Patent ID: 8747268

Claim:
A continuously variable transmission system comprising: a gear set comprising one or more sun gears, one or more planetary gears, and a planetary gear carrier arm on which the one or more planetary gears are mounted for rotational movement, the one or more sun gears and the one or more planetary gears are mounted for rotational engagement and movement with respect to each other, at least one of the one or more sun gears and the planetary gear carrier arm couples to an input shaft and a portion of the gear set couples to an output shaft directly coupled to a load to receive feedback, wherein the gear set further comprises a ring gear, the ring gear and the one or more planetary gears are mounted for rotational engagement and movement with respect to each other, the at least one of the one or more sun gears couples to the input shaft and the ring gear couples to the output shaft; a rotary coupling unit having an input rotationally coupled to the at least one of the one or more sun gears and the planetary gear carrier arm and an output that directly couples to the output shaft; and a feedback unit having one or more feedback gears that rotationally couples the output shaft back to the ring gear.
