ABSTRACT:
A continuously variable transmission comprising a plurality of spokes extending radially from a spoke shaft upon which the spokes are mounted for circular movement about the spoke shaft. A driven ring is positioned relative to the spoke shaft to be engaged by one end of each spoke each time a spoke aligns with a selected direction from the spoke shaft so that movement of the spokes about the spoke shaft will rotate the driven ring by consecutive engagement of the spokes with the driven ring. The spokes are moved circularly about the spoke shaft by a rotating driving ring that extends about the spoke shaft and has a plurality of equally spaced apertures formed radially therethrough to pass the spokes through the driving ring. The driving ring is supported for sliding movement parallel to the selected direction of extension of the spokes for which the spokes engage the driven ring to vary the gear ratio of the transmission.
