Abstract
A hydrokinetic torque coupling device comprises a casing rotatable about a rotation axis, a torque converter including an impeller wheel and a turbine wheel disposed in the casing coaxially with the rotation axis, a locking piston including an annular piston body and a plurality of drive teeth unitary with the piston body, and a torsional vibration damper comprising a input member non-rotatably coupled to the drive teeth of the locking piston, elastic members and an output member elastically coupled to the input member trough the elastic members. The locking piston is axially moveable so as to selectively engage the locking piston against the casing. The input member has window-shaped mating openings complementary to each of the drive teeth. The drive teeth drivingly engage the mating openings of the input member so as to non-rotatably couple the locking piston and the input member.
