Abstract

본 발명은 실린더와 피스톤부의 윤활작용 및 냉각 작용을 위한 자동차 오일 제트의 구조에 관한 것으로, 이러한 오일 분사구를 커넥팅 로드의 하부에 형성하므로써, 별도의 부품을 필요로 하지 않으며, 또한 이에 따라 피스톤의 설계에 있어서도, 아무런 제약을 주지 않는 것을 목적으로 하며, 본 발명은, 실린더 블록내에서 커넥팅 로드 및 크랭크 샤프트에 결합되어 왕복운동을 하는 피스톤과 실린더의 하부에 오일을 분사시키므로써 윤활막을 제공하여 마찰열을 감소시키며, 또한 냉각 효과를 제공하는 자동차의 오일제트에 있어서, 상기 크랭크 샤프트의 핀 저어널부에 오일 홀이 형성되고, 상기 핀 저어널부에는 커넥팅 로드이 한쪽 단부가 장착되며, 상기 크랭크 샤프트의 핀 저어널부에 장착되는 커넥팅 로드에는 상기 핀 저어널부의 오일 홀에 대응하는 위치에 상향 홀과 연통되어 있는 홀이 제공되어, 상기 크랭크 샤프트로부터 핀 저어널부의 오일 홀을 거쳐 커넥팅 로드의 상향 홀로 오일이 분사되는 것을 특징으로 한다.The present invention relates to the structure of an automobile oil jet for lubricating and cooling the cylinder and the piston, and by forming such an oil injection hole in the lower portion of the connecting rod, no separate parts are required, and accordingly the design of the piston The present invention also provides a lubricating film by injecting oil into the piston and the lower part of the cylinder, which are coupled to the connecting rod and the crankshaft in the cylinder block and reciprocating in the cylinder block. In an oil jet of an automobile which reduces cooling and provides a cooling effect, an oil hole is formed in a pin journal portion of the crankshaft, and the pin journal portion has a connecting rod mounted at one end thereof, and a pin journal portion of the crankshaft. The connecting rod mounted on the pin is connected to the oil hole of the pin journal part. Is a hole that is in communication with the hole in the upward position to provide, via an oil hole from the journal portion pin the crankshaft is characterized in that the up-hole oil of the connecting rod injection.

Claims

In the oil jet of the automobile, which is coupled to the connecting rod and the crankshaft in the cylinder block, the oil is injected to the piston and the lower part of the cylinder, thereby providing a lubrication film to reduce frictional heat and also provide a cooling effect. An oil hole is formed in the pin journal portion of the crankshaft, one end of a connecting rod is mounted to the pin journal portion, and a connecting rod mounted to the pin journal portion of the crank shaft corresponds to an oil hole of the pin journal portion. A hole in communication with an upward hole is provided at a position such that oil is injected from the crankshaft through an oil hole of the pin journal portion to an upward hole of a connecting rod.
