Abstract:
A composite suspension control arm shaft for motor vehicles, the control arm shaft comprising two tubular longitudinal control arms and a torsion section having a V-shaped or U-shaped cross-section connecting the two tubular longitudinal control arms, wherein flat reinforcing sheet metal pieces are mounted in transition areas between the torsion section and the longitudinal control arms for increasing bending stiffness, the torsion section having ends with a configuration matching to an outer contour of the longitudinal control arm and an apex portion located at the end of the torsion section extending to an upper side of the longitudinal control arm, wherein each reinforcing sheet metal piece is welded with a first leg thereof to the torsion section at the apex portion thereof and with a second leg to a length portion of the longitudinal control arm on the side of a wheel carrier, wherein the reinforcing sheet metal piece is mounted so as to be inclined downwardly from the torsion section toward an end of the longitudinal control arm on the side of the wheel carrier, an wherein the reinforcing sheet metal piece engages with an end face thereof around portions of the wheel carrier and is connected to the wheel carrier.
