Adjustable suspension plays a very important role in car culture. The hydraulic system has been used in the automotive industry for a long time. It is good and reliable, but the air suspension is simpler and more modern. In hydraulics, standard springs are the main element. Pneumatic elements are cylinders, called Air Bags in the United States, made of a flexible and durable type of rubber. They are filled to a specified volume with compressed air and are called pneumatic cushions. The volume of air in them can vary and the pneumatic system is based on this possibility.

The air suspension operates according to the following principle: as soon as the volume in the air cushion under air pressure reaches the maximum possible value, the height of the car's clearance will change. A receiver, paired with a compressor, is used to store and pump air.

If the pressure is too high, then the air is etched directly into the atmosphere, if it needs to be increased, then its supply from the receiver is turned on. At the same time, the air suspension on the VAZ and on other vehicles is controlledremotely. The driver gives an electrical signal, and at this time the air valve of the pneumatic element is activated accordingly.

The complexity of such a system lies in the fact that when the air has to be bled frequently, it is difficult to maintain the working air level in the receiver. But if you arrange an air suspension with your own hands, then you can install not one, but several compressors or choose a larger receiver, or you can install not one, but several receivers.

It is important that the air suspension has great advantages, since compared to the hydraulic suspension it is much softer, there is practically no roll when cornering, and when the passengers and the driver are suddenly braked, the inertia does not blow them off the seat. When driving on a good track, the clearance can be completely lowered down, and you can drive a well-stable car. It is also important that even with the maximum load of the vehicle, you can easily raise or lower the clearance. At the same time, air suspension is inexpensive and very easy to operate and maintain. As for the power supply, here the advantages over hydraulics are high, because pneumatics quietly operate on the basis of a standard battery, while hydraulics need additional power.

Those who are going to install pneumatics themselves may need to improve the suspension a little. So, on the spring type of suspensions, you have to leave only one longest spring. All pneumatics can fit in the luggagebranch or paint, issuing in the original style.

The air suspension also has disadvantages. It's her chugging sound of air escaping. Those who like to ride at high ground clearance and still have a good shake and jump while riding can stay true to hydraulics.
