Abstract
A hydrodynamic clutch device comprises an impeller wheel with a plurality of impeller wheel blades arranged successively in circumferential direction about an axis of rotation, a turbine wheel which is located axially opposite the impeller wheel and which has a plurality of turbine wheel blades arranged successively in circumferential direction, a stator wheel with a plurality of stator wheel blades which are arranged successively in circumferential direction in an area between the impeller wheel blades and the turbine wheel blades and are supported on a blade carrier. The stator wheel blades, the impeller wheel blades and the turbine wheel blades define a fluid circulation zone extending substantially annularly about the axis of rotation. A torsional vibration damper arrangement has a damper element arrangement which, at least in some areas, is arranged radially inside the fluid circulation zone and overlaps axially with the fluid circulation zone. The blade carrier is shaped in such a way that it conforms at least partially to an outer contour of the damper element arrangement.
