Abstract: The invention concerns a driving disc for transmitting the torque from one drive unit to a hydrodynamic converter (2). The driving disc (5) has one leg (51) extending in radial direction and fastened on the output shaft (1) of the drive unit and one leg (52) extending in axial direction and fastened on supporting devices (4) of a housing (3) of the hydrodynamic converter (2). By recesses (10) spaced apart from each other in peripheral direction of the driving disc (5), there are formed in the leg (52) extending in axial direction bracket arrangements which serve to fasten the leg (52) extending in axial direction on supporting device (4) situated in the housing (3). The bracket arrangements are each formed by tongue-shaped brackets (11, 12; 11′, 12′) which seen in peripheral direction extend successively from both sides of the recess (10). The end areas of the brackets (11, 12; 11′, 12′) are each fastened on one supporting device (4).
