Abstract

An air spring with an air spring rolling bellows made of elastomer material with reinforcing layers embedded within the rolling bellows wall, the air spring being clamped in between a sprung and an unsprung mass, wherein the rolling bellows comprises, within its wall at a first bellows end, a tubular or cylindrical wall reinforcement which extends in a longitudinal direction of the rolling bellows and which is formed in addition to the reinforcing layers, said wall reinforcement extending over an end-side partial length of the rolling bellows and imparting such a dimensional stability to the rolling bellows there that, during operation, the rolling bellows rolls, by way of its wall parts located outside of the additional wall reinforcement, on the outer side of the end-side partial length, with the formation of a rolling fold.
