The Air Suspension Springs are the core component of the air suspension system. They use the elastic properties of compressed air to replace traditional metal springs. They are used to support the body, cushion vibration, and adjust the height of the vehicle. Its structure is usually composed of flexible rubber air bags, internal pistons or rolls, which are dynamically adjusted by charging and discharging air.
The air bag has multiple functions. It absorbs vibrations and noise, enhancing ride comfort. By adjusting air pressure, it improves vehicle stability during cornering, braking, or under load. It automatically adapts to load changes, vital for heavy trucks and buses. It also reduces fatigue wear on other parts, extending the service life. Environmentally, compared to steel springs, air-cushioned airpacks are lighter and contribute to lower fuel consumption and emissions.
