ABSTRACT:
A viscous resistance generation mechanism includes a first flywheel, a plurality of sliders and a driven plate. The first flywheel includes an arcuate fluid filled chamber, with the plurality of sliders disposed within the fluid filling chamber and movable in the circumferential direction. The driven plate is formed with a plurality of protrusion which are inserted into each of the plurality of sliders. The plurality of sliders are connected to the driven plate, and the interior of each of said sliders is sealed from the fluid filled chamber. Small torsional vibrations are dampened by large gaps between the fluid filled chamber and the plurality of sliders, and large torsional vibrations are dampened by small gaps between the plurality of protrusions and the interior of each of the plurality of sliders.
