ABSTRACT:
A relatively inexpensive simplified type of split-torque power transmission. A simple planetary gear assembly is employed having a carrier connected to the input with a set of planet gears, a ring gear, and a sun gear. Suitable speed-varying means are used, such as two variable-stroke hydraulic units, each having rotary shafts and driving relation therewith, the two units being hydraulically connected together so that one serves as a pump while the other serves as a motor, and vice versa. Two gear trains respectively connect the ring gear to the first rotary shaft and the sun gear to the second rotary shaft. A first clutch means connects the first rotary shaft in driving relation to the output means, and a second clutch means connects the second rotary shaft in driving relation to the output shaft. A three-range transmission and a four-range transmission are also shown.
