Referring to fig. 1 to 7, the present embodiment includes:

The periphery of the driving shaft 5 is also provided with a wire harness 7, and the wire harness 7 is positioned at the lower end of the shell 4.
The clutch assembly is fixed in engine front end train, water pump axle or bent axle through driving shaft 5 on, driving shaft 5 begins work through the output torque who obtains the engine, and driving shaft 5 and driving plate 3 relatively fixed simultaneously, when the driving shaft is rotatory, the driving plate carries out synchronous revolution with the driving shaft, and pencil 7 is connected fixedly in engine ECU signal output part.
The driving shaft 5 is internally provided with a sliding block 8, a sealing block 9 and a piston rod 10, the sliding block 8 is arranged at the upper end of the sealing block 9, the piston rod 10 is arranged between the upper parts of the sliding blocks 8 and extends upwards to be connected with the valve plate assembly 6, the periphery of the piston rod 10 is sleeved with a spring 11 and a copper sleeve 12, and the spring 11 is positioned between the valve plate assembly 6 and the copper sleeve 12.

The outer ring of the driving plate 2 is designed with an oil blocking and returning structure, and forms a sealed oil returning cavity with the front cover 1 and the shell 4. When the engine sends a cooling instruction through the ECU module, the wire harness 7 is powered off, the magnetic force is weakened, and the valve plate assembly 6 is changed from a normally closed state to a normally open state under the elastic force action of the spring 11. Silicon oil in the oil storage cavity is thrown out through the oil outlet hole under the action of centrifugal force and enters the working cavity, so that the clutch can run at high speed, and when the water temperature of the engine is in a normal temperature range, the wiring harness 7 is electrified. When the wire harness 7 is electrified, the sliding block 8 is attracted by the sealing block 9 under the action of magnetic force and moves downwards, meanwhile, the spring 11 is compressed, and the valve plate assembly 6 is changed from a normally open state to a normally closed state.

The working principle is as follows:
when the wiring harness is electrified, the spring 11 rebounds to open the valve plate assembly 6, silicone oil is thrown out of the oil storage cavity through the oil outlet under the action of centrifugal force and enters the working cavity, and meanwhile, under the action of centrifugal force, the silicone oil passes through the oil scraping channel on the driving plate 2 and penetrates through the oil return hole to be returned to the oil storage cavity, so that an oil circuit circulation is formed, as shown in fig. 3, and arrows in the drawing indicate the oil circuit circulation.
When the wiring harness is electrified, magnetic force is transmitted to the driving shaft 5 through the wiring harness 7 and then transmitted to the sliding block 8, meanwhile, the sliding block 8 is transmitted back to the driving shaft 5 through the sealing block 9, and an isolation sleeve 53 is embedded in the middle of the driving shaft 5, so that a closed loop is formed, as shown in fig. 4, and an arrow in the figure represents magnetic circuit circulation.
