Air spring
The air spring — or airbag — is the core component of an air suspension system. It supports the vehicle’s weight while absorbing shocks and road vibrations, ensuring comfort and consistent ride height.
An air spring is a flexible rubber element inflated with compressed air, used in place of conventional steel springs on many commercial vehicles. It adjusts to changing loads and driving conditions, maintaining optimal chassis height and smooth ride quality. Air springs are often paired with height control valves for automatic regulation.
By cushioning the impact of road irregularities, air springs protect both the cargo and the chassis from excessive stress. They improve vehicle stability, extend tire life, and reduce wear on suspension components. They’re critical in applications where ride comfort and load adaptability are top priorities.
Air spring failure can lead to a tilted stance, harsh ride, increased tire wear, or handling issues. Common causes include air leaks, rubber fatigue, aging, or damage due to overloading or external abrasion.
