Abstract

In a method of manufacturing an articulated shaft structure for the transfer of torque from a transmission to a differential drive, including a connecting flange having a tube section, a shaft plate disposed between the connecting flange and a transmission output flange and forming a torsion element for accommodating some articulation of the connecting flange relative to the output flange, and a centering part extending from the connecting flange for aligning the articulated shaft relative to a transmission shaft, the connecting flange is formed integrally with the tube section by deep-drawing in follow-on tool the tube section and, in the same manufacturing step, punching openings into the flange, and deep-drawing the centering part and pressing it into the tube section.
