Torsionally compliant and damped sprocket system with position stops

摘要

The present invention relates to a torsionally compliant sprocket system which absorbs crankshaft torsional vibrations and minimizes their transfer to other components in the engine system. In particular, the present system interposes resilient spring members between a crankshaft sprocket and an adjacent balance shaft drive sprocket which are interconnected. A damping mechanism provides damping of the system to reduce resonant oscillations.
