Air Suspension
When it comes to air-ride suspension, they come in several styles for both OE replacement and aftermarket upgrades. Some systems use an integrated air spring and shock absorber that replaces your customer’s metal springs with pressure-adjustable air springs (i.e., airbag). Using correctly sized air springs and properly calibrated shock absorbers offers ride characteristics similar to coilovers.

An air-suspension system consists of many different components. Components include an air compressor, air springs, pneumatic solenoid valves, height sensors, electronic control unit, air reservoir, air lines, pressure sensor and temperature sensor. The system may be designed for the rear air suspension only or for the entire vehicle.

While air-suspension systems are mostly used on high-end European cars, manufacturers have adapted them to many other vehicles such as SUVs and pickups to improve ride comfort and functionality. OEMs also discovered that air ride could improve fuel economy by lowering the car at highway speeds to reduce the drag coefficient.

Air Suspension Advantage
1. Air springs increase spring rate and vastly improve vehicle stability, that means a safer and more comfortable ride.
2. Soaks up bumps, reduces the frequency of vibration while driving on the road, prevents the damage of the other parts from the heavy loading vehicles.
3. The cushioning principle is adopted, the shock absorption performance is obviously improved, and the passenger comfort is improved.

Air Spring

air spring, load-carrying component of an air suspension system used on machines, automobiles, and buses. A system used on buses consists of an air compressor, an air-supply tank, leveling valves, check valves, bellows, and connecting piping. Basically, an air-spring bellows is a column of air confined within a rubber and fabric container that looks like an automobile tire or two or three tires stacked on top of one another. The check valves admit additional air to the bellows from the air-supply tank to maintain vehicle height when the load is increased, and the leveling valves vent excess air from the bellows when the vehicle rises because of unloading. The vehicle thus remains at a fixed height regardless of load. Although an air spring is flexible under normal loads, it becomes progressively stiffer when compressed under an increased load.
