HYDROMECHANICAL TRANSMISSION Russian patent published in 2021 - IPC F16H41/00 F16H47/06 

FIELD: transport machinery.

SUBSTANCE: invention relates to automotive industry. Hydromechanical transmission comprises inlet and outlet shafts installed in housing, double-turbine hydraulic transformer having centrifugal pump impeller connected in series in working fluid circulation circle, connected to input shaft, first turbine wheel of axial type, second turbine wheel of centripetal type, reactor, two mechanical transmissions with transmission ratios of one sign, connected to turbine wheels, two controlled coupling clutches connecting mechanical transmissions with output shaft. Transmission is additionally equipped with the third mechanical transmission and the third controlled coupling, at that the third mechanical transmission is made with the transfer relation of the opposite sign and is connected to the output shaft by means of the third controlled coupling clutch.

EFFECT: enabling expansion of operational capabilities of hydromechanical transmission.
