Abstract
The invention is directed to a rolling-lobe air spring having a flexible member made of elastomeric material. The flexible member defines the wall of the air spring and includes a reinforcement layer with two mutually-crossing cord-fabric layers. A rolling lobe is formed during the operating state of the air spring and changes with the reciprocating air spring action. An additional rubberized double-layer fabric having two mutually-crossing cord layers is arranged in the flexible member of the air spring in order to reduce the installation space needed for accommodating the air spring. This additional double-layer fabric extends directly from the clamped end region which lies opposite the rolling lobe and extends in the direction of the longitudinal axis of the air spring or only partially over the non-rolling region of the flexible member. The thread angle of the additional cord-fabric layers is less than the thread angle of the reinforcement layer.
