ABSTRACT:
The two-stage torsional vibration damper includes an outer hub driven by a orque input drive member, a ring member, rotatably supported in the outer hub, an inner hub rotatably supported in the ring member, and a torque output member at the center of the inner hub. A front spring retainer plate is attached to one side of the ring member and a rear spring retainer plate is attached to the other side of the ring member. The spring retainer plate retains outer spring assemblies in spring assembly apertures in the outer hub and retain inner spring assemblies in spring assembly apertures in the inner hub. Torque is transmitted from the outer hub to the outer spring assemblies to the spring retainer plates to the inner spring assemblies to the inner hub. The outer spring assemblies can be compressed until rotation of the inner hub relative to the ring member is stopped. Increases in torque after rotation between the outer hub, the ring member and the inner hub is stopped, is transferred from the outer hub, to the ring member and to the inner hub. The ring member can be an integral part of the front and rear spring retainer plates rather than a separate piece, if desired.
