When the electromagnetic valve 6 controls the valve plate 5 to open and close the oil outlet 41, the clutch has the advantages of simple structure, lasting and effective opening and closing functions and convenience in effectively controlling the clutch operation of the automobile cooling fan. The electromagnetic valve 6 is positioned on one side of the rear shell 2 far away from the driving plate 4 and is fixedly connected with the driving shaft 3. It should be noted that an oil outlet chamber 43 communicating with the oil outlet 41 and the inside of the active plate 4 is provided in the oil storage chamber 12. The valve plate 5 includes an elastic connecting piece 51 matching the oil outlet chamber 43 and an oil blocking joint 52 matching the oil outlet 41. Both ends of the elastic connecting piece 51 are connected to the middle portion of the driving plate 4 and the oil blocking joint 52, respectively. And the solenoid valve 6 comprises a coil actuator 62 connected to the driveshaft 3 and a wiring harness 63 electrically connecting the coil actuator 62 and the electronic control unit of the automobile engine. And an electromagnetic core 61 which is linked with a coil actuator 62 to drive the elastic connecting sheet 51 to open and close the oil outlet 41 is arranged in the rear shell 2.

It should be mentioned that, the length direction of interior oil diffusion groove 49 radially sets up along drive plate 4, and the length direction of outer oil diffusion groove 45 and the radial cross arrangement of drive plate 4, and then will play the length that increases outer oil diffusion groove 45 and make the effect that the moving speed of silicon oil in outer oil diffusion groove 45 slows down, further promote the rotational acceleration stability of preceding lid 1 and back casing 2, show the stability that promotes car radiator fan rotational speed control.
As shown in fig. 2, 6 and 7, a plurality of rear-housing oil immersion passages 22 are provided in the rear-housing engagement ring groove 21 of the rear housing 2 and are distributed in an equal arc, and an adapter shaft 23 is rotatably connected to the middle portion of the rear housing 2 and is inserted into and fixed to the electromagnet core 61. The rear shell immersion oil duct 22 plays a role in lifting and guiding the silicone oil to fully immerse the rear shell meshing ring groove 21 and guiding the silicone oil to move towards the outermost end of the rear shell meshing ring groove 21 when the silicone oil flows back, and therefore the backflow efficiency of the silicone oil is remarkably improved.
As shown in fig. 2, 8, and 9, an oil return hole 461 is provided coaxially with the oil outlet passage 42 on the outer side of the driving plate 4. An arc-shaped oil return groove 16 is formed at the outer end of the inner side of the front cover body 1, and an oil removal hole 161 is formed at the front end of the oil return groove 16. The inner end of the front cover body 1 is provided with an oil return port 13 communicated with the oil removing hole 161 and the oil storage chamber 12. Therefore, after the silicon oil in the driving engagement ring groove 44 moves away from the axis of the driving plate 4 due to centrifugal force, the silicon oil moves to the edge of the peripheral side wall of the driving plate 4, and when the driving plate 4 contacts with the front end of the oil return groove 16 of the front cover body 1 to generate an oil cutting effect, the silicon oil on the side wall of the driving plate 4 is scraped into the oil return groove 16, and then flows back to the oil storage cavity 12 through the oil removing hole 161 and the oil return hole 461 at the front end of the oil return groove 16, so that the whole backflow process is orderly and efficient.
It should be mentioned that a plurality of front cover oil immersion passages 15 are provided on the front cover engagement ring groove 14 of the front cover body 1 and are distributed in an equal arc. The front cover oil immersion channel 15 plays a role in lifting and guiding the silicon oil to fully immerse the front cover meshing ring groove 14 and guiding the silicon oil to move towards the outermost end of the front cover meshing ring groove 14 when the silicon oil flows back, and the backflow efficiency of the silicon oil is further improved. Meanwhile, a oil supply groove 162 having a depth greater than that of the oil return groove 16 is provided at the rear end of the oil return groove 16. The oil supply groove 162 serves to further store the silicone oil cut by the oil at the front end of the oil return groove 16, and the backflow efficiency of the silicone oil is remarkably improved. In order to guide the silicone oil on the side of the active plate 4 facing the rear housing 2 to move toward the front cover 1, an outer inclined groove 48 inclined toward the rear end of the oil return groove 16 and guiding the silicone oil is provided on the outer peripheral side wall of the active plate 4. When the driving plate 4 rotates, the silicone oil located inside the driving plate 4 flows to the outside of the driving plate 4 under the action of the outer chutes 48 and the centrifugal force, i.e. flows from the backward-facing side to the front cover body 1, and then the ordered and efficient silicone oil backflow effect is achieved under the oil cutting action of the oil return groove 16.
