Abstract
A drive system includes a planetary gear system includes a sun gear secured to an input shaft. One or more planetary gears rotatably mounted to a cage engage the sun gear. The planetary gears likewise engage a ring gear encircling the planetary and sun gears. A coupler is selectively engageable between an output shaft of the planetary gear system and either the cage or the ring gear. A brake is movable between engagement with whichever of the cage and ring gear to which the coupler is not engaged. In some embodiments the coupler rotatably mounts to a brake embodied as a cylindrical slider such that the coupler is restrained from moving along an axis of rotation of the coupler. A detent mechanism engages the coupler and brake to retain them in positions corresponding to forward and reverse.
