How does the rubber air spring achieve vibration reduction?
With the maturity of the application technology of the domestic air spring suspension system and the implementation of the new regulations on the quality level evaluation of passenger cars, the application prospect of rubber air springs on vehicles will become more and more common and broad.
When the vehicle adopts the air suspension system, the height of the vehicle body can be automatically adjusted, the height of the vehicle body is kept constant, the natural frequency of the rubber air spring is low, the vibration damping and the sound insulation effect are good, and the smooth running of the vehicle can be greatly improved, and the seat can be greatly improved. Softness and comfort, while protecting the car's own and transporting precision instruments and electrical equipment, reducing the number of repairs and reducing maintenance costs, extending the life of the vehicle, and greatly reducing the impact of the vehicle on the road surface, extending the use of the road surface life.
When the rubber air spring is working, the inner chamber is filled with compressed air to form a compressed air column. As the amount of vibration load increases, the height of the spring decreases, the volume of the inner cavity decreases, the stiffness of the spring increases, and the effective bearing area of the inner air column increases, and the load carrying capacity of the spring increases. When the vibration load decreases, the height of the spring increases, the volume of the inner cavity increases, the stiffness of the spring decreases, and the effective bearing area of the inner air column decreases, and the load carrying capacity of the spring decreases. Thus, in the effective stroke of the air spring, the height of the air spring, the volume of the inner cavity, and the load carrying capacity are smoothly controlled by the flexible transmission, the amplitude and the vibration load with the increase and decrease of the vibration load. It is also possible to adjust the stiffness and bearing capacity of the spring by increasing or decreasing the amount of inflation, and an auxiliary air chamber can be attached to achieve self-control adjustment.
