본 발명은 기관에 장치되는 크랭크축(crank shaft)에 관한 것으로서, 특히 크랭크축과 플라이휠을 일체로 구성하여, 진동과 소음을 저감하도록 하는 자동차 기관의 크랭크축 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crank shaft installed in an engine, and more particularly, to a crank shaft structure of an automobile engine configured to reduce vibration and noise by integrally constructing a crank shaft and a flywheel.
종래 자동차의 크랭크축은, 복수개의 크랭크가 일정방향으로 배열되고, 크랭크 사이의 중간에 저어널이 연결되어, 양단부에 회전축이 연결되어, 회전축의 일단부에 플랜지에 의해 플라이휠(fly wheel)이 착탈 가능하게 체결되도록 되어 있다.In the crankshaft of a conventional vehicle, a plurality of cranks are arranged in a constant direction, a journal is connected between the cranks in the middle, a rotation shaft is connected to both ends, and a flywheel is removable by a flange at one end of the rotation shaft. It is intended to be fastened.
이와 같이 구성되는 종래 자동차의 크랭크축은, 기관의 크랭크실에 양단의 회전축과 저어널이 회동 가능하게 지지되고, 크랭크에 각기 커넥팅로드가 연결되어, 커넥팅로드에 연결되는 피스톤의 왕복운동을 회전운동으로 전환하고, 플라이휠을 통해 회전이 원활하도록 하여 동력전달장치에 구동력이 전달되도록 되어 있다.In the crankshaft of a conventional vehicle configured as described above, the rotary shaft and the journal at both ends are rotatably supported by the crank chamber of the engine, and the connecting rods are respectively connected to the crank, and the reciprocating motion of the piston connected to the connecting rod is rotated. In turn, the rotation is made smoothly through the flywheel so that the driving force is transmitted to the power transmission device.
그러나, 이러한 종래 자동차의 크랭크축은, 피스톤의 왕복운동을 회전운동으로 전환하는 크랭크축과 원활하게 원운동을 하려고 하는 플라이휠 사이에 회전 불균형이 생겨, 진동이 발생되고 이로 인해 소음이 생기는 문제점이 있었다.However, the crankshaft of such a conventional car has a problem that a rotational imbalance occurs between the crankshaft for converting the reciprocating motion of the piston to the rotational motion and the flywheel which is trying to smoothly move the circular motion, resulting in vibrations and noise.
본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위해, 크랭크축의 플랜지와 플라이휠이 연결장섬유가 감겨지는 원통삽입구에 의해 일체로 형성되어, 크랭크축의 구동시 연결장섬유에 의해 진동이 흡수되도록 하는 자동차 기관의 크랭크축 구조를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, the crankshaft flange and the flywheel is integrally formed by the cylindrical insertion hole is wound around the connecting fiber, so that the vibration is absorbed by the connecting fiber when the crankshaft driving It is to provide a crankshaft structure of an automotive engine.
이하 첨부된 도면에 의하여 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.
본 발명도 제1도에 도시되는 바와 같이, 복수개의 크랭크(10)가 일정방향으로 배열되고, 크랭크(10) 사이의 중간에 저어널(11)이 연결되며, 일단부에 플랜지(12)에 의해 플라이휠(13)이 연결되어, 기관의 크랭크실에 저어널(11)이 회동 가능하게 지지되고, 크랭크(10)에 각기 커넥팅로드가 연결되어, 커넥팅로드에 연결되는 피스톤의 왕복운동을 회전운동으로 전환하도록 되는 것은 종래와 같다. 단, 본 발명은 동일한 외경으로 형성되어 플랜지(12)에 밀착되는 플라이휠(13)의 돌출부와 플랜지(12)의 외주면에 연속장섬유가 감겨지는 원주연결구(21)가 형성되고, 원주연결구(21)의 외주면에 고강도의 원통삽입구(22)이 압입됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 1, a plurality of cranks 10 are arranged in a predetermined direction, and a journal 11 is connected between the cranks 10 and a flange 12 at one end thereof. By the flywheel 13 is connected, the journal 11 is rotatably supported in the crank chamber of the engine, the connecting rod is connected to the crank 10, respectively, the reciprocating motion of the piston connected to the connecting rod is a rotary motion Switching to the same as in the prior art. However, the present invention is formed with the same outer diameter and the circumferential connector 21 is formed in the protrusion of the flywheel 13 is in close contact with the flange 12 and the continuous long fibers are wound on the outer peripheral surface of the flange 12, the circumferential connector 21 It is a basic feature of the technical configuration that the high-strength cylindrical insertion hole 22 is press-fitted to the outer peripheral surface of the).
여기서, 원통삽입구(22)는 보통철(Fe)계의 고강도재에 의해 형성되는 것으로서, 양단부 외주면에 소정간격으로 슬리트가 형성되고, 상기 슬리트에 FRM재의 연결장섬유(22a)가 감기도록 하여, 원주연결구(21)에 압입되도록 하고, 온도차감후 매트릭스(matrix)금속을 가열하고 결합부를 FRM화 함이 바람직하다.Here, the cylindrical insertion hole 22 is formed of a high-strength material of ordinary iron (Fe), slits are formed at predetermined intervals on the outer peripheral surface of both ends, so that the connecting long fibers 22a of the FRM material are wound on the slits. Therefore, it is preferable to press-fit the circumferential connector 21, to heat the matrix metal after the temperature difference, and to form the bonding portion FRM.
이와 같이 구성되는 본 발명은, 원통삽입구(22)에 의해 플라이휠(13)과 크랭크축이 일체로 형성되어, 피스톤의 왕복운동을 회전운동으로 전환하는 크랭크축과 플라이휠(13) 사이에 발생되는 진동이 연속장섬유 및 연결장섬유에 의해 흡수되도록 한다.According to the present invention constituted as described above, the flywheel 13 and the crankshaft are integrally formed by the cylindrical insertion hole 22, and the vibration generated between the crankshaft and the flywheel 13 for converting the reciprocating motion of the piston into the rotational motion. It is to be absorbed by the continuous long fibers and the connecting long fibers.
따라서, 이러한 본 발명은, 플라이휠(13)과 크랭크축이 일체로 형성되고, 크랭크축의 회전시 발생되는 진동이 연결장섬유에 흡수되어 소음이 저감되도록 하는 효과가 있다.Therefore, the present invention has the effect that the flywheel 13 and the crankshaft are integrally formed, and the vibration generated when the crankshaft rotates is absorbed by the connecting filament to reduce the noise.
이상에서 살펴본 바와 같이, 본 발명 크랭크축의 플랜지와 플라이휠이 연결장섬유가 감겨지는 원통삽입구에 의해 일체로 형성되어, 진동과 소음이 저감되도록 하는 매우 유용한 것이다.As described above, the flange and the flywheel of the crankshaft of the present invention are integrally formed by the cylindrical insertion hole in which the connecting long fiber is wound, so that the vibration and the noise are reduced.
