Description

Novel automatically controlled silicon oil fan clutch protecgulum

Technical Field

The utility model relates to an automatically controlled fan clutch technical field of part for the car, in particular to novel automatically controlled silicon oil fan clutch protecgulum.

Background

The front cover is one of the main parts of the silicon oil fan clutch, and a plurality of the front cover and the labyrinth groove of the driving plate jointly complete shearing silicon oil viscous force and transmit torque, so that the shell and the fan are driven to rotate.

The silicone oil fan clutch is used for adjusting the cooling intensity of the engine at any time according to the thermal condition of the engine. In summer, the engine works at low speed and under heavy load, and when the temperature of the cooling liquid is very high, the fan needs to rotate at high speed to increase the cooling air volume and enhance the heat dissipation capacity of the radiator; in winter, when the temperature of the cooling liquid is low, or when the automobile runs at high speed and strong head-on wind blows over the radiator, if the fan continues to rotate at high speed, the power of the engine is consumed, and great noise is generated, and at the moment, the fan needs to rotate at low speed.

The principle of the silicone oil fan clutch is that the temperature of air behind the radiator is utilized, and the fan clutch is automatically controlled to be disengaged and engaged through a temperature sensor. At low temperatures, the silicone oil does not flow, the fan clutch is disengaged, the fan speed is slowed, and essentially idles. When the temperature is high, the viscosity of the silicone oil enables the fan clutch to be combined, so that the fan and the water pump shaft rotate together (rotate at high speed), and the function of adjusting the temperature of the engine is achieved.

The labyrinth groove of present fan clutch protecgulum has 12, and the degree of depth is 4.5 millimeters, because fan clutch is great, the torsion that needs is just big, so this labyrinth groove is more, relative oil return will be slow, and the labyrinth groove top end face of present fan clutch protecgulum all is on a horizontal plane, the labyrinth groove degree of depth is all unanimous, to great fan clutch, the more its oil return speed in labyrinth groove is relatively slow, make fan clutch's performance unsatisfactory, the effect of economizing on fuel is relatively poor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a novel automatically controlled silicon oil fan clutch protecgulum can solve the problem of proposing among the above-mentioned background art.

The utility model provides a novel automatically controlled silicon oil fan clutch protecgulum, including the clutch protecgulum body, be provided with a plurality of labyrinth groove on the clutch protecgulum body, labyrinth groove comprises labyrinth groove degree of depth and labyrinth groove terminal surface, is close to a plurality of clutch protecgulum body excircle labyrinth groove the labyrinth groove terminal surface becomes low gradually along the direction of interior circle to the excircle, just the labyrinth groove degree of depth becomes shallow gradually along the direction of interior circle to the excircle.

Preferably, the total number of the labyrinth grooves is 11, and 5 labyrinth grooves close to the excircle of the clutch front cover body are arranged in a gradual change mode.

Preferably, the depth of 6 non-gradual change labyrinth grooves is 4.5 mm.

Preferably, the gradually changing depth of 5 labyrinth grooves is 4.5mm, 4.0mm, 3.5mm, 3.0mm and 2.5mm in sequence along the direction from the inner circle to the outer circle.

The utility model has the advantages that: the novel electric control silicone oil fan clutch front cover changes the labyrinth groove depth and the labyrinth groove end surface of 5 labyrinth grooves close to the excircle of the clutch front cover body, particularly designs the labyrinth groove end surface of 5 labyrinth grooves close to the excircle of the clutch front cover body to be gradually reduced, designs the labyrinth groove depth of 5 labyrinth grooves close to the excircle of the clutch front cover body to be gradually reduced, because of the action of centrifugal force, when the silicon oil fan clutch works, the silicon oil is thrown away from the center, namely, the end surfaces of 5 labyrinth grooves close to the excircle of the clutch front cover body gradually become lower by throwing towards the excircle direction of the clutch front cover body, the depth of 5 labyrinth grooves is gradually reduced to accelerate the oil return speed, the performance of the fan clutch can be improved and the oil saving effect is enhanced, and the oil return is quick, so that the heat of the silicone oil fan clutch can be relatively reduced, and the service life of the fan clutch is prolonged.

Detailed Description

In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

As shown in fig. 1 and fig. 2, the embodiment of the utility model provides a novel automatically controlled silicon oil fan clutch protecgulum that provides, including clutch protecgulum body 1, be provided with a plurality of labyrinth groove 2 on the clutch protecgulum body 1, labyrinth groove 2 comprises labyrinth groove degree of depth 3 and labyrinth groove terminal surface 4, is close to a plurality of the 1 excircle of clutch protecgulum body labyrinth groove 2 labyrinth groove terminal surface 4 becomes low gradually along the direction of interior circle to the excircle, just labyrinth groove 2 labyrinth groove degree of depth 3 becomes shallow gradually along the direction of interior circle to the excircle.

In this embodiment, the total number of the labyrinth grooves 2 is 11, and the labyrinth grooves 2 are gradually changed and arranged near 5 outer circles of the clutch front cover body 1.

In this embodiment, the depth of each of the 6 non-gradual change labyrinth grooves 2 is 4.5 mm.
