Abstract: A twist beam axle for a wheel suspension of a motor vehicle. The twist beam axle has two trailing arms and a torsional profile having prismatic-shaped end sections with a noncircular cross-section. One trailing arm is connected to one torsional profile end section in each case. The trailing arms have a receiving recess having a shape corresponding to that of the outer surface of the torsional profile end section. An inwardly pressed plug is disposed in the interior of each torsional profile end section. The twist beam axle ensures permanent transfers high bending moments and torques between the trailing arms and the torsional profile without a welded joint. Different classes of materials can be used for the torsional profile and trailing arms, or can be connected to one another. The twist beam axle generally makes it possible to use large-volume, thin-walled and, therefore, weight-saving torsional profiles.
