Fan clutch for various types, various brands, various engines, mainly in silicone oil as the medium.
Beijing Jeep fan clutch and Honda CRV.
Fan clutch, with silicone oil as the medium, the use of high viscosity of the characteristics of the transmission torque. Use the temperature of the air behind the radiator, and automatically control the separation and engagement of the fan clutch through the thermostat.. When the temperature is low, silicone oil does not flow, fan clutch, fan speed slow, basically is idle. When the temperature is high, the viscosity of the silicone oil makes the fan clutch, so the fan and the pump shaft rotate together, and play a role in regulating the engine temperature..
The temperature element of the fan clutch is the temperature sensor of the bimetallic coil spring.. Its working process:
(1) when the flow through the radiator of the air temperature rises, the double metal sense temperature thermal deformation, forces the valve spool to rotate and open the driven plate oil inlet hole. The silicone oil which is stored between the driven plate and the front cover flows into the working chamber between the active plate and the driven plate, and the clutch is engaged and the fan speed is increased. The higher the temperature of the air inlet opening angle, the greater the fan speed, the faster the.
(2) when the flow through the radiator of the air temperature decreased, the double metal sense temperature restitution, close the valve oil inlet hole, under the action of centrifugal force, silicone oil return oil chamber from the working chamber through the return oil hole, the separation of the clutch, fan speed become very low.
