Abstract
The invention relates to a pneumatic spring system which comprises a pneumatic spring cap and pneumatic cushioning bellows, a pneumatic spring piston with a lateral rolling surface and a base surface that is designed such that a multi-chamber system protrudes into the interior of the pneumatic spring piston. The aim of the invention is to provide a pneumatic spring piston that can be subjected to eccentric loads at a reduced weight and without a holding plate. The multi-chamber system and the fastening system are mounted in such a position that there is maximally one mirror plane perpendicular to the base surface of the pneumatic spring piston, in relation to the piston center axis, and that an eccentric rest surface of the pneumatic spring piston directly contacts the spring carrier.
