Rubber air spring working principle

When the air spring is working, the inner cavity is filled with compressed air (working pressure<0.7MPa) to form a compressed air column. As the vibration load increases, the height of the spring decreases, the volume of the inner cavity decreases, the stiffness of the spring increases, the effective bearing area of the air column in the inner cavity increases, and the bearing capacity of the air spring increases at this time. When the vibration load decreases, the height of the spring increases, and the volume of the inner cavity increases. The stiffness of the spring decreases, and the effective bearing area of the air column in the inner cavity decreases, and the load-bearing capacity of the spring decreases at this time. In this way, the air spring is within the effective stroke. The height, inner cavity volume, and bearing capacity of the air spring are smoothly and flexibly transmitted with the increase and decrease of the vibration load. The working principle is shown in the figure. Plane A-A is tangent to the surface of the air spring capsule. and perpendicular to the capsule axis (a). The air spring uses the air inside the rubber airbag as an elastic medium. When the air is compressed, the air will generate a counter force, and this counter force will produce an elastic restoring force.
