Abstract
A torque converter is provided that includes an impeller having an impeller shell with a first surface, an axially displaceable turbine-piston hydrodynamically drivable by the impeller and including a turbine-piston shell and a turbine-piston flange with a second surface, and a clutch plate interposed between and axially displaceable relative to at least one of the first and second surfaces. The turbine-piston is axially movable relative to the impeller to move the second surface of the turbine-piston flange towards and away from the first surface for positioning the torque converter into and out of a lockup mode in which the first and second surfaces and the clutch plate surfaces frictionally interlock with one another so that the impeller is mechanically locked to and non-rotatable relative to the turbine-piston.
