ABSTRACT:
An axially flexible drive disc of sheet-metal for vehicle propulsion includes a centrally disposed flange for attachment to the end of the drive shaft of the vehicle propulsion engine and is connected at its external circumference at a few, preferably three, fastening points, located evenly distributed around the periphery, to the input element of the adjacent gearbox. The gear box includes a hydrodynamic torque converter as the input element with the converter housing simultaneously assuming the flywheel function for the vehicle propulsion engine. In order to increase the strength of the drive disc with respect to axial fatigue loads, to smooth offset and swash and to reduce frettage corrosion at the fastening elements, the force path from the central flange connection to the radially outwardly located fastening points is given a spiral shape to assure greater bending lengths, by kidney-shaped cutouts disposed between the fastening points and the flange connection so that, as a rough approximation, T-shaped spring elements are left between neighboring cutouts.
