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.

Lock-up clutch and torsional vibration damper for hydrokinetic torque coupling device, and related methods

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 turbine hub disposed in the casing coaxially with the rotation axis and fixed to the turbine wheel, and a torsional vibration damper. The torsional vibration damper comprises a driven member fixed to the turbine hub, a back plate rotatably mounted to the turbine hub, a plurality of circumferentially acting elastic members, and a damper retainer plate rotatably mounted to the back plate coaxially with the rotation axis. The back plate has a plurality of window-shaped openings separated circumferentially from one another by radial tabs. The elastic members are interposed between the driven member and the back plate in the window-shaped openings. The damper retainer plate is operatively connected to the elastic members.

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 turbine hub disposed in the casing coaxially with the rotation axis and fixed to the turbine wheel, and a torsional vibration damper. The torsional vibration damper comprises a driven member fixed to the turbine hub, a drive member rotatable relative to the driven member about the rotation axis, and a plurality of circumferentially acting outer and inner elastic damping members. The drive member and the driven member are operatively connected to both the radially outer and inner elastic damping members. The radially outer and inner elastic damping members are arranged in series.
