Air Spring Advantages

1) For an air spring of the same size, when the internal pressure changes, different bearing capacities can be obtained. This makes the same air spring adapt to the requirements of various loads, so it is economical. While bearing vertical load, the air spring can also bear certain lateral load and transmit torque.

2) Increasing the total volume of the air spring can reduce the natural frequency of the vibration isolation system, which is a unique advantage of the air spring. The volume of the air spring body, due to the limited structural space, cannot be too large. In order to reduce the natural frequency of the vibration isolation system, an auxiliary air chamber can be installed, and the auxiliary air chamber can be arranged far away from the air spring. The volume of the auxiliary air chamber is increased, that is, the total volume of the air spring is increased, and the natural frequency of the air spring vibration isolation system is reduced.

3) The air spring can use the height control valve system to keep the working height of the air spring basically unchanged under different loads. Similarly, the height control valve can also be used to make the air spring have different heights under a certain load, so it can adapt to various structural requirements.

4) The air spring can absorb high-frequency vibration and has excellent sound insulation performance.
The air spring is mainly composed of rubber bladder and air. During the vibration process, the rubber bladder has very little internal friction due to stretching and warping, so it is difficult to transmit high-frequency vibration. Air and rubber do not transmit sound easily, so they have good sound insulation properties. The steel spring is easy to transmit high-frequency vibration and sound.

5) If an orifice is set between the main air chamber and the auxiliary air chamber of the air spring, when the air spring vibrates and deforms, there will be a pressure difference between the main and auxiliary air chambers, and the air flowing through the orifice will absorb part of the energy due to resistance , thus having a damping effect. Appropriate throttle aperture can improve the damping characteristics of the vibration isolation system and effectively suppress the resonance amplitude.
