Abstract
A driver disc has a series of pockets spaced along a circle about an axis of rotation thereof and inertia weights positioned and arranged to roll in the respective pockets. The driver disc is secured to the engine crankshaft for rotation therewith. A flywheel is secured to the driver disc for rotation therewith. A clutch has a friction pad assembly in engagement with the flywheel. The driver disc is resilient and possesses a first rigidity, within a plane normal to the axis of rotation, high enough to transmit torque between the engine crankshaft and the flywheel and a second rigidity, within a plane including said axis, which is lower than the first rigidity. With this system, transmission of heat generated due to frictional engagement between the flywheel and friction pad assembly to the pockets has been reduced.
