Abstract
A hydrokinetic torque coupling device includes an impeller, a casing having a first engagement surface, a damper assembly, a turbine-piston and a drive-clutch component non-moveably attached to the turbine-piston and having a second engagement surface. The turbine-piston is axially displaceable relative to the casing to move the second engagement surface axially towards and away from the first engagement surface for positioning the hydrokinetic torque coupling device respectively into and out of a lockup mode in which the first and second engagement surfaces frictionally interlock with one another to mechanically lock the casing non-rotatably relative to the input part of the damper assembly. The drive-clutch component is configured to engage and rotationally drive a torsional vibration damper.
