The connection structure of the.
주지된 바와 같이, 자동차의 엔진은 연료와 공기가 혼합된 혼합기가 연소실로 유입되어 연소되므로서, 동력을 얻는 대표적인 내연기관이다.As is well known, the engine of a motor vehicle is a representative internal combustion engine that obtains power by mixing and mixing a fuel and air mixture into a combustion chamber.
이와 같은 자동차 엔진은 연소실에서의 폭발력에 의해 실린더내에서 피스톤이 상, 하 왕복운동되고, 그 피스톤에 연동되는 크랭크기구가 회전되므로서 동력을 얻게 되는 바, 실린더와 피스톤 사이에는 긴밀한 기밀상태가 유지되어야 한다.In such an automobile engine, the piston is moved up and down in the cylinder by the explosive force in the combustion chamber and the crank mechanism interlocked with the piston is rotated to obtain power. Should be.
상기한 자동차 엔진의 개략적인 내부 구조가 제1도에 도시되어 있다.A schematic internal structure of such an automobile engine is shown in FIG.
자동차의 엔진은 실린더(1)에 피스톤(2)이 삽입되고, 그 실린더(2)의 상측에 실린더헤드가 밀폐되어 연소실(3)을 구성하며, 상기 피스톤(2)에 커넥팅로드(4)가 개재되어, 크랭크샤프트(5)가 연결되는 구조로 이루어진다.In the engine of an automobile, a piston (2) is inserted into a cylinder (1), a cylinder head is sealed on the upper side of the cylinder (2) to form a combustion chamber (3), and a connecting rod (4) is connected to the piston (2). Interposed, the crankshaft (5) is made of a structure that is connected.
상기한 커넥팅로드(4)는 피스톤 핀(2a)을 개재하여 피스톤(2)과 회동 가능하게 결합된다.The connecting rod 4 is rotatably coupled to the piston 2 via the piston pin 2a.
여기서, 피스톤(2)는 연소실(3)에서의 폭발압력에 의해 실린더(1)내에서, 상, 하 왕복운동되면서, 그 폭발압력을 커넥팅로드(4)를 통해 전달하여, 크랭크샤프트(5)를 회전시키게 된다.Here, the piston (2) in the cylinder (1) by the explosion pressure in the combustion chamber (3), while the upper and lower reciprocating movement, and transmits the explosion pressure through the connecting rod (4), the crankshaft (5) Will rotate.
이러한 피스톤은 폭발압력을 직접 받기 때문에, 고온강도가 높고 열전도가 잘되는 것이 요구된다. 또한 내마모성이 요구되고 마찰계수가 작아야 된다.Since the piston is directly subjected to the explosion pressure, high temperature strength and good thermal conductivity are required. In addition, wear resistance is required and the coefficient of friction must be small.
이런 까닭에 피스톤의 재질로는 알루미늄 합금의 것이 주로 사용되고 있다.For this reason, aluminum alloy is mainly used as a piston material.
종래 기술에서 설명된 자동차 엔진에 있어서, 피스톤과 커넥팅로드는 엔진의 폭발압력을 직접적으로 전달받는 부품들로 대단히 큰 압력 및 부하를 받게 된다.In the automobile engine described in the prior art, the piston and the connecting rod are subjected to a very large pressure and a load by the components directly receiving the explosion pressure of the engine.
따라서, 피스톤과 커넥팅로드는 서로간에 정밀하게 조립되어 유동이 발생되지 않아야 한다.Therefore, the piston and connecting rod must be assembled precisely with each other so that no flow is generated.
그러나 종래의 피스톤과 커넥팅로드의 연결구조는 소정의 갭이 발생되고 있으며, 이를 해소하기 위한 수단이 없다.However, the connection structure of the conventional piston and the connecting rod has a predetermined gap, there is no means for eliminating this.
이러한 피스톤과 커넥팅로드 사이의 갭은 제1도에 상세하게 도시된 바와 같이, 실린더내에서 상, 하 왕복되는 피스톤이 기울어지도록 하여, 실린더 벽과의 접촉면의 마멸을 증대시키고, 피스톤의 마모 및 소음의 발생을 초래하는 문제점이 있다.This gap between the piston and the connecting rod causes the piston to be reciprocated up and down in the cylinder, as shown in detail in FIG. 1, to increase wear of the contact surface with the cylinder wall, and to abrasion and noise of the piston. There is a problem that causes the occurrence of.
본 고안은 상술한 종래 기술의 문제점을 해소하기 위한 목적에서 제안된 것으로서, 피스톤과 커넥팅로드 사이의 갭을 제거하므로서, 피스톤 및 그 피스톤과 접촉되는 실린더벽의 마멸을 방지하고, 소음을 방지하고자 한다.The present invention is proposed to solve the above-mentioned problems of the prior art, and to eliminate the gap between the piston and the connecting rod, to prevent abrasion of the piston and the cylinder wall in contact with the piston, and to prevent noise. .
