HYDROMECHANICAL TRANSMISSION Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: hydromechanical transmission has input and output shafts and two hydraulically interconnected controlled hydraulic motors. The four-link planet mechanism has carrier with the satellites, two central wheels provided with outer teeth, central wheel provided with inner teeth, controlled clutches, and gear transmissions. The first hydraulic motor is kinematically connected with the first central wheel through a gearing. The second hydraulic motor is connected with the central wheel through the first gearing and controlled clutch. The planet mechanism has coupled satellites. The second hydraulic motor is connected with the second central wheel via the gearing and controlled clutch. The input shaft is connected with the carrier of the planet mechanism. The output shaft is kinematically connected with the central wheel.

EFFECT: enhanced efficiency.
