[ 산업상 이용분야 ][Industrial use]
본원 발명은 차량 엔진에 의해 구동되는 에어컨 컴프레서에 동력을 전달해주는 클러치에 관한 것으로 보다 상세하게는 드럼형 마찰 접속 방식의 자동차 에어컨용 마그네트 클러치에 관한 것이다.The present invention relates to a clutch that transmits power to an air conditioner compressor driven by a vehicle engine, and more particularly, to a magnet clutch for an automobile air conditioner of a drum type frictional connection type.
[ 종래기술 ]Prior Art
차량의 냉방을 위해 사용되는 냉매가스는 압축기에서 흡입ㆍ압축되어지는데 압축기의 구동원으로는 엔진의 구동력을 이용하게 되며 엔진의 구동력은 클러치, 주로 전원에 의해 동력 단속이 이루어지는 마그네트 클러치를 사용하여 전달하게 된다.The refrigerant gas used for cooling the vehicle is sucked and compressed by the compressor. The driving source of the compressor is the driving force of the engine, and the driving force of the engine is transmitted by using a clutch, a magnet clutch mainly driven by a power source. do.
제3도는 종래 일반적으로 사용되는 마그네트 클러치(10)를 도시한 것으로 마그네트 클러치(10)는 냉방을 필요로 할 때만 엔진에서 구동력을 압축기(11)로 전달하는 작용을 하게 되는 데 전원이 인가시에는 코일(12)이 여자되어 풀리(13)가 강력한 전자석이 되어 디스크(14, 클러치링)를 흡입하여 일체가 되며 전원이 끊어질 때는 코일(12)여자상태 해제에 따라 자력이 소멸되므로써 스프링(15)탄발에 의해 디스크(14)가 원상 복귀하여 풀리(13)로부터 분리되면서 동력이 끊기게 된다.3 illustrates a magnet clutch 10 that is generally used. The magnet clutch 10 acts to transfer driving force from the engine to the compressor 11 only when cooling is required. The coil 12 is excited and the pulley 13 becomes a strong electromagnet to suck the disk 14 and the clutch ring to be integral. When the power is cut off, the magnetic force is dissipated upon release of the coil 12 to release the spring 15. The disk 14 is returned to its original state by the shot, and the power is cut off while being separated from the pulley 13.
[ 종래기술의 문제점 ][Problems of Prior Art]
그러나 상기와 같은 구조의 마그네트 클러치의 경우 동력 접속이 풀리(13, 또는 로터)측면에 흡착되어지는 디스크(14)의 축방향이동에 의해 이루어지게 되므로써 마찰부의 반경 차이에 따른 선속도가 다르므로 디스크(14)와 풀리(13) 측면의 마모도가 방사 방향으로 다르게 되어 접촉면적이 줄어들어 동력 전달 특성이 불안정해지는 문제점이 지적되고 있다.However, in the case of the magnet clutch of the above structure, the power connection is made by the axial movement of the disk 14 which is adsorbed on the pulley 13 or the rotor side, so the linear velocity is different according to the radius difference of the friction part. It is pointed out that the abrasion degree of the side faces of the 14 and the pulley 13 is different in the radial direction so that the contact area is reduced and the power transmission characteristic becomes unstable.
[ 발명이 해결하고자 하는 과제 ][PROBLEMS TO BE SOLVED BY THE INVENTION]
이에 본원 발명은 상기한 문제점을 감안하여 제안한 것으로서 그의 목적으로 하는 바는 마찰면의 마모가 균일하게 일어나고 마모시에도 동일한 접촉력을 유지하며 공간적 제약을 받지 아니하고 마찰면적의 증가가 가능하여 큰 동력 전달에 유리한 드럼형마찰 접속 방식의 자동차 에어컨용 마그네트 클러치를 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above problems, and its object is to uniformly wear the friction surface, maintain the same contact force during wear, and increase the friction area without being restricted by space. It is an object of the present invention to provide a magnet clutch for an automotive air conditioner having an advantageous drum-type frictional connection method.
[ 과제를 해결하기 위한 수단 ]Means to solve the problem
상기한 목적을 달성하기 위한 본원 발명의 수단은 차량 에어컨 작동시 코일 여자에 의한 풀리의 전자석화로 클러치링을 흡착하여 동력을 전달하는 마그네트 클러치에 있어서, 상기 풀리의 회전축과 동심원인 내원주면으로 형성되는 드럼마찰면과, 상기 코일 여자시의 흡착력에 의해 반경 방향(방사상)으로 확산되어 상기 드럼마찰면에 밀착되는 복수개의 클러치링과;를 포함하여 구성됨을 특징으로 한다.Means of the present invention for achieving the above object is a magnet clutch for absorbing the clutch ring by the electromagnetization of the pulley by the coil excitation during operation of the vehicle air conditioner, the power is formed in the inner peripheral surface concentric with the rotation axis of the pulley And a plurality of clutch rings which are in the radial direction (radial) by the drum friction surface and the suction force during the coil excitation, and are in close contact with the drum friction surface.
[ 실시예 ]EXAMPLE
이하 본 발명의 실시예를 첨부한 도면을 참조하여 상술한다.Hereinafter with reference to the accompanying drawings an embodiment of the present invention will be described in detail.
제1도는 본 발명의 드럼형 마찰접속 방식의 자동차 에어컨용 마그네트 클러치를 나타내는 도면이며, 제2도는 그의 측면도이다.1 is a diagram showing a magnet clutch for an automotive air conditioner of the drum type friction connection method of the present invention, and FIG. 2 is a side view thereof.
도면중 부호 1은 엔진의 크랭크축 회전력을 V벨트를 통해 전달 받는 풀리이며 풀리(1) 몸체 내부에는 코일(2) 뭉치가 배설되어 있다.Reference numeral 1 in the figure is a pulley that receives the crankshaft rotational force of the engine through the V-belt and a bundle of coils 2 are disposed inside the pulley 1 body.
풀리(1)는 베어링(3)에 의해 회전축(4)에 대하여 공회전 가능하며 코일(2)이 여자되어 풀리(1)몸체가 전자석이 될 때 클러치링(5)을 흡착하여 압축기(6)의 회전축을 회전시킨다.The pulley 1 is capable of idling with respect to the rotating shaft 4 by the bearing 3, and when the coil 2 is excited and the pulley 1 body becomes an electromagnet, the pulley 1 adsorbs the clutch ring 5 Rotate the axis of rotation.
상기 풀리(1)의 코일(2) 지지부(7)는 일정두께의 원통상이며 그의 내원주면은 회전축(4)과는 동심원으로 드럼마찰면(8)을 형성한다.The support portion 7 of the coil 2 of the pulley 1 has a cylindrical shape with a constant thickness, and its inner circumferential surface forms a drum friction surface 8 concentrically with the rotation shaft 4.
상기 회전축(4)의 둘레에 방사상으로 복수개가 설치되는 클러치링(5)은 탄성력이 있는 판스프링(9)에 의해 축(4)에 고정되며 상기 클러치링(5)은 드럼마찰면(8)의 곡률반경과 같은 반경의 호형 분할편으로 형성된다.A plurality of clutch rings 5 radially installed around the rotation shaft 4 are fixed to the shaft 4 by an elastic leaf spring 9 and the clutch ring 5 is a drum friction surface 8. It is formed of arc-shaped partition pieces of the same radius as the radius of curvature of.
이와같이 구성된 본원 발명은 에어컨 작동스위치를 켜게되면 코일(2)에 전류가 인가되어 여자되고 이에 따라 풀리(1)는 전자석이 된다.According to the present invention configured as described above, when the air conditioner operation switch is turned on, a current is applied to the coil 2 so that the pulley 1 becomes an electromagnet.
풀리(1)가 자화되면 클러치링(5)을 끌어당겨 드럼마찰면(8)에 밀착시키게 된다.When the pulley 1 is magnetized, the clutch ring 5 is attracted and brought into close contact with the drum friction surface 8.
상기 호형상으로 된 복수개의 클러치링(5)들이 드럼마찰면(8)에 밀착되면 회전력은 풀리(1)→호형 클러치링(5)→스프링(9)→회전축(4)의 순서로 전달되어 압축기(6)가 구동된다.When the plurality of clutch rings 5 having the arc shape are in close contact with the drum friction surface 8, the rotational force is transmitted in the order of the pulley 1 → the arc clutch ring 5 → the spring 9 → the rotation shaft 4. The compressor 6 is driven.
만일 에어컨 스위치가 오프되면 코일(2)의 여자 상태가 해제되어 호형상의 클러치링(5)들은 판스프링(9)의 탄성력으로 복귀하여 드럼마찰면(8)과의 접촉으로부터 분리되어지며 이에 따라 풀리(1)는 베어링(3)에 의해 공회전하므로써 회전축(4)에의 동력 전달은 차단된다.If the air conditioner switch is turned off, the excited state of the coil 2 is released, and the arc-shaped clutch rings 5 return to the elastic force of the leaf spring 9 and are separated from the contact with the drum friction surface 8. Since the pulley 1 is idling by the bearing 3, the power transmission to the rotating shaft 4 is interrupted.
한편 보다 큰 동력이 필요할 시 마찰력을 증대하기 위하여 드럼마찰면(8)과 클러치링(5)의 직경을 증대시키거나 폭을 증대시키므로써 가능하게 된다.On the other hand, it is possible to increase the diameter of the drum friction surface 8 and the clutch ring 5 or increase the width in order to increase the friction when more power is required.
[ 효과 ][ effect ]
이상과 같은 본원 발명에 의하면 마그네트 클러치의 마찰접속방식을 드럼 접속 방식으로 구성하므로써 마찰면의 마모가 균일하고 마모시에도 동일한 접촉력을 유지하며 또한 마찰접촉면의 직경이나 폭의 증대로 미끄러짐이 없이 큰 동력을 전달하는 것이 가능하다.According to the present invention as described above, the friction connection method of the magnet clutch is constituted by the drum connection method, so that the wear of the friction surface is uniform, and the same contact force is maintained even when the friction surface is worn. It is possible to pass.
