Problems solved by technology
During the coupling process of the dual clutch in the wet dual clutch automatic transmission, due to the large amount of heat generated by sliding friction, the dual clutch needs to be cooled and lubricated by cooling oil, otherwise the dual clutch will be ablated, but the existing wet dual clutch transmission It is only aimed at traditional internal combustion engines, and does not involve the combination of electric power and internal combustion engines, making the cooling and lubrication of existing wet dual-clutch automatic transmissions unsuitable for dual-clutch hybrid vehicles. Therefore, there is an urgent need for a hydraulic control system to Dual-clutch automatic transmission for dual-clutch hybrid electric vehicles for effective cooling lubrication and control

The invention provides a hydraulic control system of a double-clutch automatic transmission, the transmission and a vehicle. A main control oil way of the hydraulic control system is connected with adouble-clutch cooling oil way and a clutch control oil way , the double-clutch cooling oil way is connected with a first clutch and a second clutch, a single-clutch cooling oil way is connected withthe double-clutch cooling oil way, an electric motor is connected with an electric motor clutch, the clutch control oil way is connected with the first clutch, the second clutch and the motor clutch,the first clutch and the second clutch can be cooled and lubricated through the double-clutch cooling oil way, cooling and lubricating the electric motor and the electric motor clutch through the single clutch cooling oil way, controlling all the clutches through a clutch control oil way, the problem that an existing hydraulic system cannot be suitable for lubricating cooling and control of a double-clutch hybrid power vehicle is solved, so that the hydraulic control system can be used for a hybrid power system with the double-clutch automatic transmission and an electro-hydraulic parking system.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a hydraulic control system of a dual-clutch automatic transmission, a transmission and a vehicle. Background technique [0002] With the development of the economy and the improvement of people's living standards, automobiles have become the main means of transportation in people's daily life, and based on the requirements of environmental protection, new energy technologies based on electricity have been actively applied. Insufficient in terms of power and endurance, electric and fuel hybrid vehicles have emerged as the times require. [0003] At present, automatic transmissions have been more and more widely used in the automotive industry, and due to the advantages of compact structure, good fuel economy, large transmission torque, good starting performance and shifting quality, dual-clutch automatic transmissions have become the current research field in the field of interna...
