Description

차량용 팬 클러치 구조Car Fan Clutch Structure

본 발명은 차량용 팬 클러치(FAN Clutch)에 관한 것으로, 라디에이터의 수온에 따라 팬 클러치의 작동을 정확하게 수행할 수 있도록 하여 엔진의 과냉이나 팬의 소음을 적게 하는데 적합하도록 하는 것이다.The present invention relates to a vehicle fan clutch (FAN Clutch), to be able to perform the operation of the fan clutch accurately according to the water temperature of the radiator to be suitable for reducing the engine cooling or fan noise.

잘 알려진 바와 같이, 팬 클러치는 자동팬이라고도 불리우며 팬의 회전을 자동적으로 조절하여 팬의 구동에 소비되는 동력의 손실을 될 수 있는대로 적게하고, 기관의 과냉이나 팬의 소음을 적게하기 위한 장치로서, 팬 클러치에는 유체커플링식, 팬 클러치식, 전기식 등이 있다.As is well known, a fan clutch is also called an auto fan and is a device for automatically adjusting the rotation of the fan to reduce the loss of power consumed to drive the fan as much as possible, and to reduce the engine overcooling and the fan noise. The fan clutch may be a fluid coupling, a fan clutch, or an electric.

상기에 있어서, 팬 클러치식은 제1도에 도시한 바와 같이 라디에이터(20)를 통과하는 공기의 온도를 바이메탈 서머스탯(21)에 의하여 감지하여 팬(22)의 회전속도를 자동변속 시키도록 하는 구성을 가진다.In the above, the fan clutch type is configured to detect the temperature of the air passing through the radiator 20 by the bimetal thermostat 21 as shown in FIG. 1 to automatically change the rotational speed of the fan 22. Has

이와 같은 종래 구성을 가진 팬 클러치는 라디에이터(20)내에 순환되는 물의 온도에 의한 공기의 온도를 이용한 것으로, 공기가 라디에이터(20)를 통과하여 바이메탈 서머스탯(21)에 닿아지는 시간이 있기 때문에 라디에이터(20)의 온도를 정확히 감지할 수 없어 클러치 콘트롤의 정확성이 저하되고, 특히, 종래의 팬 클러치는 바이메탈 서머스탯(21) 작동시 슬라이드 밸브를 작동시켜 오일을 케이스내로 공급 또는 차단케하는 유체 클러치식이므로 팬구동에 따른 동력 손실이 증대되는 문제점을 가지고 있다.The fan clutch having such a conventional configuration uses the temperature of the air by the temperature of the water circulated in the radiator 20, and since the air reaches the bimetal thermostat 21 through the radiator 20, the radiator The accuracy of clutch control is lowered because the temperature of 20 can not be accurately sensed. In particular, the conventional fan clutch operates a slide valve when the bimetal thermostat 21 is operated to supply or shut off oil into the case. Since it is an equation, there is a problem in that power loss due to fan driving is increased.

본 발명은 상기 종래의 팬 클러치가 가지는 문제점을 해소하기 위하여 창출한 것으로, 수온에 따라 클러치의 작동을 정확히 동작시켜 엔진효율을 증대시키도록 함을 목적으로 한다.The present invention was created to solve the problems of the conventional fan clutch, and aims to increase the engine efficiency by accurately operating the clutch according to the water temperature.

상기한 과제를 달성하기 위한 본 발명은 라디에이터의 수온을 검지하기 위한 수온센서와, 상기 라디에이터에 고정시킨 솔레노이드 결합 브라켓에 설치한 솔레노이드와, 상기 수온센서에서 감지된 수온에 따라 솔레노이드를 구동시키는 ECU와, 상기 솔레노이드 전방에 위치한 팬 클러치 하우징의 내부에 설치되며, 일측은 솔레노이드의 전방에 위치하고 타측은 팬 클러치 플랜지의 중심에 형성된 유동홈에 유동가능하게 압입되는 회전축과, 상기 회전축을 중심축으로 하여 고정되며 회전축의 유동에 따라 연동되어 팬을 구동시키는 마찰 클러치부로 구성하여 수온센서에서 감지된 수온에 의해 상기 솔레노이드를 온/오프케 함으로서 마찰 클러치부를 작동토록 함을 특징으로 한다.The present invention for achieving the above object is a water temperature sensor for detecting the water temperature of the radiator, a solenoid installed on the solenoid coupling bracket fixed to the radiator, and an ECU for driving the solenoid according to the water temperature detected by the water temperature sensor Is installed inside the fan clutch housing located in front of the solenoid, one side is located in front of the solenoid and the other side is a rotary shaft that is fluidly press-fitted in the flow groove formed in the center of the fan clutch flange, and fixed to the rotation axis as the central axis It is characterized in that the friction clutch unit is interlocked according to the flow of the rotating shaft to drive the fan to operate the friction clutch unit by turning on / off the solenoid by the water temperature sensed by the water temperature sensor.

제2도는 본 발명인 팬 클러치의 구성도이고, 제3도는 본 발명의 작동상태를 보인 도면이다.2 is a configuration diagram of the fan clutch according to the present invention, and FIG. 3 is a view showing an operating state of the present invention.

라디에이터(1)에는 수온센서(2)를 설치하고, 상기 라디에이터(1)에 솔레노이드(3)를 고정설치하기 위한 솔레노이드 결합 브라켓(4)을 고정시켜 상기 솔레노이드(3)를 고정케하며, 상기 수온센서(2)의 신호는 ECU(5)를 통해 솔레노이드(3)의 코일을 제어하도록 구성한다.A water temperature sensor 2 is installed in the radiator 1 and the solenoid coupling bracket 4 for fixing the solenoid 3 to the radiator 1 is fixed to fix the solenoid 3 to the water temperature. The signal of the sensor 2 is configured to control the coil of the solenoid 3 via the ECU 5.

그리고, 상기 솔레노이드(3)의 작동간(3A)전방에는 팬(6)과 결합된 팬 클러치 하우징(7)의 회전축(8)을 위치케하되, 상기 회전축(8)의 일측을 팬 클러치 플랜지(13)의 중심축에 형성된 유동홈(13a)에 유동가능하게 압입하여 회전축(8)이 회전함은 물론 솔레노이드(3)의 작동간(3A) 작동에 의해 좌,우로 이동하게 한다.In addition, the rotation shaft 8 of the fan clutch housing 7 coupled to the fan 6 is positioned in front of the operation 3A between the solenoids 3, and one side of the rotation shaft 8 is a fan clutch flange ( The rotary shaft 8 is rotatably pushed into the flow groove 13a formed in the central axis of 13 to allow the solenoid 3 to move left and right as well as by operating 3A between the operations of the solenoid 3.

상기 회전축(8)내의 중심부 외주면에는 마찰 클러치부(9)가 설치되는데, 상기 마찰 클러치부(9)는 회전축(8)의 중심점에 일정각도 회전가능하게 설치한 클러치 작동바(10)와, 상기 클러치 작동바(10) 각각의 내면에 리턴 스프링(11)으로 탄설시킨 마찰 클러치판(12)으로 구성하되, 상기 마찰 클러치판(12)의 일측 중심부에 일정크기의 홈(12a)을 형성하여 회전축(8)의 좌,우 방향 유동시 작동바(10)의 내측 일부분이 걸리도록 하였다.A friction clutch unit 9 is installed on an outer circumferential surface of the center of the rotation shaft 8, and the friction clutch unit 9 includes a clutch operation bar 10 rotatably installed at a center point of the rotation shaft 8, and the Consists of a friction clutch plate 12, which is loaded with a return spring 11 on the inner surface of each of the clutch operation bar 10, a groove 12a of a predetermined size is formed in one center of the friction clutch plate 12 to rotate the shaft The inner part of the operation bar 10 is caught by the left and right flows of (8).

즉, 상기 회전축(8)이 우측으로 이동하면, 클러치 작동바(10)의 중심부가 홈(12a)에 걸리면서 클러치 작동바(10)가 좌측으로 회전하여 마찰 클러치판(12)을 밀어주므로서, 마찰 클러치판(12)이 스프링(11)의 탄성을 이기고 양측으로 벌어지면서 팬 클러치 하우징(7)의 내면에 밀착되어 팬(6)이 회전하게 되는 것이다.That is, when the rotation shaft 8 moves to the right, while the center of the clutch operating bar 10 is caught in the groove 12a, the clutch operating bar 10 rotates to the left to push the friction clutch plate 12, The friction clutch plate 12 extends to both sides of the spring 11 to overcome the elasticity of the spring 11, so that the friction clutch plate 12 is in close contact with the inner surface of the fan clutch housing 7 so that the fan 6 rotates.

도면중 14는 풀리, 15는 트러스트 베어링이다.14 is a pulley and 15 is a thrust bearing.

이와 같은 본 발명은 라디에이터(1)를 통과하는 수온이 높아지게 되면, 수온센서(2)에서 이를 감지하여 ECU(5)를 통해 솔레노이드(3)의 코일을 여자시켜 작동간(3A)을 작동하도록 제어시킨다.In the present invention as described above, when the water temperature passing through the radiator 1 is increased, the water temperature sensor 2 detects it and controls the coil 3 of the solenoid 3 to operate the operating period 3A through the ECU 5. Let's do it.

그러면, 상기 솔레노이드(3)의 작동간(3A)이 회전축(8)을 도면중 우측방향으로 밀게 되어 클러치 작동바(10)도 이동하게 되고, 클러치 작동바(10)가 우측으로 이동함에 따라 클러치 작동바(10)의 중심부가 홈(12a)에 걸리면서 클러치 작동바(10)가 좌측으로 회전하게 되며, 결국에는 클러치 작동바(10)의 외측이 좌측의 마찰 클러치판(12)에 접하게 된다.Then, the operation period 3A of the solenoid 3 pushes the rotation shaft 8 in the right direction in the drawing to move the clutch operation bar 10, and the clutch operation bar 10 moves to the right to clutch the clutch. As the central portion of the operating bar 10 is caught by the groove 12a, the clutch operating bar 10 rotates to the left, and eventually the outer side of the clutch operating bar 10 comes into contact with the friction clutch plate 12 on the left side.

이와같은 상태에서, 회전축(8)이 우측으로 더 이동하면, 우측의 마찰 클러치판(12)은 클러치 작동바(10)의 중심부에 닿은 상태로 우측으로 밀리게 되고, 좌측의 마찰 클러치판(12)은 클러치 작동바(10)의 외측이 닿은 상태로 좌측으로 밀리게 되어, 결국에는 제3도와 같이 마찰 클러치판(12)이 팬 클러치 하우징(7)의 내면에 밀착되는 것이다.In this state, when the rotation shaft 8 further moves to the right side, the friction clutch plate 12 on the right side is pushed to the right in contact with the center of the clutch operation bar 10, and the friction clutch plate 12 on the left side is carried out. ) Is pushed to the left in contact with the outside of the clutch operation bar 10, and eventually the friction clutch plate 12 is in close contact with the inner surface of the fan clutch housing 7 as shown in FIG.

제3도와 같이 마찰 클러치판(12)이 팬 클러치 하우징(7)의 내면에 밀착되면, 회전축(8)의 회전력이 전달되어 팬(6)이 회전하게 된다.When the friction clutch plate 12 is in close contact with the inner surface of the fan clutch housing 7 as shown in FIG. 3, the rotational force of the rotation shaft 8 is transmitted to rotate the fan 6.

상기 설명과 같이 팬(6)일 일정시간 동작하여 라디에이터(1)의 수온이 설정온도 이하로 내려가면 솔레노이드(3)가 원위치됨과 동시에 이동되었던 회전축(8)도 원위치되어 마찰 클러치부(9)의 마찰력이 해제되므로 팬(6)의 회전은 정지하게 되는 것이다.As described above, when the water temperature of the radiator 1 falls below the set temperature by operating the fan 6 for a predetermined time, the solenoid 3 is returned to its original position and the rotary shaft 8, which has been moved at the same time, returns to the original position of the friction clutch unit 9. Since the frictional force is released, the rotation of the fan 6 is stopped.

이와 같이 본 발명은 종래 유체 클러치식에서 오일 공급 및 차단을 위한 슬라이드 밸브 작동에 따른 팬구동 동력손실과, 바이메탈 서머스탯 작동을 위한 전력 손실없이 마찰 클러치부를 작동시켜 팬(6)의 구동을 수행하게 하는 것으로, 팬구동 동력 손실을 저감할 수 있게 되고, 라디에이터(1)의 수온을 수온센서(2)에 의해 검지하여 ECU(5)에 의해 솔레노이드(3)를 온/오프케 함으로써 더욱 정확한 팬구동 콘트롤을 수행할 수 있게 되는 것이다.As described above, the present invention allows the fan 6 to be driven by operating the friction clutch without loss of fan driving power and power loss for the operation of the bimetal thermostat in the conventional fluid clutch type. Therefore, the fan drive power loss can be reduced, and the water temperature of the radiator 1 is detected by the water temperature sensor 2, and the solenoid 3 is turned on / off by the ECU 5 for more accurate fan drive control. Will be able to perform.

이상과 같이 본 발명은 라디에이터의 수온을 검지하여 ECU에 의해 솔레노이드를 온/오프케 함으로써 라디에이터의 수온을 정확히 검출하여 팬클러치를 작동시키게 되므로 그 동작의 정확성을 기할 수 있고, 마찰 클러치부의 마찰력에 의해 팬의 회전을 구동 및 정지케 함으로써 전력손실을 배제하여 경제적인 이득을 도모할 수 있는 효과를 지님과 동시에 엔진의 효율증대를 도모할 수 있게 된다.As described above, the present invention detects the water temperature of the radiator and turns on / off the solenoid by the ECU to accurately detect the water temperature of the radiator to operate the fan clutch so that the operation of the fan clutch can be accurate, and the frictional force of the friction clutch unit can be used. By driving and stopping the rotation of the fan, it is possible to reduce the power loss and achieve economic gains, while at the same time increasing the efficiency of the engine.
