Abstract

The invention relates to an air spring module having an air spring and a shock absorber for the suspension and damping of vibrations of a motor vehicle chassis. The air spring has a rolling bellows which is fastened to an air spring cover and a rolling piston. The rolling bellows at least partially delimits a first working space filled with compressed air. At least two working spaces are provided in the rolling piston, which are separated from one another by a partition and connectable to the first working space via switchable valves arranged in the rolling piston. In order to achieve simple production and installation as well as a low overall height, the rolling piston has at least two working spaces which are arranged adjacent to one another.
