FIELD: war material. SUBSTANCE: invention relates to transport engineering, particularly, to cooling systems of transport engines. According to invention, drive is furnished with hydraulic coupling installed in drive connecting reduction gear and fan through flexible coupling. Hydraulic coupling is mechanically coupled with fan through epicycle drive and carrier, and is hydraulically coupled with gear pump through hydraulic regulator which, in its turn, is coupled with temperature transmitter through comparator. Hydrostatic transmission is installed in parallel with hydraulic coupling. Pump of hydrostatic transmission is connected with input reduction gear, and motor, with fan through sun gear and carrier. Adjustable tilted plate of said pump is coupled with temperature transmitter through slave mechanism, amplifier and comparator. Proposed device provides automatic maintenance of preset temperature conditions in cooling system. EFFECT: improved reliability and reduced overall dimensions of power plant. 1 dwg
