Abstract
The utility model discloses a fan clutch. One end of a fan hub 2 is connected with a spring piece 3 and is connected with an attracting disk 11 by the support of the spring piece 3; the end of a belt pulley 4 corresponding to the attracting disk 11 is provided with an electromagnetic core 6 covered by a coil 5, and the other end of the belt pulley 4 is respectively provided with a copper ring 7 and an electric brush 10; the electric brush 10 is in contact with the copper ring 7; a conducting wire 12 is connected to the coil 5 and the copper ring 7. The fan hub is attracted by an electromagnetic device to drive fan blades 1 to rotate for the cooling and the heat dispersion of a water tank, the power loss caused by the continuous rotation of the original fan blades with an engine is eliminated, fuel oil is saved by 5% to 8%, and the abrasion of the engine in the state of cooling is reduced.
Description
The utility model relates to automobile component, is specifically related to the fan clutch of Control of Automobile engine water tank cooling usefulness.
Reducing the motor car engine operating temperature is to cool by the circulating water in its body, and circulating water dispels the heat through engine water tank.In order to accelerate the cooling of cistern circulated water, the fan blade that people adopt the belt pulley that is connected on the water pump spindle directly to drive on the fan hub rotates, and lowers the temperature to realize the heat that dispels water tank.This directly driving type linkage structure exists deficiency to be: the one, and motor under the situation that water tank temperature need not be lowered the temperature, drives the power loss nearly 10% that the fan blade rotary work easily increases motor as long as work promptly drives fan blade rotation cooling by belt pulley; The 2nd, be difficult to keep the motor optimum working temperature, optimum working temperature as motor is generally about 80 ℃, if the circulating water in the water tank just begins to cool through the fan blade rotation under cold state, then prolong motor and crossed cool time, quicken the wearing and tearing under the engine cold state, reduced the working life of motor.
The purpose of this utility model is to provide the loss of a kind of minimizing engine power, makes motor realize optimum working temperature as early as possible, reduces the wearing and tearing under the engine cold state, improves the motor electromagnetic fan clutch in working life.
The technical solution of the utility model is achieved in that the belt pulley and the fan hub that mainly are connected on the water pump spindle by rotation constitute, and its improvements are: fan hub one end is connected with spring sheet, and is connected with the adhesive dish by the spring sheet supporting; Be provided with the electromagnetic core that coats coil with the corresponding belt pulley of adhesive dish end; Belt pulley the other end is respectively equipped with copper ring and brush; Brush and copper ring contact; Lead is connected in respectively on the coil and copper ring at belt pulley two end part.
Because belt pulley of the present utility model two ends are provided with calutron, when engine water temperature surpasses a certain numerical value, can control calutron adhesive fan hub easily and drive the fan blade rotation, eliminate original fan and do not stopped to rotate the power loss that causes with motor to water tank heat radiation cooling; After tested, save fuel oil 5-8%; In addition, can make the operating temperature of motor reach the optimum temperature state rapidly, shorten the cool time of crossing of motor, reduce the wearing and tearing under the engine cold state, the working life of having improved motor.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 has the plan view of section for the utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Fig. 1, shown in Figure 2.Belt pulley 4 is fixed on the water pump spindle 9 of water pump 8, and the fan hub 2 that is connected with fan blade 1 links to each other with belt pulley 4 by bearing.On fan hub 2 right-hand member end faces, an end that is respectively equipped with 3 spring sheets 3 is connected in fan hub 2, and the other end binding is supported on adhesive dish 11; In recessed annular groove on adhesive dish 11 corresponding belt pulley 4 end faces, be connected with the electromagnetic core 6 that coats coil 5.In belt pulley 4 the other end counterbores, be fixed with the copper ring 7 of isolating by insulation board; The brush 10 that is installed on the water pump 8 contacts with copper ring 7.Lead 12 is connected in respectively on the coil 5 and copper ring 7 at belt pulley 4 two end part.
Working principle: during the automobile engine starting operation, motor drives belt pulley 4 rotations, at this moment, leaves spacing 13 between adhesive dish 11 both ends of the surface on belt pulley 4 and the fan hub 2, belt pulley 4 can only dally on water pump spindle 9, and the fan blade 1 that can't drive on the fan hub 2 rotates synchronously.When engine water temperature surpasses 80 ℃, warm inductive circuit energising by thermosensitive element control, and conduct in coil 5 through brush 10 and to make electromagnetic core 6 produce magnetic force, electromagnetic core 6 overcomes the elastic force that adhesive dish 11 is subjected to spring sheet 3, with adhesive dish 11 tightly adhesive on the end face of belt pulley 4, this moment, fan hub 2 drive fan blades 1 rotated synchronously with belt pulley 4, and the cooling air of formation is to the circulating water radiating and cooling in the water tank.When water temperature is lower than 80 ℃, warm inductive circuit outage, electromagnetic core 6 magnetic force disappear, and adhesive dish 11 is separated with electromagnetic core 6 rapidly by the elastic force of its spring sheet 3 and is reset to original state (shown in Figure 1), and cooling air disappears.Treat that water temperature rises when surpassing 80 ℃ in the water tank, warm inductive circuit is subjected to thermosensitive element control to repeat above-mentioned action once more.
