Air suspension is a type of vehicle suspension system that uses air-filled bags instead of traditional metal springs. These air bags can be inflated or deflated to adjust the vehicle's height and ride quality, providing a smoother and more comfortable driving experience. This system is commonly found in luxury cars, trucks, and buses. The main components of air suspension include the air compressor, air bags, and control system. The air compressor pumps air into the bags, while the control system monitors and adjusts the air pressure based on load and driving conditions. This technology enhances stability and handling, especially when carrying heavy loads.
