Rubber Air Spring W01-358-0118 Single Convoluted Type Air Bags For Trailer Rear Axle Suspension

Product Description

A rubber air spring is an industrial component that uses compressed air to provide elasticity. It is made of high-quality rubber and fabric layers vulcanized at high temperature, with compressed air enclosed within to form a flexible airbag. Its core feature is the use of air compressibility to achieve nonlinear stiffness, while adjusting the internal air pressure to precisely control load capacity and height.

The main advantages are its low natural frequency, excellent vibration isolation, and effective suppression of high-frequency noise. Compared to traditional steel springs, it offers lighter weight, better cushioning, and longer service life while maintaining the same load capacity. It is widely used in automotive suspension systems, industrial machinery vibration isolation, and precision instrument mountings, making it a key elastic component in modern vibration control engineering.

Application of Rubber Air Springs in Trailer Axles

On trailers, air springs are typically not used independently, but are integrated into a mechanical arm or four-link suspension. In this configuration, the rubber air spring primarily bears vertical loads and provides elasticity, while the links and arms are responsible for positioning the axle and transmitting driving and braking forces.

1. Automatic Balancing and Stable Load-Bearing:

Whether the trailer is unloaded or loaded, air springs maintain a relatively constant frame height by adjusting the air pressure within the airbags, ensuring the axle is always optimally loaded.

When the vehicle is traveling on rough roads or when the wheel loads are uneven, the system automatically adjusts to prevent tilt and improve driving stability.

2. Excellent Vibration Damping Performance:

Compared to traditional leaf springs, air springs have a lower stiffness and a natural vibration frequency typically between 1 and 1.5 Hz, effectively filtering and absorbing high-frequency, subtle vibrations and large shocks from the road.

This significantly protects cargo, especially high-value goods that are sensitive to vibration (such as precision instruments and fragile items), and reduces impact damage to the vehicle frame.

3. Protects Axles and Tires:

Smooth load distribution and excellent vibration damping significantly reduce "axle hopping" (where the axle jumps off the ground during bumps), thereby reducing fatigue damage to axles and suspension components.

Maintaining a level vehicle body helps ensure even tire contact, reducing abnormal wear and extending tire life.

4. Improves Driving Safety:

Provides better lateral support during cornering, reducing body roll and improving handling stability.

Cooperates more effectively with electronic systems such as ABS and ESC, as the wheels maintain more continuous contact with the ground.
