Abstract
A transverse beam forming an at least indirect component of a composite suspension control arm shaft has over a substantial part of its length a trough-shaped torsion portion with a U-shaped or V-shaped cross-section formed by chipless deformation of a tubular hollow section, end portions having a circular cross-section and intermediate portions with a continuously changing cross-section from the end portions to the torsion portion, wherein the double walls of the torsion portion have in the transition areas from the torsion portion to the intermediate portions transversely directed embossments or impressions at the deepest point of the torsion portion, wherein the embossments or impressions engage in each other. Axially formed transverse webs are provided at the transitions from the end portions to the intermediate portions, wherein the transverse webs frontally face the torsion portion, extend essentially radially relative to the longitudinal axis and are formed from the bottom walls of the intermediate portions.
