The Compressor Air Springs Require a Compressor to Constantly Run

The Compressor Air springs require a compressor to constantly run. The air compressor turns a turbine or screw at a high speed, forcing pressurized air into a reservoir. The air compressor is powered by an electric motor, which is driven by power from the vehicle's alternator. The reservoir has a pressure detector, which keeps the air at a constant pressure. If the air pressure in the system drops or rises above the ideal pressure, the compressor will speed or slow to maintain constant pressure. Air Springs Each wheel has its own air spring. The air spring can be a pressurized air bag, or a piston filled with compressed air. When the car encounters a bump, the wheel pushes down on the air spring. The spring resists the motion, absorbing some of the force from the bump. This makes the ride more comfortable and also helps to keep the wheels in contact with the road. Controlling the Springs Many vehicles with air springs have individual controls on each wheel, which can control the pressure for a better ride. For example, when the vehicle turns, the controls will increase the pressure on the outside springs, preventing the vehicle from rocking as much. In some cases, the springs can be adjusted together to allow the vehicle to raise and lower. Buses can be lowered to make it easier to get in, for example. There are also cars with adjustable ride height, which allows them to be raised for going off-road and lowered for normal driving.
