Automotive air spring is a spring element that is filled with compressed air in a retractable airtight container and utilizes the elastic action of air to achieve its elastic function. It is often referred to as an airbag, airbag cylinder or skin cylinder, etc. Air springs adjust the height of the body and the stiffness of the suspension system by controlling the internal air pressure, thus adapting to different road conditions and driving states, and improving the comfort and maneuverability of the vehicle.

Advantages

1. Non-linear stiffness characteristics: Compared with the linear stiffness of traditional coil springs, air springs have non-linear stiffness characteristics, and their stiffness characteristic curves can be designed according to the needs of the entire vehicle, in order to adapt to different loads and working conditions, thus providing better ride comfort and handling stability.

2. Height Adjustment Function: The air spring can adjust the body height by controlling the inflation volume to improve the vehicle's passability and stability. At the same time, lowering the body height also reduces the wind resistance coefficient and improves driving economy.

3. Vibration isolation and noise reduction: air springs have a significant improvement in isolating high-frequency vibration and noise compared to traditional steel springs, which can improve the quietness of the car and ride comfort.

4. Strong adaptability: air springs are able to adapt to changes in stiffness under different loads to meet the needs of heavy trucks, buses and other vehicles on the load carrying capacity.

5. Energy saving and consumption reduction: by optimizing the airflow under the vehicle body, air suspension can also achieve better battery cooling effect and improve fuel efficiency.

Uses

Automotive air springs are mainly used in automotive suspension systems to improve vehicle comfort and handling. As the level of vehicle intelligence increases, air suspension, combined with the vehicle's enhanced sensing ability, can anticipate road conditions and make active adjustments in advance, enabling the vehicle to maintain optimal driving conditions under different road conditions. In addition, air springs are widely used in self-adjusting air suspension systems for commercial automobiles, buses, railroad vehicles, machinery and equipment, and building foundations.
