Embodiment
Below in conjunction with accompanying drawing embodiment the utility model is related to and to describe in further detail.
To shown in Figure 9, engine water pump temperature-controlled fan clutch device of the present utility model comprises electromagnetic coil 2, adhesive dish 6 and spring sheet 7 that fan fixed base 4, belt pulley 3, water pump rotating shaft 5 link to each other with temperature detect switch (TDS) 8 as Fig. 1.The center hole of belt pulley 3 and water pump rotating shaft 5 are fixed with each other for interference fit, and fan fixed base 4 is fixed with each other with interference fit by the axle journal 31 of bearing 41 internal diameters and belt pulley 3, sees Fig. 1 and shown in Figure 4.And electromagnetic coil 2 is fixed on the water pump cover 1, and the middle and lower part of belt pulley 3 is for being placed on the electromagnetic coil 2, see Fig. 1 and shown in Figure 4, and fan fixed base 4 is positioned at belt pulley 3 tops, and adhesive dish 6 is gone here and there in the water pump rotating shaft 5 between fan fixed base 4 and the belt pulley 3 for cover.Shown in the following and adhesive dish 6 of spring sheet 7 one ends fix, see Fig. 5 and shown in Figure 8, and the top and fan fixed base 4 of spring sheet 7 the other ends fixes, and the upwards elastic force of spring sheet 7 greater than the gravity of adhesive dish 6 less than the magnetic force of electromagnetic coil 2.Be positioned at electromagnetic coil 2 directly on the belt pulley 3 of position, have the through hole 32 that can strengthen electromagnetic coil 2 suction, see Fig. 3, Fig. 7 and and shown in Figure 9, this through hole 32 is distributed on two circles on the belt pulley 3 for even compartment of terrain, sees shown in Figure 3.On the bottom surface of adhesive dish 6, have two annular grooves 62 that can hold wearing and tearing iron filings powder, and can alleviate adhesive dish 6 weight and can increase on the same circle of being positioned at of magnetic field one group perforation 61 also having on the adhesive dish 6, this perforation 61 is three, and be distributed in equably on the same circumferential surface, see shown in Figure 2.Described spring sheet 7 is three, and it is for to be distributed on the card of adhesive dish 6 equably, sees shown in Figure 5.Described temperature detect switch (TDS) 8 is seen shown in Figure 6 for being installed on the water inlet position of water pump cover 1.
Working principle of the present utility model is as follows:
Motor drives belt pulley 3 through v belt and turns round when work, drives water pump vanes 11 and the rotation of water seal assembly 10 rotating rings through shaft connecting bearing 12 again, and the interior water of cooling water tank this moment enters in the engine-cooling system, carries out cool cycles.Because of adhesive dish 6 is fixed on the fan fixed base 4, and fan fixed base 4 adopts rolling bearing 41 to connect, and belt pulley 3 mating faces are gapped, and this moment, adhesive dish 6 and fan fixed base 4 parts were not worked.When engine coolant temperature progressively raises, during greater than engine operating temperature, be contained in temperature detect switch (TDS) 8 actions at water pump cover 1 water intake position, connect electromagnetic coil 2 parts, electromagnetic coil 2 parts energising back produces magnetic field, under magnetic force, electromagnetic coil 2 parts magnetic force are greater than spring sheet 7 elastic force, adhesive dish 6 closely is pull-in on the mating face of belt pulley 3, drive fan fixed base 4 by spring sheet 7, thereby make the plastic cooling fan rotation that is contained on the fan fixed base 4, the cooling water in the cooling water tank makes the water temperature in the cooling system descend through the cooling of plastic cooling fan gradually at this moment.When being reduced to engine operating temperature under the water temperature, temperature detect switch (TDS) 8 actions, cutoff solenoid 2 parts, electromagnetic coil 2 parts dead electricity, magnetic field disappears, and adhesive dish 6 passes through spring sheet 7 elastic reset reset conditions,, plastic cooling fan is stopped the rotation.When engine-cooling system temperature during greater than engine operating temperature, the temperature detect switch (TDS) 8 that is contained in water pump body water intake position just can repeat action described above, realize cooling system temperature control automation, thereby having reached motor works under the operating temperature state that the best is set, reduced the power consumpiton of motor, prolong the working life of motor, saved the energy.
