The invention relates to an integral motor vehicle rear axle of the twist-beam axle type, which comprises an opposed pair of longitudinal control arms (2) of a high flexural strength and torsional stiffness for carrying a wheel carrier for a wheel, and a transverse strut (3) which is resistant to bending but resilient relative to torsional stress and which comprises a profiled cross-section changing the position of the shear center. The transverse strut (3) consists of an extruded aluminum profile with an extrusion structure extending in the longitudinal direction of the transverse strut. A method of producing a motor vehicle rear axle of the twist-beam axle type using transverse struts and longitudinal control arms consists in joining the longitudinal control arms (2) with a transverse carrier or strut (3) which, at each end, comprises a bore, opening or bonding surface extending transversely to the longitudinal axis, and in connecting said longitudinal control arms in a form-fitting and force-locking way, such as by hydro-forming, welding or similar methods.

Twist beam axle and method of producing same

A side impact protection member for motor vehicle doors with a sheet metal strip of a profiled cross section, which has at least one longitudinally extending bead and has material strips joining the bead on both sides. The sheet metal strip has essentially flat ends for fastening to the motor vehicle door, and the height of the bead decreases continuously in the transition area toward the flat ends of the sheet metal strip. The sheet metal strip is formed of a cold-formable, high-strength steel material with a yield point of at least 980 N/mm.sup.2 and a tensile strength of about 1,250 N/mm.sup.2. The bottom of the bead has an essentially semicircular profile, and outer material strips of the sheet metal strip have edge recesses, which extend at least to the bead, directly adjoining the transition area.
