Abstract
The invention discloses an inflatable vibration damper, which is characterized by including a sealed air chamber, a floating piston, an O-shaped seal ring, a compression valve, a working cylinder, a piston rod, a working piston and a rebound valve, wherein the floating piston is mounted at the lower part of the working cylinder and connected with one end of the working cylinder into the sealed air chamber; the piston rod is vertical to the floating piston; the O-shaped seal ring is mounted on the floating piston; the working piston is arranged above the O-shaped seal ring; and the compression valve and the rebound valve are mounted on the working piston. The structure of the inflatable vibration damper is simplified by adopting the floating piston, and meanwhile the O-shaped seal ring with a big cross section on the floating piston separates the high-pressure gas from the oil gas, thereby avoiding the oil emulsification.
Description
Technical field
The present invention relates to a kind of vibration damper, especially a kind of gas-filled type vibration damper.
Background technique
For quickening vehicle frame and the genuine decay of vehicle body, be the situation smoothness to improve automobile, in the suspension system inside of most of automobiles vibration damper is housed.Extensively adopt the two-way function telescopic shock absorber at present on the automobile, but beidirectional telescopic shock absorber complex structure, and be prone to oily emulsion.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of gas-filled type vibration damper in order to solve the deficiency of existing technology.
Technological scheme: in order to realize above purpose; A kind of gas-filled type vibration damper of the present invention; It is characterized in that: comprise sealed gas chamber, floating piston, O-ring seals, compression valve, work cylinder barrel, piston rod, working piston, rebound valve, floating piston is equipped with in the bottom of described working barrel, and floating piston and working barrel one end form sealed gas chamber; Described piston rod is perpendicular to floating piston; On the described floating piston O-ring seals is housed, described working piston is above O-ring seals, and described compression valve and rebound valve are contained on the working piston.
The O-ring seals of big section is housed on the described floating piston.
To impact the dither that produces in order reducing, to be filled with the nitrogen of high pressure in the sealed gas chamber because of receiving.
Beneficial effect: gas-filled type vibration damper provided by the invention has simple in structure, and the advantage that damping performance is good, and the big section O-ring seals that on floating piston, is equipped with can separate pressurized gas and oil gas, eliminate have emulsion.

Fig. 1 is a structural representation of the present invention.
Wherein 1, sealed gas chamber, 2, floating piston, 3, the O RunddichtringO, 4, compression valve, 5, the work cylinder barrel, 6, piston rod, 7, working piston, 8, rebound valve.
Embodiment
Further illustrate the present invention below in conjunction with accompanying drawing.
As shown in Figure 1ly the invention discloses a kind of gas-filled type vibration damper; Comprise sealed gas chamber 1, floating piston 2, O-ring seals 3, compression valve 4, work cylinder barrel 5, piston rod 6, working piston 7, rebound valve 8; Floating piston is equipped with in the bottom of described working barrel; Floating piston and working barrel one end form sealed gas chamber 1, and described piston rod 6 is equipped with O-ring seals 3 perpendicular to floating piston on the described floating piston; Described working piston 7 is above O-ring seals 3, and described compression valve 4 is contained on the working piston 7 with rebound valve 8.
When the wheel bob; The working piston of vibration damper is reciprocating in fluid, makes that to produce oil pressure between epicoele and the cavity of resorption of working piston poor, and pressure oil is just pushed compression valve 4 or rebound valve 8 open and flowed back and forth; Because valve produces bigger damping force to pressure oil, makes vibration attenuation.Owing to adopting floating piston 2 to reduce by a cover valve system, make designs simplification.Owing to be filled with high pressure nitrogen in the sealed gas chamber 1, can effectively reduce the dither that produces when wheel receives unexpected the impact, and help to eliminate noise.Because the O-ring seals 3 of big section is housed on the floating piston 2, separate pressurized gas and oil gas fully, eliminated oily emulsion.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
