Air springs are flexible devices that use compressed air to support loads and absorb shocks. They are commonly found in vehicles, such as trucks and buses, where they help improve ride quality by reducing the impact of bumps and uneven surfaces. Air springs can adjust their height and stiffness based on the load, providing a smoother driving experience. These springs consist of an air-filled rubber bladder that expands and contracts as needed. When the vehicle carries more weight, the air pressure increases, allowing the spring to maintain stability. This technology is also used in industrial machinery and air suspension systems for enhanced performance and comfort.
