Embodiment Construction
[0015] Combine below figure 1 And further illustrate the technical solution of the present invention through specific examples.
[0016] A temperature-controlled silicone oil fan clutch, comprising: a central shaft 1, a flange 2, a fan blade fixed disc 16, a first clutch plate 17 and a second clutch plate 6, the flange 2 is arranged behind the central shaft 1 end, the blade fixed disk 16 is set on the central shaft 1, and the central shaft 1 is provided with the first bearing 3 located in the inner hole 16 of the blade fixed disk, and the blade fixed disk 16 is connected with the flange 2 is provided with a second bearing 4, so that the fan blade fixed disk 16 is not directly affected by the rotation of the central shaft 1.
[0017] The first clutch plate 17 is concentrically arranged on the front of the blade fixed plate 16, the second clutch plate 6 is located in front of the first clutch plate 17, when the second clutch plate 6 is combined with the first clutch plate 17, t...

The invention discloses a temperature-controlled silicone oil fan clutch. The temperature-controlled silicone oil fan clutch comprises a middle shaft, a flange plate, a blade fixing disc, a first clutch plate and a second clutch plate, wherein the middle shaft is provided with a silicone oil control disc located in front of the second clutch plate, a first oil storage cavity and a second oil storage cavity are annularly formed in the silicone oil control disc, the first oil storage cavity is provided with a plurality of piston holes pointing to the second clutch plate, the outer side of the second clutch plate is provided with piston posts extending into the piston hole, the front end of the middle shaft is provided with a washer and a bolt, a dual metal plate extending to the position infront of the silicone oil control disc is arranged between the bolt and the washer, and a valve element vertically inserted into an oil feeding channel is arranged on the dual metal plate. According to the temperature-controlled silicone oil fan clutch, the end part of the dual metal plate curled inwards when the dual metal plate is heated, accordingly the valve element is moved forwards to open the oil feeding channel, oil pressure of the first oil storage cavity is increased, the piston posts are driven to move outwards, and thus the first clutch plate and the second clutch plate are combined gradually.
Description
technical field [0001] The invention relates to the field of clutches, in particular to a temperature-controlled silicone oil fan clutch. Background technique [0002] Silicone oil fan clutches are mainly used in automobiles. During the driving process of the automobile, due to changes in environmental conditions and operating conditions, the thermal condition of the engine is also changing, and the cooling intensity of the engine needs to be adjusted at any time. [0003] In the hot season, the engine works at low speed and under heavy load, the temperature of the coolant is high, the fan should rotate at high speed to increase the cooling air volume and enhance the heat dissipation capacity of the radiator, while in the cold season, when the temperature of the coolant is low, Or when the car is running at high speed and there is a strong headwind blowing through the radiator, it becomes meaningless for the fan to continue to work, which not only consumes the engine power i...
