HYDROKINETIC TORQUE COUPLING DEVICE WITH TURBINE MADE OF LIGHTWEIGHT MATERIAL AND TORSIONAL VIBRATION DAMPER

A hydrokinetic torque-coupling device comprises an impeller wheel, a turbine wheel drivable by the impeller wheel, a torsional vibration damper, and a turbine hub non-rotatably connected to the turbine wheel. The turbine wheel includes a turbine shell and at least one coupling pin formed integrally with the turbine shell and extending radially outwardly from the turbine shell. The torsional vibration damper comprises a first damper, a driven member rotatable relative to the first damper retainer, and damper elastic members interposed between the first damper retainer and the driven member. The turbine hub is non-rotatably coupled to the driven member of the torsional vibration damper. The first damper retainer has at least one angularly extending bayonet slot configured to receive the at least one coupling pin therein such that the at least one coupling pin being angularly moveable in the at least one bayonet slot relative to the first damper retainer.
