Rubber air spring is widely used in commercial vehicles, passenger cars, railway vehicles, mechanical equipment, construction base of self-adjusting air suspension.Rubber air spring consists of air and rubber.Its internal consumption is small, the isolation capacity is not affected by the natural vibration of the spring itself.In addition, the rubber spring has no metal contact, so the sound insulation effect is very good.
Spring stiffness: when designing the stiffness of the rubber spring, it can be selected by changing the internal pressure of the spring, and the stiffness is approximately proportional to the internal pressure.Therefore, for a given size of rubber spring, according to the need to choose a lower stiffness of the spring.The stiffness is variable and changes with the change of load. Therefore, under the action of any load, the natural frequency of vibration is almost constant, so that the supporting system has almost constant performance.
Rubber spring is connected to the additional air chamber, but rubber air spring natural vibration frequency of the plant decreased to 0.5 ∽ 3 hz.The rubber spring can maintain a low and nearly equal vibration frequency under any load.In the rubber spring and additional air, a hole is added between the chamber.When spring loads vibrate, air flows through the orifice causing a loss of energy, damping the vibration.
Rubber air springs are relatively inexpensive, easy to install and replace, easy to maintain and maintain, without frequent maintenance and refueling.
