FIELD: mechanical engineering.
SUBSTANCE: invention relates to the field of mechanical engineering, in particular to vehicle drives. The drive contains an engine, a wheel speed control system, a positive displacement hydraulic system. The hydraulic system has a pump unit driven by an engine by means of a pump unit reducer, the working fluid from which is supplied to the hydraulic motor. The hydraulic motor has a fixed displacement. The pumping unit is made in the form of several hydraulic pumps. The reducer of the pumping unit is made as a distributor. The wheel speed control system has the ability to provide a supply of working fluid to the hydraulic motor from any one of the hydraulic pumps and from several hydraulic pumps by connecting them to the hydraulic system in parallel. The wheel speed control system has a mechanical gearbox for changing the speeds, the input shaft of which is driven by a hydraulic motor, and the output shaft is the drive of the transfer case for wheel rotation.
EFFECT: simplification of the design is achieved.
