| description | A continuously variable transmission in which a chain is capable of changing width in order to be accommodated on fixed conical pulley surfaces at desired varying radii on the pulleys, commensurate with desired gear ratio. The chain is comprised of individual links whose widths can be varied and locked at different widths. The links are locked into position when the chain is bent in one direction and become unlocked when the chain is bent in the other direction. Idle gears are provided to introduce the chain to the pulleys tangential to arcs about the pulley and at desired radius from the pulley center. The idler gears bend the chain in appropriate directions to unlock or lock the chain links at desired widths depending upon the location where the links engage the pulleys. |
