The structure and characteristics of air spring
Air spring is a kind of elastic element which uses the reaction force of compressed air inside the rubber bag as elastic restoring force. Air spring is widely used in power machinery, electronic equipment, instrumentation, chemical machinery and other equipment in automobile, railway vehicle, ship, aviation, industry and other fields by virtue of its good vibration absorption and isolation performance.

1, air spring structure form
Air spring is a non-metallic spring that fills a flexible rubber bag with air under a certain pressure and uses the compressibility of air to achieve elastic effect. Air spring is mainly divided into two categories: capsule air spring and membrane air spring.
In the current mechanical design process, the air spring has long been like a gear, can be treated as a standard part, according to the weight of the load and geometric installation size can choose the corresponding air spring.

2, the characteristics of air suspension
(1) The elastic coefficient of air spring is variable. With the increase of the load, the elastic coefficient also increases. Air spring can be designed to meet all kinds of performance requirements of the effect curve, because the air spring has nonlinear effect.
(2) the air spring rubber body is relatively light, the quality of air is also very small, the weight of the air spring comes mostly from the upper cover and the lower cover, unlike the steel spring, the metal is heavier.
(3) The bearing capacity of the air spring can be adjusted according to the size of the inflation pressure in the rubber bag. For the same air spring, the size of the inflation pressure can be adjusted to meet the needs of different bearing capacity.
(4) Because the air spring takes the air as the elastic medium, when compressed, the internal friction is small, so the vibration isolation effect is better. In addition, the air spring has a good ability to eliminate noise, because the ability of air and rubber to transmit sound is relatively weak.
(5) the fatigue resistance of air spring is relatively strong, the experiment shows that: under normal circumstances, the stress cycle number of leaf spring can withstand is 500,000 to 600,000 times, and the general air spring can reach about 3 million times, and the stress cycle number of high-quality air spring can withstand can reach more than 5 million times. Therefore, the air spring has outstanding effect in resisting strain.
