An exemplary configuration of the oil control system of the hybrid transmission described in the present embodiment is shown in fig. 1 based on the overall description above. The oil tank 1 is internally provided with the suction filter 2 for filtering oil, and the oil filtered by the suction filter 2 in the oil tank 1 can flow into the main oil way 6 and the cooling and lubricating oil way 10, so that the cleanliness of the oil in the flowing process is improved. To highlight the arrangement of the suction filter 2 inside the tank 1, only the structure of the oil pan in the tank 1 is shown in fig. 1.
In this embodiment, the main oil passage 6 is provided with an electronic pump 3 for driving the oil in the oil tank 1 to flow into the main oil passage 6, and the cooling and lubricating oil passage 10 is provided with a mechanical pump 4 for driving the oil in the oil tank 1 to flow into the cooling and lubricating oil passage 10. The main oil pressure is supplied by the electronic pump 3, and the rotating speed of the electronic pump is not limited by the speed of the vehicle and the rotating speed of the engine, so that the pressure regulating range of the main oil pressure is large, meanwhile, the rotating speed of the electronic pump 3 is changed according to the requirement on the main oil pressure, and the oil liquid regulating efficiency is improved.
