Description
본 발명은 배기밸브의 개폐를 조절하여 엔진의 압축비를 저하시킴으로서 엔진의 출력저하로 인한 제동효과를 얻도록 하는 차량의 배기밸브제어 엔진브레이크 장치에 관한 것이다.The present invention relates to an exhaust valve control engine brake apparatus for a vehicle for controlling the opening and closing of the exhaust valve to lower the compression ratio of the engine so as to obtain a braking effect due to a decrease in the output of the engine.
일반적으로 브레이크장치는 주행중의 자동차를 감속 또는 정치시킴과 동시에 주차상태를 유지하기 위하여 사용되는 장치이다. 이러한 브레이크장치의 용도에 따른 분류에는 주행중인 자동차를 감소시키거나 정지시에 사용되는 것으로서 브레이크페달을 밟아서 작용시키는 주 브레이크(풋 브레이크 또는 서비스 브레이크)와, 자동차를 주차상태로 유지하기 위한 주차브레이크(핸드 브레이크)가 있다.In general, a brake device is a device used to maintain a parking state while at the same time decelerating or standing a car while driving. According to the use of the brake device, the main brake (foot brake or service brake) which acts by depressing the brake pedal as being used at the time of reducing or stopping the vehicle and the parking brake for keeping the vehicle in the parking state ( Hand brake).
이러한 브레이크 중 주로 사용되는 주 브레이크는 유압에 의하여 힘을 전달하고 휠에 부착된 드럼이나 디스크를 압착하여 제동하는 유압브레이크가 일반적인바, 이는 내리막길 주행이나 잦은 급정거시 드럼에 무리가 가거나 슬립현상이 발생하게 되어 안전운행에 문제점이 있으며, 브레이크패드의 조기 마모로 인하여 수명이 감소되어 안전운행 및 경제성에 지장을 초래한다는 문제점이 있었다.The main brake used mainly among these brakes is a hydraulic brake that transmits force by hydraulic pressure and brakes a drum or a disk attached to the wheel. This is because a drum is excessively driven or slips when driving downhill or during frequent stops. There is a problem in the safe operation, the life is reduced due to premature wear of the brake pads, there was a problem that causes problems in the safe operation and economics.
이에 대하여 브레이크장치로서의 브레이크는 아니지만 차량의 마찰브레이크를 보호하고 제동효과를 높여서 긴 경사길을 내려갈 때나 고속주행시 감속하기 위하여 사용하는 브레이크로서 엔진의 압축압력을 높여서 제동력을 얻는 엔진브레이크를 사용하기도 하지만 그 사용이 용이하지 않아 운전경력이 많지 않은 운전자로서는 곤란함이 있다.On the other hand, it is not a brake as a brake device, but it is used to protect the friction brake of a vehicle and to increase the braking effect and to decelerate when driving down long slopes or at high speeds. This is not easy and it is difficult for the driver who does not have much driving experience.
본 발명은 상기한 제반 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 급정차나 내리막길 주행시 제동효과를 내도록 하여 주브레이크의 빈번한 사용으로 인한 패드 마모 등을 방지함과 동시에 확실한 제동효과를 낼 수 있도록 하며, 조작이 간편한 차량의 배기밸브제어 엔진브레이크 장치를 제공하는 데 있다.The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a braking effect during sudden stop or downhill driving, thereby preventing pad abrasion due to frequent use of the main brake, and at the same time producing a certain braking effect. To provide an easy to operate vehicle exhaust valve control engine brake device.

이하 첨부된 예시도면을 참조하여 본 발명의 바람직한 실시예를 보다 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명이 설치되는 엔진(E)에서의 적용부위를 간략하게 나타낸 도면으로서, 공기 및 혼합기가 유입되는 흡기관(21)을 개폐하는 흡기밸브(22)와, 배기 가스가 배기되는 배기관(23)을 개폐하는 배기밸브(24)가 캠(C)의 작동에 따라 구동되는 로커암(R)에 연결되어 있다. 미설명부호 '25'는 피스톤이다.FIG. 1 is a diagram briefly showing an application part in an engine E in which the present invention is installed, an intake valve 22 for opening and closing an intake pipe 21 through which air and a mixer are introduced, and an exhaust pipe through which exhaust gas is exhausted. An exhaust valve 24 which opens and closes 23 is connected to a rocker arm R which is driven by the operation of the cam C. Reference numeral 25 is a piston.
제3도는 제1도에서 배기밸브(24) 부위를 보다 상세히 나타낸 종래 구조로서, 캠(C)이 회전하여 로커암(R)의 축을 기준으로 상대적으로 반대편은 내려가게 되어 배기밸브(24)가 상하 구동되어 배기관(23)을 개폐하도록 되어 있는 구조이다. 미설명부호 'S'는 스프링이다.3 is a conventional structure showing the exhaust valve 24 in detail in FIG. 1, and the cam C rotates so that the opposite side is lowered relative to the axis of the rocker arm R so that the exhaust valve 24 It is a structure which is driven up and down to open and close the exhaust pipe 23. Unexplained symbol 'S' is a spring.
제2도는 본 발명의 구성을 나타낸 예시도로서, 제3도와 같은 구조의 배기밸브(24)에 상기 캠(C) 및 로커암(R)의 작동과는 별도로 배기밸브(24)를 상하 작동되도록 하는 밸브작동수단(10)을 설치한다. 이러한 밸브작동수단(10)은 상기 배기밸브(24)의 몸체 외주에 일체로 고정설치된 작동부재(11)와 이러한 작동부재(11)를 수용하며 일측에 오일의 압력이 공급되도록 통공(12a)이 형성된 하우징(12)으로 구성하는 것이 바람직한 바, 이에 한정하지 않으며 유압에 의해 구동하도록 하는 여러 가지 구조를 가질 수 있다.2 is an exemplary view showing the configuration of the present invention, the exhaust valve 24 of the structure shown in FIG. 3 so as to operate the exhaust valve 24 up and down separately from the operation of the cam (C) and rocker arm (R) Install the valve operating means 10 to. The valve operation means 10 accommodates the operation member 11 and the operation member 11 fixedly installed on the body outer periphery of the exhaust valve 24 and the through-hole 12a to supply the pressure of oil to one side It is preferable to configure the formed housing 12, but the present invention is not limited thereto, and may have various structures for driving by hydraulic pressure.
또한 상기 밸브작동수단(10)의 통공(12a)의 유압을 적절히 전달하도록 하는 콘트롤밸브(13)가 형성되며, 이러한 콘트롤밸브(13)의 작동을 제어하도록 ECU(14)와 연결되고, 이러한 ECU(14)는 운전석에 설치된 조작부(15)와 연결된다.In addition, a control valve 13 is formed to properly transmit the hydraulic pressure of the through hole 12a of the valve operating means 10, and is connected to the ECU 14 to control the operation of the control valve 13, such ECU 14 is connected to the operation unit 15 installed in the driver's seat.
한편 상기 콘트롤밸브(13)에 전달되는 오일은 오일펌프(도시하지 않음)로부터 공급받을 수 있도록 연결 형성함이 바람직하다.On the other hand, the oil delivered to the control valve 13 is preferably formed to be connected to be supplied from an oil pump (not shown).
이상과 같이 구성된 본 발명은 내리막길 주행 등과 같은 상황에서 운전자가 조작부(15), 예컨대 스위치를 작동시키면 ECU(14)를 통하여 콘트롤밸브(13)로 유압을 적절히 조절하여 상기 밸브작동수단(10)으로 보내게 된다. 이러한 유압에 따라 작동부재(11)가 하강하게 되면 이와 일체로 형성된 배기밸브(24)가 점선으로 도시한 위치까지 이동되어 열리게 된다. 따라서 배기밸브(24)의 간극(L)에 따라 엔진의 압축비가 저하되므로 엔진의 출력이 감소하게 되어 차량의 제동효과를 발생시키게 된다.According to the present invention configured as described above, when the driver operates the operation unit 15, for example, a switch in a downhill driving, the valve operating means 10 may be appropriately controlled by the control valve 13 through the ECU 14. Will be sent to. When the operation member 11 is lowered according to the hydraulic pressure, the exhaust valve 24 formed integrally therewith is moved to the position shown by the dotted line and opened. Therefore, since the compression ratio of the engine is lowered according to the gap L of the exhaust valve 24, the output of the engine is reduced, thereby causing a braking effect of the vehicle.
여기서, 배기밸브(24)가 하강되어 발생되는 전극(L)은 엔진의 폭발력 감소만을 유도할 수 있는 정도의 미소량으로써 엔진의 흡입-압축-폭발-배기로 이어지는 각 행정의 작동에는 지장을 주지 않는 범위내에서 단지 폭발력 저하만을 가져올 수 있는 간극(L) 만큼을 설계에 의해 하강시키는 것이다.Here, the electrode L generated when the exhaust valve 24 is lowered is a small amount that can only induce the reduction of the explosion force of the engine, which does not interfere with the operation of each stroke leading to the intake-compression-explosion-exhaust of the engine. The design is to lower as much as the gap L, which can bring about only the deterioration of the explosive force within the range.
따라서, 엔진이 꺼지거나 이상이 발생하지는 않고 엔진의 출력 저하에 의해 제동효과를 유도할 수가 있는 것이다.Therefore, the engine does not turn off or abnormality occurs, and the braking effect can be induced by the decrease in the output of the engine.
이상과 같은 본 발명은 차량의 제동에 있어서 그 조작이 간편하고 단순하여 용이하게 사용할 수 있다는 이점이 있으며, 위급시에 근본적인 제동효과를 가져올 수 있어서 차량의 안전성이 향상되고 이로 인하여 차량의 상품성을 향상시킬 수 있는 효과도 있다. 또한 급정차나 내리막길 주행시 제동효과를 내도록 하여 주브레이크의 빈번한 사용으로 인한 패드 마모 등을 방지하게 된다.The present invention as described above has the advantage that the operation in the braking of the vehicle is simple and simple to use easily, and can bring a fundamental braking effect in case of emergency improves the safety of the vehicle and thereby improves the merchandise of the vehicle There are also effects that can be made. In addition, it prevents pad wear due to frequent use of the main brake by making a braking effect during sudden stop or downhill driving.
