How to adjust the shock absorption of airbag in truck cab

Generally, the Pacific automobile network can adjust the damping and shaping of airbag shock absorption by inflating or deflating. The airbag in the cab is not comfortable enough for shock absorption, so it can be deflated slightly, so that the shock absorption and damping will be weakened, the formation will be longer and the shock absorption and filtering effect will be good.

Working principle of airbag shock absorption;

1. Relieve the volume change of the hydraulic cavity when the inner rod moves.

Liquid is incompressible. After the inner rod is pressed in, the volume of the inner cavity is slightly reduced enough to generate high pressure, that is, to absorb oil leakage. Generally speaking, the hydraulic cavity of civil vehicles is not full, and some gas will be reserved to adapt to this volume change. However, in the case of severe shock absorption, gas may produce bubbles in hydraulic oil, which will cause vibration and instability when passing through the piston! If the air bag is used, this volume change can be alleviated by contraction, and the oil and gas can be separated, so as to avoid the bubbles generated by the damping oil from affecting the damping effect.

2, air defense function, so that hydraulic shock absorption can play a better role! If there is no airbag, the space below the piston is likely to produce vacuum when the shock absorption is compressed rapidly, and there is no damping in the stroke of vacuum when the shock absorption rebounds, which affects the shock absorption effect. This area is called. Air travel? This situation doesn't matter much in civilian cars, but it is a big problem in racing cars that need high-speed and strenuous exercise for shock absorption! The shock absorption of air bag is equivalent to greatly increasing the air pressure of the hydraulic chamber by filling high-pressure gas, which can effectively avoid the vacuum generated at the lower end of the piston during shock absorption and compression? Air travel? And the shock absorption effect is also improved. (Photo/Text/Photo: Pacific Auto Network Cao Bo)
