Air Suspension System

As a starting point, it is important to discuss what is air suspension and how does it differ from traditional suspension systems? The main difference between a traditional shock or strut is that they have a dampening mechanism set to a certain ride control feel while an air suspension system uses an air compressor in combination with air struts and suspension air bags to control the feel of the ride.

Air suspension has several advantages over traditional shocks and struts. The first is that the ride quality is often controlled by the driver of the vehicle. Therefore, if you want a softer ride you can set your air suspension system to deliver that and vice versa if you are looking for a stiffer, rougher ride. The second advantage is that you can control ride height, some systems are advanced in that they automatically control this for you. The final advantage of an air suspension system is weight management. If you load the back of your SUV with a large amount of groceries from the store, the air suspension system either automatically adjusts to handle it or you can manually adjust it. For traditional shocks and struts the level of rebound is set and therefore no matter what the weight of your load is, you have to stick with it. This often creates a sagging rear end when carrying a heavy load.

While an air suspension system is more complex, the advantages are clear. The system is comprised of a central air suspension compressor as well as air struts within an air bag at each wheel. The air compressor pressurised the air struts as needed to control the feel. Other components can be seen in the diagram above, all of which are mainly air lines to transfer pressure and driers (filter) to complete the system.

As the car's suspension system is an often-overlooked area. From a comfort and safety standpoint, your car's suspension is integral to how your car drives. Shock absorbers and coil springs help absorb and direct road force, maintaining wheel oscillation, jounce and rebound.
However, every time you add or take away weight to a vehicle, speed up or slow down, or turn left or right, this challenges what the shock absorbers and springs are capable of. Traditional stock shocks and springs are designed and installed with only a fixed set of situations in mind.
Honggu Air suspension systems essentially replace a vehicle's coil springs with air springs. The air springs are simply tough rubber and plastic bags inflated to a certain pressure and height to mimic the coil springs. But the similarities end there. By adding in an on-board air compressor, sensors and electronic controls, today's air suspension systems provide several advantages over all-metal, conventional springs, including near-instant tuning, and the ability to adapt handling to different situations and vary load capability.
Whether the system is manual or electronic, or installed by a weekend mechanic or a seasoned tech, air suspension can lower a car to improve its street cred, even out a heavy payload, or simply improve the ride of a vintage Detroit metal street monster.
