A centrifugal clutch for coupling a drive shaft to a driven member at rotary speeds above a predetermined threshold, comprising: a centrifugal slider ( 302 ) with a massive enlargement ( 320 ) at one end and a first coupling formation; a frame ( 301 ) formed to carry the centrifugal slider on formations to constrain it to sliding motion between an extended radial position and a retracted radial position, and to fit fixedly on the drive shaft to be driven by it, with the shaft at right-angles to the axis of sliding motion of the frame, whereby the frame ( 301 ) and the slider ( 302 ) cooperate to constitute a flywheel ( 3 ) on the drive shaft axis and the centre of inertia of the centrifugal clutch is axial only when the centrifugal slider is at its extended radial position, whereby its rotation is fully balanced when the clutch is engaged. |
