Description
본 고안은 자동차용 엔진의 헤드볼트구조에 관한 것으로, 특히 헤드볼트의 중앙부를 관통하여 중공부를 형성시켜 별도의 기존의 오일리턴홀을 대용하도록된 자동차용 엔진의 헤드볼트구조에 관한 것이다.The present invention relates to a head bolt structure of an automotive engine, and more particularly, to a head bolt structure of an automotive engine configured to replace a conventional oil return hole by forming a hollow through a central portion of the head bolt.
일반적으로, 자동차의 실린더헤드부에는 종래구조로 도시된 도 4에 예시된바와같이, 상부에는 실린더헤드와, 실린더블럭 및 오일팬으로 구성되어져 피스톤 및 캠샤프트가 작동할 수 있도록 되며 또한 가열되어진 윤활유가 오일팬으로 회수되도록 실린더헤드 및 실린더블럭에 별도의 오일리턴홀이 각각 편성되어지는 외에도 헤드볼트홀(Head-Bolt-Hole) 및 워트쟈켓(Water-Jacket)이 가공되어진다.In general, the cylinder head portion of the vehicle, as shown in Figure 4 shown in a conventional structure, the upper portion is composed of a cylinder head, a cylinder block and an oil pan to operate the piston and camshaft and also heated lubricant In addition to the separate oil return holes are arranged in the cylinder head and the cylinder block so that the oil is recovered to the oil pan, a head bolt hole and a water jacket are processed.
따라서, 오일이 각부에 공급되어 윤활되어지고 윤활작용이 끝난 잔류오일이 실린더헤드에 가공되어진 오일리턴구조를 통과하면서 실린더블럭을 통과함으로서 오일팬에 회수되어진다.Therefore, the oil is supplied to each part and lubricated, and the lubricated residual oil is recovered to the oil pan by passing through the cylinder block while passing through the oil return structure processed in the cylinder head.
그러나, 상기 오일리턴구조는 실린더헤드 및 실린더블럭 각각에 별도의 오일리턴홀을 가공함으로서 실린더헤드부 설계시 차지하는 공간이 커지고 한공정이 추가되어져 가공설비가 증가되는 문제점이 있었다.However, the oil return structure has a problem in that processing space is increased by processing a separate oil return hole in each of the cylinder head and the cylinder block to increase the space occupied in the design of the cylinder head portion, and a process is added.
이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로서, 실린더헤드부 가공의 한공정인 헤드볼터홀가공에 볼트의 중앙부를 관통함으로서 잔류 오일이 관통된 볼트중심부를 통과할 수 있도록 되어 별도의 오일리턴홀을 가공하는 공정을 폐지할 수 있는 자동차용 엔진의 헤드볼트구조를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and penetrates the center portion of the bolt to the head bolter hole processing, which is a process of processing the cylinder head, so that the remaining oil can pass through the center of the bolt through which the remaining oil passes. It is an object of the present invention to provide a head bolt structure of an automotive engine capable of abolishing a process of processing a return hole.

2a:오일리턴홀2a: oil return hole
상기와 같은 목적을 달성하기 위한 본 고안은, 헤드볼트의 길이방향의 중심부가 원형으로 관통되어 중공부로 형성되고 상기 중공헤드볼트를 수용가능한 암나사부로 형성된 중공부가 실린더 및 실린더블럭에 각각 관통되어지고 상기 실린더블럭의 나사부의 끝단은 저면부의 주조된 중공부의 상단부와 맞닫으므로 소정의 형상으로 관통연결되어지게 된다.The present invention for achieving the above object, the central portion in the longitudinal direction of the head bolt is formed through the hollow portion and the hollow portion formed by the female screw portion that can accommodate the hollow head bolt is penetrated through the cylinder and the cylinder block, respectively, The end of the threaded portion of the cylinder block is in contact with the upper end portion of the cast hollow portion of the bottom portion so that it is connected through a predetermined shape.
따라서, 오일이 실린더헤드부에 공급되어 각부로 윤활되어져 윤활작용을 실시하게되고, 상기의 윤활작용이 끝난 잔류오일은 상기 중공헤드볼트의 관통된 중공부를 통과하여 실린더블럭의 상단의 중공부를 통과하여 오일팬으로 회수되어진다.Therefore, the oil is supplied to the cylinder head part and lubricated to each part to perform lubrication, and the residual lubricating oil passes through the hollow part of the hollow head bolt and passes through the hollow part of the upper end of the cylinder block. Recovered to oil pan.
이하, 본 고안을 예시된 도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the illustrated drawings.
도 1은 본 고안에 따른 실린더헤드부를 도시한 것이고, 도 2는 본 고안에 따른 도 1의 I-I선의 요부단면을 도시한 것이며, 도 3은 본 고안에 따른 도 2의 A부를 상세하게 도시한 것인바, 본 고안은, 통상적으로 이루어진 실린더헤드(1)내에 암나사산으로 가공된 볼트홀이 관통되어지고 상기 볼트홀과 결합되어지는 헤드볼트(1a)의 중심부가 관통되어져 중공부(1b)로 형성되어지고, 상기 실린더헤드의 하면부에 연결되어지는 실린더블럭(2)이 상기 볼트홀과 일치되어 연결되도록 암나사산으로 가공되어져 볼트홀로 이루어지며 이때 실린더블럭(2)의 상단은 볼트홀에 의해서 관통되어진다.1 is a view showing a cylinder head portion according to the present invention, Figure 2 is a sectional view of the main portion of the line II of Figure 1 according to the present invention, Figure 3 is a detailed view of the portion A of Figure 2 according to the present invention Invar, the present invention, the bolt hole processed with a female thread in the cylinder head (1) made in a conventional manner is passed through the central portion of the head bolt (1a) coupled to the bolt hole is formed as a hollow portion (1b) The cylinder block 2, which is connected to the lower surface of the cylinder head, is machined with a female thread to be connected to the bolt hole to be connected to the bolt hole, and the upper end of the cylinder block 2 is penetrated by the bolt hole. It is done.
따라서, 상기 중공헤드볼트(1a)는 실린더헤드의 관통된 볼트홀을 통과하여 상기 볼트홀과 일치하는 실린더블럭(2)의 볼트홀을 통과하여 실린더헤드(1)와 실린더블럭(2)은 결합되어진다.Therefore, the hollow head bolt 1a passes through the bolt hole of the cylinder head and passes through the bolt hole of the cylinder block 2 corresponding to the bolt hole, so that the cylinder head 1 and the cylinder block 2 are coupled to each other. It is done.
이에따라, 상기 실린더헤드(1)와 실린더블럭(2)은 중공헤드볼트(1a)를 매개로 소정형상의 관통된 중공부를 형성하게 되고 실린더내에 공급되어진 오일이 각부로 윤활되어져 윤활작용이 끝난 잔류오일은 상기 관통되어진 중공부를 통과하여 실린더블럭(2)의 상단의 중공부를 통과하여 오일팬(3)으로 회수되어진다.Accordingly, the cylinder head 1 and the cylinder block 2 form a penetrated hollow portion of a predetermined shape through the hollow head bolt 1a, and the oil supplied into the cylinder is lubricated to each portion, and the remaining oil is lubricated. Is passed through the hollow portion through the hollow portion of the upper end of the cylinder block (2) is recovered to the oil pan (3).
이상 설명한 바와 같이 본 고안에 의하면, 헤드볼트의 중심부에 중공부를 형성하여 잔류오일의 통로로 이용함에 따라 실린더헤드 및 실린더블럭의 각각에 오일리턴홀을 폐지하여 가공경비를 줄일 수 있고 실린더헤드부의 폭을 줄일 수 있으므로 제품의 경량화 및 설계공간설정이 용이해지며 또한 기존의 오일리턴홀의 수보다 다수의 중공헤드볼트를 통하여 오일리턴성능이 향상되어지는 효과가 있다.As described above, according to the present invention, as the hollow part is formed in the center of the head bolt and used as a passage for residual oil, the oil return hole is closed in each of the cylinder head and the cylinder block to reduce the processing cost and the width of the cylinder head part. Since it is possible to reduce the weight of the product and set the design space, it is also possible to improve the oil return performance through the number of hollow head bolts than the number of existing oil return holes.
이상에서 설명한 것은 본 고안에 의한 자동차용 엔진의 헤드볼트구조를 실시하기위한 하나의 실시예에 불과한 것으로, 이하 청구범위내에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변경실시가 가능할 것이다.What has been described above is only one embodiment for implementing the head bolt structure of the engine for automobiles according to the present invention, it is common in the field to which the subject innovation belongs without departing from the gist of the subject innovation claimed in the following claims. Anyone with knowledge will be able to make various changes.
