본 고안은 자동차용 냉각장치에 관한 것으로, 특히 냉각수의 적정온도에 따라 작동되도록 동력을 차단 및 연결하여주는 단속수단을 구비하여 엔진과 함께 항시 회전함에 따른 엔진시동시의 구동부하를 절감하고, 초기시동시 냉각된 저온 냉각수의 강제순환에 따른 불필요한 동력 손실을 방지한 클러치식 냉각수 펌프에 관한 것이다.The present invention relates to a cooling device for automobiles, in particular, having an intermittent means for disconnecting and connecting the power to operate according to the proper temperature of the coolant to reduce the driving load at the time of starting the engine due to rotation at all times with the engine, The present invention relates to a clutch type coolant pump which prevents unnecessary power loss due to forced circulation of cooled low temperature coolant at startup.

일반적으로 자동차용 냉각장치에 사용되는 냉각수 펌프는 냉각수를 순환시키는 장치로써, 주로 원심펌프(centrifugal pump)를 사용하며, 임펠러(impeller)의 회전에 의한 원심력 발생을 이용해서 냉각수를 바깥둘레로 뿜어내므로 펌프작용을 수행한다. 제1도에 도시한 바와 같이 종래 기술에 따른 냉각수 펌프는 엔진의 크랭크축과 V벨트로 연결되어 구동되는 풀리(10)와, 상기 풀리(10)와 결합되어 회전하는 중심축(60)과, 냉각수 펌프의 외형을 이루는 케이스(30)와, 상기 중심축(60)과 상기 케이스(30)사이의 마찰력을 감소시키기 위한 베어링(20)과, 상기 중심축(60)에 결합되어 원심력을 발생하는 임펠러(70)와, 상기 베어링(20)에 냉각수가 침투하지 못하도록 밀봉작용을 수행하는 밀폐재(80)로 이루어져 있으며, 상기 케이스(30)에 형성된 유입구(40)를 통해 냉각수가 유입되면 임펠러(70)의 회전에 의해 냉각수가 바깥둘레로 뿜어져 유출구(50)를 통해 엔진 각부에 전달하므로 냉각된 냉각수를 연속적으로 순화시킨다.Generally, the cooling water pump used in the automotive cooling system is a device for circulating the cooling water, and mainly uses a centrifugal pump, and uses the centrifugal force generated by the rotation of the impeller to pump the cooling water outward. Therefore, pumping is performed. As shown in FIG. 1, the cooling water pump according to the related art includes a pulley 10 driven by being connected to a crankshaft of an engine and a V-belt, a central shaft 60 coupled with the pulley 10 to rotate, The case 30 forming the outer shape of the cooling water pump, the bearing 20 for reducing the friction force between the central axis 60 and the case 30, and is coupled to the central axis 60 to generate a centrifugal force An impeller 70 and a sealing member 80 which performs a sealing function to prevent cooling water from penetrating the bearing 20, and when the coolant is introduced through the inlet 40 formed in the case 30, the impeller ( By the rotation of 70) the cooling water is sprayed to the outer circumference and transmitted to the engine parts through the outlet 50 so that the cooled cooling water is continuously purified.

상기와 같은 종래 기술에 따른 냉각수 펌프는 크랭크축에 의해 구동되므로 엔지 시동시 시동모터에 의해 크랭크축이 구동될 때 동시에 구동되므로 초기 시동시 구동부하로 작용되어 시동모터의 구동력에 저항으로 작용되며, 초기 시동후 이미 저온냉각되어 있던 냉각수를 강제 순환시키므로 불필요한 동력손실을 초래하는 문제점이 발생되었다.Since the cooling water pump according to the prior art as described above is driven by the crankshaft and driven at the same time when the crankshaft is driven by the starter motor at engine start, it acts as a driving load at the initial start and acts as a resistance to the driving force of the starting motor. After the initial start, forced cooling of the coolant, which has already been cooled, has caused a problem of unnecessary power loss.

따라서, 상기와 같은 문제점을 해소하기 위해 본 고안은 안출된 것으로, 냉각수의 적정 온도까지는 냉각수 펌프가 작동되지 않으며, 적정온도 이상이 되면 냉각수 펌프가 작동되도록 함으로서, 초기 엔진 시동시 불필요한 부하가 작용되지 않도록 하고, 냉각작용이 필요한 적정온도에 이르러 냉각수를 순환시키므로 엔진의 동력을 효과적으로 사용하며, 초기 시동성이 향상되는 클러치식 냉각수 펌프를 제공하는데 본 고안의 목적이 있다.Therefore, the present invention has been devised to solve the above problems, the coolant pump does not operate until the proper temperature of the coolant, and when the coolant pump is operated above the proper temperature, unnecessary load is not acted upon during initial engine start-up. It is an object of the present invention to provide a clutch-type coolant pump that effectively uses the power of the engine and improves the initial startability because it circulates the coolant to reach an appropriate temperature that requires a cooling action.

상기 본고안의 목적은 외형을 이루는 케이스부와, 원심력을 이용하여 펌프작용을 수행하는 임펠러와, 상기 임펠러와 연결되어 회전하는 회전축과, 냉각수의 온도를 감지하기 위한 수온감지공과, 냉각수온에 의해 상기 임펠러의 구동력을 단속하는 클러치수단과, 상기 클러치수단과 상기 회전축의 결합후 고정하는 고정핀 및 고정너트를 구비한 클러치식 냉각수 펌프에 의해 달성될 수 있다.The object of the present invention is the case portion forming the appearance, the impeller performing a pump action using a centrifugal force, a rotating shaft connected to the impeller and rotated, a water temperature sensing hole for sensing the temperature of the coolant, and the cooling water temperature It can be achieved by a clutch-type coolant pump having a clutch means for clamping the driving force of the impeller, a fixing pin and a fixing nut for fixing after coupling the clutch means and the rotary shaft.

이하, 본 고안에 따른 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다. 제2도는 본 고안에 따른 클러치식 냉각수 펌프의 내부구조를 도시한 부분 단면도이며, 제3도는 제2도의 분해 사시도로써, 본 고안에 따른 클러치식 냉각수 펌프는 외형을 이루는 케이스부(15)와, 원심력을 이용하여 펌프작용을 수행하는 임펠러(25)와, 상기 임펠러(25)와 연결되어 회전하는 회전축(45)과, 냉각수의 온도를 감지하기 위한 수온감지공(35)과, 냉각수온에 의해 상기 임펠러의 구동력을 단속하는 클러치수단(200)과, 상기 클러치수단(200)과 상기 회전축(45)을 결합후 고정하는 고정핀 및 고정너트(160,165)를 구비하고, 상기 클러치수단(200)이 냉각수온에 의해 팽창 및 수축하는 왁스재(65)와, 상기 왁스재(65)에 이해 좌우로 이동하는 클러치링(75)과, 엔진 크랭크축에 의해 구동되는 클러치풀리(120)와, 마찰재(110)를 구비하여 상기 클러치링(75)의 이동에 의해 상기 클러치풀리(120)와 결합 및 분리되는 클러치판(100)과, 상기 각부품간의 접촉마찰력을 감소시키기 위한 베어링들(55,85,90,130,140)로 이루어진다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. Figure 2 is a partial cross-sectional view showing the internal structure of the clutch type coolant pump according to the present invention, Figure 3 is an exploded perspective view of Figure 2, the clutch type coolant pump according to the present invention is the case portion 15 that forms the appearance, Impeller 25 to perform a pumping action using a centrifugal force, a rotating shaft 45 is connected to the impeller 25 and rotated, a water temperature sensing hole 35 for sensing the temperature of the coolant, by the coolant temperature Clutch means (200) for controlling the driving force of the impeller, and fixing pins and fixing nuts (160,165) for fixing and coupling the clutch means 200 and the rotary shaft 45, the clutch means 200 is A wax material 65 that expands and contracts with cooling water temperature, a clutch ring 75 that moves left and right to the wax material 65, a clutch pulley 120 driven by an engine crankshaft, and a friction material ( 110 is provided to allow the clutch ring 75 to move. And the clutch plate 100 is coupled to and separate from the clutch pulley (120), comprises a bearing with (55,85,90,130,140) for reducing the contact friction between the respective components.

따라서, 상기와 같은 구조로 이루어진 본 고안에 따른 클러치식 냉각수 펌프는 흐르는 냉각수의 온도를 수온감지공(35)이 전달받아 인접한 왁스재(65)에 전달하고, 냉각수온이 저온일때는 클러치판(100)과 클러치풀리(120)가 서로 이격된채 임펠러(25)는 정지되어 있으므로 냉각수 순환작용은 정지되게 된다. 엔진 시동후 가열된 냉각수의 온도가 냉각작용이 필요한 적정온도에 이르면 수온감지공(35)이 가열된 냉각수온을 상기 왁스재(65)에 전달하여 왁스재(65)의 팽창에 따른 클러치링(75)의 이동이 이루어지고, 상기 왁스재(65)의 팽창에 의해 밀려진 클러치링(75)은 클러치판(100)을 밀어 마찰재(110)가 클러치풀리(120)에 압착 되도록 하므로 상호 압착된 클러치판(100)과 클러치풀리(120)는 클러치풀리(120)에 전달된 엔진 크랭크축의 회전력에 의해 함께 회전하여 마찰재(110), 클러치판(100), 회전축(45), 임펠러(25)의 순으로 회전력을 전달하고 임펠러(25)를 회전시켜 냉각수 순환을 위한 펌프작용을 수행한다.Therefore, the clutch type coolant pump according to the present invention having the structure as described above receives the temperature of the flowing cooling water by the water temperature sensing hole 35 and transmits it to the adjacent wax material 65, and when the cooling water temperature is low, the clutch plate ( 100 and the clutch pulley 120 are spaced apart from each other because the impeller 25 is stopped, the cooling water circulation is stopped. After the engine starts, when the temperature of the heated coolant reaches an appropriate temperature that requires a cooling action, the water temperature sensing hole 35 transfers the heated coolant temperature to the wax material 65 and thus clutches the expansion of the wax material 65 ( 75 is moved, and the clutch ring 75 pushed by the expansion of the wax material 65 pushes the clutch plate 100 so that the friction material 110 is pressed against the clutch pulley 120 so as to be mutually compressed. The clutch plate 100 and the clutch pulley 120 rotate together by the rotational force of the engine crankshaft transmitted to the clutch pulley 120, so that the friction material 110, the clutch plate 100, the rotation shaft 45, and the impeller 25 In order to transmit the rotational force and rotate the impeller 25 performs a pump action for cooling water circulation.

따라서, 본 고안에 따른 클러치식 냉각수 펌프는 냉각수의 온도를 감지하기 용이하도록 인접된 왁스재의 팽창 및 수축작용을 이용하여 마찰재를 구비한 클러치판을 엔진으로부터 동력을 전달받는 클러치풀리에 연결 및 이격시키므로 냉각수온에 따라 냉각수펌프를 작동시킬수 있으므로 불필요한 동력손실을 방지하고, 초기 시동시 엔진에 작용하는 구동부하를 최소화할수 있는 이점이 있다.Therefore, the clutch-type coolant pump according to the present invention connects and spaces the clutch plate with the friction material to the clutch pulley that receives power from the engine by using the expansion and contraction action of the adjacent wax material so as to easily sense the temperature of the cooling water. Since the coolant pump can be operated according to the coolant temperature, there is an advantage of preventing unnecessary power loss and minimizing the driving load acting on the engine at initial start-up.
