Abstract
An air spring rolling-lobe flexible member is made of elastomeric material and has at least two layers of intersecting reinforcement filaments. The reinforcement filaments are arranged in an essentially parallel manner to each other at an angle between 40° and 80° to the direction of the periphery of the rolling-lobe flexible member. At least one component quantity of the reinforcement filaments (1, 2) within one layer exhibits another strength compared to the remaining component quantity thereof.
