Abstract

A rolling bellows for pneumatic cushioning or shock absorption of a vehicle. Such rolling bellows are stressed particularly severely during telescoping in the pressureless state during assembly and also under emergency condititions. In order to avoid the occurrence of tension cracks from such causes, the rolling bellows are provided in the region of the cylindrical curvature, and on the inner surface, with integrally formed-on raised surface portions.
