Abstract
A flywheel assembly having a clutch disk and at least one flywheel includes the use of at least one undulated ribbon spring formed of an elongated metallic strip, folded in accordion fashion, having an arcuate shape and having a plurality of flat-spring loop sections symmetrically staggered along the arcuate shape. The spring is disposed in a fluid filled chamber within the flywheel assembly. The spring is compressed and expands in response to relative rotary displacement between adjacent parts within the flywheel assembly. The spring absorbs vibration from the adjacent parts within the flywheel assembly. Further, the spring further inhibits the flow of fluid within the fluid filled chamber further absorbing vibrations in response to rotary displacement between adjacent parts within the flywheel assembly. The spring may be disposed in a fluid filled chamber formed within the clutch disk or in other portions of the flywheel assembly.
