Patent ID: 10352423

Abstract:
A hydrokinetic torque-coupling device for coupling driving and driven shafts. The torque-coupling device includes a casing having a locking surface, an impeller wheel and a turbine wheel hydrodynamically drivable by the impeller wheel, a lockup piston axially movable toward and away from the locking surface, a friction disc including a generally radially orientated friction ring and at least one driving tab, and a torsional vibration damper comprising the friction disc, elastic members and an engagement member elastically coupled to the friction disc through the elastic members. The friction ring has a radially outer peripheral surface defining a centering surface of the friction disc. The engagement member includes at least one centering tab extending toward the friction ring 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.
