Working Principle of Air Suspension Bags

The air suspension bag uses the compressibility of gas to absorb vibration and impact. Its operation process includes air filling, height adjustment, vibration absorption and exhaust reduction. First, the air compressor injects compressed air into the air bag to expand it, increase the suspension height and support force. Then, the electronic control unit (ECU) automatically adjusts the amount of air in the air bag according to the vehicle speed, load and road conditions to achieve vehicle height adjustment. During driving, the air bag can buffer road bumps, reduce vibration transmission, and improve driving comfort. When the vehicle body needs to be lowered, the system releases some gas to allow the vehicle body to drop to enhance handling stability or facilitate passengers to get on and off the vehicle.

Main Role

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.
