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.

How do air struts work?

An air suspension system is a style of vehicle suspension that's powered by an electric pump or compressor that pumps air into flexible bellows that are typically made out of a textile-reinforced type of rubber. ... A compressor inflates the bags to a certain pressure in order to behave like springs.

Shock absorbers and how they work
The shock absorbers reduce and slow down the vibrations from the springs, which is why technically they are correctly referred to as vibration dampers. Vibration dampers convert kinetic energy into thermal energy through fluid friction. This involves the flow of oil being slowed down by the valve passages inside the damper.

Air Spring

As air is directed into air springs, the bladders allow them to expand in a linear fashion, which permits them to be used as force-developing actuators, like pneumatic cylinders, and as such, rod attachments are available to mimic the function of them. Most often, however, an air actuator is simply two end plates connected by a bladder, and as they’re pressurized, force pushes the plates away from each other. As linear actuators, they can provide up to 35 tons of force, making them useful in various press applications, such as a forming press or small stamping press. Air actuators are also excellent for constant force applications, such as pulley tensioners or drum roller compression devices. All air springs are single-acting, unless they are coupled together so one extends while the other retracts.
