Abstract: A bridging clutch is installed in a fluid medium-filled housing of a hydrodynamic coupling device located between a drive shaft and a transmission input shaft, the coupling device also containing a pump wheel and a turbine wheel. The bridging clutch is provided with a piston, which, when moved into a first axial position, brings at least one friction element into working connection with at least one friction surface, and when moved into a second axial position, at least partially releases this working connection, and with a torsional vibration damper, which is designed with at least one drive element and with at least one takeoff element, at least one of which has openings for circumferential springs and actuating areas for these springs. At least one of the takeoff elements acts a carrier element for the turbine wheel, which is held otherwise without radial support in the housing.

Abstract: A hydrodynamic coupling device having a housing which is, or can be, filled with hydraulic fluid, a turbine wheel which is rotatably arranged in the housing and is, or can be, connected to an output shaft for joint rotation, and a sliding bearing arrangement which the turbine wheel is rotatably mounted relative to the housing, and which has a hydraulic fluid channel arrangement for the passage of hydraulic fluid from radially outside to radially inside relative to the region of the output shaft, or vice versa.

Abstract: A hydrodynamic torque converter is embodied with a converter housing that, on its side facing a drive, has a substantially radially-running primary flange. Attached to the primary flange are a central pin for mounting and a holder for holding the converter housing on the drive, as well as a housing hub for mounting a transmission shaft of an output. At least one of the connecting elements on the primary flange (i.e., the holder, the housing hub and the central pin) is connected to the primary flange by an outward pressing. The holder, housing hub and central pin respectively establish a connection between the primary flange and the drive or output. This connection to the primary flange is created by material displacement into an opening in the connecting element in question, which opening is located on the side facing away from the connection.

Abstract: A hydrodynamic torque converter a hydrodynamic circuit has at least a pump impeller and a turbine wheel. The turbine wheel has a turbine shell with a blading and a turbine hub which is in rotary connection with an output shaft. The turbine shell extends radially inward between an extension region of axial abutments and is provided with stiffeners.

Abstract: A housing component for a hydrodynamic clutch device, especially a hydrodynamic torque converter, possesses a friction surface region for a converter lock-up clutch of the clutch device on a first side which is positionable for facing the interior of the clutch device. This housing component is formed by, at least in the region of the friction surface region, the reshaping of a metal component. On a second side of the housing component lying opposite to the first side a surface structuring is formed in a region corresponding to the friction surface region by reshaping of the metal component to form the friction surface region.

Abstract: A bridge coupling on a hydrodynamic torque converter is embodied with an axially movable piston arranged on a radial bearing. In one operating position, the piston can be brought into active connection with a support surface of a radial flange of the converter housing via at least one friction lining. The piston executes its axial movement under the influence of an axially elastic element integrated in the radial bearing and having an elastomer substantially deformable in the axial direction.

Abstract: A bridge coupling on a hydrodynamic converter comprises a piston deflectable in the axial direction and connectable via at least one friction lining to the converter housing. A cavity is provided in the friction lining for the passage of hydraulic fluid from the converter's hydraulic fluid circuit. The cavity, in a transition area to the friction surface of the friction lining includes a stamped region to create an edge-free transition.

Abstract: Hydrokinetic torque converter, including a housing driven by an internal combustion engine with a housing wall near the drive which is provided with a concentric guide hub, a pump wheel integrated into the housing wall away from the drive, a turbine wheel located between the pump wheel and the housing wall near the drive, which turbine wheel is non-rotationally connected by means of a turbine wheel hub to the output, possibly a stator located between the two, whereby the turbine wheel and/or the pump wheel are provided with axial bearings opposite the stator, and whereby the walls of the pump wheel and/or of the turbine wheel pressurized with axial pressure are provided on their radially inside diameter with mountings for fastening the axial bearings.

Abstract: In a hydrodynamic torque converter a pump wheel, a turbine wheel and a guide wheel are enclosed within a converter housing. These three wheels interact in a fluid cycle and are rotatable relative to one another. A controllable bridging clutch is located between the pump wheel and the turbine wheel and is disposed parallel to the torque transmission path between the two wheels. The clutch couples the turbine wheel to the pump wheel without any slippage and in dependence on the pressure of the hydraulic fluid in the converter housing. In the path of the bridging clutch, springs of a torsional vibration damper are arranged for dampening irregularities in the torque transmission on both the driving side and the driven side. A friction damper is connected in parallel with the torsional vibrational damper.
