Claim Text:
1. 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, wherein the elastomeric element is made of rubber and is vulcanized between the two piston parts; and wherein the first piston part is formed in two parts with a first and a second component, the first component being provided for fastening the air spring bellows and the rolling surface being arranged on the second component.
