Abstract:
A device comprising:two opposing cones, one a drive shaft and the other a driven shaft, said cones having axes in a common plane, said cones intersecting said common plane on two parallel lines,a power transfer element chosen from the group consisting of substantially rigid rings and substantially flexible belts, said power transfer element encompassing one of two said cones, said power transfer element being approximately as thick as the distance between said parallel lines and said power transfer element being nipped between said cones,a controlling mechanism for applying lateral pressure on said power transfer element, said controlling mechanism moving back and forth on a line substantially parallel to said parallel lines, said controlling mechanism making contact with said power transfer element at a distance from said common plane no greater than the greatest distance from said common plane to either of said cones, said controlling mechanism making contact with said power transfer element via wheels, said wheels traveling in a plane substantially tangential to said power transfer element,whereby such device constitutes a continuously variable transmission.
