A composite suspension control arm shaft for motor vehicles includes two tubular longitudinal control arms connected through a torsion section having a V-shaped or U-shaped cross-section, wherein reinforcing sheet metal pieces are mounted in the transition areas between the torsion section and the longitudinal control arms for increasing the bending stiffness. The ends of the torsion section have a configuration which is adapted to the outer contour of the longitudinal control arms and the apex portions located at the ends extend to the upper sides of the longitudinal control arms, wherein the reinforcing sheet metal pieces are each welded with a leg thereof to the torsion section at the apex portion of the torsion section and with another leg to the length portion of the longitudinal control arm on the side of the wheel carrier, wherein the reinforcing sheet metal pieces are arranged so as to be inclined downwardly from the torsion section toward the end of the longitudinal control arm on the side of the wheel carrier, and wherein the reinforcing sheet metal pieces engage with end faces thereof around portions of a wheel carrier and are connected to the wheel carrier.

Composite suspension control arm shaft for motor vehicles

A method of manufacturing a composite front suspension control arm shaft for motor vehicles includes connecting two tubular longitudinal control arms to a transverse sectional member, wherein a connection portion adapted to the cross-sectional configuration of the ends of the transverse sectional member is produced at each longitudinal control arm, and wherein the ends of the transverse sectional member are positioned in an assembly position relative to the connection portions and are secured by welding thereto. The composite front suspension control arm shaft includes two tubular longitudinal control arms connected to a transverse sectional member, wherein the first length portion of each longitudinal control arm adjacent the wheel carrier is of rectangular configuration, wherein the width of the rectangular length portion is greater than the height of the length portion and a second length portion of each longitudinal control arm to be coupled to the support frame is of rectangular configuration, wherein the height of the second rectangular length portion is greater than its width, and wherein each longitudinal control arm has a connection portion adapted to the cross-sectional configuration of the ends of the transverse sectional member.
