Description
본 고안은 실린더내를 왕복운동하며 팽창행정에서 고온 고압의 가스압력을 받아 케넥팅로드를 거쳐서 크랭크축에 회전력을 주는 피스톤(piston) 구조에 관한 것으로서, 더욱더 상세하게는 피스톤이 왕복운동시 스커트의 마찰저항이 감소되도록 하는 피스톤구조에 관한 것이다.The present invention relates to a piston structure that reciprocates in a cylinder and receives a gas pressure of a high temperature and high pressure in an expansion stroke and gives a rotational force to a crankshaft through a connecting rod. A piston structure for reducing frictional resistance is provided.
종래 피스톤구조는 도 1 에 도시하고 있는 바와 같이, 원통형의 상부면에 헤드부(11)가 형성되고, 상기 헤드부(11)의 하부에는 피스톤링(30)이 설치되는 링그루브(13:Ring groove)와 랜드(12:Land)가 형성되며, 상기 링그루브(13:Ring groove)와 랜드(12:Land)의 하부에는 중앙에 케넥팅로드의 일측단부가 결합되는 체결홈(16)이 관통되어 형성된 스커트부(15:Skirt)가 형성되어 있다.As shown in FIG. 1, a conventional piston structure includes a ring groove 13 having a head portion 11 formed on a cylindrical upper surface, and a piston ring 30 disposed on a lower portion of the head portion 11. A groove 12 and a land 12 are formed, and a coupling groove 16 through which one end of the connecting rod is coupled to the center of the ring groove 13 and the land 12 12 is passed through. A skirt portion 15 (Skirt) formed as a result is formed.
이러한 종래 피스톤구조는 각각의 링그루브(13 :Ring groove)에 피스톤링(30)이 설치되어 피스톤(10:Piston)이 실린더내에 기밀을 유지하고, 오일이 연소실로 들어가는 것을 방지하여 엔진의 성능이 저하되는 것을 방지하게 된다.The conventional piston structure has a piston ring 30 is installed in each ring groove 13 (Ring groove) to keep the piston 10 (Piston) in the cylinder airtight, and prevent the oil from entering the combustion chamber to improve the performance of the engine This prevents the deterioration.
그러나 이러한 종래 피스톤구조는 엔진이 작동중에 실린더(20)벽에 스커트부(15:Skirt)의 외측면이 접하는 것에 의해 실린더(20)내에서 마찰이 발생하게 됨으로서, 열이 발생하게 됨은 물론, 운동저항이 증가하여 많은 동력이 필요로 하게 됨으로서, 불필요한 동력이 손실되는 문제점이 있었다.However, such a conventional piston structure is friction generated in the cylinder 20 by contacting the outer surface of the skirt portion 15 (Skirt) to the wall of the cylinder 20 while the engine is operating, thereby generating heat, as well as movement Since the resistance is increased to require a lot of power, there was a problem that unnecessary power is lost.
본 고안은 상기와 같은 종래의 문제점을 해결하기 위해 실린더의 내측벽면에 접촉되는 스커트부의 외측면에 접촉하는 접촉돌기를 복수개 형성하여, 엔진이 작동중에 스커트부가 실린더 내측벽면에 점접촉이 이루어지는 것에 의해 접촉면이 감소되도록 하는 피스톤구조를 제공하는 데 그 목적이 있다.The present invention provides a plurality of contact projections in contact with the outer surface of the skirt portion in contact with the inner wall surface of the cylinder in order to solve the conventional problems as described above, by the point of contact of the skirt portion on the inner wall surface of the cylinder during the engine The object is to provide a piston structure that allows the contact surface to be reduced.

이하 첨부된 도면에 의하여 본 고안의 그 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention by the accompanying drawings in detail.
본 고안의 피스톤구조도 도 2에 도시하고 있는 바와 같이 원통형의 상부면에 헤드부(11)가 형성되고, 상기 헤드부(11)의 하부에는 피스톤링(30)이 설치되는 링그루브(13 :Ring groove)와 랜드(12:Land)가 형성되며, 상기 링그루브(13 :Ring groove)와 랜드(12:Land)의 하부에는 중앙에 케넥팅로드의 일측단부가 결합되는 체결홈(16)이 관통되어 형성된 스커트부(15:Skirt)가 형성되어 지는 것은 종래와 같다. 단, 본 고안은 상기 스커트부(15:Skirt)의 외측면에 접촉돌기(15a)가 복수개 형성되됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 2, the piston structure of the present invention has a head portion 11 formed on a cylindrical upper surface, and a ring groove 13 in which a piston ring 30 is installed at a lower portion of the head portion 11. Ring grooves and lands 12 are formed, and fastening grooves 16 to which one end of the connecting rod is coupled to a center of the ring grooves 13 and the lands 12 are formed at the bottom of the ring grooves 13. The skirt portion 15 (Skirt) formed through is formed as in the prior art. However, the present invention is characterized in that the technical features that the plurality of contact protrusions (15a) is formed on the outer surface of the skirt portion 15 (Skirt).
이와같이 구성되는 본 고안은 엔진이 구동되는 것에 의해 실린더(20)에 설치된 피스톤(10:Piston)이 왕복운동시 상기 실린더(20)의 내측벽면에 스커트부(15:Skirt)의 외측면으로 돌출되어 형성된 접촉돌기(15a)가 접하며 왕복운동이 이루어 지게 된다.According to the present invention configured as described above, the piston 10 (Piston) installed in the cylinder 20 is driven by the engine to protrude to the outer side of the skirt portion 15: Skirt on the inner wall surface of the cylinder 20 during the reciprocating motion. The contact protrusions 15a formed are in contact with each other to reciprocate.
따라서 이러한 본 고안은 엔진이 작동중 실린더의 내측면에 스커트부(15)의 외측면에 돌출 형성된 접촉돌기(15a)가 점접촉이 이루어지면서 왕복운동이 이루어짐으로서 마찰저항이 감소되어 소음이 감소되고, 상기 마찰로 인한 동력손실이 줄어들게 되며, 엔진효율이 증강됨은 물론, 차량의 연비가 향상되도록 효과가 있다.Therefore, the present invention has a contact resistance (15a) protruding to the outer surface of the skirt portion 15 on the inner surface of the cylinder during the operation of the engine is made of reciprocating movement as the point contact is made friction resistance is reduced noise is reduced In addition, the power loss due to the friction is reduced, the engine efficiency is increased, as well as the fuel economy of the vehicle is improved.
이상에서 살펴본 바와 같이 본 고안은 실린더의 내측면에 접촉하는 스커트부의 외측면에 접촉돌기를 복수개 형성하여, 엔진이 작동중에 스커트부가 실린더 내측벽면과 점접촉이 이루어지는 것에 의해 마찰력이 감소되도록 함으로서, 마찰로 인한 동력 손실을 줄여 엔진의 성능이 향상되도록 하는 매우 유용한 고안인 것이다.As described above, the present invention forms a plurality of contact protrusions on the outer surface of the skirt portion in contact with the inner surface of the cylinder, so that the frictional force is reduced by the point of contact between the skirt portion and the inner wall of the cylinder while the engine is operating, thereby reducing friction. It is a very useful design to improve the performance of the engine by reducing the power loss.
