Technical field
The utility model relates to the silicon oil filled fan clutch in the car engine cooling system, is specially the oil-way system of silicon oil filled fan clutch.
Background technique
Energy saving is a long-range policy of national economic development.Show according to interrelated data, the energy consumption of automobile 5 ~ 10% is on the fan cooled of motor, and in fact the most of the time of motor car engine work is not need fan cooled, generally have only time of 5 ~ 10% just to need fan cooled, so in the prior art, have a kind of silicon oil filled fan clutch, adopted the engine blower of this clutch, can be so that fan when need cooling off, motor be just started working, and fan was not worked when motor did not need to cool off.
Existing automobile silicon oil filled fan clutch, its structure is: comprise main shaft, fixedly connected protecgulum and bonnet, be arranged between protecgulum and the bonnet and be fixed in main shaft active plate, be arranged at the oil-way system in protecgulum, bonnet, the active plate; Described oil-way system comprises the shoe cream room that is used to store silicone oil, is used for the clutch protecgulum, the power cavity of bonnet and active plate, be used to be connected the oil inlet hole and the spill port of shoe cream room and power cavity; Filler opening place correspondence at the oil inlet hole of described oil-way system is provided with valve block, this valve block links to each other with a temperature sensing device, this temperature sensing device can be experienced the air temperature that blows from radiator and produce thermal distortion and drives the valve block action, and then the opening and closing of the filler opening place of control oil inlet hole.Its working principle is: the amount of deformation that produces when temperature sensibility is subjected to air stream and is heated to uniform temperature point will impel the valve block in the clutch to open oil inlet hole, thereby the silicone oil in the shoe cream room will enter into power cavity through oil inlet hole under centrifugal action, because silicone oil viscosity is bigger, power cavity is the chamber that forms between active plate and protecgulum and/or bonnet, so after entering silicone oil in the power cavity, make the rotation of active plate to drive protecgulum and bonnet rotates together, and then drive the fan rotation that is fixed on protecgulum, the bonnet outside; Silicone oil in the power cavity is many more, and the moment of clutch transmits is big more, and the slippage of clutch is also more little, so at this moment the rotating speed of fan correspondingly gets a promotion, air quantity increases; When the airflow temperature that is subjected to when temperature sensibility reduces, its amount of deformation will reduce even not to be enough to make valve block open valve opening, thereby stoped the silicone oil that is stored in the shoe cream room to enter into power cavity, silicone oil in the power cavity will be back to shoe cream room by spill port under centrifugal action, silicone oil in the power cavity reduces like this, and the moment of clutch transmits diminishes, and slippage increases, rotation speed of the fan reduces, and air quantity reduces.Like this, can reach, make and when engine overheat, just open the fan heat radiation, save the energy according to the purpose that the air temperature that blows from radiator is judged and the control fan rotates or stops.But, but there is following defective at work in this fan clutch: 1, because the thermal air current temperature is not real engine water temperature, therefore when the control rotation speed of the fan, the temperature-sensitive control system can not really detect and reflect the situation of motor actual water temperature, so just be easy to make motor to be in cold or overheated working state, therefore the response time of fan has certain hysteresis, thereby causes the control accuracy of clutch to be affected.2, there are the characteristics of response lag in the thermal distortion physical property instability of temperature sensibility, so controls insensitive.3, two states is only opened and closed to the valve block on the traditional clutch, therefore also can only control fan changes between two kinds of rotating speed states, promptly at a high speed and low speed, it can not satisfy the demand of motor to other rotation speed of the fan, and the switching of gear is too obvious when switch transition, is difficult to accomplish smooth adjustment.When 4, temperature sensibility lost efficacy, may exist valve block to close the situation of dead valve opening fully, cause rotation speed of the fan under lower-speed state, to move all the time, so the reliability of clutch, Security are not high.5, clutch can't detect the rotating speed of fan, so motor can not real-time monitor the rotating speed of fan in running, and this has also reduced the Security of clutch work.6, because valve opening and shoe cream room all are arranged on the protecgulum, the rotating speed of protecgulum, bonnet and fan is the same, and when rotation speed of the fan was low, because the centrifugal force of shoe cream room is very little, so silicone oil was also very little by the power that valve opening enters into power cavity, so cause fan by low speed when high speed changes, response time is long, and the easy like this clutch delay of response when speed change that occurs has been incured loss through delay cooling time, cause that engine water temperature is higher, to such an extent as to influence the motor proper functioning.

The working principle of this silicon oil filled fan clutch:
When control system 18 is cut off the power supply electromagnet mechanism, electromagnet does not have magnetic field and produces, be that electromagnet mechanism does not produce magnetic force to armature 11, at this moment valve block 10 is in separated state with oil-feed valve opening 7, be that oil-feed valve opening 7 is opened, at this moment the silicone oil in the shoe cream room 5 flows in the power cavity 6, so the rotating speed of fan is very fast.But because the effect of limiting stopper 13, after armature 11 upwards rotated and pushes against with limiting stopper 13, valve block 10 just can't rotate bigger angle, the open degree maximum of the valve opening of oil-feed at this moment 7.
After control system 18 is to the electromagnet mechanism energising, electromagnet will produce magnetic field around main shaft 1,1 pair of armature of main shaft 11 produces magnetic force and draws armature over to one's side immediately, at this moment armature 11 drives the fulcrum rotation of valve block 10 on active plate 4 of the other end, and then make valve block 10 approaching with the oil-feed valve opening 7 on the active plate 4, at this moment the open degree of oil-feed valve opening 7 reduces; If control system 18 further increases the electric current on the electromagnet, the suction of 1 pair of armature 11 of main shaft will increase and finally make valve block 10 with 7 sealings of oil-feed valve opening, enter into silicone oil in the power cavity 6 in this process and will reduce gradually and finally stop oil-feed, so the rotating speed of fan also slows down accordingly.
The control system 18 of this silicon oil filled fan clutch is when the rotating speed of control fan, be the suction of realizing changing 1 pair of armature 11 of main shaft by the size of current in the coil on the control electromagnet, thereby the angle that control valve block 10 rotates, reach the purpose of the open degree of control oil-feed valve opening 7, so just realized the rotating speed of smooth adjustment fan, controlled also more accurate.When the electric current on the electromagnet reduced, the suction of 1 pair of armature 11 of main shaft also reduced accordingly, and at this moment armature 11 will rotate up return under the self gravitation effect, equally also can drive valve block 10 and rotate, and promptly realized the increase of oil-feed valve opening 7 open degree.
From the working procedure of this silicon oil clutch as can be seen, when oil-way system of the present utility model is worked, the kinetic energy that rotates by active plate on the main shaft can provide enough power supports to the silicone oil in the whole oil-way system is mobile, makes fan clutch when speed change to react rapidly like this; And the advantage that the silicon oil clutch that adopts the utility model oil-way system also has adjusting rotation speed of the fan that can be level and smooth simultaneously and can blow according to the actual air volume demand of motor, this makes clutch obvious especially to the refrigeration of motor car engine.
