BMW

The reliable air suspension system makes driving and off-roading as comfortable as possible.

What is the role of your car’s air suspension?

The air suspension supports the carbody   in relation to  the road and the  clearance variations. Clearance —is the distance between the lowest part of the car body and  the road surface. It is measured in the position when the   engine is located. The benefits of air suspension are:

• improved drive;
• better comfort;
• increased safety.

There are 3 types of air suspension — single-circuit, dual-circuit or four-circuit air suspension. The first one is installed on a single axis and is part of the base equipment of cargo vehicles. Its function is changing the clearance of the rear axis. The second one can be installed on one or two axis. In the first case, it allows for independent adjustment of the wheels; in the second case it functions as a single-circuit air suspension. The four-circuit air suspension is the most functional. It includes:

• compressor;
• air receiver;
• elastic elements (bellows, air-springs);
• air lines;
• sensors;
• electronic control unit.

This design allows for the passengers and the driver not to feel uncomfortable while the vehicle drives over potholes. It’s worth mentioning that main load falls on the elastic elements. The number of fluctuations and not the mileage determine their lifespan. However, the service life of the components can be extended with timely maintenance, removal of contaminants and regular inspection of the shock absorbers.

BMW's air suspension

Suspension in BMW is a connecting link between the vehicle’s body and the road’s surface. The car has a front and rear suspension. This includes elastic elements and details that determine the stiffness. The air suspension allows for the driver and passengers to feel comfortable when driving on rough roads. BMW is a car for sport performance, so it's often bought by speed lovers. This, however, damages the air springs.
