Embodiment
Below will be by describing an exemplary embodiment of the present invention with reference to the accompanying drawings in detail.
Fig. 1 is the viewgraph of cross-section according to the cooling fan clutch of an exemplary embodiment of the present invention.
As shown in Figure 1, cooling fan clutch according to an exemplary embodiment of the present invention can comprise end cap 10, housing 12, fan 20, rotor 14, operating unit 34, control unit of engine (Engine Control Unit, ECU) 100, and coolant temperature sensor 130.
End cap 10 has the disk profile and has first convexconcave part 40 of the radial outside part that is arranged on an one side surface.
Housing 12 part therebetween is formed with internal surface 36, and this internal surface matches with end cap 10, in order to form certain space with end cap 10.Internal surface 36 is rotatably inserted in rotating shaft 16, is arranged on the radial outside part of a side surface of housing 12 in the face of second convexconcave part 42 of first convexconcave part 40.Bearing 18 is used to reduce the frictional force that relative rotation produced by between them between housing 12 and rotating shaft 16.
Fan 20 is fixedly attached on the housing 12, with housing 12 rotations, in order to freezing mixture is cooled off.
Rotor 14 is rotatably installed in the space between end cap 10 and the housing 12, and the intermediate portion of rotor 14 is connected with rotating shaft 16 keys, thereby with rotating shaft 16 rotations.Be arranged on radial outside two side surfaces partly of rotor 14 with first and second convexconcave parts 40 and 42 corresponding the 3rd convexconcave parts 38 respectively.That is, the projection of the 3rd convexconcave part 38 is inserted among the depression of first and second convexconcave parts 40 and 42, and first and second convexconcave parts 40 and 42 projection are inserted in the depression of the 3rd convexconcave part 38.Under the state of rotor 14 rotation, housing 12 and end cap 10 also rotate by the frictional force between first, second and the 3rd convexconcave part 40,42 and 38.
Operating unit 34 control supplies to the silicone oil amount in the space between end cap 10 and the housing 12, particularly is supplied in the silicone oil amount of first, second and the 3rd convexconcave part 40,42 and 38.Under a large amount of condition of supplying of silicone oil, between rotor 14 and the housing 12 and the frictional force between rotor 14 and the end cap 10 become big, the rotating speed of fan 20 increases.Otherwise, at silicone oil in a small amount under the condition of supplying, between rotor 14 and the housing 12 and the frictional force between rotor 14 and the end cap 10 diminish, the rotating speed of fan 20 reduces.
Control unit of engine 100 comes the operation of operating unit 34 is controlled according to the temperature of freezing mixture.That is, control unit of engine 100 opens or closes operating switch 110 according to the temperature of freezing mixture, correspondingly electric current is provided or does not provide electric current to it to operating unit.
Coolant temperature sensor 130 is surveyed the temperature of freezing mixture and is transmitted corresponding signal to control unit of engine 100.
In addition, the cooling fan clutch according to exemplary embodiment of the present invention further comprises power supply 140 and ignition switch 120.If ignition switch 120 closures, power supply 140 is electrically connected with operating switch 110, if but ignition switch 120 disconnects, and the electrical connection between power supply 140 and the operating switch 110 is cut off.
Fig. 2 is the zoomed-in view that is used in according to the operating unit in the cooling fan clutch of exemplary embodiment of the present invention.
Operating unit 34 comprises reserve 22, baffle plate 24, valve 30, electromagnet 26, sheet metal 32 and valve rod 28.
Reserve 22 is formed in the space between end cap 10 and the housing 12, and silicone oil is stored in the reserve 22.
A surface of baffle plate 24 sealing reserves 22, and the oil circuit 44 that is stored in the silicone oil in the reserve is supplied with in the space that has between end cap 10 and housing 12.If oil circuit 44 is opened, the space of the silicone oil in the reserve 22 between end cap 10 and housing 12 supplied with.Otherwise if oil circuit 44 is closed, silicone oil can not be supplied with.
Valve 30 optionally opens and closes oil circuit 44.
When control unit of engine 100 made operation-control switch 110 closures, the electric current that electromagnet 26 is accepted from power supply 140 produced electromagnetic force.
Sheet metal 32 is installed near the electromagnet 26, by left or right-hand move of electromagnetic force in figure of electromagnet 26.That is, if electromagnet 26 produces electromagnetic force, right-hand move of sheet metal 32 in figure.Otherwise if electromagnet 26 does not produce electromagnetic force, sheet metal 32 moves by the left of pressure in figure of silicone oil.
Valve rod 28 is fixedlyed connected with valve 30 and sheet metal 32.Valve 30 is right-hand in figure to move and closes oil circuit 44 if right-hand move of sheet metal 32 in figure, valve rod 28 make.Otherwise if sheet metal 32 left in figure moves, valve rod 28 makes valve 30 left in figure move and open oil circuit 44.
Sheet metal 32 and electromagnet 26 are installed in the outside of housing 12, make their operation not be subjected to the influence of silicone oil.
In addition, bearing 18 makes electromagnet 26 always irrelevantly stop with the rotation of rotating shaft 16 between electromagnet 26 and rotating shaft 16.
Simultaneously, it is known to one of ordinary skill in the art that the silicone oil in the space that supplies between end cap 10 and the housing 12 is recovered to technical pattern in the reserve 22, so omit its detailed description.
Operation according to the cooling fan clutch of exemplary embodiment of the present invention hereinafter will be described.
Fig. 3 represents the operational flow diagram according to exemplary embodiment of the present invention, and this flow chart shows the cooling fan clutch operational process.
As shown in Figure 3, in step S210, control unit of engine 100 determines whether ignition switch 120 is closed.
If ignition switch 120 closures, in step S220, control unit of engine 100 determines that whether coolant temperature is more than or equal to setting temperature.
If coolant temperature is lower than setting temperature, in step S240, control unit of engine 100 makes operating switch 110 closures, and electric current is supplied with to operating unit 34.Under this state, electromagnet 26 produces electromagnetic force, and sheet metal 32 is right-hand moving in figure, and valve 30 cuts out oil circuit 44.Therefore, the frictional force between rotor 14 and the housing 12 diminishes, and fan 20 and rotating speed become littler.
If the temperature of freezing mixture is greater than or equal to setting temperature, in step S230, control unit of engine 100 makes operating switch 110 disconnect and cuts off to operating unit 34 electric current supplies.Under this state, electromagnet 26 does not produce electromagnetic force, and sheet metal 32 moves by pressure left in figure of silicone oil, and valve 30 is opened oil circuit 44.Therefore, silicone oil supplies between rotor 14 and the valve body 12, and it is big that the frictional force between rotor 14 and the valve body 12 becomes.Therefore, the rotational speed of fan 20 becomes faster.
Step S220-S240 lasts till that always ignition switch closes.
According to exemplary embodiment of the present invention, control unit of engine is based on the temperature of the freezing mixture of being surveyed by coolant temperature sensor and the operation of control operation unit can improve the operation response to coolant temperature like this.
In addition, because operating unit comprises the electromagnet that produces electromagnetic force according to power stream, can further improve operation response to coolant temperature.
Because improved the operation response to coolant temperature, cooling effect is improved.Therefore, can prevent that motor is destroyed.
Though the present invention is by being illustrated in conjunction with the current exemplary embodiment that is considered to practicality, but need be appreciated that and the invention is not restricted to disclosed specific embodiments, on the contrary, the present invention ought to be contained various corrections and the equivalent arrangements in the spirit and scope that are included in appended claim.
