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.
An air spring for vehicles, having an air spring bellows made of elastomeric material clamped in an airtight manner between an air spring cover and an air spring rolling piston, which air spring bellows delimits with the air spring cover and the air spring rolling piston a working chamber filled with compressed air, rolls on the air spring rolling piston while forming a rolling fold and is fastened to the air spring cover while forming a second fold, and having an elastomeric element which is provided as an anti-harshness mount, wherein the elastomeric element is arranged between a first piston part and a second piston part, coaxial therewith, of the air spring rolling piston, the first piston part and the second piston part being separate structures that are coupled together by way of the elastomeric element, the first piston part having a radially-inward facing surface and the second piston part having a radially-outward facing surface with the elastomeric element extending from the radially-inward facing surface of the first piston part to the radially-outward facing surface of the second piston part, the rolling surface for the air spring bellows being provided opposite the radially-inward facing surface on the first piston part and the air spring bellows being fastened by means of a clamping element, and the second piston part being mountable on a mounting surface of a vehicle body,
An air spring for vehicles, having an air spring bellows made of elastomeric material clamped in an airtight manner between an air spring cover and an air spring rolling piston, which air spring bellows delimits with the air spring cover and the air spring rolling piston a working chamber filled with compressed air, rolls on the air spring rolling piston while forming a rolling fold and is fastened to the air spring cover while forming a second fold, and having an elastomeric element which is provided as an anti-harshness mount, wherein the elastomeric element is arranged between a first piston part and a second piston part, coaxial therewith, of the air spring rolling piston, the first piston part and the second piston part being separate structures that are coupled together by way of the elastomeric element, the rolling surface for the air spring bellows being provided on the first piston part and the air spring bellows being fastened by means of a clamping element, and the second piston part being mountable on a mounting surface of a vehicle body,
