The principle of the present invention is described as follows：
The design is related to automobile industry, suitable for all using engine as the vehicle in fan power source, and in particular to Yi Zhongti
The system for rising silicon oil filled fan clutch control performance, the system are built upon on the basis of electric-control silicone oil fan clutch, are used for
Solve the problems, such as that electric-control silicone oil fan clutch is not completely separated, principle is as follows：
Install a mechanical clutch additional between fan pulley and fan clutch, which is led to by electronic control unit
Cross the device control that solenoid valve and pneumatic device or other shift forks that can make mechanical clutch move back and forth；When setting fan turns
When speed is 0 rev/min, which is kept completely separate mechanical clutch；When setting rotating speed of fan is more than 0 rev/min, the system operatio
Mechanical clutch makes its engagement；Rotation speed of the fan is still adjusted by electric-controlled silicon oil clutch.
The system can be fully solved the problem of electric-controlled silicon oil clutch is not completely separated.When vehicle runs on cold zone
When, environment temperature is too low, and excessive radiating efficiency is not required at all at this time to reduce coolant temperature, excessive radiating efficiency,
It can prevent coolant temperature instead from reaching the ideal working temperature of engine（88℃）；Engine operating temperature is too low, can lead
It causes engine oil viscosity excessive, so as to increase frictional work, is degrading the economy of vehicle；The excessive machine oil of viscosity is not easy to be formed simultaneously
Effective oil film increases the abrasion between engine friction pair, so as to reduce the reliability of engine.Therefore, using the system
Afterwards, economy and reliability of the vehicle in cold regions can be effectively improved.
Economy promotion is realized by following two aspects：
（1）Leaving water temperature is improved, reduces engine friction horsepower.Due to being not completely separated electric-controlled silicon oil clutch,
In the relatively low environment of atmospheric temperature, the operating of fan can cause coolant temperature relatively low（Certain truck under -35 DEG C of environment temperatures,
Coolant temperature is only balanced to 65 DEG C or so）, as shown in Figure 6, Figure 7, certain four-cylinder diesel engine with the rise of coolant temperature,
Frictional work is gradually reduced, and the reduction amplitude of the engine friction horsepower is about 2 ﹪ of full load power under each rotating speed.
（2）Rotation speed of the fan is reduced, reduces fan attachment work(.In the case that unnecessary, wind is kept completely separate using the device
Clutch is fanned, so that rotation speed of the fan is down to 0 rev/min, reduces the attachment work(of fan；Fan attachment work(is with rotation speed of the fan
Situation of change according to certain vehicle as shown in figure 8, tremble with fear area's result of the test, when fan setting speed is 0, due to electric control silicone oil fan
Clutch is not completely separated, and the actual speed of fan is about 400 revs/min.
In addition, vehicle, using after the described device of the design, the reliability level of engine also has corresponding promotion.Hair
Motivation oil body as the variation tendency of oil temperature is as shown in figure 9, when the engine has the low temperature, engine oil viscosity accordingly compared with
Greatly, this forms effective oil film relative difficulty for the friction surface between engine internal friction pair, so as to influence to lubricate
Effect shortens the service life of engine, influences vehicle reliability.
Spline housing is sleeved on the spline of No.1 splined shaft, No. two splined shafts, and for being driven, band fork slot thereon, shift fork can
It is dynamic between cut-out No.1 splined shaft, No. two splined shafts when it is slided to No. two spline direction of principal axis to manipulate spline housing slip
Power is not driven；When resetting spring is pushed back to No.1 spline direction of principal axis, the spline of spline housing and No.1 splined shaft is connected,
No.1 splined shaft, No. two splined shaft power ONs, transmission.No.1 splined shaft and fan pulley Hard link, can be welded to
An axis on fan pulley, but have the requirement of verticality.No. two splined shafts and fan clutch hard link can be welderings
It connects, No. two splined shafts can use stent to fix on the engine, but have the requirement of concentricity with No.1 splined shaft.No.1 thrust
Piece, No. two thrust plates are respectively necessary for having relative rotation with No.1 splined shaft, No. two splined shafts.Resetting spring is answered for spline housing
Position, cut-out transmission.Shift fork is a lever, and fulcrum is on blower tray, on engine or other positions of vehicle, and the purpose is to dial
Dynamic spline housing.
The course of work describes：
When water temperature is higher than design temperature, it is necessary to which fan is with certain rotation speed operation, at this point, electronic control unit control solenoid valve closes
It closes, pneumatic device gas circuit is closed, and shift fork is failure to actuate, and spline housing connects the power between No.1 splined shaft, No. two splined shafts, fan
Rotating speed is controlled as other engines by controlling the duty cycle of fan clutch；
When water temperature is in starting stage less than design temperature or engine, fan running is not required, at this point, electronic control unit
Solenoid valve is controlled to open, pneumatic device gas circuit is connected（It is compressed air in gas circuit, compressed air can promote shift fork to act）, dial
Fork is promoted by gas circuit, and spline housing is stirred to No. two spline direction of principal axis, the power between cut-out No.1 splined shaft, No. two splined shafts
Transmission, fan is without external force driving, rotating speed zero at this time.
Electric-controlled silicon oil clutch is also controlled by electronic control unit, and the time disengaged is long, in addition will not be complete
Complete to disengage, generally when rotation speed of the fan is less than 500RPM, we are considered as, and its is completely disengaged, but rotation speed of the fan is to drop not always
To 0, this can all bring harmful effect when Han Qu or engine are started.So the effect of mechanical clutch is exactly, when need
Wanting rotation speed of the fan, we are just by power cut from the power transmission of physics for 0 or when needing rotation speed of the fan ＜ 500RPM.
Control switch is SWITCH switches, and centre is Rule of judgment, works as rotation speed of the fan>When 0, solenoid valve is closed, and works as fan
During rotating speed=0, solenoid valve is opened.
The operation principle of stabilization processing unit is：When electronic control unit sends solenoid valve operation（It is turned on and off）Life
When making, which need to continue certain duration, and stabilization processing unit just exports the order, and the purpose is to prevent that solenoid valve is frequent
Operation, such as：Present solenoid valve is closed, and the unlatching of order request solenoid valve is sent after 1s, and 2s requires solenoid valve to close again, so
It is unreasonable.
