Abstract

A variety of transmission mechanisms are provided that include split pulleys nested within each other in order to reduce the size of the transmissions, to provide infinitely variable transmission ratios that include forward and reverse ratios, or to provide some other benefits. These transmissions include "W"-shaped belts, having both contact surfaces that are directed outward from the belt and inward, toward a center-line of the belt, to contact the pulleys with respective different inward- and outward-directed contact surfaces. Accordingly, the surfaces at which the belt contacts the different pulleys may be substantially the same with respect to a hinge or other structure of the belt. This improvement may permit higher levels of power transmission, increased efficiency, and increased transmission lifetime. Additionally, variable-eccentricity variable transmissions are provided wherein the eccentricity of rotation of an inner, nested pulley varies with changes in the transmission ratio of the transmission.
