The design is related to automobile industry, is suitable for all using engine as the vehicle in fan power source, and in particular to one
The system that kind promotes silicon oil filled fan clutch control performance, the system are built upon on the basis of electric-control silicone oil fan clutch,
For solving 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, the mechanical clutch is single by electronic control
Member is controlled by solenoid valve and pneumatic device or other devices that the shift fork of mechanical clutch can be made to move back and forth；When setting wind
When fan rotating 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
Operation 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, does not need excessive radiating efficiency at all at this time to reduce coolant temperature, excessive radiating efficiency,
Coolant temperature can be prevented from reaching the ideal working temperature of engine instead（88℃）；Engine operating temperature is too low, can lead
It causes engine oil viscosity excessive, 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, 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, engine friction horsepower is reduced.The original being not completely separated due to electric-controlled silicon oil clutch
Cause, in the lower environment of atmospheric temperature, the operating of fan can cause coolant temperature relatively low（Certain truck is in -35 DEG C of environment temperature
Under degree, coolant temperature is only balanced to 65 DEG C or so）, as shown in Figure 6, Figure 7, certain four-cylinder diesel engine with coolant temperature liter
Height, frictional work are 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, fan attachment work(is reduced.In the case that unnecessary, wind is kept completely separate using the device
Fan clutch reduces the attachment work(of fan to make rotation speed of the fan be down to 0 rev/min；Fan attachment work(is with rotation speed of the fan
Situation of change is as shown in figure 8, according to the cold area's test result of certain vehicle, 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, after vehicle is using device described in the design, the reliability level of engine also has corresponding promotion.Hair
Motivation lubricating oil viscosity 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, to influence to lubricate
Effect shortens the service life of engine, influences vehicle reliability.

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 in Han Qu or engine start.So the effect of mechanical clutch is exactly, when need
It is 0 to want rotation speed of the fan, or when needing rotation speed of the fan ＜ 500RPM, we are just by power cut from the power transmission of physics.
