자동차의 체인가이드 체결구조{Conclusion structure of chain guide for automobiles}Conclusion structure of chain guide for automobiles}

본 발명은 자동차의 체인가이드 체결구조에 관한 것으로서 더욱 상세히는 체인가이드를 실린더블록과 결합시 상하에 나사결합시키는 방법 이외에 체인가이드의중앙에 핀공을 실린더블록에는 지지핀을 돌설하여 상기 지지핀이 핀공속으로 들어가 체인가이드의 중앙부를 지지토록 하므로서 타이밍체인의 장력이 체인가이드의 중앙부에 가해지더라도 체인가이드가 구부러지거나 부러지는등 변형될 우려가 없도록 한 자동차의 체인가이드 체결구조를 제공하기 위한 것이다.The present invention relates to a chain guide fastening structure of an automobile. More specifically, in addition to the method of screwing the chain guide up and down when the chain guide is coupled to the cylinder block, the support pin is pinned by protruding a support pin into the center of the chain guide. It is to provide a chain guide fastening structure of a vehicle in which there is no fear that the chain guide may be deformed, such as bending or breaking, even if the tension of the timing chain is applied to the center of the chain guide by entering the airspeed to support the center of the chain guide.

일반적으로 자동차의 동력발생장치는 엔진을 포함하는데, 상기의 엔진은 흡기장치를 통하여 혼합기를 연소실로 흡입하고, 이 혼합기를 점화장치에 의하여 연소시킴으로써 구동력을 발생시킨후 배기장치를 통하여 배기가스를 외부로 배출시킴으로서 차량의 주행이 이루어지도록 하는 것이다.In general, a power generator of an automobile includes an engine, which generates suction power by injecting a mixer into a combustion chamber through an intake apparatus, and burns the mixer by an ignition device to generate driving force, and then exhausts the exhaust gas through an exhaust system. By discharging the car to drive the vehicle.

이러한 엔진은 실린더블록과 실린더헤드 그리고 상기 실린더블록의 내부를 슬라이드 이동하는 피스톤, 상기 피스톤과 연결되는 크랭크축, 그리고 상기한 크랭크축으로 저달된 동력을 캠축 등에 전달하기위한 크랭크축풀리 등으로 이루어지고 잇으며, 상기한 크랭크축과 캠축은 타이밍벨트나 타이밍체인등으로 연결되어 정확한 밸브의 개폐와 점화시기가 적정하게 이루어지도록 하고 있다.The engine consists of a cylinder block, a cylinder head and a piston for sliding the inside of the cylinder block, a crank shaft connected to the piston, and a crank shaft pulley for transmitting the power stored in the crank shaft to a cam shaft. The crankshaft and the camshaft are connected to each other by a timing belt or a timing chain, so that the correct opening and closing of the valve and the ignition timing are performed properly.

그리고 이러한 캠축의 구동방식은 기어구동식(Gear Drive)과 체인구동식 (Chain Drive)과 벨트구동식(Belt Drive)으로 구분할수 있는데, 여기서는 체인구동식에 대하여 설명하기로 한다.In addition, the driving method of the camshaft can be divided into a gear drive type (Gear Drive), a chain drive type (Chain Drive) and a belt drive type (Belt Drive), the chain drive type will be described here.

즉, 체인구동식은 캠축의 구동을 체인으로 하는 것이며, 크랭크축과 캠축에는 타이밍기어 대신 체인스프로킷이 설치되어 있고, 스프로킷의 재질은 강 또는 주철로 되어 있으며, 체인으로는 사일런트체인이나 롤러체인이 사용된다.In other words, the chain drive type is to drive the cam shaft as a chain, the chain sprocket is installed on the crankshaft and camshaft instead of the timing gear, and the sprocket is made of steel or cast iron, and the chain is used by a silent chain or a roller chain. do.

이러한 체인구동식은 전동능력이 크고 너비를 좁게할수 있다는 장점이 있는반면에 마모나 신장에 따라 소리의 발생이심해지며 전달될 수 있는 속도에 한계가 있고 무거운 단점이 있다.The chain drive type has the advantage of having a large electric power and a narrow width, while the generation of sound increases with wear and elongation, and the speed that can be transmitted is limited and has a heavy disadvantage.

또한 체인이 체인스프로킷에 제대로 치합되게 하기위하여 실린더블록에는 가격이 비교적 저렴한 플라스틱 재질의 체인가이드를 설치하여 상기 체인가이드가 체인의 일단을 밀어주는 역활을 수행하도록 하는 것이다.In addition, in order to ensure that the chain is properly engaged with the chain sprocket, the cylinder block is installed on the cylinder block so that the chain guide pushes one end of the chain.

그런데 종래의 체인가이드는 실린더블록에 설치시 상측과 하측만을 나사결합하여 고정시키고 있는데, 이는 체인가이드의 중앙부위는 고정이 안된 상태이기 때문에 체인시스템 구동시 타이밍체인에 걸린 장력에 의하여 체인가이드의 중앙부위가 심하게 구부러지거나 부러지는등의 많은 문제가 발생되는 것이다.However, the conventional chain guide is fixed by screwing only the upper side and the lower side when installed in the cylinder block. Since the central part of the chain guide is not fixed, the chain guide is driven by the tension applied to the timing chain when the chain system is driven. Many problems occur, such as severely bent or broken areas.

따라서 이를 방지하기 위해 체인가이드의 재질을 금속제로 바꾸거나 체인가이드의 두께를 두껍게 하여 체인가이드가 변형되는 것을 방지할 수도 있으나 이는 중량증가및 부품비가 증가하는 폐단이 있는 것이다.Therefore, in order to prevent this, the material of the chain guide may be changed to metal or the chain guide may be thickened to prevent the chain guide from being deformed.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해소하기 위하여 발명된 것으로서, 본 발명의 목적은 체인가이드의 중심부위가 타이밍체인의 장력에 의해 구부러지거나 부러지는등 변형되는 것을 미연에 방지할 수 있는 자동차의 체인가이드 체결구조를 제공하는데 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, and an object of the present invention is to prevent the deformation of the chain guide in the center portion of the chain guide bent or broken by the tension of the timing chain. It is to provide a chain guide fastening structure of an automobile.

이러한 본 발명의 목적은 체인가이드의 중앙에는 핀공을 형성하고, 실린더블록에는 상기 핀공과 대응된 위치에 지지핀을 돌설하여 상기 핀공에 끼워지는 지지핀에 의해 체인가이드의 중앙이 지지되게 구성하므로써 달성되는 것이다.The object of the present invention is achieved by forming a pin hole in the center of the chain guide, the cylinder block protruding the support pin at a position corresponding to the pin hole so that the center of the chain guide is supported by a support pin fitted to the pin hole. Will be.

이와 같은 본 발명은 실린더블록에 형성된 지지핀이 체인가이드의 중앙에 형성된 핀공에 끼워져 체인가이드를 지지하고 있으므로 타이밍체인의 장력에 의해 체인가이드의 중앙부위가 변형되는 것을 미연에 방지하여 내구성이 향상되도록 하므로서 상기 목적을 효과적으로 달성할 수 있다.In the present invention, the support pin formed in the cylinder block is inserted into the pin hole formed in the center of the chain guide to support the chain guide.

도 1 은 본 발명의 체인가이드가 설치된 상태를 예시한 사시도이고, 도 2 는 본 발명의 체인가이드가 실린더블록에 설치되는 상태를 예시한 요부 사시도로서 이에 도시된 바와같이 본 발명은 양단에 나사삽입공(110)이 형성된 체인가이드(100)를 실린더블록(200)에 형성한 나사공(210)에 나사(300)로 결합함에 있어서, 상기 체인가이드(100)의 중앙에는 핀공(120)을 형성하고, 실린더블록(200)에는 상기 핀공(120)과 대응된 위치에 지지핀(220)을 돌설하여 상기 핀공(120)에 끼워지는 지지핀(220)에 의해 체인가이드(100)의 중앙이 지지되게 한 것을 특징으로 하는 것으로서 도면중 미설명 부호(400)은 타이밍체인이고, (500)은 체인스프로킷이다.1 is a perspective view illustrating a state in which the chain guide of the present invention is installed, and FIG. 2 is a perspective view illustrating main parts of the chain guide of the present invention installed in the cylinder block, as shown in FIG. In coupling the chain guide 100 formed with the ball 110 to the screw hole 210 formed in the cylinder block 200 with the screw 300, a pin hole 120 is formed in the center of the chain guide 100. The center of the chain guide 100 is supported by the support pin 220 which is inserted into the pin hole 120 by protruding the support pin 220 at a position corresponding to the pin hole 120 to the cylinder block 200. In the drawings, reference numeral 400 denotes a timing chain, and 500 denotes a chain sprocket.

이러한 본 발명은 타이밍체인(400)이 체인스프로킷(500)에 제대로 치합될 수 있도록 실린더블록(200)에 설치되어 타이밍체인(400)의 일단을 밀어주는 역할을 수행하는 체인가이드(100)가 타이밍체인(400)의 장력를 견디지 못하고 부러지거나 구부러지는등 변형되는 것을 미연에 방지할 수 있도록 한 것이다.The present invention is installed in the cylinder block 200 so that the timing chain 400 is properly engaged with the chain sprocket 500, the chain guide 100 serves to push one end of the timing chain 400 timing Will not be able to withstand the tension of the chain 400 is broken or bent to prevent it in advance.

즉, 본 발명의 체인가이드(100)를 설치하기 위해서는 도 2 에서 도시한 바와같이 체인가이드(100)를 실린더블록(200)에 밀착시켜 상기 체인가이드(100)에 형성된 나사삽입공(110)과 실린더블록(200)에 형성된 나사공(210)이 일치되도록 한후 나사(300)를 체인가이드(100)의 외측에서부터 즉, 나사삽입공(110)과 나사공(210)을 관통되도록 한후 회동시켜 체인가이드(100)를 실린더블록(200)과 결합토록 하는 것은 종래와 마찬가지이다.That is, in order to install the chain guide 100 of the present invention, as shown in FIG. 2, the chain guide 100 is in close contact with the cylinder block 200 and the screw insertion hole 110 formed in the chain guide 100. After the threaded holes 210 formed in the cylinder block 200 are matched, the screw 300 is rotated from the outside of the chain guide 100, that is, the threaded insertion holes 110 and the threaded holes 210 are penetrated and then rotated. The guide 100 is coupled to the cylinder block 200 as in the prior art.

그러나 본 발명에서 중요한 것은 체인가이드(100)의 중앙에는 핀공(120)이 형성되어 있고, 실린더블록(200)에는 상기 핀공(120)에 끼워지는 지지핀(220)이 돌설되어 있으므로 체인가이드(100)를 실린더블록(200)과 결합시키기 위해서 체인가이드(100)를 실린더블록(200)에 밀착시키면 상기 핀공(120)속으로 지지핀(220)이 자연적으로 들어가게 되는 것이다.However, the important thing in the present invention is the pin hole 120 is formed in the center of the chain guide 100, the cylinder block 200 is supported by the support pin 220 to be fitted to the pin hole 120, so the chain guide 100 In order to couple the chain guide 100 to the cylinder block 200 in order to couple the cylinder block 200, the support pin 220 naturally enters the pin hole 120.

이처럼 핀공(120)속으로 지지핀(220)이 들어가 체인가이드(100)의 중앙부를 지지하게되면 타이밍체인(400)의 장력에 의하여 체인가이드(100)의 중앙부에 힘이 가해지더라도 체인가이드(100)의 중앙부위가 구부러지거나 부러지는등 변형될 우려가 전혀없는 것이다.As such, when the support pin 220 enters the pin hole 120 to support the central portion of the chain guide 100, the chain guide 100 may be applied even if a force is applied to the central portion of the chain guide 100 by the tension of the timing chain 400. There is no fear of deformation such as bending or breaking of the central part.

그리고 체인가이드(100)가 변형되는 것을 방지하기 위해 종래에 체인가이드의 재질을 금속재로 하거나 체인가이드를 두껍게 제작하므로 인하여 중량증가및 부품비가 증가하는 문제점을 용이하게 해결할 수 있는 것이다.In order to prevent the chain guide 100 from being deformed, it is possible to easily solve the problem of weight increase and component cost increase because the chain guide is made of metal or the chain guide is made thick.

이상에서와 같이 본 발명은 체인가이드의 중앙에 형성된 핀공에 지지핀이 끼워져 체인가이드를 지지하므로 타이밍체인의 장력에 의해 체인가이드가 변형될 우려가 전혀 없어 내구성이 향상되는 것은 물론 체인가이드의 재질을 플라스틱으로 구성하므로 부품비가 저렴한 매우 유용한 발명이다.As described above, since the support pin is inserted into the pin hole formed at the center of the chain guide to support the chain guide, there is no fear that the chain guide may be deformed by the tension of the timing chain. It is a very useful invention because it is made of plastic and its parts cost is low.
