It is done to get the desired result.

이와 같은 조작력 배가장치중 유압을 이용하는 브레이크나 클러치장치는 도 1에 도시된 바와 같이, 운전자가 조작하는 페달(10)과, 이 페달(10)의 조작에 따라 작동되는 부스터에 의해 유압을 발생하는 마스터실린더(20) 및 이 실린더(20)에 의해 발생된 유압을 매개로 조작되어 원하는 결과를 얻는 어셈블리(클러치장치인 경우 클러치어셈블리(30)또는 브레이크장치인 경우 브레이크어셈블리(40))로 구성되어진다.As shown in FIG. 1, a brake or clutch device using hydraulic pressure among the operation force doubling devices generates hydraulic pressure by a pedal 10 operated by a driver and a booster operated according to the operation of the pedal 10. It is composed of an assembly (clutch assembly 30 in the case of a clutch device or a brake assembly 40 in the case of a brake device) which obtains a desired result by operating the master cylinder 20 and the hydraulic pressure generated by the cylinder 20. Lose.

여기서, 운전자의 초기 조작력을 유압을 매개로 배가시켜주는 조작장치인 마스터실린더(20)는 도 2에 도시된 바와 같이, 밀폐된 공간인 실린더(21)와, 이 실린더(21)의 상부에 구비되어 오일을 공급하는 리저버(25)로 이루어지되, 상기 실린더(21)는 일단이 부스터로드(B)에 의해 이동되는 제1피스톤(22)과 스프링(S)을 매개로 함께 이동되는 제2피스톤(23)이 내장됨과 더불어 상기 제1·2피스톤(22,23)사이와 상기 부스터로드(B)의 반대부위에 각각 형성된 제1·2포트(21a,21b)가 구비되어 진다.Here, the master cylinder 20, which is an operation device that doubles the driver's initial operating force by the hydraulic pressure, is provided with a cylinder 21, which is a closed space, and an upper portion of the cylinder 21, as shown in FIG. And a reservoir 25 for supplying oil, wherein the cylinder 21 has a first piston 22 having one end moved by a booster rod B and a second piston moved together through a spring S.

이하 본 발명의 작용을 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail.

운전자가 브레이크나 클러치장치의 페달(10)을 조작하면, 이 페달(10)의 조작에 따라 클러치스위치(10a)나 브레이크스위치(10b)중 1개의 스위치로부터 전기신호가 발생되어 콘트롤러(50)에 입력되어진다.When the driver operates the pedal 10 of the brake or clutch device, an electric signal is generated from one of the clutch switch 10a or the brake switch 10b according to the operation of the pedal 10, and the controller 50 is supplied to the controller 50. It is input.

이어, 상기 콘트롤러(50)의 내장된 프로그램에 따라 마스터실린더(20)의 제1·2·3포트(21a,21b,21c)에 각각 구비된 솔레노이드 밸브(21a',21b',21c')를 선택적으로 열어 상기 페달(10)의 조작에 따라 마스터실린더(20)에서 발생된 유압을 클러치어셈블리(30)나 브레이크어셈블리(40)중 1곳으로 전송하여 작동시켜주게 된다.Subsequently, the solenoid valves 21a ', 21b', and 21c 'provided in the first, second and third ports 21a, 21b, and 21c of the master cylinder 20 are installed according to the built-in program of the controller 50. By selectively opening the hydraulic pressure generated in the master cylinder 20 in accordance with the operation of the pedal 10 is transmitted to one of the clutch assembly 30 or the brake assembly 40 to operate.

즉, 이와 같은 작용을 브레이크 페달(10)의 조작에 따라 설명하면, 브레이크스위치(10b)의 전기적 신호에 따라 콘트롤러(50)에 의해 브레이크 어셈블리(40)쪽으로 연결된 제1·2포트(21a,21b)의 솔레노이드밸브(21a',21b')가 열리게 되고, 이와 동시에 페달(10)과 함께 조작되는 부tm터의 로드(B)에 의해 브레이크가압력(F')이 마스터실린더(20)의 실린더(21)에 내장된 제1피스톤(22)이 이동되어진다.That is, when such an operation is described according to the operation of the brake pedal 10, the first and second ports 21a and 21b connected to the brake assembly 40 by the controller 50 according to the electrical signal of the brake switch 10b. The solenoid valves 21a 'and 21b' are opened, and at the same time, the brake pressing force F 'is applied to the cylinder of the master cylinder 20 by the rod B of the booster which is operated together with the pedal 10. The first piston 22 embedded in 21 is moved.

이어, 상기 제1피스톤(22)의 이동에 따라 스프링(S)을 매개로 제2피스톤(23)이 이동되면서, 이 제1·2피스톤(22,23)사이에 형성된 제1포트(21a)를 통해 가압된 오일이 유출되어진다.Subsequently, as the second piston 23 moves through the spring S as the first piston 22 moves, the first port 21a formed between the first and second pistons 22 and 23. Pressurized oil is flowed out through.

또한, 상기 제2피스톤(23)의 이동에 따라 스프링(S)을 매개로 제3피스톤(24)이 이동되면서, 이 제2·3피스톤(23,24)사이에 형성된 제2포트(21b)를 통해 가압된오일이 유출되는데 이때, 상기 실린더(21)의 일측에 형성되어 이동되는 제3피스톤(24)에 의해 가압되는 오일은 제3포트(21c)의 유로를 막도록 콘트롤러(50)에 의해 닫힌 솔레노이드밸브(21c')에 의해 클러치어셈블리(30)쪽으로 유입되지 못하게 됨은 물론이다.In addition, as the third piston 24 is moved through the spring S as the second piston 23 moves, the second port 21b formed between the second and third pistons 23 and 24. Oil is pressurized through the outflow, at this time, the oil pressurized by the third piston 24 is formed on one side of the cylinder 21 is moved to the controller 50 to block the flow path of the third port (21c) The solenoid valve 21c ′ closed by the solenoid valve 21c ′ prevents the inflow into the clutch assembly 30.

이어, 브레이크페달(10)의 조작을 중지하면 브레이크스위치(10b)의 전기적신호를 받지 못한 콘트롤러(50)가 제1·2포트(21a,21b)의 솔레노이드밸브(21a',21b')를 닫게되고, 상기 마스터실린더(20)는 압축되었던 스프링(S)의 복원력에 의해 초기 상태로 복원되어진다.Then, when the operation of the brake pedal 10 is stopped, the controller 50 which has not received the electrical signal of the brake switch 10b causes the solenoid valves 21a 'and 21b' of the first and second ports 21a and 21b to be closed. The master cylinder 20 is restored to an initial state by the restoring force of the spring S that has been compressed.

한편, 운전자가 클러치장치를 조작하기 위해 클러치페달(10)을 조작하게 되면, 이 클러치페달(10)에 의해 클러치스위치(10a)의 전기적 신호가 콘트롤러(50)에 유입되고 이에 따라, 클러치어셈블리(30)로 연결된 제3포트(21c)의 솔레노이드밸브(21c')를 열어 유압회로를 형성시켜 전술한 브레이크장치의 조작시와 같이 마스터실린더(20)에서 가압된 유압을 전송하는 동일한 작용을 하므로 이에 대한 상세한 설명을 생략한다.On the other hand, when the driver operates the clutch pedal 10 to operate the clutch device, the electric signal of the clutch switch 10a flows into the controller 50 by the clutch pedal 10, and accordingly, the clutch assembly ( Since the solenoid valve 21c 'of the third port 21c connected to 30 is opened to form a hydraulic circuit, the same function of transmitting the pressurized hydraulic pressure in the master cylinder 20 as in the operation of the brake device is performed. Detailed description thereof will be omitted.

이상 설명한 바와 같이 본 발명에 의하면, 브레이크장치나 클러치장치가 하나의 마스터실린더를 공유하여 조작되는 장치에 따라 유압을 선택적으로 작용시켜 단가와 조립공정을 줄이면서도 효율성을 높일 수 있는 효과가 있게 된다.As described above, according to the present invention, the brake device or the clutch device can selectively operate hydraulic pressure according to a device operated by sharing one master cylinder, thereby increasing the efficiency while reducing the unit cost and the assembly process.
