Abstract
The utility model relates to a fan clutch device for automobile engines. An electromagnetic coil is arranged between a fan pulley and a fan, and the lower part of the fan pulley is provided with a temperature controlling switch; the upper part of the electromagnetic coil is provided with an electromagnetic sucker, and the lower part is provided with an insulating copper ring; one side of the insulating copper ring is provided with a carbon brush, and one end of the carbon brush is connected with the inner wall of the insulating copper ring; the electromagnetic sucker and a fan assembly are processed into a whole. The temperature-controlling switch is attracted to supply a power supply for the electromagnetic coil to produce a magnetic field, so that the electromagnetic sucker is attracted, and the fan works; inversely, the fan stops working. The automatic control is easy to realize by the electromagnetic sucker, and the operation of automobile engines can be ensured at the optimum temperature. The utility model is suitable for various new and old automobiles to install.
Description
The utility model relates to the controller of automobile engine cooling fan.
Fan is the vitals of car engine cooling system, is installed in the radiator rear usually, and is coaxial with water pump.They are driven by the Vee pulley V speedup by engine crankshaft, and rotating speed is up to more than 4500 rev/mins.Fan and water pump spindle are affixed, as long as start, fan is rotation just, and fan institute wasted work rate accounts for 10% of motor total output.Statistics shows, engine-cooling system has only time of 25% to need fan work, does not particularly need fan work substantially winter, and one to winter, all covers with lagging on the car engine, the contradictory phenomena of cotton dress blowing occurs wearing.For this reason, more existing fan clutches come out, and as magnetic clutch being additional on the former fan, axial dimension must strengthen, and radiator will move forward, performance difficulty.Mechanical clutch also needs hand control except that the big shortcoming of size, can not regulate automatically, and is very inconvenient.
The purpose of this utility model is at deficiency of the prior art, and a kind of of design can be with the fan governor of motor car engine temperature auto-closing or disengagement, thus make engine blower can be according to actual needs start-stop automatically, realize control automatically.
Concrete technological scheme of the present utility model is: be provided with electromagnetic coil between fan pulley and the fan, the fan pulley bottom is provided with a temperature detect switch (TDS), and electromagnetic coil top is provided with electromagnetic chuck, and the bottom is provided with the insulation copper ring; Electromagnetic chuck and fan assembly are one, and fans and electromagnetic chuck are fixedly connected with fixing frame; Be provided with spring and set screw between electromagnetic chuck and the electromagnetic coil, insulation copper ring left side is provided with the carbon brush, and carbon is brushed termination insulation copper ring inwall, a relay termination switch; Electromagnetic coil, carbon brush, temperature detect switch (TDS), relay switch and automobile storage battery constitute the loop.
Accompanying drawing is the utility model structural representation.
Among the figure: 1-fan pulley 2-fan 3-electromagnetic coil 4-electromagnetic chuck 5-insulation copper ring 6-fixing frame 7-spring 8-screw 9-carbon brush 10-temperature detect switch (TDS) 11-relay switch
Describe in detail below in conjunction with accompanying drawing:
The utility model is that a face with fan assembly is processed into electromagnetic chuck 4, between fan pulley 1 and fan assembly, set up electromagnetic coil 3 and insulation copper ring 5, establish carbon brush 9 in the left side of insulation copper ring 5, one termination insulation copper ring, 5 inwalls of carbon brush 9, the other end is succeeded electric switch 11, be provided with temperature detect switch (TDS) 10 in the bottom of fan pulley 1, when the temperature of motor car engine rises to more than 75 ℃, temperature detect switch (TDS) 10 closures, relay switch 11 closures, carbon brush 9 produces magnetic field and makes electromagnetic chuck 4 adhesives to electromagnetic coil 3 power supplies.Fan work.When the temperature of motor car engine drops to below 60 ℃, temperature detect switch (TDS) 10 disconnects, and relay 11 switches disconnect, and electromagnetic coil 3 does not have electricity, and electromagnetic chuck is thrown off, and fan quits work, and plays insulation effect.And so forth.
Electromagnetic chuck of the present utility model is easy to realize automatic control, and fan is only just opened in needs, has obvious energy-saving effect, and can guarantee that motor car engine works under optimum temperature, compact structure need not big change, is suitable for the transformation of existing vehicle.
