Abstract
The utility model discloses an inflatable bumper shock absorber floating piston seal structure, it leans on both ends to install an annular guidance tape respectively in the piston rod cavity of an inflatable bumper shock absorber on the floating piston outer wall circumference between hydraulic pressure room and the air chjamber, be fixed with a gas -liquid sealing washer in the middle of floating piston's outer wall on the circumference, and the hole of installing a sealed opposite direction respectively between gas -liquid sealing washer and two guidance tapes is with this special sealing. The utility model discloses not only can improve the sensitivity and the stability of the motion of floating piston and piston rod, wear resistance is good moreover, prevents inside hydraulic oil and high -pressure gas seepage of each other, improves holistic life.
Description
Technical field:
This utility model is that the air filling type shock absorber floating piston installed on a kind of vehicle seals structure.
Background technology:
Along with increasing of vehicle, the aspect such as comfortableness for vehicle stability under steam, driver and crew is proposed higher requirement.Current air filling type shock absorber floating piston seals structure, and main employing o-ring seals structure, and what exist major downside is that, frictional resistance is big, and gas and the mutual seepage of liquid easily occur, the motion sensitivity reduction of piston.Not only damping performance is poor, and easily o-ring is worn and torn, and reduces the service life of whole amortisseur.
Summary of the invention:
The purpose of this utility model is to provide a kind of rational in infrastructure, and the motion sensitivity not only making piston is good, improve damping performance, and the air filling type shock absorber floating piston that can be greatly improved service life seals structure.
The technical solution of the utility model completes as follows, a kind of air filling type shock absorber floating piston seals structure, it is characterized in that: it is to be separately installed with an annular guidance tape by two ends on floating piston outer wall circumference between hydraulic pressure chamber and air-pressure chamber in the plunger of an air filling type shock absorber, the outer wall intermediate circumference of floating piston is fixed with a gas-liquid sealing circle, between gas-liquid sealing circle and two guidance tapes, is separately installed with one seals this special envelope of hole in opposite direction.
This utility model not only can improve susceptiveness and the stability of floating piston and piston rod movement, and anti-wear performance is good, it is prevented that internal hydraulic pressure oil and the mutual seepage of gases at high pressure, improves overall service life.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Embodiment is described in detail in conjunction with accompanying drawing, it is to be separately installed with an annular guidance tape 2 by two ends on floating piston 6 outer wall circumference between hydraulic pressure chamber 8 and air-pressure chamber 7 in piston rod 1 cavity of an air filling type shock absorber, the outer wall intermediate circumference of floating piston is fixed with a gas-liquid sealing circle 4, between gas-liquid sealing circle and two guidance tapes, is separately installed with one seals this special envelope 3 and 5 of hole in opposite direction.The purpose arranging sealing ring in the middle of floating piston outer wall is, for preventing hydraulic oil and the mutual seepage of gases at high pressure of the left and right sides.Occur scraping to destroy its sealing property when guidance tape is used for preventing floating piston to be subject to External Force Acting with piston rod inwall, guidance tape also has self-lubricating property, the frictional force between piston rod and floating piston can be reduced, so this utility model compared with prior art not only increases susceptiveness and the stability that floating piston moves in piston rod, and improve the sealing between amortisseur internal high pressure oil and gases at high pressure, thus improve the whole service life of amortisseur.
