Description
본 발명은 차량 엔진의 실린더블록에 관한 것으로, 보다 상세하게는 연소실을 형성하는 라이너의 결합력을 높일 수 있도록 된 차량 엔진의 실린더블록에 관한 것이다.The present invention relates to a cylinder block of a vehicle engine, and more particularly, to a cylinder block of a vehicle engine that can increase the bonding force of the liner forming the combustion chamber.
일반적으로 실린더블록은 엔진의 본체가 되는 부분으로 왕복 운동하는 피스톤링과 마찰을 일으키는 실린더 내벽면의 내마모성 및 길들임성을 향상시키기 위해 실린더 라이너를 별도로 삽입하거나 또는 라이너 없이 실린더블록에 형성되는 연소실의 마찰표면을 특수 처리하게 된다.In general, the cylinder block is a friction portion of the combustion chamber formed in the cylinder block without the liner or by inserting a cylinder liner separately to improve wear resistance and tame resistance of the inner wall of the cylinder causing friction with the piston ring reciprocating to a part of the engine body. The surface is specially treated.
즉, 이러한 실린더블록중 연소실을 형성하는 라이너를 사용하는 실린더블록은 도 1에 도시된 바와 같이, 그 상부로 헤드 개스켓트(30)가 실린더헤드와 함께 장착되어 연소실을 형성하는 라이너(10)와 이를 감싸는 바디(20)로 이루어지되, 상기 실린더블록은 주물이나 또는 알루미늄 다이캐스팅(Die Casting)을 통해 바디(20)를 제작할 때 바디(20)의 보어(Bore)에 미리 제조된 라이너(10)를 삽입시켜 라이너(10)의 외벽이 바디(20)의 보어내벽에 일체로 고착되어지도록 해 제작하게 된다.That is, the cylinder block using the liner forming the combustion chamber of the cylinder block, as shown in Figure 1, the head gasket 30 is mounted with the cylinder head to the upper liner 10 to form a combustion chamber And it is made of a body 20 surrounding it, the cylinder block is a pre-manufactured liner 10 in the bore (Bore) of the body 20 when manufacturing the body 20 through casting or aluminum die casting (Die Casting) By inserting the outer wall of the liner 10 is to be integrally fixed to the inner wall of the bore of the body 20 is manufactured.
그러나, 이와 같은 실린더블록을 이루는 바디(20)와 라이너(10)는 서로 다른 재질로 인해 즉, 상기 바디(20)가 알루미늄재질인데 반해 라이너(10)는 원통형의 실린더로서 슬리브라고도 하며 실리콘, 망간, 니켈, 크롬 등을 포함하는 특수 주철을 재질로 사용하여 원심주조방식으로 제조하게 되므로, 이와 같이 알루미늄과 주철간의 재질 특성상 초기 제작시 바디(20)와 라이너(10)간 접촉 불량이 발생되면 피스톤과 라이너(10)내부와의 마찰에 의해 지속적인 충격이 가해질 때 라이너(10)와 바디(20)사이의 접합부에 간극이 발생돼 결국, 상기 라이너(10)가 바디(20)로부터 이탈되는 문제가 있게 된다.However, the body 20 and the liner 10 constituting such a cylinder block are due to different materials, that is, the body 20 is made of aluminum, while the liner 10 is a cylindrical cylinder, also referred to as a sleeve, silicon, manganese. Since it is manufactured by centrifugal casting method using a special cast iron containing nickel, chromium, etc. as a material, if the poor contact between the body 20 and the liner 10 during the initial production due to the material properties of aluminum and cast iron, the piston When a continuous shock is applied by friction with the inside of the liner 10, a gap is generated at the junction between the liner 10 and the body 20, and thus, the liner 10 is separated from the body 20. Will be.
또한, 상기 라이너(10)와 바디(20)의 재질 차이에 의한 열전달계수의 차이로 인해 엔진의 작동 시 고온·고압이 지속적으로 작용하는 연소실의 조건에 따라 라이너(10)와 바디(20)사이의 접합부에 간극이 발생될 소지가 다분하다는 문제가 있게 된다.In addition, due to the difference in the heat transfer coefficient due to the difference in the material of the liner 10 and the body 20 between the liner 10 and the body 20 in accordance with the conditions of the combustion chamber in which the high temperature and high pressure continuously operate during the operation of the engine. There is a problem that the gap is likely to be generated at the junction of.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 라이너와 바디와의 접촉면적을 증가시켜 제조 후 더욱 큰 고정력을 유지함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and has an object of maintaining a larger fixing force after manufacture by increasing the contact area between the liner and the body.
상기와 같은 목적을 달성하기 위한 본 발명은, 바디의 보어에 미리 제조된 라이너를 삽입시켜 라이너의 외벽이 바디의 보어내벽에 일체로 고착되어지도록 해 제작되되, 상기 라이너의 외주면에는 나선형으로 돌출된 리브가 형성되어진 것을 특징으로 한다.In order to achieve the above object, the present invention is manufactured by inserting a pre-manufactured liner into the bore of the body so that the outer wall of the liner is integrally fixed to the bore inner wall of the body, and protruding spirally on the outer circumferential surface of the liner. A rib is formed.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 차량 엔진의 실린더 구조도이고, 도 3은 본 발명에 따른 라이너의 사시도를 도시한 것인바, 본 발명은 바디(20)의 보어에 미리 제조된 라이너(10)를 삽입시켜 라이너(10)의 외벽이 바디(20)의 보어내벽에 일체로 고착되어지도록 해 제작되되, 상기 라이너(10)의 외주면에는 나선형으로 돌출된 리브(10a)가 형성되어진다.Figure 2 is a cylinder structure diagram of a vehicle engine according to the present invention, Figure 3 is a perspective view of a liner according to the present invention, the present invention by inserting a pre-manufactured liner 10 in the bore of the body 20 The outer wall of the liner 10 is manufactured to be integrally fixed to the bore inner wall of the body 20, and the outer peripheral surface of the liner 10 is formed with a rib 10a protruding helically.
이에 따라, 본 발명은 전술한 종래의 경우와 같이 실린더블록을 제작할 때 먼저, 주물이나 또는 알루미늄 다이캐스팅을 통해 제작되는 바디(20)의 보어에 그외주면에 나선형의 리브(10a)를 형성한 미리 제조된 라이너(10)를 삽입시켜 라이너(10)의 외벽이 바디(20)의 보어내벽에 일체로 고착되어지도록 해 제작하게 된다.Accordingly, the present invention, when manufacturing the cylinder block as in the conventional case described above, first manufactured in advance by forming a spiral rib (10a) on the outer peripheral surface in the bore of the body 20 produced through casting or aluminum die casting The liner 10 is inserted into the outer wall of the liner 10 so as to be integrally fixed to the inner wall of the bore 20.
이와 같이 실린더블록을 이루는 바디(20)에 라이너(10)가 서로 접착되면 라이너(10)의 리브(10a)가 바디(20)에 파고들면서 서로 접촉되어 고정됨과 더불어 라이너(10)의 외면이 바디(20)와 서로 접촉되어 고정되는 2중적인 고정 구조를 형성하게 되므로 비록, 알루미늄재질의 바디(20)와 특수 주철 재질이 라이너(10)가 서로 다른 재질로 제작되더라도 제작 시 바디(20)와 라이너(10)간 접촉 불량이 발생되지 않게 된다.As such, when the liners 10 are bonded to the body 20 forming the cylinder block, the ribs 10a of the liner 10 are fixed in contact with each other while being penetrated into the body 20 and the outer surface of the liner 10 is fixed to the body. Since it forms a double fixed structure that is fixed in contact with each other (20), even if the body 20 and the special cast iron material of the aluminum material liner 10 is made of a different material and the body 20 at the time of manufacture Poor contact between the liners 10 is not generated.
이에 따라, 본 발명의 라이너(10)는 피스톤과 라이너(10)내부와의 마찰에 의해 지속적인 충격이 가해지더라도 라이너(10)와 리브(10a)가 2중으로 접촉되어 고정되므로 바디(20)사이의 접합부에 간극의 발생 소지를 방지할 수 있게 됨은 물론이다.Accordingly, the liner 10 of the present invention is fixed between the body 20 because the liner 10 and the rib 10a are fixed in double contact even when a continuous impact is applied by friction between the piston and the inside of the liner 10. It goes without saying that it is possible to prevent the occurrence of gaps at the joints.
또한, 상기 라이너(10)와 바디(20)의 재질 차이에 의한 열전달계수의 차이가 있다하더라도 리브(10a)가 바디(20)를 파고 들어가 고정되므로 엔진의 작동 시 고온·고압이 지속적으로 작용하더라도 라이너(10)와 바디(20)사이의 접합부에 간극이 발생될 소지가 방지될 수 있게 됨은 물론이다.In addition, even if there is a difference in the heat transfer coefficient due to the material difference between the liner 10 and the body 20, since the rib 10a penetrates the body 20 and is fixed, even if high temperature and high pressure are continuously operated during operation of the engine. Of course, it is possible to prevent the occurrence of a gap in the junction between the liner 10 and the body 20.
이상 설명한 바와 같이 본 발명에 의하면, 실린더블록의 연소실을 형성하는라이너에 나선형상의 돌출된 리브를 형성하여 제작 시 라이너의 외주면과 리브에 의한 2중의 접촉면적을 갖고 고정되어 피스톤과 라이너내부와의 마찰에 의해 지속적인 충격과 엔진의 작동에 따른 고온·고압이 지속적으로 작용하더라도 라이너의 접합부에 간극이 발생될 소지가 방지될 수 있는 효과가 있게 된다.As described above, according to the present invention, a spirally projecting rib is formed on the liner forming the combustion chamber of the cylinder block, and is fixed with a double contact area between the outer circumferential surface of the liner and the rib when fabricated, thereby friction between the piston and the inside of the liner. Due to the continuous impact and high temperature and high pressure due to the operation of the engine continues to be effective to prevent the occurrence of gaps in the junction of the liner.
