The difference between gas spring and rubber air spring:

The gas spring is an elastic element with gas and liquid as the working medium. It is composed of a pressure tube, a piston, a piston rod and a number of coupling parts. Its interior is filled with high-pressure nitrogen. Because there are through holes in the piston, the gas at both ends of the piston The pressure is equal, and the cross-sectional area on both sides of the piston is different. The piston rod is connected to one end and the other is not at the end of the gas spring. Under the action of the gas pressure, the pressure to the side with the smaller cross-sectional area is generated, that is, the elastic force of the gas spring, the magnitude of the elastic force It can be set by setting different nitrogen pressures or different diameter piston rods. Unlike mechanical springs, gas springs have a nearly linear elastic curve. The elastic coefficient X of the standard gas spring is between 1.2 and 1.4, and other parameters can be flexibly defined according to requirements and working conditions.
When the rubber air spring is working, the inner cavity is filled with compressed air to form a compressed air column. As the amount of vibration load increases, the height of the spring decreases, the volume of the inner cavity decreases, the rigidity of the spring increases, the effective bearing area of the air column of the inner cavity increases, and the bearing capacity of the spring increases at this time. When the vibration load decreases, the height of the spring increases, the volume of the inner cavity increases, the rigidity of the spring decreases, the effective bearing area of the air column of the inner cavity decreases, and the bearing capacity of the spring decreases at this time. In this way, the air spring is in an effective stroke, and the height, cavity volume, and bearing capacity of the air spring are smoothly and flexibly transmitted, and the amplitude and the vibration load are efficiently controlled as the vibration load increases and decreases. It is also possible to adjust the stiffness and bearing capacity of the spring by increasing or decreasing the amount of inflation. An auxiliary air chamber can also be attached to achieve automatic control adjustment.
