- Air Spring
HGV air springs, also known as air bags, are a type of suspension system commonly used in heavy goods vehicles (HGVs) such as trucks and buses. These air springs consist of a flexible bellows or bag filled with pressurized air that is connected to the vehicle's frame and axle. The air pressure in the spring can be adjusted to provide a smooth ride and to accommodate varying loads. Air springs also help to improve stability and handling, and can help to reduce wear and tear on the vehicle's suspension components.
