摘要

The invention relates to an air spring for commercial vehicles, comprising a rolling lobe which is made of an elastomeric material and which at one end thereof is fastened to a first connecting part and at the other end thereof is fastened to a second connecting part in the form of a rolling piston. The ends of the rolling lobe each have a fastening bead, which is reinforced in each case by a bead core. At least one of the two bead cores consists of plastic material. In order to achieve greater strength of the fastening bead, the bead core consists, or the bead cores (11) consist of a multiple-wound, flat profile strand (12) made of glass fiber reinforced plastic material.
