Continuously variable transmission

A continuously variable transmission, comprising:

• a case;
• a driven ring mounted on the case for rotation about a driven ring axis coinciding with the circular axis of the driven ring;
• a spoke shaft mounted on the case to pass through a central portion of the driven ring:
• a plurality of spokes pivotally mounted on the spoke shaft and extending radially therefrom for circular movement about the spoke shaft, wherein the spoke shaft is positioned with respect to the driven ring axis such that the radially extensive end of each spoke will engage the driven ring at such times that the spoke extends in a selected direction from the spoke shaft;
• a driving ring supported in the case to extend about the spoke shaft, the driving ring having a plurality of equally spaced apertures formed radially therethrough for passage of the spokes through the driving ring;
• a driving ring support whereon the driving ring is rotatably supported for rotational movement about the spoke shaft, wherein the driving ring support is slidably mounted on the case for movement thereon along a line paralleling said selected direction from the spoke shaft;
• an input shaft mounted on the driving ring support and mechanically coupled to the driving ring for rotating the driving ring about the spoke shaft on the driving ring support;
• and
• an output shaft mounted on the case and mechanically coupled to the driven ring for rotation of the output shaft by the driven ring.
