Description
Technical field
The utility model design engine-cooling system assembly, particularly relates to a kind of fan clutch.
Background technology
In the process of moving, due to environmental condition and the change of operating condition, the hot situation of engine is also changing automobile.
Therefore, it is necessary to regulate the intensity of cooling of engine at any time.Such as, during the broiling summer, engine is at low speed, big load
Lower work, when the temperature of coolant is the highest, fan should High Rotation Speed to increase cooling air quantity, strengthen radiator heat radiation
Ability；And in cold winter, when coolant temperature is relatively low, or there have powerful head-on wind to blow at galloping to be scattered
During hot device, then fan can need not work.
To this end, occur in that a kind of fan clutch, existing clutch for silicone oil fan of automobile, its structure is: include actively
Axle, the fixing protecgulum connected and housing, be arranged between protecgulum and housing and be fixed on main shaft driving disc spacing pressing, be arranged at before
Oil piping system in lid, housing, driving disc spacing pressing；Described oil piping system includes the shoe cream room for storing silicone oil, for clutch
Protecgulum, housing engage chamber, for being connected shoe cream room and the fuel feed hole in engagement chamber and spill port with driving disc spacing pressing；At described oil
Being correspondingly arranged on valve block at the oil-in of the fuel feed hole of road system, this valve block and a temperature sensing device are connected, this temperature sensing device
The air themperature blown from radiator can be experienced and produce thermal deformation and carry out band moving valve plate action, and then controlling the oil-feed of fuel feed hole
Opening and closing at Kou.
Its operation principle is: the deflection produced when temperature sensibility is heated to uniform temperature point by air stream will promote clutch
Valve block in device opens fuel feed hole, thus the silicone oil in shoe cream room will enter into engagement through fuel feed hole under centrifugal action
Chamber, owing to silicone oil viscosity is relatively big, engagement chamber is the chamber formed between driving disc spacing pressing and protecgulum and/or housing, therefore when nibbling
After conjunction chamber enters silicone oil so that before the rotation of driving disc spacing pressing can drive protecgulum to rotate together with housing, and then drive is fixed on
Lid, the fan of hull outside rotate；Silicone oil in engagement chamber is the most, and the moment of clutch transmission is the biggest, the cunning of clutch
Difference is the least, so at this moment the rotating speed of fan is correspondingly made available lifting, air quantity increases；When the air stream temperature that temperature sensibility is subject to
When degree reduces, minimizing is even less than so that valve block opens valve opening by its deflection, thus prevents and be stored in shoe cream room
Silicone oil enters into engagement chamber, and the silicone oil in engagement chamber will be back to shoe cream room by spill port, so under centrifugal action
Silicone oil in engagement chamber reduces, and the moment of clutch transmission diminishes, and slippage increases, and rotation speed of the fan reduces, and air quantity reduces.
But, existing fan clutch is generally provided only with a fuel feed hole, on driving disc spacing pressing meanwhile, on driving disc spacing pressing also
It is not provided with any drainage conduit about communicating with this fuel feed hole, therefore, cause and the silicone oil in shoe cream room is gone out by fuel feed hole
The mesh regional being drained between driving disc spacing pressing and protecgulum and housing, its flow velocity is slower so that driving disc spacing pressing and protecgulum and housing
Between supplement abundant silicone oil and need the longer time, thus have impact on the response efficiency of fan clutch.
