Patent ID: 10495197

Abstract:
A continuously variable transmission ring driving mechanism, including a cylinder having a ring-shaped recess with a ring-shaped bottom-wall and two ring-shaped sidewalls, the ring-shaped bottom-wall having axial guide-holes each for receiving a continuously variable transmission rod; rollers pivotally disposed at the ring-shaped bottom-wall and the ring-shaped sidewalls and exposed partially from the ring-shaped recess; and a continuously variable transmission annular unit movably received in the ring-shaped recess, wherein an inner ring-shaped surface of the continuously variable transmission annular unit is in contact with the rollers of the ring-shaped bottom-wall, and two opposing ring-shaped surfaces of the continuously variable transmission annular unit are in contact with the rollers of the ring-shaped sidewalls, the continuously variable transmission annular unit having oblique guide-holes, allowing the oblique guide-holes to guide the continuously variable transmission rod along axial direction of the cylinder when the continuously variable transmission annular unit rotates about the cylinder.
