Detailed Description
The invention will be further elucidated with reference to the drawings and the specific embodiments.
As shown in fig. 1 and fig. 2, a temperature control silicone oil fan clutch with stepless speed regulation function, which comprises: the device comprises a driving shaft 1, a bearing 2, a shell 3, a driving plate 4, a cover body 5, a driven plate assembly 6, a valve sheet shaft 7, a temperature sensing sheet 8, an oil storage cavity 9 and a working cavity 10;
as shown in fig. 3, the driven plate assembly 6 is composed of a driven plate 42, a valve plate 43 and a rivet 40, wherein the valve plate 43 is provided with a cylindrical boss 51, the driven plate 42 is provided with an oil outlet 52, and the cylindrical boss 51 is attached to or separated from the oil outlet 52 to open or close the oil outlet 52.
Examples
When the temperature of the engine coolant rises, the temperature of air flow passing through the radiator core part rises along with the rise of the temperature of the engine coolant, high-temperature air flow blows on the temperature sensing piece 8, the temperature sensing piece 8 is deformed by heating, the valve piece shaft 7 is pushed to move towards the direction far away from the driven plate assembly 6, when the temperature of the air flow exceeds T1 ℃, the cylindrical boss 51 on the valve piece 43 starts to be gradually separated from the oil outlet 52, when the temperature of the air flow reaches T2 ℃ (T2> T1), the cylindrical boss 51 is completely separated from the oil outlet 52, and silicone oil in the oil storage cavity 9 starts to enter the working cavity 10 to drive the fan to rotate;
when the temperature of the engine coolant is reduced, the temperature of the air flow passing through the radiator core is reduced, the air flow blows on the temperature sensing piece 8, the temperature sensing piece 8 deforms and recovers, the valve plate shaft 7 is pushed to move towards the driven plate assembly 6, when the temperature of the air flow reaches T2 ℃, the cylindrical boss 51 and the oil outlet on the driven plate 42 are closed, the silicon oil in the oil storage cylinder 9 does not enter the working cavity 10 any more, the silicon oil in the working cavity 10 returns to the oil storage cavity 9 under the action of centrifugal force until the silicon oil is emptied, the clutch is in an emptying state again, and the fan idles and slips.
As shown in fig. 4 and 5, h is a coupling optimization correction value, and after the height of h is increased, h effectively shortens the coupling time, so that coupling can be accelerated at the coupling end, and the overheating phenomenon of the engine can be avoided.
