Abstract
A system for a flywheel assembly for use in conjunction with an internal combustion engine is disclosed. The flywheel assembly includes a flywheel in rotational association with a crankshaft of the internal combustion engine. The flywheel assembly further includes a cooling fan mounted over the flywheel, and capable of rotation therewith. The cooling fan and the flywheel are secured in a constant axial position relative to the crankshaft by virtue of a drive-cup and a retaining nut. Further, the flywheel includes a plurality of integrally formed, intersecting support ribs, for providing excellent dynamic stiffening (e.g., damping) capabilities to the flywheel assembly for substantially reducing and/or eliminating radiated noise.
