Abstract:
A twin mass flywheel comprising:first and second co-axially arranged flywheel masses which are mounted for limited angular rotation relative to each other, the flywheel masses being interconnected by at least one linkage arragement, each linkage arangement having two or more circumferentially spaced main links pivotally mounted on one of the flywheel masses with each circumferentially adjacent pair of main links being interconnected via a generally circumferentially extending connecting linkage thereby forming a multi-link linkage, and an anchor link which pivotally connects the multi-link linkage with the other flywheel mass, relative rotation of the flywheel masses causing the multi-link linkage to be pivoted relative to said one flywheel mass by the anchor link, so that when the twin mass flywheel is rotating, relative rotation of the flywheel masses is resisted by centripetal forces acting to return the linkage arrangement to its centrifugally neutral position.
