The author has suggested the structure scheme of hydrostatic-mechanical transmission with hydrostatic steering system, which includes a hydraulic pump, a hydraulic motor and a hydraulic clutch. The hydraulic clutch allows the third additional power flow inclusion. An analysis is conducted regarding the influence of additional power flow on the processes that characterize the work condition of hydraulic machines and the transmission in general and its efficient use in tracked vehicles. The results of simulation allows to conclude that including the additional flow to the steering system is advisable, it leads to torque reducing on hydraulic motor shaft and it gives the expected pressure reduction in mainline.
