[Prior Art] In the technical field known as the coolant for cooling in a vehicle radiator, it is necessary to force air to the outside of the radiator in order to dissipate heat from the liquid to the boundary more quickly. The fan and the fan on the drive shaft rotate to obtain the forced air flow of Shihai. The fan contains ancient evil ^ "Red skin reading" Its belt activated by the drive shaft receives power. It is also known that the fan must be made The second temperature can be turned only when a certain predetermined water temperature is reached. The thermostat detects the thermostat to activate the electromagnetic clutch, and the turning off of the electromagnetic clutch makes the fan start to rotate. Production Γ! Specifically, one is needed for the vehicle The fan must be able to rotate in the following situations:-Cooling at a rate lower than the drive shaft in low ambient temperature conditions; Auto 2 External high temperature or at the same speed as the drive shaft in severe use conditions that cause the engine to overheat ;-,: In a special low temperature that does not require further cooling or even harmful, with zero, "moving, in other words, the fan does not rotate at all and remains in an idle state. Stuck on the transmission shaft dimension: In special climatic conditions, sometimes the fan also powers the shaft to rotate at a speed of β β "" in 200305518, in an attempt to achieve these performance characteristics, it is used near the permanent magnet Based on the parasitic current generated by the rotating conductive element, a hybrid type of electromagnetically operated friction clutch and drive light coupling has been developed. Although the above functions are completed, these known devices do not allow the fan to be gradually driven because There is a functional limitation that the number of magnets required cannot be reduced in order to achieve the desired performance. = The technical problem caused is to provide a coolant for transmitting the rotational force to the wind to cool the vehicle. Single-starter: Started, and allows the fan to rotate with multiple rotations. This relay is controlled and adjusted according to the actual cooling requirements of the engine, so it is also possible to keep the fan stationary in the case of very low temperature Further in the field of this problem-it is required that the device should be controlled by direct sensing of the temperature of the agent, It is well known that the choice of the rain pattern should be small, and it should have small radial and axial dimensions. [Summary of the Invention] According to the present invention, these technical problems are solved by a device that transmits power to a fan using a coolant. Zhong t two mechanisms to earn the device, a rotating mechanism for generating power to send power, at least one for connecting ^ Yu Chuan ::: rotor, and at least one can generate-adjustable magnetic /, The device 8 200305518 for coupling between the driving rotor and the power transmission mechanism is a type including magnetic powder. Further details can be obtained from the following description of a non-limiting example of an embodiment of the present invention, and reference is made to related drawings. [Implementation Mode] As shown in FIG. 1, the device for transmitting power to the cooling fan 1 includes a power generating component 10 composed of a support 11 extending axially and coupled to a rotating shaft 12. The rotating shaft 12 may be a water pump shaft, for example. Therefore, it rotates together with it. A power-transmitting rotating component 20 is coupled to the rotating support u through a damping element 13 placed on the two of it and the rotating support η, the aforementioned component 202: Γ What it says: Γ A bell-shaped element 21 formed by a radial member 21a and an axially extending ring-shaped member 21 b. The cooling. Fin 22 is formed on the outer surface of the bell-shaped element 21. Extending the interior of 21b, the bell-shaped element 2 can be made of a ring 23 made of virgin material, the purpose of which will be made clear as follows. Axial load mentioned above: segment type) A bearing 50 is also mounted on the rotating support 11, front Fan! Driven by the transmission mechanism 20, the fan 1 and the driving rotor 30 to 40 (for starting, controlling, and adjusting the wind coupling light coupling) (for starting, controlling, and adjusting in more detail, the bearing ring w, the middle Second ring = the first and second middle ring 52 ::: Γ ring 53 inserted and locked on the support η; the outer ring 53 carries a fixed electric rotor 30, and the other side is stretched and the square There is the aforementioned magnetic assembly 40. The drive rotor 30 is essentially formed by a shape 31 having a flange 31 extending axially, and a seat 33 of the flange 31 41. ⑬ The edge 32 is used to place an electromagnet. The annular edge 32 is formed by a magnetically conductive material and the edge 32 is magnetically conductive in the axial direction. The guided magnetically insulated element 32a is axially divided as illustrated in Fig. 1. In addition to being supported by the outer ring 53 of the sleeve 50 of the car seat 50, the electromagnet 41 of the module 40 is also fixed to the fixing member by the security link 42. 43 is in the flange 31, and is-a suitable radial air gap 60b appears in the bismuth cry -... ^ to create a ring edge of σ 32, the ring 23 of the power transmission assembly 20 pi ^ ^ Between the m, the air gap _ is formed by a pair of arrangement = sub 3 " mesh opposite sides to form the lip part of the joint light coupler ... Dense: bottom and one with magnetic powder 6. " Storage ". Communicating, its operating principle of the device is as follows: In normal operating conditions, the rotating shaft 12 continues to rotate the support n, and the surface is closed. Block 11 rotates together: In the situation shown in Figure 1, it is also envisaged that the control unit, the second, and the second excitation electromagnet 41 shown in Figure 1 are used to generate a magnetic field. No, it is closed by the annular edge 32 of the coupler and the ring 23 of the bell-shaped element 21; the powder 60a is then led back to the air gap 6 between the edge 32 and the ring 23 and magnetized; 200305518-the magnetic powder 60a causes the edge 32 and The relative engagement of the ring 23, and thus the flange 3 starts to rotate. The flange 31 starts to rotate by the fan "mesh" of the bearing 50; I. Wind

This will cause the magnetic powder 6Ga to be larger / smaller magnetization and strengthen / weaken the edge 32 and the ring 23 Radial relative engagement, which results in a full engagement (transmits power directly from the shaft 12 to the fan 1 rotating at the same number of rotations as the shaft 12) or the edge 32 slides opposite the ring 23 (in other words, the number of rotations of the fan 1 is greater than the shaft The number of revolutions of 12 is small); By adjusting the power supply of the electromagnet, the number of revolutions of fan 1 can be adjusted according to the actual operation requirements, which depends on the conditions outside the vehicle or the special conditions regarding use (driving on or Finally, turning off the power supply of the electromagnet caused the demagnetization of the magnetic powder, and thus the engagement between the edge 32 and the ring 23 was interrupted, so the fan ’s turning action stopped. In the cycle described above, the lip The shape seal 61 works as follows:-Until the flange 31 reaches a certain speed, the lip 61 a is elastically pushed against the flange to perform its sealing effect with respect to the magnetic powder 60a; once the magnetic powder 60a is magnetized and Therefore, by the magnetic flux Attracted and retained in the air gap 6Ob, and after the flange 31 reaches a certain speed, the centrifugal force pushes the lip 61 a so that it leaves the flange 31, thus avoiding friction caused by frictional contact;-conversely, when the speed decreases In hours, the lip 61a elastically retracts into contact with the flange 31, and at this time the magnetic powders 60a are losing their magnetic force and sealing it again 11 200305518. Figure 2 shows a second example of an embodiment of a device according to the invention It is envisaged in this situation that the magnetic field generating device 140 includes an electromagnet 41 and a permanent magnet 145 sufficient to generate a magnetic field of a fully magnetized magnetic powder 60a, so as to create a full engagement between the edge 32 and the ring 23 and keep the fan 1 continuous Turning. Exciting the electromagnet 41 causes the generation of a magnetic counter-field that tends to oppose the field of the permanent magnet 145 and cause the edge 32 to slide relative to the ring 23 'to allow the fan 1 to reduce the speed. By fully energizing the electro-magnet 41 The field of the permanent magnet 145 is completely neutralized, causing the fan 1 to stop. Also in this example, the three operating conditions envisaged and The adjustment of the rotation of the fan 1 has the further advantage that in the case of the interruption of the current power supply, the entire operation of the fan can still be guaranteed by the magnetic field generated by the permanent magnet 145. Figure 2 shows a further example of an embodiment of the device — In this example, the support 111 is fixed to the base Ilia of the engine, and the hunting gear is powered by a pulley 112 connected to the driving wheel of the crankshaft by a belt 112a. This driving gear can also be formed to be enlarged relative to the crankshaft. The rotation of the fan is transmitted so that when the device is operating in the direct drive mode, one revolution of the crankshaft is transmitted to the fan. The shape member 21 is therefore mounted on the bearing 113, and the outer ring of the bearing 3 also carries the pulley 112. . Although it is not illustrated here, it is also conceived that the support ⑴ can be formed by a coaxial extension of 12 200305518 engine crankshafts (dotted line), even if it is accompanied by the generation of fan power—one can be ignored, and it is therefore rotated in the 113 condition. of. The fourth example of the embodiment of the device should be shown in this example. In this case, the fan 1 can generate a higher speed than the power generating shaft 12. / In this case, the support n is a rotating platform separated from the wind, and is adapted to be inserted into the bearing of the support u. The flange 321 has an axial extension 321a 'which supports the bearing 5. Inside and a flat front element 336, on the front element — the star gear system 3 5 0 Bai Qian Qian Tu Tu q ς 1 is made of: the star material 35 and its planet wheels 352 are transported separately The teeth of 3 5 3 are latched on the bell-shaped element 353a on the outer ring 53 of the bearing 50 and drives the fan 1; i is set on # 354 (刼 of the planetary system) on the middle ring 52 of the bearing 5G, in In this case, the intermediate ring 52 of the bearing 50 is also coupled to the fixed assembly of the magnet 41. In this structure, the utility system of the planetary gear train 350 allows relative movement: increase the rotation speed of the fan 1 for generating the rotation speed of the rotating shaft 12, so that the forced airflow can be increased, or the fan 1 can be reduced for generating the same flow. The size and therefore reduce the torque required for starting. With regard to the other parts, the operation of the device is still similar to that described with reference to Figure 1 (without permanent magnets) or Figure 2 (with permanent magnets). Finally, FIG. 5 shows an embodiment in which the electromagnet 41 is positioned radially outward with respect to the coupler 30. 13 200305518 It is obvious to a person familiar with this technology that since the operation of the device is completely similar to the other examples already described, it will not be repeated here. It must be noted here that in all the examples of the described embodiment, the electromagnet is a static type, in other words, it is immovable with respect to the rotating part. Although a configuration of a rotating electromagnet can also be envisaged, because The use of current commutators and associated rotating contact brushes has all the problems of wear, sparks, and the like, and is less preferred.
