Abstract
A hydrodynamic torque converter wherein the housing is connected to the output element of an engine in the power train of a motor vehicle and receives a coaxial hub which is rotatable by the turbine wheel in the housing or by a clutch disk forming part of a lockup clutch and being axially movably but non-rotatably mounted on the hub. The lockup clutch further comprises a piston which is rotatably and axially movably mounted on the hub, and a laimina which is non-rotatably but axially movably mounted in the housing and extends radially inwardly between the piston and the clutch disk. The clutch is engaged when the piston is moved axially of the housing to thus urge the lamina against the clutch disk and to thus bias the clutch disk against an adjacent wall of the housing so that the clutch disc then transmits torque between the housing and the hub to thus bypass the torque transmitting connection between the housing and the hub by way of a satator wheel in the housing and the turbine wheel.
