The present invention provides an improved structure of automobile shock absorber, which belongs to Shock Absorber technology. It solved the existing technologies that are more complex structure, the noise, vibration effect is not satisfactory, shorter service life deficiencies.Shock absorber, including one outside cylinder, a cylinde sets outer tube, the cylinder barrel and the piston is connected to the piston rod and the cylinder piston will be separated into upper and lower chamber cavity, the outer end rod extending out cylinder, described at the bottom of a cylinder and cylinder connected to the inferior vena cava through the tubing, Qualcomm, which covers the extension of the pipeline through the cylinder to the cavity, Cylinder the inferior vena cava and the superior vena cava link. Improve the structure of the automobile shock absorber design of the structure is not only reasonable regulation of stability, and work noise, the advantages of long life, and can be easily carriedout to improve the existing technical.
