An automatic transmission incorporating a means for varying the ratio of input rotational velocity to output rotational velocity. A cylinder cam is mounted on a cam driver having a helical gear tooth thereon engaging corresponding helical internal gear teeth within the cylinder cam. The cylinder cam incorporates a continuously varying cam angle and is axially translatable along the cam driver; the cam is positioned on the cam driver automatically in accordance with torque requirements by the forces transmitted to the cam through the helical gears of the cam driver. Spherical cam followers mounted in a sphere cluster engage the cylinder cam; the clusters are mounted for rotation about an axis perpendicular to the axis of rotation of the cam. |
