Abstract
A centrifugal clutch mechanism according to the present invention includes a pair of spaced clutch shoes, one being a power shoe and the other being an energizing shoe, that are movably supported by a rotor element that is rotated by a drive source. A clutch housing having an internal cylindrical surface for mating engagement with the clutch shoes is connected to a rotatable driven element and is rotatable along with the rotor element responsive to forces transferred to the clutch housing from the clutch shoes. Clutch energization or expansion is induced by a centrifugally movable modulating arm having a cam roller that has operative engagement with a cam surface provided on the energizing shoe. Centrifugally induced movement of the modulating arm is controlled by a slippage control spring and by an anti-self-energizing spring. A drive block supported by the rotor element transfers forces to the power shoe in a predetermined vectored relationship which may be modified by the angular relationship of the drive block engagement with the drive shoe.
