Continuously variable-ratio transmission

A continuously variable transmission, comprising:

• an input pulley having a first subassembly supported upon a first rotatably driven shaft;
• an output pulley having a second subassembly supported upon a second rotatable shaft;
• a closed loop belt supported about said input and output pulleys;
• said input and output pulley subassemblies each further including pluralities of left and right link elements pivotally supported and extending from each of a plurality of pulley segments to each of axially spaced apart first and second shaft supported rotating elements for positioning said pulley segments in an outwardly circumferentially arrayed fashion about each of said first and second shafts
• axial displacement of a first pair of said shaft supporting elements of said input pulley subassembly varying a collective diameter formed by said arrangement of segmented pulley segments configured upon said input pulley subassembly;
• and
• concurrent axial displacement of a second pair of said shaft supporting elements in said output pulley subassembly inversely varying with said displacement of said first pair of shaft supporting elements for reciprocally varying a collective diameter formed by said arrangement of said pulley segments configured upon said output pulley subassembly, and in order to maintain a constant circumference of said belt supported about said segmented pulley segments for each of said input and output pulleys.
