MOBILE ENERGY DEVICE

摘要

A mobile energy device includes an internal combustion engine, a drive wheels bridge and the hydromechanical transmission. The transmission includes a gearbox, a reversing adjustable hydraulic pump, which shaft is connected with a shaft of the internal combustion engine, a reversing hydraulic motor, which working cavities are connected with the working cavities of the reversing adjustable hydraulic pump by the supply lines, a reversing reduction gear, a frictional clutch, as well as a planetary adder, which sun and ring gears are kinematically connected with the shaft of the reversing hydraulic motor and the shaft of the internal combustion engine respectively, and a carrier is kinematically connected with the gearbox. The hydromechanical transmission is provided with a shift mechanism. The ring gear is kinematically connected with the shaft of the internal combustion engine through the reversing reduction gear and the frictional clutch. The sun gear is kinematically connected with the shaft of the reversing hydraulic motor through the shift mechanism mounted with the possibility of alternate connection of the shaft of the reversing hydraulic motor with the sun gear or with the sun gear and the carrier simultaneously. The shift mechanism can be made in the form of a controllable clutch.
