A fan clutch device for an engine according to an embodiment of the first aspect of the present invention will be specifically described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, a fan clutch device for an engine according to an embodiment of the first aspect of the present invention includes: a housing 10, a partition plate 20, an active plate 30, a rotating shaft 40, and a control assembly.

Specifically, the housing 10 is provided with a chamber, and the rear end of the housing 10 is provided with an opening. The partition 20 is disposed in the chamber and divides the chamber into the oil storage chamber 11 and the working chamber 12, and the working chamber 12 and the opening guide The switch 20 is provided with a switch for controlling the flow of oil in the oil storage chamber 11 and the working chamber 12. The active plate 30 is pivotally mounted in the working chamber 12, and one end of the rotating shaft 40 extends into the working chamber 12 from the opening. The rotating shaft 40 is connected to the driving plate 30 and drives the driving mechanism 30 to rotate, and the control component is disposed in the housing.

At 10, the control unit controls the switch to open and close, and the oil in the oil reservoir 11 enters the working chamber 12 and is driven by the driving plate 30 to drive the housing 10 to rotate.

Thus, according to the fan clutch device for an engine according to an embodiment of the present invention, by providing a control assembly, the control assembly can control the opening and closing of the switch to control the amount of oil entering the working chamber 12 from the oil reservoir 11 and enter When the oil of the working chamber 12 rotates, the casing 10 rotates, so that the rotation speed of the casing 10 relative to the rotating shaft 40 can be controlled, and the speed control of the driving target speed can be realized, which can greatly reduce the energy consumption of the cooling fan, etc. The engine performs precise thermal management.

It should be noted that the rotating shaft 40 may be a crankshaft of the engine, and the engine driving rotating shaft 40 rotates at a certain speed. The driving plate 30 is connected to the rotating shaft 40 and is rotated in the working chamber 12 under the driving of the rotating shaft 40.

Rotating; when the switch is opened, the amount of oil in the oil storage chamber 11 can be controlled to flow into the working chamber 12 through the partition plate 20. Since the oil is viscous, the active plate 30 will drive the oil when rotating and The housing 10 rotates, and as the amount of oil in the working chamber 12 increases, the greater the force that the active plate 30 drives the housing 10 to rotate, the faster the rotational speed of the housing 10. The amount of oil entering the working chamber 12 in the oil reservoir 11 can be controlled by the switch, so that the rotational speed of the housing 10 relative to the rotating shaft 40 can be controlled, and the control unit can control the opening and closing of the switch, which is equivalent to controlling the switch through the control unit. The rotation speed of the housing 10 can be controlled by opening and closing.

That is, the function of the control assembly is to control the housing 10 relative to the shaft through the oil located in the working chamber 12.

The rotational speed of 40, because the oil has a certain viscosity, when the active plate 30 connected to the rotating shaft 40 rotates, the housing 10 is rotated by the action of the intermediate medium oil, and the rotational speed of the rotating shaft 40 is determined by the rotational speed of the engine, and the housing 10 is relatively The rotational speed of the rotating shaft 40 is adjusted by the rotational speed of the rotating shaft 40 and the control unit. The control assembly functions to adjust the rotational speed of the housing 10 by adjusting the amount of oil in the working chamber 12, because the different amounts of oil drive the housing 10 to rotate under different amounts of force, thereby causing the housing 10 to rotate at a different rotational speed relative to the rotating shaft 40. .
