Abstract

A torsional vibration damper for a hydrodynamic torque converter is provided with at least one input part and an output part, which is given the ability to move relative to the input part by stored-energy elements, where the output part is designed as a hub disk, which is connected nonrotatably to a hub centered on a transmission input shaft. The hub disk extends radially inward to the area of the outside circumference of the hub, where it is connected directly to the hub.
