Description
본 고안은 자동차분야의 피스톤에 관한 것이다.The present invention relates to a piston in the automotive field.
일반적으로 엔진은 실린더내상부로 배기밸브가 양측으로 설치되어 있는데, 상기 밸브는 실린더 위 연소실에 마련된 흡기 구멍과 배기 구멍을 각각 개폐하여 공기와 연료의 혼합기(air-fuel mixture)를 실린더에 들어가게하고, 또 연소된 가스를 내보내는 일을 한다. 동시에 압축 행정과 동력 행정에서는 밸브 시이트에 밀착되어 기밀을 유지하다.In general, an engine has an exhaust valve installed at both sides of an upper portion of a cylinder, and the valve opens and closes the intake and exhaust holes provided in the combustion chamber above the cylinder to enter an air-fuel mixture into the cylinder. In addition, it sends out the burned gas. At the same time, the compression stroke and the power stroke adhere to the valve seat to maintain airtightness.
상기 엔진은 각 행정 즉 실린더내에서 피스톤에 의해 압축 폭팔하는 과정에서 상당한 열이 발생되고 이 열은 지속적으로 냉각을 시켜주어야 된다.The engine generates a significant amount of heat during each stroke, that is, during compression compression by the piston in the cylinder, and this heat must be continuously cooled.
또한 상기 피스톤에도 상당한 열이 발생되게 되는데 실린더블록은 외부로 냉각수공급통로가 형성되어 냉각시켜 줄 수 있지만 도 1에 도시된 바와 같이 피스톤(1)은 오일에 의해 냉각작동을 하게 되는데 상기 피스톤(1)의 일측으로 오일주입구(4)가 형성되고 상단으로 오일통로(5)가 형성되면 오일이 배출되는 오일배출구(6)가 형성되어 피스톤(1)의 상단면(2)에서 발생되는 열을 냉각시켜 주게 된다.In addition, a considerable heat is generated in the piston, but the cylinder block can be cooled by forming a cooling water supply passage to the outside, but as shown in FIG. 1, the piston 1 is cooled by oil. When the oil inlet 4 is formed at one side of the oil passage and the oil passage 5 is formed at the top thereof, an oil outlet 6 through which the oil is discharged is formed to cool the heat generated from the upper surface 2 of the piston 1. Will let you.
그런데 상기 피스톤(1)은 상단면(2)에서 발생된 열을 오일통로로 유입된 오일에 의존하여 냉각시키게 되므로 상기 피스톤(1)을 효과적으로 냉각시켜 줄 수 없는 문제점이 있었던 것이다.However, since the piston 1 cools the heat generated from the upper surface 2 depending on the oil introduced into the oil passage, there is a problem in that the piston 1 cannot be cooled effectively.
본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로, 피스톤의 오일통로에 열전달율이 좋은 삽입부재 고정하므로서, 피스톤에서 전달되는 열을 오일배출구로 유입되는 오일에 의해 효과적으로 냉각시킬 수 있는 피스톤의 냉각구조에 관한 것을 제공함을 목적으로 한다.The present invention has been made in view of the above problems, by fixing the insertion member having a good heat transfer rate to the oil passage of the piston, the cooling structure of the piston that can effectively cool the heat transferred from the piston by the oil flowing into the oil outlet. Its purpose is to provide information about.

상기 목적달성을 위한 본 고안의 구성은, 링홈(3)이 형성된 피스톤(1)의 상단면(2)하부로 오일주입구(4)와 오일배출구(6)를 구비한 오일통로(5)가 형성된 것에 있어서, 상기 오일통로(5)상단에 삽입홈(12)을 형성시켜 삽입부재(10)를 고정한 것을 특징으로 하는 피스톤의 냉각구조를 제공하는 것이다.The structure of the present invention for achieving the above object, the oil passage 5 having the oil inlet 4 and the oil outlet 6 is formed at the bottom of the upper surface (2) of the piston (1) in which the ring groove (3) is formed. It is to provide a cooling structure of the piston, characterized in that the insertion groove 10 is fixed by forming an insertion groove 12 on the upper end of the oil passage (5).
이와 같이된 본 고안을 첨부된 도면에 의거 보다 바람직한 실시예를 상세히 설명하면 다음과 같다.Referring to the present invention in more detail based on the accompanying drawings as described above as follows.
도 2는 본 고안에 따른 피스톤의 일부절개 단면도로서, 상기 피스톤(1)의 외부로 실린더(미도시)내부의 연료를 압축 및 배기가스를 배출할 수 있는 링(미도시)을 삽입할 수 있는 링홈(3)이 형성되고 상부에는 상단면(2)이 형성되어 있으며 상기 상단면(2) 하부에는 오일이 흐를 수 있는 오일통로(5)가 형성되어 있다.Figure 2 is a partial cutaway cross-sectional view of the piston according to the present invention, it is possible to insert a ring (not shown) for compressing the fuel in the cylinder (not shown) and discharge the exhaust gas to the outside of the piston (1) A ring groove 3 is formed, and an upper surface 2 is formed at an upper portion thereof, and an oil passage 5 through which oil flows is formed at a lower portion of the upper surface 2.
상기 오일통로(5)일측에는 오일이 유입될 수 있는 오일주입부(4)가 형성되고 타측에는 오일이 배출되는 오일배출구(6)가 형성되어 있다.One side of the oil passage 5 is formed with an oil inlet 4 through which oil can be introduced, and an oil outlet 6 through which oil is discharged is formed at the other side.
삽입부재(10)는 오일통로(5)의 상단에 형성된 삽입홈(12)에 삽입고정되어 상기 피스톤(1)의 상단면(2)에서 발생된 열을 쉽게 흡수 할 수 있도록 되어 있으며, 상기 삽입부재(10)는 열흡수율이 좋은 주철재등으로 하는 것이 바람직하다.The insertion member 10 is inserted into and fixed in the insertion groove 12 formed at the upper end of the oil passage 5 so that the heat generated from the upper surface 2 of the piston 1 can be easily absorbed. The member 10 is preferably made of a cast iron material having a good heat absorption rate.
이와 같이된 본 고안은, 피스톤(2)이 흡기, 압축, 점화, 폭발 및 배기의 과정을 거치면서 크랭크 샤프트(미도시)를 회전시키게 됨에 따라 오일이 상기 크랭크 샤프트의 작동에 의해 피스톤(1)의 오일주입부(4)로 오일이 주입되고 이 오일은 오일통로(5)를 따라 다시 오일배출구(6)로 배출되게 된다.The present invention thus achieved, as the piston 2 rotates a crankshaft (not shown) while undergoing a process of intake, compression, ignition, explosion and exhaust, oil is caused by the operation of the crankshaft. Oil is injected into the oil injection portion 4 of the oil is discharged back to the oil outlet (6) along the oil passage (5).
그리고 상기 오일배출구(6)를 지나는 오일은 피스톤(1)이 작동되어 상단면(2)에서 발생된 열이 삽입부재(10)에 전달되어 있으므로 이 삽입부재(10)의 열을 상기 오일에 의해 냉각시켜주게 되는 것이다.And the oil passing through the oil outlet (6) is the piston (1) is operated so that the heat generated in the upper surface (2) is transmitted to the insertion member 10, the heat of the insertion member 10 by the oil It will be cooled.
따라서 오일통로내의 삽입부재에 의해 피스톤의 상단면에서 발생된 열을 쉽게 흡수하고 이 열은 오일에 의해 냉각시켜 주게 되므로 냉각효과를 상승시킨 유용한 고안인 것이다.Therefore, the heat generated from the upper surface of the piston by the insertion member in the oil passage is easily absorbed by the oil is a useful design to increase the cooling effect because it is cooled by the oil.
본 고안은 피스톤에 관한 것으로, 특히 피스톤의 오일통로에 열전단율이 좋은 삽입부재 고정하므로서, 피스톤에서 전달되는 열을 오일배출구로 유입되는 오일에 의해 효과적으로 냉각시킬 수 있는 피스톤의 냉각구조에 관한 것이다.The present invention relates to a piston, and more particularly to a cooling structure of a piston that can effectively cool the heat transmitted from the piston by the oil flowing into the oil outlet by fixing the insertion member having a good thermal shear rate in the oil passage of the piston.
