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 selectable one-way clutch disposed outside of the casing. The selectable one-way clutch includes an outer race, torque transmitting elements, an inner race drivingly and non-rotatably connectable to the outer race through the torque transmitting elements, and a plurality of actuator members configured to circumferentially displace one of the torque transmitting elements in each pair of the torque transmitting elements. The dual piston assembly includes a main piston and at least one secondary piston having actuator rods. One torque transmitting element of each pair of the torque transmitting elements is moveable by axial movement of the actuator rods of the at least one second lockup piston acting to the actuator members.
