Description
Technical field
The utility model relates to silicon oil clutch fields, and in particular to a kind of fine adjustment type electric-controlled silicon oil clutch.
Background technique
Silicon oil filled fan clutch, uses silicone oil as medium, transmits torque using silicone oil shearing viscous force.The revolving speed of fan is to examine
What worry designed under conditions of when use condition is most severe, guarantee engine is not overheated, therefore, in the usual driving process of vehicle,
The revolving speed of fan should be controlled in the appropriate range, noise could be reduced in this way, improve engine economy.Inside clutch
It seals toughness fluid (silicone oil), shears viscous force by it and transmit torque, bimetal leaf is housed before traditional clutch, is incuded with it
By the air themperature of radiator, the intracavitary silicone oil amount of fan work 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 by driven by engine, in the left end of axis equipped with actively
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 front cover are equipped with working chamber and oil storage chamber between both, and driving disc spacing pressing is located in working chamber, are provided with height 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 front cover 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 front cover, and the torque on driving disc spacing pressing is transmitted to front cover and clutch
Device shell, drives fan high speed rotation, and clutch is 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 front cover, then enters back into working chamber.Repeatedly, circulation is formed.Silicon
Heat is transmitted to the gelled front cover of casting and clutch outer member in circulation 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 lower than 35 DEG C, control valve
For piece by oil inlet bore closure, silicone oil does not enter back into working chamber, and the silicone oil in working chamber was still constantly acted in centrifugal force 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, can just generate after needing temperature to heat it dynamic
Make, sensitivity is lower, 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 circlip 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 fixation 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, fixes the direct shadow in position
It rings and arrives the distance between armature and circlip, such as apart from too short, armature rate may be will cause 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 too long, valve block can be made to close completely under the reset of spring
Close and between circlip and valve block still there are gaps so that there is certain invalid gap at work in push rod.
Utility model content
