Pneumatic suspension by hands

Pneumatic suspension is a complex technical system that provides a reduction in the center of gravity of the car, which gives it greater stability in motion. Its use leads to the fact that the level of the ground clearance always remains unchanged, regardless of the quality of the roads and the load on the overall suspension system of the car.

Pneumatic suspension for any car has been designed and installed, based on the following reasons:

1. With the development of the automobile industry, the weight of the car is constantly decreasing, and its carrying capacity is increasing, which leads to the fact that the difference in weight between an empty and loaded car can reach one hundred percent or more.
2. Over the past 50 years, there has been a significant change in the speed of the car in the direction of its increase. This change led to the need to "tighten" the suspension to increase the stability and controllability of the machine while driving.
3. One of the most pressing problems of the entire history of the automotive industry continues to be the demand for improved ride comfort and a smoother ride.

All of the above led to a variety of engineering solutions, including the appearance in 1955 on the cars of the French company Citroen air suspensions. Today, this unit is already widely used on machines of different brands and sets, moreover, motorists have learned to install such a complicated technical system as a pneumatic suspension by their own hands, to improve and modernize it.

However, it should immediately be noted that the installation and repair of such a device as Air suspension, their own hands is very difficult. This is due, firstly, to the fact that it is difficult to buy the necessary equipment and spare parts for this type of work, on the one hand, and on the other, it is inappropriate, since this purchase is unlikely to pay for itself. Secondly, since these units are not on every car, so their repair can not be trusted by any SRT.

A conventional air suspension, including that installed on domestic cars, consists of cylinders filled with air, a receiver, sensors showing the level of pressure, a special compressor and an air line. The main role here is played by cylinders with air under high pressure, which ensure the elasticity of the entire system. At the same time, the cost of this unit is greatly influenced by what valves are used here - electrical or manual. The air suspension for VAZ differs from its foreign counterparts in relative simplicity and relatively low cost.

The pneumatic suspension for any car is established as a result of the following operations:

1. Creation of front pneumatic stands , which includes the collection of the structure from the shock absorber pillar, air bag, upper post and support bearing. However, there are some nuances here: in order to install an air suspension for the VAZ, among other things, a small piece of pipe, the diameter of which is equal to the diameter of the rack, will be required.
2. Installation of front pneumatic stands, which in its essence is an installation of a conventional spring rack.
3. Installation of air bags. When designing such a technical device as an air suspension, one must use the simplest types of air bags, for example, such as SS-5 or Contitech 2500.
4. Air suspension system. All the necessary elements of this technical device are located in the luggage compartment. This applies to the compressor, and to the valves, and to the receiver with pressure sensors. It is necessary to cut special covers covered with epoxy resin, which will protect the entire mechanism from moisture. In addition, it must be remembered that the high pressure relief valve should not rest on the floor, so it should be installed on special bars.

Pneumatic suspension with their own hands will not only help save considerable financial resources, but will also fully meet the design features of the car. This technical element will significantly increase the level of comfort when traveling in the car. An uncomplicated technical device will help alleviate the inconvenience of passing complex turns and uneven areas.
