Abstract:
A twin mass flywheel comprising a first flywheel mass in connection with an engine and including a first track which extends generally circumferentially part way around the first flywheel mass and a second flywheel mass in connection with a transmission and including a second track extending at an angle relative to the first track, the masses being rotatable relative to each other about an axis through a limited angle and this relative rotation being controlled by connection means which engages with and moves along the first and second tracks and whose center of gravity moves radially with respect to the axis as the first and second flywheel masses rotate relative to each other, the centripetal loads acting on the connection means as the twin mass flywheel rotates tending to reverse said relative rotation of the masses to restore the masses towards a predetermined relative rotational zone thus damping torsional vibrations between the engine and transmission.
