Abstract
A power transmission device, in particular for use in vehicles, having one input and at least one output, comprising a hydrodynamic component and a lockup clutch. The lockup clutch includes at least one friction surface arrangement which is coupled at least indirectly in a rotationally fixed manner with the input of the power transmission device, or is coupled in a rotationally fixed manner with the pump wheel, and can be brought into an operative connection with a second frictional surface arrangement which is connected to the output in a rotationally fixed manner. An actuating mechanism is assigned to the lockup clutch. The actuating mechanism forms one structural unit with a friction surface carrying element of the first friction surface arrangement, and is coupled in an axially movable and rotationally fixed manner with the input of the power transmission device, or with the connection between the input and the pump wheel.
