What is air suspension?

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.

HONGGU 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 automotically 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.

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 Suspension Work

Instead of the metal spring mechanism, strong rubber bags act as air containers. The bags are then connected to an air compressor and an air reservoir. The compressor does the job of inflating and deflating the bags, which is how the car gets raised and lowered. The resulting effects are a smoother ride and versatility in performance. These systems come with a control unit that's located inside the car to give the driver complete control over the system. As this set-up is just a modification of a traditional system, changing how your car performs is just a matter of purchasing a kit.

Air spring

Air springs have been used in heavy duty vehicle suspension systems for nearly a century, where they have been able to provide usefulness by taking advantage of the compressed air required for vehicle braking systems. Air springs have provided a two-fold advantage over mechanical leaf- or coil-springs. One advantage with air suspension is the extra comfort provided by being able to vary the air pressure inside the spring, which changes the spring rate, and therefore, ride quality. Additionally, because variable control over air pressure adjusts the deck or trailer height, aligning loading docks to the level of the deck is possible when dock plates are unavailable.

Air Springs Information

Air springs contain a column of air in an elastomeric bellow or sleeve to provide suspension, isolation, or actuation. Commonly found in vehicle suspension systems, occasionally in conjunction with a coil spring, they are also used to insulate vibration in machinery and as linear or angular actuators.
