Description
Technical field
The present invention relates to silicon oil clutch fields, and in particular to a kind of electric-controlled silicon oil clutch.
Background technology
Silicon oil filled fan clutch, uses silicone oil as medium, and torque is transmitted using silicone oil shearing viscous force.The rotating speed of fan is to examine
What worry designed under conditions of when use condition is most severe, guarantee engine does not overheat, therefore, in the usual driving process of vehicle,
The rotating speed of fan should be controlled in proper range, noise could be reduced in this way, improve engine economy.Inside clutch
Seal toughness fluid（Silicone oil）, shear viscous force by it and transmit torque, bimetal leaf is housed before traditional clutch, is incuded with it
By the air themperature of radiator, fan work intracavitary silicone oil amount is thus controlled, only if necessary, could transmit torque makes wind
Fan rotation.
The structure of silicon oil filled fan clutch includes drive shaft, and drive shaft is equipped with actively by driven by engine in the left end of axis
Disk, it is rotated with drive shaft with being fixed in drive shaft；Being additionally provided in drive shaft can be relative to the clutch of drive shaft turns
Device shell and protecgulum are equipped with working chamber and oil storage chamber between both, and driving disc spacing pressing is located in working chamber, equipped with high in oil storage chamber
The silicone oil of viscosity.Fuel feed hole on oil storage chamber is closed by control valve block at room temperature, and the silicone oil of oil storage chamber cannot flow into work at this time
Make intracavitary.Without silicone oil in working chamber, the torque on driving disc spacing pressing cannot pass on protecgulum completely, and clutch is in discrete state.
When engine load increases, and coolant temperature increases, also increased by the temperature of radiator core air-flow.
High temperature gas flow is blown on bimetallic temperature detector, makes bimetal leaf temperature distortion, band moving valve plate trundle and control valve block deflection one
A angle.Gas flow temperature is more than after 65 DEG C, and the fuel feed hole on oil storage chamber is opened, and the silicone oil in oil storage chamber enters work by this hole
Make in chamber.The silicone oil of viscosity flows into the gap between driving disc spacing pressing and protecgulum, and the torque on driving disc spacing pressing is transmitted to protecgulum and clutch
Device shell drives fan high speed rotation, clutch to be now in engagement state.Into working chamber silicone oil centrifugal force effect
Under get rid of to outer rim, oil storage chamber is flowed back to by the oil return hole on protecgulum, then enters back into working chamber.Repeatedly, cycle is formed.Silicon
Heat is transmitted to the gelled protecgulum of casting and clutch outer member in cycle and is cooled down by oil, to avoid silicone oil temperature when work
Spend height.When engine is because of the reasons such as load decline, when blowing to the gas flow temperature of bimetal leaf temperature detector less than 35 DEG C, control valve
Piece is by oil inlet bore closure, and silicone oil does not enter back into working chamber, and the silicone oil in working chamber was still constantly in centrifugation force effect originally
Lower return oil storage chamber, until emptying.Clutch is in discrete state, fan slipping again at this time.
But bimetal leaf sense temperature often has certain hysteresis quality, just will produce after needing temperature to heat it dynamic
Make, sensitivity is relatively low, therefore just has the control valve block by Electromagnetic Control, is axis by the original rotation opening variation of valve block
To slide-open, as soon as and control valve block fixation often push rod end setting card slot card on clamp spring realize installation, this
So that card slot processing when axial required precision it is just very high, the power of push rod is derived from armature in addition, this to armature with push away
There has also been high requirements for fixed position between bar so that process and assemble is more difficult, most it is intuitive influence be exactly can not be
Axial position of the valve block on push rod is rationally adjusted when assembly, especially after the completion of armature is fixed, the direct shadow in fixed position
It rings and arrives the distance between armature and clamp spring, such as apart from too short, armature rate may can be caused when valve block resets under the action of the spring
First offseting with drive shaft causes valve block that can not completely close；Such as apart from long, valve block can be made to be closed completely under the reset of spring
It closes and still there are gaps between clamp spring and valve block so that push rod has certain invalid gap at work；Simultaneously because
The valve block of Electromagnetic Control is by attracting armature realization action, it is therefore desirable to allow magnetic field to be formed into a loop at armature position, and pass
The drive shaft of system should keep intensity, holding magnetism isolating effect in need, therefore pass through using in drive shaft middle position
The mode of friction welding (FW) is connected with one section of magnetic separator, such as stainless steel material, but this can make the processing of drive shaft become tired
Difficulty, processing cost ramp, especially at home under current machining environment, friction welding apparatus be equipped with it is not comprehensive, because
This many drive shaft just needs the manufacturer for spending high processing cost to go for complete friction welding (FW) processing to be produced so that from
Clutch entirety production cost goes up.
Invention content
Based on the above issues, low present invention aims at a kind of drive shaft processing cost is provided, rigidity is strong, magnetism isolating effect
