Luftfjedrene

Luftfjedrene, which translates to "air springs" in English, are a type of suspension component that utilizes compressed air to support a vehicle's load and absorb shocks. Unlike traditional coil springs made of metal, air springs consist of a flexible rubber or polyurethane bellows that encloses a volume of air. This air is compressed by the vehicle's weight, and its pressure can be adjusted to alter the spring rate and ride height.

The system typically includes an air compressor, an air reservoir, an air spring unit, and a control system. The control system, often managed by sensors, regulates the amount of air entering or leaving the air spring to maintain a desired ride height or to adapt to changing road conditions. This allows for a more comfortable and adjustable ride compared to conventional suspension systems.

Air springs are commonly found in heavy-duty trucks, buses, and luxury cars. In commercial vehicles, they are crucial for maintaining a consistent ride height regardless of load variations, which is important for vehicle stability and brake performance. For passenger cars, air springs offer enhanced comfort, improved handling, and the ability to adjust the vehicle's stance for better aerodynamics or obstacle clearance. The technology can also be used in specialized applications like industrial machinery and railway vehicles.
