Each parts of the utility model label in the drawings is as follows:
Friction disk spindle nose locking nut 1, friction disk spindle nose pad 2 connects steel disc 3, friction disk 4, belt pulley bearing jump ring 5, belt pulley bearing 6, belt pulley 7, electromagnet coil 8, electromagnet coil jump ring 9, support 10, cooling fan bearing 11,14, cooling fan axle 12, oil nozzle 13, gland bolt 15, bearing gland 16, cooling fan spindle nose connecting key 17, fans connecting bolt 18, fan spindle nose 19, fans 20, fan shaft headrest sheet 21, fan spindle nose locking nut 22, friction disk spindle nose connecting key 23 connects steel disc rivet 24, friction disk spindle nose 25, fans attaching nut 26, valve 27, connecting rod 30,32, Returnning spring 29, lever 31, operating grip 33, engine water jacket 34, radiator 35, water pump 36, electromagnet coil L, thermostat WJ, (select automobile direct current Wiper motor for use, it carries retarder to drive motor M, cam and auxiliary contact FJ).
As we can see from the figure, the main structure of cooling fan is support 10, fans 20, fan shaft 12, belt pulley 7, friction disk 4 in the utility model.Fan shaft 12 is installed on the support 10 by fan spindle bearing 11,14, and fans 20 is installed on the fan spindle nose 19, is that belt pulley bearing 6 is connected between belt pulley 7 and the fan shaft 12.Friction disk 4 is fixed on the friction disk spindle nose 25 by connecting steel disc 3, connect steel disc 3 and be at least three, along friction disk 4 circumference uniform distributions, and between the friction disk 4, friction disk spindle nose 25 with rivet 24 riveted joints.Friction disk spindle nose 25 is sleeved on fan shaft 12 rear ends, connects with key 23 between the two.Friction disk 4 is a ring, and its card is axial vertical with fan shaft 12; Friction disk 4 cards lean against on the ear end face of belt pulley 7, leave the gap between the two.Electromagnet coil L is installed in the hub of belt pulley 7, and electromagnet coil L is electrically connected with relay J 1, thermostat WJ.Fan pulley is by the motor driven rotary.
Working procedure below in conjunction with Fig. 2,4 explanation cooling fans.The WJ of thermostat shown in the figure is installed in (or other position of constituent) on the motor, makes it experience the water temperature height.When water temperature is lower than 80 ℃, not conducting of thermostat WJ, electromagnet coil L does not have electric current to pass through, this moment is owing to have a very little gap between the ear end face of friction disk 4 and belt pulley 7, friction disk 4 does not contact with belt pulley 7, so belt pulley 7 is with the race of engine, and cooling fan does not rotate.When water temperature rises to 80 ℃, thermostat WJ connects, relay J 1 adhesive, electromagnet coil L energising produces magnetic force, because friction disk 4 connects by being connected steel disc 3 with friction disk spindle nose 25, connects steel disc 3 and has good elasticity, therefore when friction disk 4 when being connected steel disc 3 and being subjected to the attraction of electromagnetic force, they will be close to electromagnet coil L, promptly is close to the end face of belt pulley 7, rotates thereupon.As previously mentioned, friction disk 4, friction disk spindle nose 25, fan shaft 12, fans 20 connect successively, rotate with belt pulley 7 so work as friction disk 4, and fan shaft 12 promptly drives fans and rotates.When water temperature was reduced to below 80 ℃, thermostat WJ disconnected, electromagnet coil L outage, and electromagnetic force disappears, and friction disk 4 breaks away under the elastic force that connects steel disc 3 and the contacting of belt pulley 7 end faces, and recovers the home position, and belt pulley 7 continues to dally, and fan stops operating.
Control procedure to big or small pump circulation path b, a is as follows:
When the motor car engine temperature is lower than 80 when spending, auxiliary contact FJ makes motor M run to initial position, be that motor M institute strap cam (or crank) makes progress, connecting rod 30 drives lever 31, connecting rod 32, operating grip 33 motions under Returnning spring 29 effects, make switch 27 be in closed condition, cut off the major cycle path b of cooling liquid, only have short circle path a to connect, to reduce the heat radiation of motor.When water temperature is higher than 80 when spending, thermostat WJ closure, relay J 1 adhesive, the control coil of the changeover contact J1-2 of power supply by relay J 1, relay J 2 when capacitor C1 charge, just disconnection after the relay J 2 moment adhesive, capacitor C2 is charged to supply voltage, the output end signal conversion of 555 time base circuit chips, relay J 3 adhesives, the current supply circuit of the J3-1 contacting motor M of relay J 3, motor rotates; Simultaneously, capacitor C2 discharges by resistance R 2, when capacitor C2 discharges into 1/3rd supply voltages, and relay J 3 dead electricity, motor stall.Cam driven connecting rod 30 motions on the motor output shaft are opened valve 27, and cooling liquid inflow radiator 35 dispels the heat, and reaches the purpose of major cycle heat radiation; When the water temperature of motor rejects heat to 80 degree when following, thermostat WJ disconnects, relay J 1 outage, power supply makes motor rotation to initial position by conversion normally-closed contact, the auxiliary contact FJ of relay J 1, and promptly cam makes progress, and connecting rod 30 is in free state, Returnning spring 29 is closed valve 27, cut off the major cycle path b of engine coolant, reduce the heat radiation of motor, temperature is remained at about 80 degree.
The numerical value of regulating resistance R, capacitor C is the length of can regulate delay time.
Valve in the utility model adopts ceramic core stop valve or gate valve, and its operating grip also can adopt other relay, solenoid valve or electronic switch control.
