The gas spring can keep the natural vibration frequency unchanged under any load, can bear radial and axial loads at the same time, and can also transmit a certain torque. Different bearing capacities can be obtained by adjusting the internal pressure.

Working principle of gas spring:

Gas spring is made when the sealed pressure cylinder is filled with noble gas or oil-gas mixture, so that the pressure in the cavity is multiple times higher than the atmospheric pressure, and the pressure difference generated by the cross-sectional area of the piston rod being smaller than that of the piston used to achieve movement of the piston rod. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (noble gas or oil-air mixture), in-cylinder control elements and out-of-cylinder control elements (referring to controllable gas springs) and joints. Due to the fundamental difference in principle, gas springs have significant advantages over ordinary springs: relatively slow speed, little change in dynamic force (generally within 1:1.2), and handy control; the disadvantage is that it is bigger than the coil spring.

According to its characteristics and application fields, gas springs are also called support rods, angle adjusters, gas pressure rods, dampers, etc. Nowadays, the product is widely used in automobile, aviation, medical equipment, furniture, machinery manufacturing and other fields. Its deformation and load-load relationship characteristic line is a nearly linear curve, which means it can be designed according to needs. The elastic coefficient X of the standard gas spring is between 1.2 and 1.4, and other parameters can be flexibly adjusted according to requirements and working conditions.

There are many structural forms of air springs, such as bladder type and membrane type, which are often used in vehicle suspension and anti-vibration systems of mechanical equipment. Gas spring is an industrial accessory that can function as support, buffer, braking, height adjustment and angle adjustment.
