Abstract
A hydrokinetic torque-coupling device for a hybrid electric vehicle, comprising a casing rotatable about a rotational axis, a torque converter including an impeller wheel and a turbine wheel, a lockup clutch including a dual piston assembly, and a selective clutch disposed outside of the casing. The selective clutch includes an input member and an output member non-rotatably mounted to the casing. The dual piston assembly includes a main piston and at least one secondary piston mounted to the main piston and axially moveable relative thereto. The main piston is selectively axially moveable relative to the casing and the at least one secondary piston between a lockup position and a non-lockup position. The output member is selectively axially moveable relative to the input member between an engaged position and a disengaged position. The output member selectively is axially moveable by action of the at least one secondary piston.
