Abstract

See full text

A continuously variable transmission features an inner ring and an outer ring. Each of the inner ring and the outer ring is split into a first portion and a second portion. At least two balls are positioned between the inner ring and the outer ring. The at least two balls also are positioned between the first and second portions of the inner and outer ring. The at least two balls rotate with rotation of the input shaft. As the distance between the first and second portions of the outer ring changes, the at least two balls move to a smaller radius of travel or a larger radius of travel. The rotation of the balls is transmitted to an output shaft. The input shaft and the output shaft are directly connectable through a one-way clutch to allow engine braking and/or push starting of the associated engine. A dedicated lubrication system also can be provided.
