Abstract
A pneumatic spring for utility vehicles comprising a rolling bellows and a rolling piston. The rolling bellows has at least one bead-like plug-on edge. The rolling piston is of unipartite form and includes an interior space constantly exchanging air with an air chamber enclosed by the rolling bellows. At the plug-on edge, the rolling bellows has a sealing bead with an inelastic bead core for connection to the rolling piston. The fastening of the plug-on edge to the rolling piston, with position securing action and sealing action, is disposed on an inner side of a rolling piston edge.
