A roll-off piston made of plastic is for an air spring rolling-lobe flexible member () of the air spring. The roll-off piston () is configured as a plunge piston and has a preferably central support () for a stop buffer () acting in an axial direction of the air spring. The support () is preferably made of steel and can be received in a recess in the roll-off piston. The recess is of complementary configuration to the shape of the support and can be connected to the piston.

Roll-off piston for an air spring rolling-lobe flexible member

An air spring for commercial vehicles includes a rolling-lobe flexible member which is made of an elastomeric material and which at one end thereof is fastened to a first attachment part and at the other end thereof is fastened to a second attachment part in the form of a roll-off piston. The ends of the rolling-lobe flexible member each have a fastening bead which is reinforced in each case by a bead core. At least one of the two bead cores consists of plastic material. In order to achieve greater strength of the fastening bead, the bead core or the bead cores include a multiply-wound, flat profile strip made of glass-fiber-reinforced plastic material.
