Function shown using example of a front axle suspension strut.

The vehicle weight is borne by the compressible air enclosed in the air bellows of the suspension struts. The air is located in the air chamber. The air spring bellows designed as a sleeve air spring is made of rubber. In the event of dynamic loading while driving, the air bellows unrolls parallel to the McPherson axle and thus ensures the required spring travel.

The suspension strut rolling zone is sealed to the outside using a protective boot to protect against dirt. Lifting/lowering the vehicle level takes place by increasing/reducing the air pressure in the air chamber, which results in a shortening/lengthening of the front axle suspension strut.
