An automatic transmission is described incorporating a means for varying the ratio of input rotational velocity to output rotational velocity. An open ended cylinder cam (30) is mounted on a cam driver (25) having a helical gear tooth thereon engaging corresponding helical internal gear teeth within the cylinder cam. The cylinder cam (30) incroporates a continuously varying cam angle and is axially translatable along the cam driver (25); the cam (30) is positioned on the cam driver (25) automatically in accordance with torque requirements by the forces transmitted to the cam through the helical gears of the cam driver (25). Spherical cam followers (40) mounted in a sphere cluster (42) engage the cylinder cam (30); the clusters are mounted for rotation about an axis perpendicular to the axis of rotation of the cam. |
