Abstract
An improved differential drive mechanism includes a clutch assembly which is engaged to retard relative rotation between driving and driven members. A clutch actuator assembly includes a pair of flyweights which are rotated at a speed which varies as a function of variations in the speed of relative rotation between the driving and driven members. The flyweights are hinged to move outwardly under the influence of centrifugal force as they are rotated. To prevent excessive loading on hinge connection at high rotational speeds, outward movement of the flyweights is limited by a pair of stop members which engage outer surfaces of the flyweights. The flyweights are pivotally mounted on the stop members and the torque for rotating the flyweights is transmitted from an input shaft to the flyweights through the stop members. To prevent overloading of a flyweight drive mechanism, secondary clutches are provided between the stop members and input shaft.
