Air bellow cabin shock absorber is a kind of pneumatic shock absorber, is the use of pneumatic resistance to shock products. Now cars, trains, aerospace, subways, machine tools, trucks are widely used.

Ease the hydraulic chamber volume change when the inner rod moves! The liquid can not be compressed, after the inner rod is pressed into the cavity volume of a little smaller is enough to produce high pressure is shock absorption oil leakage! General civil car shock absorption is through the hydraulic chamber is not filled, retain part of the gas to adapt to the volume change, but shock absorption violent movement, gas may make the hydraulic oil bubble, bubble through the piston will produce vibration and instability! If the air bag is used, it can not only reduce the volume change by shrinking, but also separate the oil and gas, so as to avoid the impact of shock absorption oil bubbles!

Air defense range function, so that hydraulic damping can work better! Without airbags, damping fast compression, the piston is likely to produce the vacuum of space, shock rebound again, produces the vacuum inside the leg of a journey is without damping, influenced the effect of shock absorption, this area is known as the "idle", this kind of situation in the civil car didn't matter much, but used in shock absorbers 20427897 need to racing on the problem of high speed, strenuous exercise is big! And the air bag shock absorption through charging high pressure gas, equivalent to greatly improve the pressure of the hydraulic chamber, can effectively avoid shock absorption compression piston lower end of the vacuum "empty path", also improve the effect of shock absorption!
