Abstract

Each cheek web has a small bar opposite an interstice of the other. The risk of unwedging of the bars from the interstices is eliminated by the extension of four bars in the axial direction. The small width and the high efficiency ratios of the variators enables it to be fixed directly on the pedal and gear mechanism of a cycle.

The inclination of the flanges cannot be less than 150 by comparison with the vertical (for the rise of the belt) gives an angle of 30 to the convergence of the flanges. This constant constant angle
