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.

Abstract: A hydrodynamic torque converter with a pump wheel, a turbine wheel, and a stator, which combine to form a hydrodynamic circuit, where the flow conditions in the hydrodynamic circuit can displace the turbine wheel axially toward the pump wheel when the converter is operating in pull mode and in the opposite direction when operating in push mode, where at least one axial bearing on the drive side of the freewheel and at least one drive-side thrust washer establish a working axial connection between the turbine wheel and a component of the freewheel.

Abstract: A hydrodynamic clutch device, particularly a hydrodynamic torque converter or fluid coupling, comprises a housing arrangement, a turbine wheel which is arranged in the housing arrangement so as to be rotatable with respect to the housing arrangement about an axis of rotation, a lockup clutch arrangement by means of which a torque-transmitting connection can be selectively produced between the housing arrangement and the turbine wheel, wherein the lockup clutch arrangement comprises a clutch element which is connected by a connection arrangement to the housing arrangement so as to be substantially fixed with respect to rotation but axially displaceable relative to it, wherein the connection arrangement comprises at least one elastically deformable connection element which is fixedly connected with the housing arrangement on the one hand and with the clutch element on the other hand.

Abstract: A hydrodynamic coupling device for producing a torque transmission connection between a drive unit and a transmission is provided including a first coupling device attached to the drive unit for coupling the hydrodynamic coupling device with the drive unit for transmitting a torque between the hydrodynamic coupling device and the drive unit and a second coupling device attached to the transmission for coupling the hydrodynamic coupling device with the transmission for transmitting a driving and/or braking torque between the hydrodynamic coupling device and the transmission. A method of making a hydrodynamic coupling device is also provided.

Abstract: A hydrodynamic clutch device, especially a hydrodynamic torque converter, includes a pump impeller installed in a housing, a turbine impeller having a turbine shell connected nonrotatably to a turbine hub, and possibly a stator. The turbine hub consists of several individually manufactured parts such as a sheet-metal parts, and the turbine shell is designed and mounted on the turbine hub so that it assumes some of the functions of the turbine hub, such as the sealing and guide functions.

Abstract: A connection arrangement for coupling a hydrodynamic torque converter to a rotating shaft so that the torque converter is fixed with respect to rotation relative to the rotating shaft includes at least one fastening element arranged at a converter housing. The at least one fastening element is arranged at the converter housing such that a fastening portion of the at least one fastening element meshes or interlocks in a positive engagement with a receiving portion of the converter housing.
