FIELD: machine building.
SUBSTANCE: invention relates to a hydraulic system for controlling cooling and lubrication of an automatic gearbox with a dual clutch of a vehicle. Hydraulic system comprises a clutch lubricant control valve, the outlet end of which is connected to the oil supply circuit for clutch lubrication, a gear lubrication control valve, the outlet end of which is connected to the oil supply circuit for lubrication of the clutch of the gear and bearings, and inlet end, at first common end, is connected in parallel to inlet lug of clutch lubricant control valve. System additionally comprises a mechanical pump and an electronic pump, the inlet ends of which are connected to an oil storage tank, respectively. Outlet end of the mechanical pump and the outlet end of the electronic pump are connected in parallel at the second common end. Cooler is arranged between first common end and second common end.
EFFECT: higher reliability of lubricated elements of gearbox.
