The gas spring is in a sealed container charged with compressed gas by the gas compressibility achieve its spring action. Such stiffness of the spring is variable because of the additional spring acting on the load, quantitative gas pressure in the container increases, an increase in stiffness of the spring. Conversely, when the load is reduced, the air pressure in the spring drop, reduced stiffness, so it has a more desirable elastic characteristics.
1. The structural characteristics of the gas spring
and the air spring and gas spring with coil springs are the same, only carry axial load, the gas spring suspension must be set in vertical and horizontal thrust rod etc. guide mechanism, but also it must have a damper. The gas spring can automatically adjust the height of the original surface of the inflation pressure of the gas chamber through a special height control valve.
2. The gas spring type
Gas spring and is divided into two types of air springs and gas springs.
