Hydrokinetic torque coupling device with centered friction disc

A hydrokinetic torque-coupling device for coupling a driving shaft and a driven shaft together, comprising:

• a casing rotatable about a rotational axis and having a locking surface;
• an impeller wheel coaxially aligned with the rotational axis and comprising an impeller shell and impeller blades fixedly attached to the impeller shell;
• a turbine wheel coaxially aligned with and hydrodynamically drivable by the impeller wheel, the turbine wheel comprising a turbine shell and turbine blades fixedly attached to the turbine shell;
• a lockup piston axially movable toward and away from the locking surface of the casing to position the hydrokinetic torque coupling device into and out of a lockup mode;
• a friction disc axially moveable along the rotational axis to and from the locking surface of the casing, the friction disc including a generally radially orientated friction ring disposed axially between the lockup piston and the locking surface of the casing, and at least one driving tab;
• and
• a torsional vibration damper comprising an input member in the form of the friction disc, a plurality of circumferentially acting first torque transmitting elastic members and an engagement member elastically coupled to the friction disc through the first torque transmitting elastic members;
• the friction ring of the friction disc having a radially outer peripheral surface defining a centering surface of the friction disc;
• wherein the engagement member includes at least one centering tab extending toward the friction ring of the friction disc and having a centering surface disposed adjacent to and facing the centering surface of the friction disc to center the friction disc with respect to the engagement member of the torsional vibration damper.
