The cross-member () comprises first and second beam elements () having an open cross-section and firmly secured to each other so as to enclose a closed cross-section chamber () having such shape and sizes as to provide the cross-member () with the desired torsional stiffness. A free edge () of the first beam element () is firmly secured to the outer surface of an intermediate portion () of the second beam element () and a free edge () of the second beam element () is firmly secured to the inner surface of an intermediate portion () of the first beam element (). The two beam elements () are advantageously made as stamped sheet metal pieces.

Cross-member for a twist-beam axle rear suspension for a motor vehicle

A trailing arm for a rear independent suspension of a motor vehicle. The arm () includes a beam-like mounting structure () and a plurality of components including a first component () for the mounting of a first bush () for articulated connection of the trailing arm () to the vehicle structure, a second component () for support of a wheel-carrying spindle; a third component () for the mounting of a second bush () for articulated connection of the trailing arm () to a first rod (), a fourth component () for the mounting of a third bush () for articulated connection of the trailing arm () to a second rod (), a fifth component () for support of a spring, a sixth component () for connection of the trailing arm () to a shock absorber (), and a seventh component () for connection of the trailing arm () to a torsion bar ().
