Abstract

본 고안은 자동차에 설치되는 크랭크장치에 관한 것으로, 종래에는 크랭크 아암의 회전 중심축이 실린더의 중앙축상에 위치되도록 구성되어 있으므로 연비 및 출력이 낮고, 충분한 연소를 수행하지 못하는 문제점이 있었다.The present invention relates to a crank device installed in an automobile, and in the related art, since the rotational central axis of the crank arm is configured to be positioned on the central axis of the cylinder, fuel economy and output are low, and there is a problem in that it does not perform sufficient combustion.

따라서 본 고안은 크랭크축(120) 쪽에는 상기 크랭크축(120)과 일체로 타원형의 구동기어(200)를 회동가능하게 설치하고, 상기 구동기어(200)와 이맞물림되도록 출력 쪽에는 상기 플라이 휠(140)과 일체로 종동기어(220)를 설치함으로써, 피스톤(100)의 압축행정시에는 피스톤(100)이 급격하게 상승운동을 하다가 피스톤(100)의 폭발행정시에는 피스톤(100)이 완만하게 하강운동을 하게 됨에 의하여 피스톤(100)의 폭발행정시에 피스톤(100)이 상사점 부분에서 보다 오래 머물게 되므로써, 실린더(180)내의 혼합기가 충분히 연소되고 크랭크축(120)에 연결된 크랭크 아암(170)의 회전 중심축이 실린더(180)의 중앙축상에 위치함에 따라 피스톤(100)의 행정이 짧게 형성되어 연비의 효율 및 출력이 낮고, 충분한 연소를 수행하지 못하는 문제점을 해결할 수 있는 유용한 고안이다.Therefore, the present invention installs an elliptical driving gear 200 integrally with the crank shaft 120 on the crank shaft 120 side so as to be rotatable, and the fly wheel on the output side so as to be engaged with the driving gear 200. By installing the driven gear 220 integrally with the 140, the piston 100 suddenly moves up during the compression stroke of the piston 100, but the piston 100 is gentle during the explosion stroke of the piston 100. Since the piston 100 stays longer at the top dead center portion during the explosion stroke of the piston 100 by the downward movement, the crank arm (which is sufficiently combusted in the cylinder 180 and connected to the crank shaft 120) As the rotational central axis of 170 is located on the central axis of the cylinder 180, the stroke of the piston 100 is formed to be short, so that a useful design that can solve the problem of low fuel efficiency and low output and insufficient combustion can be performed. .

이하, 본 고안의 목적을 효과적으로 달성할 수 있는 바람직한 실시 예로서 그 기술 구성 및 효과를 첨부한 별첨의 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, which are attached to the technical configuration and effects as a preferred embodiment to effectively achieve the object of the present invention.

즉, 도 3은 본 고안의 크랭크장치를 도시한 사시도이고, 도 4는 본 고안의 크랭크장치의 작동상태를 도시한 구성도로서, 이에 예시한 바와같이 본 고안은 피스톤(100)의 왕복운동을 회전운동으로 바꾸는 크랭크축(120)과, 크랭크축(120)에 장착되는 관성바퀴의 플라이 휠(140)과, 크랭크축(120)과 피스톤(100)을 연결하는 커넥팅 로드(160)를 구비하는 크랭크장치에 있어서, 상기 크랭크축(120) 쪽에는 상기 크랭크축(120)과 일체로 타원형의 구동기어(200)를 회동가능하게 설치하고, 상기 구동기어(200)와 이맞물림되도록 출력 쪽에는 상기 플라이 휠(140)과 일체로 종동기어(220)를 설치하여 된 것을 특징으로 하는 것이다.That is, Figure 3 is a perspective view showing a crank device of the present invention, Figure 4 is a configuration diagram showing the operating state of the crank device of the present invention, as illustrated herein, the present invention is a reciprocating motion of the piston 100 A crankshaft 120 which is converted into a rotational movement, a flywheel 140 of an inertia wheel mounted to the crankshaft 120, and a connecting rod 160 connecting the crankshaft 120 and the piston 100. In the crank device, the crankshaft 120 side is provided with a rotatable driving gear 200 integrally with the crankshaft 120, the output side to be engaged with the drive gear 200 It is characterized in that the driven gear 220 is installed integrally with the flywheel 140.

이와 같이 형성된 본 고안은 피스톤(100)이 하사점에서 상사점으로 이동하게 될 때, 크랭크축(120) 쪽에는 크랭크축(120)과 일체로 타원형의 구동기어(200)가 회동가능하게 설치되고, 출력 쪽에는 플라이 휠(140)과 일체로 회동가능하게 종동기어(220)가 설치되므로써 피스톤(100)의 압축행정시에는 피스톤(100)이 급격하게 상승운동을 하다가 피스톤(100)의 폭발행정시에는 피스톤(100)이 완만하게 하강운동을 하게 된다.When the piston 100 is moved from the bottom dead center to the top dead center, the present invention formed as described above has an elliptical drive gear 200 that is integrally formed with the crank shaft 120 and rotatably installed on the crank shaft 120 side. On the output side, the driven gear 220 is rotatably installed integrally with the flywheel 140 so that the piston 100 suddenly moves up during the compression stroke of the piston 100, and then the explosion stroke of the piston 100 is performed.

The central axis of rotation of the crank arm 170 connected to the crank shaft 120 is configured to be located on the central axis of the cylinder 180, that is, the stroke of the piston 100 is formed short so that the efficiency and output of fuel economy are low, and The problem of not performing combustion can be easily solved.

이상에서 상술한 바와같이 본 고안은 크랭크축 쪽에는 크랭크축과 일체로 타원형의 구동기어가 회동가능하게 설치되고, 출력 쪽에는 플라이 휠과 일체로 회동가능하게 종동기어가 설치되어, 피스톤의 폭발행정시에 피스톤이 상사점 부분에서 보다 오래 머물게 되고, 실린더내의 혼합기가 충분히 연소를 수행하게 됨에 따라 엔진의 출력이 향상되고, 연비가 향상되는 유용한 고안이다.As described above, the present invention has an elliptical drive gear integrally formed with the crank shaft on the crankshaft side so as to be rotatable, and a driven gear is installed on the output side so as to be integrally rotatable with the flywheel, thereby exploding the piston stroke. It is a useful design that the piston stays longer at the top dead center and the engine's output is improved and the fuel economy is improved as the mixer in the cylinder performs combustion sufficiently.
