본 고안은 차량 등에 장착되는 엔진의 실린더블럭과 오일팬의 체결구조에 관한 것으로, 특히 실린더블럭과 오일팬 사이에 장착되는 크랭크샤프트의 베어링이 편마모되는 것을 방지할 수 있도록 된 실린더블럭과 오일팬의 체결구조에 관한 것이다.The present invention relates to a fastening structure of a cylinder block and an oil pan of an engine mounted on a vehicle. In particular, the cylinder block and oil pan of the crankshaft bearing mounted between the cylinder block and the oil pan can be prevented from being worn out. It relates to a fastening structure.
일반적으로 차량 등에 장착되는 엔진은, 흡배기 매니폴드와 각종 밸브기구 및 점화플러그 등이 장착된 실린더헤드와, 이 실린더헤드가 상부에 체결되면서 내부에서 왕복운동하는 피스톤과 함께 연소실을 형성하는 실린더블럭, 이 실린더블럭의 하부에 장착되어 엔진의 윤활오일을 저장하는 오일팬을 갖추고 있다.In general, an engine mounted on a vehicle includes a cylinder block including an intake / exhaust manifold, various valve mechanisms, spark plugs, and the like, and a cylinder block which forms a combustion chamber together with a piston reciprocating therein as the cylinder head is fastened to an upper portion thereof. It is mounted on the lower part of the cylinder block and has an oil pan for storing lubricating oil of the engine.
그리고 상기 실린더블럭과 오일팬 사이에는 실린더블럭의 내부에서 왕복운동하는 피스톤과 연결되어 이 피스톤의 직선왕복운동을 회전운동으로 전환시키는 크랭크샤프트가 장착되어 있는바, 즉 제2도에 도시된 것과 같이 실린더블럭(1)의 하부에 형성된 하부크랭크케이스(1a)와 오일팬(2) 사이에 베링캡을 매개로 지지된 2개의 분할베어링(3)에 크랭크샤프트가 끼워져 지지되게 되어 있다.A crankshaft is mounted between the cylinder block and the oil pan to connect the piston reciprocating in the cylinder block to convert the linear reciprocating motion of the piston into a rotational motion, ie, as shown in FIG. The crankshaft is fitted to the two split bearings 3 supported by the bearing caps between the lower crankcase 1a and the oil pan 2 formed in the lower portion of the cylinder block 1.
그런데 상기한 실린더블럭(1)과 오일팬(2)의 취부구조에서는 제2도에서 화살표로 도시된 것과 같이, 2개로 분할된 베어링(3)의 양쪽 선단부(3a)가 엔진의 횡진동방향(A)으로 배치되어 있기 때문에 베어링(3)의 양쪽 선단부(3a)에 집중적으로 충격이 가해지고, 이 때문에 베어링(3)의 양쪽 선단부(3a)가 다른 부위보다 먼저 마모되어 편마모가 발생하게 됨으로써 베어링(3)의 수명이 짧아지게 된다고 하는 결점이 있었다.However, in the above-described mounting structure of the cylinder block 1 and the oil pan 2, as shown by arrows in FIG. 2, both front end portions 3a of the bearing 3 divided into two are lateral vibration directions of the engine ( Since it is arranged in A), the impact is concentrated on both tip portions 3a of the bearing 3, which causes both of the tip portions 3a of the bearing 3 to wear out earlier than other portions, resulting in uneven wear. There existed a fault that the life of (3) was shortened.
이에 본 고안은 상기한 실린더블럭과 오일팬 사이에 장착되는 크랭크 샤프트용 베어링이 편마모되는 것을 방지하기 위해 안출된 것으로, 2개로 분할된 베어링의 양쪽 선단부가 엔진의 횡진동방향으로 배치되지 않도록 함으로써 베어링에 편마모가 일어나지 않도록 된 실린더블럭과 오일팬의 취부구조를 제공함에 그 목적이 있다.The present invention is designed to prevent the crankshaft bearing mounted between the cylinder block and the oil pan to be unweared, so that the two ends of the two-part bearings are not disposed in the transverse vibration direction of the engine. The purpose is to provide a mounting structure of the cylinder block and oil pan to prevent uneven wear in the tank.
상기한 바의 목적을 달성하기 위한 본 고안은, 실린더블럭의 하부크랭크케이스의 하면과 오일팬의 상면이 밀착되어 체결되면서 이 하부크랭크케이스와 오일팬 사이에 크랭크샤프트용 베어링이 끼워지되, 상기 하부크랭크케이스의 하면과 오일팬의 상면이 각각 실린더블럭의 횡진동방향에 대해 경사진 경사면을 이루도록 되어 있다.The present invention for achieving the object of the above bar, while the lower surface of the lower crankcase of the cylinder block and the upper surface of the oil pan is in close contact with the crankshaft bearing is inserted between the lower crankcase and the oil pan, the lower The lower surface of the crankcase and the upper surface of the oil pan each form an inclined surface inclined with respect to the lateral vibration direction of the cylinder block.
이에 따라 실린더블럭과 오일팬 사이에 삽입되는 크랭크샤프트용 베어링의 양쪽 선단부가 엔진의 횡진동방향에 대해 경사지게 위치되어 이 부분이 편마모되는 것을 방지할 수 있게 된다.Accordingly, both ends of the crankshaft bearing inserted between the cylinder block and the oil pan are inclined with respect to the transverse vibration direction of the engine, thereby preventing the portion from being unevenly worn.
이하 본 고안을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도(a)는 본 고안의 1실시예에 따라 실린더블럭에 오일팬이 취부된 상태의 개략적인 단면도인 바, 즉 실린더블럭(1)의 하부크랭크케이스(1a)의 하면이 한쪽 선단부에서 다른쪽 선단부까지 소정각도로 경사지게 형성되어 경사면(1b)을 이루고, 이 경사면(1b)과 밀착되어 보울트로 체결되는 오일팬(2)의 상면도 대응되도록 경사지게 형성되어 경사면(2a)을 이루는 구조로 되어 있다.FIG. 1 (a) is a schematic cross-sectional view of a state in which an oil pan is mounted on a cylinder block according to an embodiment of the present invention, that is, a lower surface of the lower crankcase 1a of the cylinder block 1 is disposed at one tip portion. It is formed to be inclined at a predetermined angle to the other front end to form an inclined surface (1b), the upper surface of the oil pan (2) that is in close contact with the inclined surface (1b) fastened by a bowl is formed to be inclined so as to correspond to the inclined surface (2a) It is.
이에 따라 상기 실린더블럭(1)과 오일팬(2) 사이의 삽입구멍에 삽입되는 크랭크샤프트용 분할베어링(3)의 양쪽 선단부(3a)는 엔진의 횡진동방향(A)에 대해 각각 소정각도 만큼씩 상하로 경사지게 위치되어, 엔진이 화살표 방향(A)으로 진동을 하게 되더라도 그 진동방향의 충격하중을 양쪽 선단부(3a)가 직접적으로 받지 않게 됨으로써, 이 양쪽 선단부(3a)가 다른 부위보다 빨리 마모되는 것을 방지하여 베어링이 수명이 짧아지거나 하는 일이 없게 된다.As a result, both tip portions 3a of the crankshaft split bearing 3 inserted into the insertion hole between the cylinder block 1 and the oil pan 2 have a predetermined angle with respect to the transverse vibration direction A of the engine, respectively. When the engine vibrates in the direction of the arrow A, even if the engine vibrates in the direction of the arrow, the tip portions 3a are not directly received by both of the tip portions 3a, so that both tip portions 3a wear faster than the other portions. This prevents the bearing from shortening its lifespan.
한편 제1도(a)에서는 실린더블럭의 하면과 오일팬의 상면이 우측으로 경사지게 체결되어 있지만, 제1도(b)에 도시된 것과 같이 좌측으로 경사지게 체결하여도 동일한 효과를 얻을 수 있음은 물론이다.Meanwhile, although the lower surface of the cylinder block and the upper surface of the oil pan are fastened to the right side in FIG. 1 (a), the same effect can be obtained even if the screw block is inclined to the left side as shown in FIG. to be.
이상 설명한 바와 같이 본 고안에 따른 실린더블럭과 오일팬의 취부구조에 의하면, 실린더블럭의 하부크랭크케이스의 하면과 이 하면에 밀착되어 체결되는 오일팬의 상면이 엔진의 횡진동방향과 소정각도를 두고 경사지게 형성되어 체결됨에 따라 실린더블럭과 오일팬 사이에 삽입되는 크랭크샤프트용 베어링의 양쪽 선단부가 엔진의 횡진동방향에 대해 경사지게 위치되어 이 부분이 편마모되는 것을 방지할 수 있는 효과가 있다.As described above, according to the mounting structure of the cylinder block and the oil pan according to the present invention, the lower surface of the lower crankcase of the cylinder block and the upper surface of the oil pan tightly fastened to the lower surface have a predetermined angle with the lateral vibration direction of the engine. Both ends of the crankshaft bearing inserted between the cylinder block and the oil pan are inclined with respect to the transverse vibration direction of the engine as it is formed to be inclined and fastened, thereby preventing partial wear.
