Description
본 고안은 로커카바의 장착구조, 특히 캠축 등을 보호하기 위하여 실린더헤드에 로커카바를 체결시 밀봉을 위해 경계부에 개재되는 고무가스켓의 시일성 저하 방지를 위한 장치에 관한 것이다.The present invention relates to a device for preventing the deterioration of the sealability of the rubber gasket which is interposed at the boundary for sealing when the rocker cover is fastened to the cylinder head to protect the mounting structure of the rocker cover, especially the camshaft.
종래 실린더헤드(10)에 로커카바(11)를 볼트(12)체결하여 장착함에 있어서 도 2에 도시하는 것과 같이 양측부재의 접촉경계면에 가스 및 오일의 누설을 방지하기 위하여 가스켓(13)을 개재시켜 조립하고 있다.As shown in FIG. 2, when the rocker cover 11 is fastened to the cylinder head 10 by bolts 12, the gasket 13 is interposed to prevent leakage of gas and oil on the contact boundary surfaces of both members. I assemble it.
그런데 통상 밀봉력을 높이기 위해서는 고무재질의 가스켓을 사용하여 볼트(12) 체결시 압축 변형토록 하므로써 고무가스켓(13)의 탄성력에 의해 시일성을 유지하고 있다.However, in order to increase the sealing force, the sealing force is maintained by the elastic force of the rubber gasket 13 by compressing and deforming when the bolt 12 is fastened using a rubber gasket.
또한 볼트(12)의 조임 탄성력의 유지를 위해 고무탄성체(14)를 사용하고 있다. 그러나 상기한 고무가스켓(13)과 고무탄성체(14)는 시간이 경과함에 따라 고무가 경화되어 탄성력을 잃게 되므로써 장시간 사용할 때 시일성을 유지하기가 곤란하여 로커카바내의 오일과 가스가 누설되는 문제점이 있게 된다.In addition, the rubber elastic body 14 is used to maintain the tightening elastic force of the bolt 12. However, the rubber gasket 13 and the rubber elastomer 14 have a problem in that oil and gas in the rocker cover leak due to difficulty in maintaining the sealability when used for a long time because the rubber is hardened and the elastic force is lost as time passes. Will be.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 로커카바를 가스켓과 탄성체를 개재시켜 실린더헤드에 장착함에 있어서 장시간 사용하더라도 초기상태와 같은 탄성력을 유지하여 가스켓의 시일성능의 저하를 방지하는 구조의 로커카바의 장착구조를 제공하는 데 있다.The present invention has been proposed in view of the above problems, and its object is to provide a rocker cover with a gasket and an elastic body to the cylinder head to maintain the same elastic force as the initial state even if it is used for a long time. It is to provide a mounting structure of the rocker cover of the structure to prevent degradation.
상기한 목적을 달성하기 위한 본 고안은The present invention for achieving the above object
고무가스켓과 고무탄성체를 개재하여 실린더헤드에 볼트 체결하는 로커카바 장착구조에 있어서,In the rocker cover mounting structure that bolts to the cylinder head via a rubber gasket and a rubber elastic body,
상기 고무탄성체 몸체 내의 공간부에는 비압축성 유체가 충진되어 있는 것임을 특징으로 한다.The space in the rubber elastic body is characterized in that the incompressible fluid is filled.

※ 도면의 주요부분에 대한 부호의 설명※ Explanation of code for main part of drawing
1 : 로커카바 2 : 고무가스켓1: rocker cover 2: rubber gasket
3 : 볼트 4 : 실린더헤드3: bolt 4: cylinder head
5 : 고무탄성체 6 : 비압축성유체5: rubber elastomer 6: incompressible fluid
이하 본 고안의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 고안에 의한 로커카바 장착 구조를 나타내는 도면으로 로커카바(1)는 오일누설을 방지하기 위해 고무가스켓(2)을 개재하여 볼트(3)로 실린더헤드(4)에 장착된다.1 is a view showing a rocker cover mounting structure according to the present invention, the rocker cover 1 is mounted to the cylinder head (4) with a bolt (3) via a rubber gasket (2) to prevent oil leakage.
상기 볼트(3)를 체결함에 있어서는 로커카바(1)와의 사이에 고무탄성체(5)를 개재시켜 조립하고 있으며 고무탄성체(5)의 몸체내의 공간에는 비압축성유체(6), 예를 들면 오일이 충진되어 있다.In the fastening of the bolt 3, the rubber elastic body 5 is assembled between the rocker cover 1 and the space in the body of the rubber elastic body 5 is filled with an incompressible fluid 6, for example, oil. It is.
이와같은 구성에 의하면 볼트(3)를 체결할 때 고무가스켓(2)과 고무탄성체(5)가 적절한 탄성력을 갖도록 압축 변형되는 위치까지 조이게 되며 시간이 경과하여 고무가스켓(2)이 경화되어 탄성력을 상실하더라도(즉, 주저않게 됨) 고무탄성체(5)내에 충진된 오일이 팽출하여 유격분을 상쇄시켜주게 되어 초기 상태와 같은 강성(stiffness)을 유지하게 된다.According to such a configuration, when the bolt 3 is tightened, the rubber gasket 2 and the rubber elastic body 5 are tightened to a position where they are compressed and deformed to have an appropriate elastic force. As time passes, the rubber gasket 2 is hardened to provide elastic force. Even if it loses (ie, does not hesitate), the oil filled in the rubber elastic body 5 swells to offset the clearance and maintains the same stiffness as the initial state.
여기서 고무가스켓(2)보다 상대적으로 크기가 훨씬 큰 고무탄성체(5)에만 유체를 충진한 것으로 설명하였으나 고무가스켓(2) 몸체내에도 유체를 충진할 수 있음은 물론이다.Here, it is described that the fluid is filled only in the rubber elastic body 5 having a relatively larger size than the rubber gasket 2, but the fluid can be filled in the body of the rubber gasket 2.
이상과 같은 본 고안의 로커카바 장착구조에 의하면 볼트의 체결시 탄성력을 유지하기 위하여 적절한 힘으로 압축변형되는 고무탄성체내에 비압축성 유체를 충진하므로써 장시간 사용으로 인하여 고무가스켓이 경화하여 주저않더라도 유체의 팽출에 의해 유격량을 상쇄하게 되므로 가스켓의 시일성의 저하를 방지하는 효과가 있게 된다.According to the rocker cover mounting structure of the present invention as described above, in order to maintain the elastic force when the bolt is tightened, the inelastic fluid is filled in the rubber elastic body that is deformed by an appropriate force, so that the rubber gasket hardens due to long time use. As a result, the gap amount is canceled, thereby preventing the deterioration of the sealing property of the gasket.
