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.
Most air suspension systems now come with an on-board compressor. The compressor is an electric pump feeding air to the bags through a series of compressed air lines. The compressor is generally mounted on the vehicle's frame, or in the trunk. The vast majority of compressors come with an attached drier. The compressor works by drawing outside air into the pump, compressing it and moving it to the bags. Outside air is often laden with moisture, and moisture can wreak havoc in a closed system. The drier uses a substance known as a desiccant to absorb as much moisture from the air as possible before the air is sent through the system.
Features
1.Vulcanized, heavy-duty rubber air springs at each of the vehicle's wheels
2.An air compressor in the vehicle's trunk or under the hood of the vehicle
3.A storage tank for compressed air, which allows you to store air at around an average of 150 PSI
4.Valve blocks which direct air to the four springs from the storage reservoir through a set of solenoids, valves, and o-rings
5.ECAS computer that communicates between the vehicle's main computer to calculate where to direct air pressure
6.Air pipes connecting from the storage tank to the air springs that channel the flow of air throughout the suspension system
7.A desiccant-filled drier canister to keep the internal recesses of the system dry.
8.Front Left air suspension spring 7L8616039D for Audi Q7 is protected by an aluminum can and dust baffle to keep out debris and is assembled 9.with heavy-duty crimping rings, seals, bump stop and connector valve.
What is an air suspension struts?
Air suspension is a type of vehicle suspension powered by an electric or engine-driven air pump or compressor. This compressor pumps the air into a flexible bellows, usually made from textile-reinforced rubber. Unlike hydropneumatic suspension, which offers many similar features, air suspension does not use pressurized liquid, but pressurized air. The air pressure inflates the bellows, and raises the chassis from the axle.
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.
