FIELD: transport.
SUBSTANCE: invention relates to motor car production and can be used as an alternative for automatic gearboxes. Hydraulic transmission is composed of hydraulic and hydraulic pump and consists of housing (1) and rotors (12), (13) with plates (17), (18) engaged via gears (19) with counterweights (20). Distribution disc (23) has stator with shaped groove (24) provided with band brake (25) and disc shutters (26), (27). Besides, it has two suction chambers (29) and two pressure chambers (30) in the area of hydraulic pump. Pressure chambers (31) and displacement chambers (32) are arranged in the area of hydraulic motor. Openings are made on inner surface of stator (24) with spacing corresponding to hydraulic transmission shifting pitch while opening and closing of said of said openings are performed by generating line of distribution disc (23).
EFFECT: higher efficiency.
