Air suspension is a type of vehicle suspension powered by an engine driven or electric air pump or compressor. This pump pressurizes the air, using compressed air as a spring. Air suspension is for poseurs, not racers, so it has no place in your musclecar, right? Air suspension is powered by an electric air pump, compressor or engine driven. A pump pressurizes the air, using compressed air as a spring.
Air suspension is, of course, an option at extra cost . Air suspension is too bulky and too expensive for medium and small sized cars. The alternative solution is to control the flow of oil inside traditional shock absorbers.These systems are lower in cost, but cannot offer such good comfort performance. Air suspension is used to keep the rear level at all times. The air springs are mounted on the axle spring seats and to the frame upper spring seats.
Air suspension is becoming ever more common as the secondary suspension system on modern passenger train cars, as air-sprung chassis offer optimum riding comfort. The crucial benefit of the air spring when it comes to comfort is that its suspension properties can be adjusted according to the load, with the spring’s height kept at a constant value by charging and exhausting the bellows. Air suspension is standard on the LS 430 and optional on the RX 300. On both models, each of the four suspension units is continuously adjusted by computer-controlled electronics to suit the car’s speed and the road surface.
