FIELD: internal combustion engines.
SUBSTANCE: invention relates to cooling devices of power plants. Mobile working machine, in particular, dump truck or truck, comprises diesel-electric traction drive and cooling system. Said cooling system comprises radiator blower incorporating two radial fans and / or cooling injection fans each driven by hydraulic motor. At the same time diesel-electric traction drive is made with possibility of power generation only for power supply of traction drives of drive. Hydraulic motors are adapted to actuate by hydraulic energy provided by one or more hydraulic pumps driven through at least one dispensing box on an internal combustion engine and / or on a generator. At that, hydraulic motors of radiator fans and / or cooling injection fans are configured to set their speed variable regardless of internal combustion engine speed.
EFFECT: technical result consists in improvement of reliability of cooling system.
