Abstract (en)

[origin: WO2005098261A1] Disclosed are U-bellows for a pneumatic spring, which are made of elastomeric material and comprise a tensile support arrangement that is embedded in the bellows wall (1), extends along the entire length of the bellows, and is composed of rubber-coated cord fabric layers (3, 4). Said U-bellows for a pneumatic spring encompass a non-symmetric tensile support arrangement in which the single outer fabric layer (3) or the several outer fabric layers is/are provided with a stress-elongation behavior that is different from that of the single inner fabric layer (4) or the several inner fabric layers.
