Application of rubber air spring
1. Application of rubber air spring in vehicle suspension system
The suspension system with rubber air spring as the elastic component is called air suspension system. The air suspension system is installed on the top grade bus, car and tractor in foreign countries. The air suspension system is being trial-produced or prepared to be used on the middle and top grade bus in China. After the vehicle with air suspension system, can realize automatic adjustment of body height, body height remains the same, rubber air spring low natural frequency, damping and sound insulation effect is good, can greatly improve the traffic smooth line, take the softness and comfort, at the same time, which can effectively protect the car itself and transportation of precision instrument and electrical equipment, Reduce maintenance times and reduce maintenance costs, prolong the service life of the vehicle, and greatly reduce the impact of the vehicle on the road surface, prolong the service life of the road surface. With the maturity of the application technology of air suspension system in China and the implementation of the new regulations on the evaluation of bus quality, the application prospect of air spring in vehicles will be more and more widespread and broad.
2. Application of rubber air spring in lifting equipment
Traditional lifting equipment adopts cylinder or hydraulic cylinder to lift objects, which requires large installation space, difficult manufacturing, heavy weight, prone to leakage and inconvenient maintenance. After using rubber air spring as lifting element of lifting equipment, it overcomes the traditional shortcomings of lifting equipment, no need for maintenance, long service life, easy operation and replacement. Therefore, rubber air springs are gradually replacing cylinder products in lifting equipment.
3. Rubber air spring is used in damping equipment
The advantages of high frequency vibration isolation, sound insulation and low natural frequency of rubber air spring can better realize vibration isolation and ensure the safety and stability of the base and control system of vibration equipment. Therefore, rubber air spring is widely used in such equipment as vibration isolation of vibrating screen, vibration reduction of luxury vehicle seats.
4. Rubber air spring other uses
Using rubber air spring as damping base can effectively protect precision equipment from damage during transportation, such as missile and control launcher transportation. Rubber air spring as a support tool, the use of its light weight, easy to operate characteristics, easy to field vehicles and equipment maintenance and so on
