Abstract
A vehicle air spring with an elastomer material air-tight tensioned air spring bellows arranged between an air spring cover and rolling piston. The air spring bellows delimiting, with the air spring cover and the air spring rolling piston, a working chamber filled with compressed air. The air spring bellows rolling away under formation of a rolling fold on the air spring rolling piston and fastening to the air spring cover under formation of a second fold, and having an elastomer element provided as an anti-roughness bearing. The elastomer element is arranged between a first and second piston part of the air spring rolling piston, the second part arranged coaxially to the first. The rolling surface for the air spring bellows is provided on the first piston part and on which the air spring bellows is fastened by a clamping element. The second piston part is mountable on a vehicle chassis.
