Abstract
The utility model discloses a temperature control electromagnetic fan clutch device for the water pump of an engine, comprising a belt pulley, a water pump rotary shaft, an electromagnetic coil connected with a temperature-controlling switch, an attract dish and a fan base; the improvement is that the attracting dish and the electromagnetic coil are jointly arranged in the chamber of the belt pulley; the inner bore of the water pump rotary shaft is provided with a draw rod having a return spring; the overhanging end of the draw rod is provided with a pressure dish whose the other end is connected with the attracting dish; the end surface of the pressure dish relative to the fan base is provided with a concave section and a convex section or a friction material layer which enlarge the friction. The temperature control electromagnetic fan clutch device for the water pump of an engine is used for the circulating water cooling system in the engine; when the water temperature exceeds the set temperature, the device causes the fan to automatically rotate to make the cooling and the heat radiation on the circulating water; The temperature control electromagnetic fan clutch device for the water pump of an engine has the obvious advantages such as small volume, low cost, high reliability and reasonable temperature control.
Description
Technical field
The utility model relates to a kind of temperature control electromagnetic fan, especially engaging and disengaging gear of temperature control electromagnetic fan that is used with engine cooling water pump.
Background technique
Motor needs constantly to cool off in the course of the work, generally make circulating water take away heat by water pump, when engine temperature too high, when the water pump cooling is not enough to effectively lower the temperature, further cool off by the temperature control electromagnetic fan that is used again, so that engine operating temperature remains on the optimum state.The rotation of control fan with stop to be achieved by the engaging and disengaging gear that is contained in the water pump rotating shaft, this engaging and disengaging gear comprise temperature detect switch (TDS), electromagnetic coil, adhesive dish and with the critical components such as bindiny mechanism of fan base.Chinese patent ZL99246758.6 discloses the technological scheme of auto pump temperature control electromagnetic fan clutch assembly, wherein electromagnetic coil and adhesive dish place the both sides of belt pulley respectively, be that electromagnetic coil is at the belt pulley inner chamber, the adhesive dish is in the belt pulley outside, and the adhesive dish links to each other with fan base by spring sheet.This structure, owing to be separated with the belt pulley disc between adhesive dish and the electromagnetic coil, strengthened spacing between the two on the one hand, the metal of belt pulley disc intercepts in addition, electromagnetic attraction is greatly reduced, like this, for guaranteeing that enough suction is arranged, run well with drive fan, coil certainly will will be strengthened, both increased cost, strengthened volume again, and made the structural configuration of belt pulley and pump shell more difficult; On the other hand, the spring sheet that connects adhesive dish and fan base will play transmitting torque and the effect that resets, good strength and stiffness should be arranged, good elasticity is arranged again, performance be cannot say for sure to cause the increase of electromagnetism adhesive resistance and winding volume, poor reliability by card, easily go wrong, strengthened the manufacturing maintenance cost.In addition, in the above scheme, temperature detect switch (TDS) is connected on the pump shell, and is not too reasonable, because the temperature of pump shell can only reflect the engine heat load size indirectly, and engine outlet water temperature could truly directly reflect the motor heating degree.
The model utility content
The technical problems to be solved in the utility model provides a kind of compact structure, volume is little, cost is low, reliability is high engine water pump temperature-controlled electromagnetic fan engaging and disengaging gear, and this device also can further improve the rationality of temperature control, strengthens using effect.
The technical solution of the utility model is: engine water pump temperature-controlled electromagnetic fan engaging and disengaging gear, comprise belt pulley, water pump rotating shaft, the electromagnetic coil that links to each other with temperature detect switch (TDS), adhesive dish, fan base, improvements are inner chambers that adhesive dish and electromagnetic coil place belt pulley jointly, be provided with the pull bar of band Returnning spring in the water pump rotating shaft endoporus, the overhanging end of pull bar is provided with platen, the other end of pull bar is connected with the adhesive dish, and the clutch distance of platen and fan base is less than the adhesive distance of adhesive dish and electromagnetic coil end face.
In the such scheme, pull bar and adhesive dish connect together by pulling pin, and pull pin and pass axial waist hole in the water pump rotating shaft; Returnning spring is located between pull bar end face and the water pump rotating shaft endoporus cecum; The opposing end surface of platen and/or fan base has the concave, convex part, also can be provided with friction material layer.
Further scheme is that described temperature detect switch (TDS) is installed in motor water outlet position.
Adopt above technological scheme, because adhesive dish and electromagnetic coil place the same side of belt pulley disc jointly, middle without hindrance every, the adhesive distance is little, electromagnetic attraction is big, and coil can be done lessly like this, thereby reduces the volume of whole device, reduce cost, be convenient to the structural configuration of belt pulley and pump shell.The structure of pull bar, platen compresses reliably, resets flexibly, can guarantee that fan runs well, and improves reliability, and makes easily, and is easy to maintenance.In addition, temperature detect switch (TDS) is installed in motor water outlet position, can more directly reflect the heating degree of motor, and the control temperature is rationally reliable, and using effect is good.Certainly temperature detect switch (TDS) also can be directly installed on the pump shell.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is an A--A place sectional drawing among Fig. 1.
Embodiment
As figure, adhesive dish 5 and electromagnetic coil 6 place the inner chamber of belt pulley 7 jointly, are provided with pull bar 3 in water pump rotating shaft 8 endoporus, between pull bar end face and the water pump rotating shaft endoporus cecum Returnning spring 9 are arranged.The overhanging end of pull bar is provided with platen 1, and the other end is connected with the adhesive dish by finger 4, and finger passes the axial waist hole in the water pump rotating shaft, welds with the adhesive dish.The clutch distance of platen and fan base 2 is less than the adhesive distance of adhesive dish and electromagnetic coil end face, and it is reliable to guarantee that platen and fan base compress when closed.The temperature detect switch (TDS) that links to each other with electromagnetic coil is arranged on motor water outlet position.During work, motor drives belt pulley and water pump rotating shaft rotation, and in-engine water is circulated, adhesive this moment dish, pull bar and platen synchronous idle.When the water temperature in the engine block surpasses set point of temperature, the temperature detect switch (TDS) adhesive, the electromagnetic coil energising produces magnetic field, under magnetic force, the adhesive dish is by adhesive, and drive pull bar, platen move axially, and platen is pressed on the fan base, thereby fan is rotated synchronously, to the further radiating and cooling of the circulating water in the water tank; When water temperature was lower than set point of temperature, temperature detect switch (TDS) disconnected, coil blackout, and magnetic force disappears, and pull bar resets under spring action, and platen unclamps, and fan stops operating.
