FIELD: machine building.
SUBSTANCE: differential hydro-mechanical drive consists of two hydro-motors (10, 11) not interconnected hydraulically, of input shafts (2, 3) for connection with hydraulic motors, and of output shaft (4) for connection with propeller of vehicle. A differential reducer is duplex, has common unit (9) of satellites and transfers torque to the output shaft. Due to step-less change of ratio of angular rate of input shafts of hydro-motors there occurs step-less change of angular rate of output shaft of the drive up to its complete stop and smooth reverse from it.
EFFECT: wide range of change of rotation rate of output shaft.
