Abstract
A torsional vibration damper of a hydrokinetic torque-coupling device. The torsional vibration damper comprises a torque input member including first and second side plates axially spaced from and non-rotatably attached to one another, and a supporting member mounted therebetween, a unitary elastic member disposed between the first and second side plates and pivotable relative to and elastically coupled to the torque input member, and a resilient member disposed between the elastic member and the first side plate. The elastic member includes a core member rotatable relative the torque input member, and an elastic leaf integral with the core member and configured to elastically engage the supporting member. The elastic leaf has a proximal end non-moveably connected to the core member, a free distal end and a curved raceway portion disposed between the proximal and free distal ends of the at least one elastic leaf for bearing the supporting member.
