The oil pump 3 is an oil pump.
An oil inlet of the pressure release valve 6 is connected with the main oil path 4 through a pressure release valve oil inlet passage 8, an oil return port of the pressure release valve 6 is connected with the upstream end oil path 2 of the oil pump 3 through a pressure release valve oil return passage 5, a first control end of the pressure release valve 6 is connected with the main oil path 4 through a first feedback oil path 7, and a second control end of the pressure release valve 6 is connected with a second oil outlet passage 20 through a second feedback oil path 11;
the opening degree of the relief valve 6 is controlled by the oil pressure difference generated between the hydraulic pressure of the second feedback oil passage 11 and the hydraulic pressure of the first feedback oil passage 7 by the sum of the hydraulic pressure and the spring force of the relief valve 6:
firstly, when the sum of the hydraulic pressure of the second feedback oil channel 11 and the spring force of the pressure release valve 6 is larger than or equal to the hydraulic pressure of the first feedback oil channel 7, the main oil channel 4 does not need to be unloaded, and the pressure release valve 6 is normally closed. At this time, the second flow rate control valve 19 is in an open state, and the oil pump 3 is loaded in the rated operating range. When the clutch corresponding to the first oil outlet channel 12 needs large-flow lubrication, the first flow control valve 13 can be rapidly switched and controlled after the oil pump is started, so that the 'locked-rotor' fault caused by overlarge instantaneous load when the oil pump 3 is started is effectively avoided;

In this embodiment, the first flow control valve 13 is a normally closed solenoid valve, and only when the clutch corresponding to the first oil outlet channel needs a large lubrication flow, the first flow control valve is opened to supplement the lubrication oil, so as to avoid ablation of the clutch.
A second flow control valve 19 is arranged between the second oil outlet channel 20 and the main oil channel 4, the oil inlet end of the second flow control valve 19 is connected with the main oil channel 4 through a second flow control oil inlet channel 18, and the oil outlet end of the second flow control valve 19 is connected with the second oil outlet channel 20 through an oil pipe; in this embodiment, the second flow control valve 19 is a normally open solenoid valve, and is used to control the second oil outlet channel 20 to supply oil to the clutch at all times or at a large flow rate. The third oil outlet channel 21 is connected with the main oil channel 4 through an oil pipe and is used for lubricating and supplying oil to the shaft teeth.
In this embodiment, the third oil outlet channel 21 is provided with a second throttle 22 for controlling the flow rate of the shaft gear lubrication oil supply.
In this embodiment, the first flow control valve 13 and the second flow control valve 19 are both two-position two-way proportional solenoid valves.
