Description
본 고안은 밸브 트레인(Valve Train) 구조에서 로커 암 샤프트를 센터에서 견고하게 고정되도록 하여 밸브 구동이 안정화될 수 있도록 하는 로커 암 샤프트 지지구조에 대한 것이다.The present invention relates to a rocker arm shaft support structure that allows the rocker arm shaft to be firmly fixed at the center in the valve train structure so that the valve drive can be stabilized.
현재 자동차 엔진의 밸브 트레인 구조는 캠 샤프트의 구동에 의해 로커 암을 요동시키므로서 상기 로커 암에 의해서 밸브가 작동되도록 하는 구조가 일반적이다.Currently, the valve train structure of an automobile engine is generally a structure in which a valve is operated by the rocker arm by rocking the rocker arm by driving the cam shaft.
상기와 같은 밸브 트레인 구조는 도 2에서와 같이 캠축에 대하여 양측으로 평행하게 축설시킨 로커 암 샤프트(4)를 캠축을 커버하는 캠 캡(5)을 관통하여 볼트 체결에 의해서 실린더 헤드(7)에 고정토록 하고 있다.The valve train structure as described above has a rocker arm shaft 4 arranged parallel to both sides of the cam shaft as shown in FIG. 2 through the cam cap 5 covering the cam shaft and bolted to the cylinder head 7. It is fixed.
상기한 로커 암 샤프트(4)에는 보통 다수개의 로커 암이 축설되어 일단은 캠에 접촉되고, 타단은 밸브 스탬 상단부에 접촉하여 캠축 구동에 따라 밸브를 승강작동시키게 된다.The rocker arm shaft 4 is usually provided with a plurality of rocker arms, one end is in contact with the cam, the other end is in contact with the upper end of the valve stem to raise and lower the valve in accordance with the camshaft drive.
이렇게 로커 암의 작동을 지지하게 되는 로커 암 샤프트(4)는 구동력 전달과정에서 대단히 큰 충격이 가해지게 되므로 최근에는 캠 캡(5)의 상부면으로 로커 암 샤프트(4)가 안착되도록 하는 반원형 가이드(6)가 돌설되도록 하여 지지되도록 하고 있다.Since the rocker arm shaft 4 supporting the operation of the rocker arm is subjected to a very large impact in the process of transmitting the driving force, a semicircular guide for allowing the rocker arm shaft 4 to rest on the upper surface of the cam cap 5 recently. (6) is to be supported so that it is bulge.
하지만 상기와 같은 구조에서 로커 암 샤프트(4)의 고정 결착력은 단순히 로커 암 샤프트(4) 외주면 상단부로부터 실린더 헤드(7)로 체결되는 볼트(9) 체결력에 의해서 유지가 되므로 캠축으로부터의 구동력을 밸브에 전달하는 과정에서 발생되는 강한 충격으로 로커 암 샤프트(4)의 체결력이 약화되면서 미세하게 유동하게 되는 단점이 있다.However, in the structure as described above, the fixed fastening force of the rocker arm shaft 4 is simply maintained by the fastening force of the bolts 9 fastened to the cylinder head 7 from the upper end of the outer circumferential surface of the rocker arm shaft 4, thereby driving the driving force from the camshaft. Due to the strong impact generated in the process of transmitting to the weakening force of the rocker arm shaft 4 there is a disadvantage that the fine flow.
이같은 유동은 곧바로 엔진의 밸브 작동에 영향을 미쳐 밸브의 불안정한 작동을 초래하게 되는 문제가 있게 된다.This flow has a problem that immediately affects the valve operation of the engine resulting in unstable operation of the valve.
이에 본 고안은 상기한 단점과 문제점을 개선시키기 위하여 캠 캡(1)의 형상을 로커 암 샤프트 외주면 전체를 감싸는 형상으로 되도록 하되 일측으로는 각각 슬롯 홀을 천공시켜 볼트 체결시 상기 슬롯 홀의 간격이 좁혀지면서 로커 암 샤프트의 지지력을 증강시켜 안정된 밸브 작동을 제공코자 하는데 본 고안의 목적이 있다.In order to improve the above-mentioned disadvantages and problems, the present invention is designed so that the shape of the cam cap 1 covers the entire outer circumference of the rocker arm shaft, but the slot holes are narrowed to one side to narrow the gap between the slot holes during bolting. The purpose of the present invention is to provide a stable valve operation by increasing the bearing capacity of the rocker arm shaft.
상기한 목적을 달성시키기 위한 본 고안의 수단으로 실린더 헤드 상부로 얹혀지는 캠 캡을 상부로 연장시켜 양측으로는 로커 암 샤프트의 외주면이 완전히 감싸지도록 하는 삽입홀을 형성하고, 상기 양측 삽입홀의 일측으로는 외주면측으로 연통되도록 하는 소폭의 슬롯홀이 형성되도록 하는 구성을 특징으로 한다.As a means of the present invention for achieving the above object by extending the cam cap to be mounted on top of the cylinder head to form an insertion hole to completely surround the outer circumferential surface of the rocker arm shaft on both sides, to one side of the insertion hole Is characterized in that the configuration is such that a narrow slot hole is formed to communicate with the outer peripheral surface side.

7 : 실린더 헤드7: cylinder head
이를 첨부한 실시예 도면을 참조하여 설명하면 도 1은 본 고안에 따른 캠 캡의 구조를 도시한 것으로서, 본 고안은 캠 캡(1)의 상부를 로커 암 샤프트(4)의 외주면이 일정 두께로 감싸지도록 연장하고, 연장된 부위의 양측으로는 로커 암 샤프트(4)가 축설되도록 삽입홀(2)을 천공하며, 상기 삽입홀(2)의 일측은 외주면측으로 연통되도록 하는 슬롯홀(3)이 형성되도록 한 구조이다.1 illustrates the structure of a cam cap according to the present invention, the present invention has an outer circumferential surface of the rocker arm shaft 4 having a predetermined thickness at an upper portion of the cam cap 1. It extends so as to be wrapped, and drills the insertion hole (2) so that the rocker arm shaft (4) is arranged on both sides of the extended portion, one side of the insertion hole (2) is in communication with the outer peripheral surface side It is a structure to be formed.
특히 상기한 슬롯홀(3)은 소폭의 장공 형상으로 형성되도록 하며, 수평의 센터에 하나를 형성시킬 수도 있고, 센터 상하부로 각각 2개씩 형성되게 할 수도 있다.In particular, the slot hole 3 may be formed in a narrow long hole shape, and may be formed in one horizontal center, or two in the upper and lower centers.
상기한 캠 캡(1)은 실린더 헤드(7)의 캠 샤프트 보어(8)에 캠 샤프트를 안착시킨 상태에서 그 상부로 안착이 될 수 있도록 하는 것인바 이렇게 안착된 캠 캡(1)의 양측 삽입홀(2)로 각각 로커 암 샤프트(4)를 끼우고, 상기 양측 삽입홀(2) 수직 센터의 직상부로부터 볼트(9)를 체결하여 캠 캡(1)과 로커 암 샤프트(4)를 실린더 헤드(7)에 고정 결착되도록 한다.The cam cap (1) is to be seated on the cam shaft bore (8) of the cylinder head (7) to the upper portion of the cam shaft to be seated on both sides of the cam cap (1) so inserted The rocker arm shafts 4 are respectively inserted into the holes 2, and the cam cap 1 and the rocker arm shafts 4 are fastened by fastening bolts 9 from the upper portions of the vertical centers of the two insertion holes 2, respectively. It is fixed to the head (7).
이같은 볼트(9) 체결시 상부로부터 가해지는 체결압에 의해 캠 캡(1) 상부가 눌려지면서 삽입공(2)의 일측으로 천공시킨 슬롯홀(3)의 공간 폭은 점차 축소가 되는 동시에 삽입공(2)의 직경을 축소시키게 되므로서 삽입공(2) 내주면과 로커 암 샤프트(4)의 외주면간 밀착력이 대단히 견고해지게 된다.When the bolt 9 is fastened, the upper part of the cam cap 1 is pressed by the fastening pressure applied from the upper side, and the space width of the slot hole 3 drilled to one side of the insertion hole 2 gradually decreases, and at the same time, the insertion hole As the diameter of (2) is reduced, the adhesion between the inner circumferential surface of the insertion hole 2 and the outer circumferential surface of the rocker arm shaft 4 becomes very firm.
상기와 같은 로커 암 샤프트(4)의 고정은 지지하게 되는 면압을 확장시키게 되어 로커 암 샤프트(4)의 유동을 완전히 봉쇄시키게 되므로 로커 암에 의한 구동력 전달과정에서의 강한 충격으로 인한 로커 암 샤프트(4)의 장착 위치가 불변하면서 항상 센터의 정위치로 유지시킬 수가 있도록 한다.Locking the rocker arm shaft 4 as described above expands the surface pressure to be supported to completely block the flow of the rocker arm shaft 4, so that the rocker arm shaft due to a strong impact in the process of transmitting the driving force by the rocker arm ( The mounting position of 4) is unchanged, so that it can always be kept in the center position.
한편 상기 캠 캡(1)은 종래에 비해 강성이 가장 취약한 캠 샤프트의 센터 직상부의 두께를 견고하게 형성시키게 되어 보강 효과도 있게 된다.On the other hand, the cam cap (1) is to form the thickness of the upper portion of the center of the cam shaft of the cam shaft that is weakest rigidity compared with the prior art, there is also a reinforcing effect.
따라서 본 고안은 간단한 캠 캡(1)의 구조 및 로커 암 샤프트(4)의 체결 구조 개선으로 로커 암 샤프트(4)를 더욱 견고하게 지지시키게 되므로 안정된 밸브 작동을 제공하게 되는 동시에 특히 캠 샤프트 구동에 따른 캠 캡(1)의 변형을 방지시키게 되어 엔진의 구동성을 안정화시키게 되는 매우 유용한 효과가 있도록 하는 것이다.Therefore, the present invention supports the rocker arm shaft 4 more firmly by improving the structure of the simple cam cap 1 and the fastening structure of the rocker arm shaft 4, thereby providing stable valve operation and at the same time especially in driving the cam shaft. It is to prevent the deformation of the cam cap 1 according to the very useful effect of stabilizing the driveability of the engine.
