  • Roll-off piston for an air spring rolling-lobe flexible member
    Patent number: 9334916
    Abstract: A roll-off piston for an air spring rolling-lobe flexible member, the interior of the roll-off piston is connected to the interior of the air spring. The roll-off piston includes two parts, namely, a pot-shaped piston lower part and a piston upper part connected in an air-tight manner to the lower part. A support for a stop buffer is integrated in the roll-off piston. The support includes two interacting parts, of which one part is configured as part of the piston upper part and the other part is configured as part of the pot-shaped lower part and extends from the base thereof. Both support parts interact in order to absorb forces acting substantially axially.
