Generally, the damping and formation of the shock absorber of the airbag can be adjusted by inflating or deflating. The airbag shock absorption of the cab is not comfortable enough, and it can be slightly deflated, so that the shock absorption damping will be weakened, forming a longer, and the vibration filtering effect is good.

Airbag shock absorption working principle:

1. Ease the hydraulic chamber volume change caused by the movement of the inner rod.
< br >
The liquid cannot be compressed, and the small amount of the inner cavity volume after the inner rod is pressed into it is enough to produce high pressure and shock absorber oil leakage. The shock absorption of general civilian vehicles is not filled by the hydraulic chamber, and some gas is retained to adapt to this volume change, but when the shock absorption is intense, the gas may make the hydraulic oil produce bubbles, and the bubbles will produce vibration and instability when they pass through the piston! The use of air bags can not only mitigate this volume change by shrinking, but also separate the oil and gas to avoid bubbles that affect the shock absorption effect.

2, anti-aircraft range effect, so that the hydraulic damping can work better! If there is no airbag, when the shock absorber is rapidly compressed, the space under the piston is likely to produce a vacuum, when the shock absorber bounces back, the vacuum is not damped within the stroke, affecting the effect of shock absorption, this area is called \"empty\
