Description

디젤엔진의 일체형 밸브 브릿지Integrated valve bridge of diesel engine

본 고안은 디젤엔진에 있어서, 1개의 로커 아암에 의해 밸브를 2개씩 동시에 작동시키는 밸브 브릿지에 관한 것으로, 특히 밸브 브릿지를 로커아암에 일체로 형성하여 부품의 구성을 간략화하고 윤활유 공급이 필요없게 한 것이다.The present invention relates to a valve bridge for simultaneously operating two valves simultaneously by one rocker arm in a diesel engine. Particularly, the valve bridge is integrally formed on the rocker arm to simplify the construction of parts and eliminate the need for lubricant supply. will be.

4밸브식 디젤엔진의 경우에는 제2도의 도시와 같이 로커샤프트(1)에 축설된 로커 아암(2)의 일측 단부에 롤러(13)를 축설하고 그 하부에 밸브브릿지(15)를 당접시켜 그 밸브브릿지(15)의 저면에 2개의 밸브(6), (6')를 동시에 밀착시켜 윤활통로(12)에 의해 윤활유를 공급시켜 가며 반대측 롤러(3)를 캠(4)에 의해 작동시키므로 1개의 로커아암에 의해 동시에 밸브를 2개씩 작동하게 구성하였다.In the case of a four-valve diesel engine, as shown in FIG. 2, a roller 13 is arranged at one end of the rocker arm 2 built in the rocker shaft 1, and the valve bridge 15 is brought into contact with the bottom thereof. Since two valves 6 and 6 'are attached to the bottom of the valve bridge 15 at the same time, lubrication oil is supplied by the lubrication passage 12, and the opposite roller 3 is operated by the cam 4, so that 1 Two rocker arms were configured to operate two valves simultaneously.

전기한 종래의 벨브브릿지(15)는 이를 작동시키기 위해 타밸브에 의해 밸브브릿지(15)와 연접된 롤러(13)가 추가로 필요하고, 밸브브릿지(15)와 롤러(13)간에 마찰로 인한 소착현상을 막기 위해 윤활통로(12)를 형성하여 윤활유를 계속 공급하여야 되는 번거로움이 있고 그 추가구성의 필요성으로 구성이 복잡해지고 원가가 상승된 문제가 있다.The conventional valve bridge 15 described above additionally requires a roller 13 connected to the valve bridge 15 by another valve in order to operate the valve bridge 15, and due to friction between the valve bridge 15 and the roller 13 In order to prevent the ignition phenomenon, there is a problem in that the lubrication passage 12 is formed to continuously supply the lubricating oil, and the configuration is complicated and the cost is increased due to the need for the additional configuration.

실제로 작동중에 롤러(12)와 밸브브릿지(15)간에 소착현상이 발생하고 있다.In practice, sintering occurs between the roller 12 and the valve bridge 15 during operation.

본 고안은 밸브브릿지가 필요한 4밸브식 디젤엔진에 있어서, 전기한 문제점을 제거코저 추가 부품이나 윤활구성을 삭제하고 밸브브릿지를 로커아망의 일측 선단에 일체로 형성하여 구성의 간략화로 원가가 절감되고 윤활이 불필요하며 고장의 우려가 없는 일체형 밸브 브릿지를 제공함에 그 목적이 있다.The present invention eliminates the above-mentioned problems in the four-valve diesel engine requiring the valve bridge, eliminating the additional parts or lubrication structure, and forming the valve bridge integrally with one end of the rocker network to reduce the cost. Its purpose is to provide an integral valve bridge that does not require lubrication and does not have a risk of failure.

전기한 목적을 이루기 위한 기술적 수단으로 로커샤프트에 축설된 로커아암의 캠연접부 반대측 선단에 브릿지를 일체로 형성하고, 그 저면에 밸브를 당접되게 한 구성의 일체형 밸브브릿지를 제공한다.As a technical means for achieving the above object, a bridge is integrally formed at the distal end of the rocker arm opposite to the cam joint of the rocker shaft, and an integrated valve bridge having a structure in which a valve is abutted on the bottom thereof is provided.

이하, 그 실시예를 첨부도면에 의하여 상세히 설명한다.Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings.

제1도는 본 고안을 개략적으로 표시한 정면도이다.1 is a front view schematically showing the present invention.

로커샤프트(1)에 로커아암(2)을 축설하고, 일측단부의 롤러(3)를 캠(4)에 연접되게 한다.The rocker arm 2 is arranged on the rocker shaft 1 so that the roller 3 at one end thereof is connected to the cam 4.

로커아암(2)의 롤러(3)의 반대측 단부에 브릿지부(5)를 일체로 형성하고 그 저면에 밸브(6), (6')를 당접시킨다.The bridge part 5 is integrally formed in the opposite end part of the roller 3 of the rocker arm 2, and the valve 6 and 6 'are abutted on the bottom face.

도면중 미설명 부호 7은 스프링, 8은 실린더이다.In the drawings, reference numeral 7 denotes a spring and 8 denotes a cylinder.

이과 같이 된 본 고안의 작용을 설명한다.It explains the operation of the present invention made as described above.

엔진의 회전에 의해 타임벨트에 동력전달로서 캠샤프트가 회전하면서 캠(4)이 회전하게 되면 로커샤프트(1)에 축삽된 로커아암(2)이 그 선단의 롤러(3)에 의해 캠(4)과 연접되면서 샤프트(1)를 중심으로 상하 작동케 되어 그 브릿지부(5)가 롤러(3)의 이동 방향과 반대방향으로 상하 운동하면서 밸브(6), (6')를 상하 작동케 한다.When the cam 4 rotates while the cam shaft rotates as a power transmission to the time belt by the rotation of the engine, the rocker arm 2 inserted into the rocker shaft 1 is cam 4 by the roller 3 at its tip. ) Is operated up and down about the shaft (1) while being in contact with the) so that the bridge portion (5) moves up and down in the direction opposite to the movement direction of the roller (3) to operate the valve (6), (6 ') up and down. .

이때 브릿지부(5)가 로커아암(2)과 일체로 형성되어 있으므로 마찰작용이 없어 별도의 윤활작용이 필요없이 윤활구성이 삭제될 수 있다.At this time, since the bridge portion 5 is integrally formed with the rocker arm 2, there is no friction action so that the lubrication configuration can be deleted without the need for a separate lubrication action.

또 마찰을 위한 롤러 역시 제거되어 그 구성이 간략화되므로서 원가가 절감되고 고장의 우려가 없는 것이다.In addition, the roller for friction is also removed, the configuration is simplified to reduce the cost and there is no fear of failure.

이상과 같이 본 고안은 브릿지를 로커아암의 선단에 일체로 구성하므로서 로러 한개가 제거되고 별도의 밸브 브릿지가 필요없으며 로커아암에 대한 윤활 통로의 가공이 불필요하여 원가가 절감되고 소착등 고장의 우려가 없는 효과가 있다.As described above, the present invention constitutes a bridge integrally with the tip of the rocker arm, thereby eliminating one roller and eliminating the need for a separate valve bridge. There is no effect.
