ABSTRACT:
A centrifugal coupling with fly elements pressable against the internal surface of a friction drum contact to spring biasing forces wherein the fly elements each include at least two concentric partial weights mutually connected by radially-acting compression springs. The radial stroke of the inner partial weight or weights is limited by a primary side stop, so that from a specific predetermined speed any further increase in the centrifugal force from the inner partial weight directly acting upon the outer partial weight is prevented. The partial weights are further provided with check ramps, inclined in the circumferential direction, for a driver pin mounted on the primary side in order to give the torque curve of the coupling an optimum configuration. In some embodiments the check ramp on the outer partial weight may be replaced by a lever mounted on the primary side which transforms the force generated by the inner partial weight into a centripetal force acting upon the outer partial weight.
