Abstract
An actuation force generating arrangement for a centrifugal clutch includes a housing, a supporting element, and a plurality of centrifugal members. The housing is rotatable about an axis, the housing having a plurality of first supporting areas which each extend radially with respect to the axis. The supporting element is axially movable with respect to the housing and has 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. Each of the first and second support areas has a first portion and a second portion which lies radially outside of the first portion, the first and second support areas being inclined with respect to each other at a relative inclination angle which is greater at the second portions than at the first portions. The centrifugal members are supported between respective pairs of first and second support areas, each centrifugal member being radially displaceable by centrifugal force along a respective pair of support areas.
