Twist beam axle for a motor vehicle

A twist beam axle for a motor vehicle, the twist beam axle comprising:

• a torsion profile;
• and
• two trailing arms connected by the torsion profile,
• wherein the torsion profile is integrally joined at each of longitudinal end sections thereof to a corresponding trailing arm of the two trailing arms by a weld seam,
• wherein each of the longitudinal end sections has a relief bead in proximity to the weld seam by which the longitudinal end section is joined to the corresponding trailing arm,
• wherein the relief bead has a longitudinal extension and is oriented transversely to a course of the weld seam in a direction of the longitudinal extension,
• wherein the weld seam has a weld seam section in which highest stresses occur upon the torsion profile being subjected to a bending moment,
• wherein the relief bead has a width on a side thereof oriented towards the weld seam, and the width of the relief bead corresponds to a length of the weld seam section,
• wherein the weld seam section in which the highest stresses occur upon the torsion profile being subjected to the bending moment corresponds to a transition area of the weld seam from a substantially vertical course to a substantially horizontal course with respect to the corresponding trailing arm, and
• wherein the relief bead is arranged laterally offset with respect to a central longitudinal axis of the torsion profile, and the torsion profile has a double-walled U-shaped middle section in cross section which widens towards the longitudinal end sections to form an oval-shaped profile.
