Abstract:
A twin mass flywheel (10) comprising two co-axially arranged flywheel masses (11,12) which are mounted for limited angular rotation relative to each other; and a plurality of pivotal linkages (40) interconnecting the two flywheel masses, each linkage comprising a first link (41) pivotally connected via a first pivot (43) to one (12) of the flywheel masses, a second link (42) pivotally connected via a second pivot (44) to the other (11) of the flywheel masses, and a third pivot (45) for pivotally connecting the first and second links, each pivotal linkage being capable of adopting a geometrically neutral position in which the third pivot (45) and the first or second pivot (43,44) can become aligned on a radial plane of the twin mass flywheel (10); and a resilient means (46) which encircles the first or second pivot for controlling the relative rotation of said flywheel masses (11,12).
