본 발명은 브레이크 장치의 매스터실린더에 연결되어 작은 조작력으로 큰 구동력을 얻도록 하는 매스터백에 관한 것으로서, 특히 과급기관에 사용되는 매스터백의 전체 작동구조를 단순화하여 원가가 저감되도록 하는 자동차 브레이크의 매스터백 작동구조에 관한 것이다.The present invention relates to a master bag connected to the master cylinder of the brake device so as to obtain a large driving force with a small operating force. In particular, a master bag of an automobile brake for simplifying the overall operating structure of the master bag used in the turbocharger to reduce the cost It relates to the working structure.
종래 자동차 매스터백의 작동구조는, 제1도에 도시되는 바와같이, 브레이크장치의 매스터실린더(master cylinder)(10)와 연동되게 연결되는 매스터백(master vac.)(20)이 설치되고, 매스터백(20)에 구동 가능하게 연결되는 작동로드(21)가 대쉬판넬(도시생략)을 관통하여 운전석에 설치되는 브레이크페달(22)에 조작 가능하게 연결되어 있다. 한편, 매스터백(20)은 원통형 실린더로 형성되고, 내부에 작동로드(21)와 연동되는 슬라이더(23)가 실린더 내주면에 기밀하게 장착되며, 매스터 실린더(10)와 슬라이더(23)사이의 실린더에 기관의 흡기관에 연통되는 진공파이프라인(24)이 연통되어 있다.As shown in FIG. 1, the operation structure of a conventional automobile master bag is provided with a master vac. 20 connected in cooperation with a master cylinder 10 of a brake device. An actuating rod 21 operatively connected to 20 is operably connected to a brake pedal 22 installed in a driver's seat through a dash panel (not shown). Meanwhile, the master bag 20 is formed of a cylindrical cylinder, and a slider 23 interlocked with the operation rod 21 is hermetically mounted on the inner circumferential surface of the cylinder, and a cylinder between the master cylinder 10 and the slider 23 is provided. The vacuum pipe line 24 communicates with the intake pipe of the engine.
이와 같이 구성되는 종래 자동차 매스터백의 작동구조는, 기관의 흡기관에 작용되는 부압이 진공파이프라인(24)을 통해 매스터백(20)의 일측 실린더 내부에 작용되어, 일정한 진공압이 슬라이더(23)를 당기기 때문에, 작동로드(21)를 통해 매스터실린더(10)를 가압시키기 위한 필요 조작력이 저감되도록 하므로, 운전자가 작은 조작력으로 브레이크페달(22)을 조작하여도 매스터실린더(10)의 작동이 원활하도록 한다.In the operation structure of the conventional automobile master bag configured as described above, the negative pressure acting on the intake pipe of the engine is applied to one cylinder of the master bag 20 through the vacuum pipe line 24, so that the constant vacuum pressure is applied to the slider 23. Since the required operating force for pressurizing the master cylinder 10 through the operating rod 21 is reduced, the operation of the master cylinder 10 is smooth even if the driver operates the brake pedal 22 with a small operating force. Do it.
그러나, 과급기관의 경우 기관의 흡기관을 연통시켜 진공압을 사용하는데 있어서, 비교적 진공압이 낮기 때문에 별도의 진공펌프를 연결시켜 매스터백(20)에 작용되는 진공압이 일정 부압을 유지하도록 하고 있다.However, in the case of the supercharged engine, the intake pipe of the engine communicates with each other so that the vacuum pressure is relatively low, so that a separate vacuum pump is connected so that the vacuum pressure applied to the master bag 20 maintains a constant negative pressure. have.
이로인해 작동구조가 복잡해지고, 생산원가가 상승되는 문제점이 있었다.As a result, the operation structure is complicated, and there is a problem that the production cost is increased.
본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위해, 과급장치의 과급압이 매스터백의 실린더 뒤쪽에 연통되도록하여, 과급압이 슬라이더 뒤쪽에 미는 힘으로 작용되도록하여, 매스터백의 조작력이 저감되도록 하고, 전체 작동구조가 단순하도록 하는 과급기관의 자동차 브레이크의 매스터백 작동구조를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, so that the boost pressure of the supercharger is communicated to the rear of the cylinder of the master bag, so that the boost pressure acts as a force pushing the rear of the slider, so that the operation force of the master bag is reduced In addition, the present invention provides a masterback operation structure of a vehicle brake of a turbocharger, which makes the entire operation structure simple.
이하 첨부된 도면에 의하여 본 발명의 기술적 사상을 상세히 설명하면 다음과 같다.Hereinafter, the technical spirit of the present invention will be described in detail with reference to the accompanying drawings.
본 발명 매스터백의 작동구조도 제2도에 도시되는 바와같이, 브레이크장치의 매스터실린더(10)와 연동되게 연결되는 매스터백(20)이 설치되고, 매스터백(20)이 설치되고, 매스터백(20)에 구동 가능하게 연결되는 작동로드(21)가 브레이크페달(22)에 조작 가능하게 연결되며, 매스터백(20)이 원통형 실린더로 형성되고, 내부에 작동로드(21)와 연동되는 슬라이더(23)가 실린더 내주면에 기밀하게 장착되는 것은 종래와 같다. 단, 본 발명은 슬라이더(23)와 브레이크페달(22)쪽 사이의 매스터백(20)실린더의 타측 내부에 기관 과급장치의 과급압이 과급파이프라인(25)을 통해 연통됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 2, the operation structure of the master bag of the present invention is provided with a master bag 20 which is connected to the master cylinder 10 of the brake device, a master bag 20 is installed, and a master bag ( An actuating rod 21 operably connected to the 20 is operably connected to the brake pedal 22, the master bag 20 is formed of a cylindrical cylinder, and a slider interlocked with the actuating rod 21 therein ( It is conventional that 23 is hermetically mounted on the inner circumferential surface of the cylinder. However, the present invention is based on the technical configuration that the boost pressure of the engine turbocharger is communicated through the boost pipeline 25 inside the cylinder of the master bag 20 between the slider 23 and the brake pedal 22 side. It features.
이와 같이 구성되는 본 발명은, 기관의 터보장치에서 과급압이 과급파이프라인(25)을 통해 매스터백(20)의 실린더로 연통되어, 실린더 후부쪽에서 작동로드(21)와 연동되는 슬라이더(23)에 일정한 미는 힘으로 작용되도록 하기 때문에, 작동로드(21)를 통해 매스터실린더(10)를 가압시키기 위한 필요 조작력이 저감되도록 하므로, 운전자가 작은 조작력으로 브레이크페달(22)을 조작하여도 매스터실린더(10)의 작동이 원활하도록 한다.According to the present invention configured as described above, the slider 23 in which the turbo pressure of the engine communicates with the cylinder of the master bag 20 through the turbopipe line 25 and is interlocked with the operating rod 21 at the rear of the cylinder. Since a predetermined pushing force is applied, the required operating force for pressurizing the master cylinder 10 through the operating rod 21 is reduced, so that even if the driver operates the brake pedal 22 with a small operating force, the master cylinder ( 10) Make the operation smooth.
한편, 이러한 본 발명은 과급장치의 과급압이 기관의 흡기관에 연통되는 전공 압력에 의해 비교적 크기 때문에, 진공펌프와 같은 별도의 부가장치 없이 매스터백(20)의 원활한 조작이 가능하도록하여, 전체적인 작동구조가 간단하도록 하므로, 생산원가가 저감되도록 하는 효과가 있다.On the other hand, the present invention, since the boost pressure of the supercharger is relatively large by the pressure of the air communicating with the intake pipe of the engine, it is possible to smoothly operate the master bag 20 without an additional device such as a vacuum pump, Since the operation structure is simplified, there is an effect that the production cost is reduced.
이상에서 살펴본 바와 같이, 본 발명은 과급장치의 과급압이 매스터백의 뒤쪽에서 슬라이더를 밀도록 장치되어, 매스터백의 조작력이 저감되도록 하고, 전체 작동구조가 단순하도록하여 제작원가가 저감되도록 하는 매우 유용한 것이다.As described above, the present invention is very useful for the boosting pressure of the supercharger to push the slider at the back of the master bag, so that the operating force of the master bag is reduced, and the overall operating structure is simple to reduce the manufacturing cost. .
