Description
Technical field
The present invention relates to the silicon oil filled fan clutch of automobile-use.
Background technique
Silicon oil filled fan clutch as medium, utilizes the full-bodied characteristic transmitting torque of silicone oil with silicone oil.Utilize the temperature of radiator back air, control the separation and the joint of fan clutch by temp-sensitive apparatus automatically.When temperature was hanged down, silicone oil did not flow, and fan clutch separates, and rotation speed of the fan slows down, and was idle running basically.When temperature was high, the viscosity of silicone oil made the fan clutch combination, so fan and water pump spindle rotate together, played the effect of regulating engine temperature.Silicon oil filled fan clutch, heat responsive element all are double metal spiral spring temp-sensitive apparatuss.
Its working procedure:
(1) when the air temperature of the radiator of flowing through raises, the temperature distortion of bimetal temp-sensitive apparatus forces valve shaft to rotate, and opens oil inlet hole on the follower plate.The silicone oil of storing between follower plate and the protecgulum just flows into the active chamber between active plate and the follower plate, clutch, and rotation speed of the fan raises.Air temperature is high more, and the oil inlet hole aperture is big more, and rotation speed of the fan is just fast more.
(2) when the air temperature of the radiator of flowing through descended, the bimetal temp-sensitive apparatus restored to the original state, and valve block is closed oil inlet hole, and under action of centrifugal force, silicone oil returns shoe cream room through spill port from active chamber, clutch separation, and it is very low that rotation speed of the fan becomes.
The shortcoming that this silicon oil filled fan clutch exists, when rotation speed of the fan reaches certain rotating speed, after temperature is reduced under the certain limit, this moment as can not in time fan be adjusted to the slow-speed of revolution, then can the consumption of engine more energy, do not meet energy-conserving and environment-protective.
In order to solve this shortcoming, released again in these 2 years and to utilize temperature simultaneously and to survey the silicon oil filled fan clutch that rotation speed of the fan is controlled.By being set, the rotation speed of the fan detection components realizes surveying rotation speed of the fan on follower plate.The rotation speed of the fan velocity package utilizes hall principle to test, and it comprises Hall element, permanent magnet and signal circuit.Usually the solenoid electric valve switch block place at silicon oil filled fan clutch that takes is integrated with the rotation speed of the fan velocity package together.The shortcoming of this structure is: because the solenoid electric valve switch block includes a magnetic coil, and the hall principle that the rotation speed of the fan velocity package adopts, it also includes a permanent magnet, when testing the speed, the strong magnetic field that the magnetic coil of energising produces can be brought certain influence to the field signal that Hall element is accepted, a little less than causing magnetic signal to change, Hall element can't receive normal magnetic signal, cause the rotating speed measured inaccurate, export to the rotary speed data error of central processing unit (CPU), cause the central processing unit (CPU) adjustment to incur loss through delay or not can adjust, the energy of consumption of engine is unfavorable for energy-conserving and environment-protective.
Summary of the invention
