Abstract
A rolling-lobe air spring is made of elastomeric material and includes a reinforcement layer made of rubberized textile cord fabric layers. The reinforcement layer extends over the length of the flexible member of the air spring. The cord threads of the textile cord fabric layers are arranged so that they are inclined relative to the peripheral direction of the flexible member. During operation, a rolling lobe is formed which changes during spring operation. The reinforcement layer includes three rubberized cord fabric layers (21, 22, 23) one atop the other. This provides a rolling-lobe air spring having a longer service life at higher internal pressures and smaller roll-off radii in the rolling lobe. The threads of the middle cord fabric layer 22 are arranged so as to cross the threads of the first and third layers. The middle cord fabric layer 22 has a strength which corresponds to the sum of the strengths of the first and third layers.
