The piston 4 is mounted on the cylinder block 5, and an oil gallery 6 is mounted on one side of the cylinder block 5, and an oil jet 7 for injecting lubricant through the oil gallery 6 is provided. It is formed.

상기와 같이 형성되는 종래의 자동차용 피스톤 핀의 윤활방식구조는 피스톤의 폭발력을 크랭크 샤프(1)에 전달시켜 주는 컴 로드(2)는 피스톤 핀(3)에 의하여 피스톤(4)과 연결되어 있는 것이다.In the conventional lubrication system of the piston pin for automobiles formed as described above, the compressor rod 2 which transmits the explosive force of the piston to the crankshaft 1 is connected to the piston 4 by the piston pin 3. will be.

여기서 컴 로드(2)의 소단부와 피스톤 핀(3)에 의하여 피스톤(4) 사이의 마찰을 극소화시키기 위해서 윤활유를 공급하는데 일반적으로 실린더 블록(5)내의 오일 갤러리(6)를 통해서 나온 윤활유를 실린더 블록(5)에 부착된 오일 젯(7)으로 윤활유를 분사하여 피스톤 핀(4)과 컴 로드(2)의 소단부에 공급하도록 형성한 것이다.The lubricant is supplied to minimize the friction between the piston (4) by the small end of the come rod (2) and the piston pin (3). In general, the lubricant from the oil gallery (6) in the cylinder block (5) Lubricating oil is injected to the oil jet 7 attached to the cylinder block 5 so as to be supplied to the small end of the piston pin 4 and the comb rod 2.

상기와 같은 방법은 부품수의 증가로 인해서 재료비가 많이 소모되는 문제점이 있는 것이다.The method as described above has a problem that a lot of material costs due to the increase in the number of parts.

본 발명은 상기와 같은 문제점을 해결하기 위해서 안출한 것으로서 오일의 분출 대신에 컴 로드의 대단부에 피스톤 방향으로 오일 홀을 만들어 크랭크 샤프트의 오일 갤러리를 통해 나오는 오일을 직접 피스톤 핀 방향으로 분사시키는 시스템으로서 부품수를 절감하고 이에 따라 원가를 절감할 수 있는 자동차용 피스톤 핀의 윤활방식구조를 제공하는 것이다.The present invention has been made in order to solve the above problems, instead of squirting oil instead of ejecting the oil in the direction of the piston in the direction of the piston to make oil holes through the oil gallery of the crankshaft directly in the direction of the piston pin system It is to provide a lubrication structure of the piston pin for automobile that can reduce the number of parts and thus the cost.
