Abstract
A composite flywheel wherein a primary mass is rotatable by the engine of a motor vehicle and can transmit torque to a secondary mass--which serves to rotate the clutch plate of a friction clutch--by way of several sets of coil springs and a planetary transmission. A friction clutch serves to oppose certain angular movements of the primary and secondary masses relative to each other, and a slip clutch is provided to limit the magnitude of the torque which can be transmitted by the planetary transmission.
