Description

Novel automatically controlled silicon oil fan clutch initiative board

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 initiative board.

Background

The driving plate is a main part of the silicon oil fan clutch, rotates along with the driving shaft, is provided with a plurality of labyrinth grooves on two surfaces, and transmits torque by using silicon oil shearing viscous force so as to drive the shell and the fan 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 grooves of the driving plate of the current fan clutch are 12 in number, the depth is 4.5mm, because the fan clutch is large, the required torque force is large, so the number of the labyrinth grooves is large, the relative oil return speed is low, the top end faces of the labyrinth grooves of the driving plate of the current fan clutch are on the same horizontal plane, the depths of the labyrinth grooves are uniform, for the larger fan clutch, the number of the labyrinth grooves is large, the oil return speed is low, the performance of the fan clutch is not ideal enough, and the oil saving effect is poor.

SUMMERY OF THE UTILITY MODEL

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

The utility model provides a novel automatically controlled silicon oil fan clutch driving plate, including clutch driving plate body, be provided with a plurality of maze groove on the clutch driving plate body, the maze groove comprises maze groove degree of depth and maze groove terminal surface, is close to a plurality of clutch driving plate body excircle the maze groove terminal surface becomes low gradually along the direction of interior circle to the excircle, just the maze 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 driving plate body of the clutch are arranged in a gradual change manner.

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 silicon oil fan clutch driving plate changes the labyrinth groove depth and the labyrinth groove end surface of 5 labyrinth grooves close to the excircle of the clutch driving plate body, particularly designs the labyrinth groove end surface of 5 labyrinth grooves close to the excircle of the clutch driving plate body to be gradually reduced, designs the labyrinth groove depth of 5 labyrinth grooves close to the excircle of the clutch driving plate body to be gradually reduced, due to the action of centrifugal force, when the silicon oil fan clutch works, silicon oil is thrown to the direction far away from the center, namely, is thrown to the excircle direction of the clutch driving plate body, the end surface of 5 labyrinth grooves close to the excircle of the clutch driving plate body is gradually reduced, the oil return speed can be accelerated by gradually reducing the depth of the 5 labyrinth grooves, the oil return performance of the fan clutch can be improved by accelerating the oil return speed, the oil saving effect is enhanced, and the heat degree of the silicon oil fan clutch can be relatively reduced quickly, the service life of the fan clutch is prolonged.
