ABSTRACT:
A hydraulic and gear transmission includes a body having journaled therein axially aligned input and output shafts each having inner ends journaled relative one another. A carrier mounted on the output shaft supports a plurality of planet gears in engagement with a sun gear mounted on the input shaft inner end. Input motion as directed through the sun and planet gears, reacts with an outer most ring gear engaging the planet gears while the movement of this ring gear is controlled by the application of or absence of torque as applied to a variator gear also engaging the ring gear. Torque to the variator gear is regulated by a turbine gear attached thereto and which is activated by a pump gear driven by the input shaft.
