Gear-based continuously variable transmission systems and methods thereof

摘要

A continuously variable transmission system and a method of making a continuously variable transmission system is described. The present invention includes a gear set having at least a sun gear, 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 sun gear and the one or more planetary gears are mounted for rotational engagement and movement with respect to each other, and one of the sun gears and the planetary gear carrier arm couples to an input shaft and another portion of the gear set couples to an output shaft to receive feedback. A rotary coupling unit having an input rotationally coupled to at least one of the one of the sun gears and the planetary gear carrier arm and an output that rotationally couples to the output shaft is also provided.

1. A continuously variable transmission system comprising:
a gear set comprising one or more sun gears, one or more planetary gears, a ring gear, 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, the ring gear 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 providing a first input to the one or more planetary gears and the ring gear directly couples to an output shaft directly coupled to a load to receive feedback; and 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 rotationally couples to the output shaft, where a portion of rotational energy of the output shaft is transferred as a second input to the one or more planetary gears at the ring gear.
