ABSTRACT:
A centrifugal clutch includes a housing which is rotatable about an axis, the housing having a plurality of first supporting areas which each extend radially with respect to the axis; a pressing plate which is axially movable with respect to the housing and is coupled to the housing for rotation about the axis; and a supporting element which is axially movable with respect to the housing, the supporting element having a plurality of second supporting areas which each extend radially with respect to the axis, each second support area being separated from a respective first support area by an axial distance which decreases with radial distance from the axis. A plurality of centrifugal members are supported between respective pairs of first and second support areas, each the centrifugal member being radially displaceable by centrifugal force along the respective pair of support areas to exert force along a force transmission path between the supporting element and the pressing plate. An energy accumulator arrangement acts between the supporting element and the pressing plate to load the pressing plate away from the supporting element in a clutch engaging direction, and a clutch release arrangement provides a releasing force in opposition to the load of the energy accumulator arrangement.
