Abstract
A torque-coupling device for coupling driving and driven shafts. The torque-coupling device comprises a casing having a locking surface, a torque converter, a locking piston having an engagement surface axially movable to and from the locking surface of the casing and a torsional vibration damper. The torsional vibration damper comprises a torque input member and a unitary radially elastic output member elastically coupled to the torque input member. The torque input member includes a radially oriented first retainer plate and at least one supporting member mounted thereto. The output member includes an output hub and an elastic leaf configured to elastically engage the supporting member upon rotation of the first retainer plate with respect to the output member. The output hub is configured for directly and non-rotatably engaging a driven shaft. The locking piston is non-rotatably connected to the torque input member of the torsional vibration damper.
