Abstract

A clutch can include an input; an output; a centrifugal clutch mechanism that transfers energy from the input to the output, the centrifugal clutch mechanism including: a disk; centrifugal weights movably coupled to the disk; and a central shaft rotatable relative to the disk and extending through the disk, the central shaft comprising drive surfaces, wherein the disk is rotatably coupled to the input, wherein the output is rotatably coupled to the central shaft, wherein the centrifugal weights rotate between a disengaged position in which the centrifugal weights do not interface with drive surfaces and an engaged position in which the centrifugal weights interface with the drive surfaces, and wherein the centrifugal weights are disposed inside the perimeter of the disk when the centrifugal weights are in the engaged position.
