Abstract
The utility model relates to a clutch device for a vehicle engine cooling fan and can be used for automatically controlling the operating state of the fan according to the cooling water temperature of the engine. The utility model can be realized through the following schemes that the volume of a paraffin which is arranged in a seal cavity increases when the cooling water temperature is more than the melting point; through a piston, the paraffin pushes an internal cone body, and therefore, the internal cone body and an external cone boy are closed together. The fan arranged on the external cone body and the internal cone body under the active state rotates together. When the cooling water temperature decreases to the valve which is below the melting point of the paraffin, the paraffin is solidified. Under the function of a return spring, the internal cone body and the external cone body are separated; the fan can do nothing but operate at the very low rotational speed.
Description
The utility model relates to a kind of fan temperature control clutch, particularly a kind of fan temperature control clutch that is used for cooling usefulness on the vehicle motor, and it can control the rotating speed of fan automatically according to the temperature of cooling water.
Because vehicle motor will dispel the heat at work, different with ambient temperature and engine operating condition.The engine power of required heat radiation is also different.Vehicle motor and cooling fan before the utility model are directly installed on the motor.The rotating speed of fan and the power of consumption can not be regulated, and the design of fan is according to designing under peak output, high ambient temperature, in fact 90% time is not need so big cooling air quantity, so both wasted engine power, and made motor can not reach optimum working temperature very soon again.
In recent years, adopted silicone oil temperature control clutch and fluid coupling to improve the performance of fan on some vehicle motor, these two kinds of clutches all are by heat responsive element, and control charges into the amount that has the certain viscosity medium between the master and slave moving part, regulates rotating speed.Check in from patent gazette, also have by other method and regulate rotating speed, routine F16D13/30, application number is 88205603.4 and F01P7/08, application number is 88210971, and the former utilizes temperature-sensitive and the actuator of memory alloy as cooling water, the automatic clutch of control fan and belt pulley.The latter promotes clutch plunger by the wax temp-sensitive apparatus, by the to-and-fro motion of piston, causes the variation and the brake pad clutch of silicone oil pressure in the clutch release slave cylinder, realizes the fan clutch speed governing.
Technology contents of the present utility model is: fan temperature control clutch mainly partly is made up of driving and driven part, temperature-sensitive.Active part directly is connected with motor, and secondary part is connected with fan, and the temperature-sensitive part is made up of paraffin, piston, internal cones, when temperature surpasses melting point of paraffin wax, and melted paraffin wax.Directly promote to be contained in the internal cones of active part, inside and outside cone is closed.Reach the purpose of transmitting torque.When temperature drops to when being lower than melting point of paraffin wax, paraffin solidifies, volume-diminished, and under the effect of return spring, internal cones breaks away from external cone, can not pass on moment of torsion.
Below in conjunction with a description of drawings embodiment of the present utility model.
By flanged plate (1) dynamo belt dish and connecting plate (2) are connected together, bolt (3) is through baffle plate (9), internal cones (5), return spring (4) together, refill external cone (10), be screwed in then on the connecting plate (2), internal cones (5) can be gone up at bolt (3) and slide, piston (7) is housed on the internal cones (5), is full of paraffin (6) therebetween.Seal ring (8) is housed on the piston (7), fan (11) and end cap (12) are housed on the external cone (10).Under the normal temperature state, leave gap A between internal cones (5) and the external cone (10).When engine operation, by flanged plate (1), the feasible part that links together with bolt (3) rotates simultaneously.When coolant water temperature was lower than melting point of paraffin wax, paraffin was in solid-state, because the existence of gap A, external cone (10) only is subjected to the very effect of less friction, thereby fan can only produce very little rotating speed.When coolant water temperature was higher than paraffin melting point, melted paraffin wax, volume became big, make internal cones (5) overcome the power of return spring (4), move right.After gap A eliminated, internal cones (5) was given (10) axial forces of external cone, and internal cones (5), external cone (10) be rotation together just, and fan (11) is and then rotation also.When temperature drops to when being lower than melting point of paraffin wax, the smaller volume of paraffin, return spring (4) promotes internal cones (5) and is moved to the left, and separates with external cone (10), and fan (11) can only be with very little rotation speed operation.Can regulate the size of fan power by bolt (3).
The utility model can be saved the power of motor, makes motor keep optimum working temperature simultaneously.The utility model is simple in structure, is easy to long working life is installed.
Claims (6)
1, a kind of fan temperature control clutch, the fan temperature control clutch especially for vehicle motor cooling usefulness comprises connecting plate (2), bolt (3), baffle plate (9), external cone (10) is characterized in that:
