Abstract
Torsional vibration dampers (TVDs) having a plurality of spokes that are asymmetric by having a changing spoke thickness in the angular direction with the greatest thickness at the position where the belt torque and the dynamic torque of the TVD act in unison are disclosed. The spokes, which connect a central member to a peripheral rim, include an asymmetrical thickness in an angular direction, as evidenced by a cross-section view transverse to a radial length of each of the plurality of spokes. Engine systems having one of the disclosed TVDs mounted to a shaft are also disclosed, for example a TVD mounted to a crankshaft.
