Abstract

A hydrodynamic torque converter is embodied with a converter housing that, on its side facing a drive, has a substantially radially-running primary flange. Attached to the primary flange are a central pin for mounting and a holder for holding the converter housing on the drive, as well as a housing hub for mounting a transmission shaft of an output. At least one of the connecting elements on the primary flange (i.e., the holder, the housing hub and the central pin) is connected to the primary flange by an outward pressing. The holder, housing hub and central pin respectively establish a connection between the primary flange and the drive or output. This connection to the primary flange is created by material displacement into an opening in the connecting element in question, which opening is located on the side facing away from the connection. A rear-gripping device that grips behind the rear side of the connecting element is created at the free end of the outward pressing by means of material compression in the opposite direction and serves as to axially secure the connection of the respective components to each other.
