber is returned to by fuel sucking pipe, aperture (elastic piece is opened by suction at this time), oil pipe, and the gas in oil storage chamber is not
Compression chamber can be entered.The beneficial effect is that the function for making damper that there is automatic exhaust and compensation oil liquid due to being provided with fuel sucking pipe
Can, to guarantee zero idle running of damper, improve damping effect.
