The Key Components of an Air Suspension System

Understanding the components is key to understanding how these systems work. The core of any air suspension system includes the air bags themselves, which are the flexible, air-filled cushions that replace or work alongside traditional springs. Then, you've got the air compressor, which is essentially a pump that fills the air bags with compressed air. It's often electrically powered and can be mounted on the vehicle. Air lines and fittings connect the compressor to the air bags, allowing the air to flow between them. A control system, which can range from simple manual valves to sophisticated electronic setups, manages the air pressure in the bags. Height sensors are sometimes used to monitor the vehicle's ride height and automatically adjust the air pressure to maintain a consistent level. Finally, dampers (or shock absorbers) are used to control the movement of the vehicle's suspension. When these components work in harmony, they provide a smooth and controlled ride, improving both comfort and performance. Knowing these parts will help you troubleshoot and maintain your AG400 suspension air bag system effectively.
