PCT No. PCT/GB97/00361 Sec. 371 Date Aug. 14, 1998 Sec. 102(e) Date Aug. 14, 1998 PCT Filed Feb. 10, 1997 PCT Pub. No. WO97/30298 PCT Pub. Date Aug. 21, 1997A twin flywheel (210) comprising first (211) and second (212) co-axially arranged flywheel masses which are mounted for limited angular rotation relative to each other. The flywheel masses (211, 212) are interconnected by at least one linkage arrangement (240), comprising a multi-link linkage (240) having two or more circumferentially spaced main links (242, 251) pivotally mounted on the second flywheel masses with the or each circumferentially adjacent pair of main links interconnect via a generally circumferentially extending connecting linkage, and an anchor link (242) which connects the multi-linkage (240) with the first flywheel mass. Relative rotation of the flywheel masses (211, 212) causes the multi-link linkage (240) to be pivoted relative to the second flywheel mass by the anchor link, so that when the twin mass flywheel is rotating, relative rotation of the flywheel masses (211, 212) is resisted by centripetal forces acting on the linkage arrangement. Any particular links may be in the form of a unitary link or in the form of a pair parallel plates. Associated with one or more links, or pivots or acting between the flywheel masses (211, 212) there may be controlling means to control the relative rotation of the flywheel masses (211, 212). |
