Abstract: A hydrodynamic torque converter comprises a pump wheel, a turbine wheel, and a stator, which combine to form a hydrodynamic circuit. The stator is centered with respect to an axis of rotation and has a freewheel hub so that it can be mounted on a freewheel, which hub is carried by a radially outer freewheel component and is connected by means of a transmission element part to a radially inner freewheel component with freedom of relative rotation. At least one first freewheel component has a damping device, which serves to reduce the ability of this freewheel component to rotate relative to the other, second freewheel component and which for this purpose can be brought into working connection with the second freewheel component.
