Rubber air springs are commonly known as pneumatic tires, corrugated pneumatic tires, and airbags. It is a precision-designed rubber fiber bellows. It does not provide force or support load by itself. Instead, it is filled with compressed air through an air compressor to achieve force transmission and elasticity. According to the requirements of the stroke, the air spring is generally designed to be 1-3 bends, and can also be designed and manufactured to be 4 bends or more than 5 bends when necessary. Under certain conditions, two air springs can also be used in stacks.

The air spring has non-linear characteristics, and its stiffness changes with load, so its natural frequency remains almost unchanged under any load, so that the spring device has almost unchanged characteristics; it has good performance in absorbing high-frequency vibration and sound insulation; It bears axial load and radial load at the same time, and through adjustment of internal pressure, different load-bearing capacities can also be obtained. Therefore, it can adapt to a variety of load needs.

In the effective stroke of the air spring, the stiffness, height, internal volume of the cavity and the bearing capacity of the air spring are adjusted by increasing or decreasing the inflation pressure. At the same time, its stiffness, height, cavity volume, and bearing capacity will undergo steady and periodic flexible changes as the load increases, so as to realize the flexible transmission of the bearing capacity, the effective adjustment of the stroke, and the vibration amplitude and load. Efficient control. An air chamber can also be added to realize automatic adjustment.

Due to the above characteristics, air springs are increasingly widely used in trains, automobiles, paper machines, lifting platforms, presses, vibrating conveyors, vibrating screens, air hammers, vibration testing machines, casting machinery, etc., which require stroke control or reduction Earthquake, seismic isolation equipment or instruments.
