Description
Technical field
The utility model relates to a kind of follow-up type electric-control silicone oil fan clutch, belongs to a kind of fan clutch of car engine cooling system.
Background technique
Electric-control silicone oil fan clutch is the temperature being carried out perception cooling liquid by cooling-water temperature transmitter, ECU or special Direct box obtain temperature signal, according to the program of setting, different temperature, exports different electrical signal, by the conversion of electromagnetic signal, electromagnetic force controls the folding of valve rod, change the silicone oil amount of clutch active chamber inside, the final speed controlling fan, reaches the object controlling engine temperature.The control of electric control silicone oil fan is a closed loop control system, Engine ECU or monitoring coolant temperature of special Direct box moment and the rotating speed of fan, thus reaches and make motor keep working at a constant temperature always.Electromagnetic fan clutch is divided into two speed and three speed, and two fast electromagnetic fan clutch, by the break-make of control coil electric current, realize the high and low rotating speed of fan; Three-speed electromagnetic fan clutch, by controlling the break-make of size coil current, realizes high, medium and low three rotating speeds of fan.When middling speed working state, permanent magnet and soft magnetic material produce foucault current by the permanent magnet on soft magnetic material on drive plate and fixed tray, drive fan turns, owing to can generate heat generation high temperature in cutting magnetic line process, when permanent magnet be in for a long time work under high temperature time, magnetic force will be decayed gradually, finally cause clutch to lose efficacy, therefore existence and stability be poor, the defect that life-span is short, in addition permanent magnet is rare earth material, price, and cost is high.
Moreover no matter two speed or three-speed electromagnetic fan clutch, when cooling medium is in the condition of high temperature, electromagnetic coil is all energized, adhesive dish is instantaneous to be pull-in on drive plate, produces powerful impact force, and due to the inertia force of High Rotation Speed, rub between adhesive dish and drive plate and produce spark, produce very big noise and there is potential safety hazard, clutch is separated frequently, adhesive, accelerate the wearing and tearing of adhesive dish and drive plate, cause clutch to lose efficacy, affect working life.
Silicon oil filled fan clutch control speed method, one is the change generation motion of temperature feeling ring along with coolant temperature, and mesh control chamber participates in the silicone oil amount of engagement, thus changes the rotating speed of fan, the temperature of reduction cooling medium.Two is that Engine ECU derives coolant temperature signal, makes electromagnetic coil energising and the power-off of clutch, and then the opening or closing of control valve, and drives the high, low speed of fan to rotate, reduces coolant temperature., all there is the state of cooling and the unmatched situation of the actual state of cooling of motor needs, make engine cooling medium too high or too low for temperature in these two kinds of silicon oil clutchs.The working state of motor the best be coolant temperature between 85 ~ 95 DEG C, coolant temperature is too low, the working temperature environment of motor off-target, increases friction, strengthens oil consumption, deterioration of emission; Coolant temperature is too high, and while cooling medium is vaporized, form high pressure, each parts of motor can not get effective cooling, occur the phenomenons such as motor card cylinder, affect vehicle operating.
Summary of the invention
