Abstract
A hydrokinetic torque converter includes an impeller, an axially displaceable turbine piston, and impeller and turbine-piston lockup clutch core plates. The impeller lockup clutch core plate is situated between the impeller shell and the turbine-piston shell, is connected to an impeller core ring, and has a first surface. The turbine-piston lockup clutch core plate is situated between the impeller shell and the turbine-piston shell, is connected to a turbine-piston core ring, and is axially displaceable with the turbine-piston to move a second surface of the turbine-piston lockup clutch core plate axially towards and away from the first surface for positioning the torque converter respectively into and out of a lockup mode in which the turbine-piston is mechanically interlocked to the impeller.
