본 발명은 차량용 클러치 페달 답력저감장치에 관한 것으로서, 더욱 상세하게는 클러치를 조작할 때 가압되어 이동하는 유압유의 이동 경로의 단면적이 가변될 수 있도록 실린더 내부에 축관부를 형성하여 운전자에게 전달되는 답력을 최소 화 할 수 있는 차량용 클러치 페달 답력저감장치에 관한 것이다.The present invention relates to a clutch pedal effort reduction device for a vehicle, and more particularly, to form a shaft tube in a cylinder so that the cross-sectional area of a moving path of hydraulic oil that is pressurized and moved when the clutch is operated can be used to provide a response force transmitted to a driver. The present invention relates to a clutch pedal effort reduction device for a vehicle that can be minimized.

일반적으로 수동변속기가 장착된 차량에는 엔진에서 발생된 동력을 선택적으로 공급 및 차단할 수 있는 클러치가 설치되어 있는바, 이러한 클러치를 운전자가 조작할 때 운전자에게 전달되는 진동을 최소화 할 수 있는 장치가 절실히 요구되고 있는 실정이다.In general, a vehicle equipped with a manual transmission is provided with a clutch for selectively supplying and cutting off power generated by an engine, and a device capable of minimizing vibration transmitted to the driver when the clutch is operated by the driver is urgently needed. It is a required situation.

종래의 클러치 시스템은 도1에 나타낸 바와 같이 클러치페달(10)과, 이 클러치페달(10)에 연결된 마스터 실린더 조립체(20)와, 이 마스터 실린더 조립체(20)에 연결된 릴리스 실린더 조립체(30)와, 상기 마스터 실린더 조립체(20)와 릴리스 실린더 조립체(30)를 연결하는 클러치파이프(41) 사이에 연결되어 진동을 흡수하는 메탈 댐퍼(50) 및 코일부(60)로 구성된다.The conventional clutch system includes a clutch pedal 10, a master cylinder assembly 20 connected to the clutch pedal 10, a release cylinder assembly 30 connected to the master cylinder assembly 20, as shown in FIG. A metal damper 50 and a coil unit 60 connected between the master cylinder assembly 20 and the clutch pipe 41 connecting the release cylinder assembly 30 to absorb vibrations.

이러한 클러치 시스템은 운전자가 클러치페달(10)을 조작하게 되면, 마스터 실린더 조립체(20) 내에 유압이 발생하게 되며, 이 유압은 릴리스 실린더 조립체(30)의 푸시 로드(31)를 조작하여 트랜스미션 측의 클러치 레버(도면 미도시)를 밀어 동력을 차단하게 된다.In this clutch system, when the driver operates the clutch pedal 10, hydraulic pressure is generated in the master cylinder assembly 20, and the hydraulic pressure is operated by operating the push rod 31 of the release cylinder assembly 30. Push the clutch lever (not shown) to shut off power.

반대로 클러치 페달(10)의 답력을 해제하게 되면, 릴리스 실린더 조립체(30)에 작용하던 유압이 리턴되며, 푸시로드(31)가 원위치로 복귀되며 엔진의 동력이 트랜스미션으로 전달된다.On the contrary, when releasing the pedal force of the clutch pedal 10, the hydraulic pressure acting on the release cylinder assembly 30 is returned, the push rod 31 is returned to its original position, and the engine power is transmitted to the transmission.

이때, 엔진에서 발생하는 진동이 유압에 작용하면서 맥동진동을 발생시키게 되며, 이러한 진동이 클러치 파이프(41)를 통해 클러치페달(10)에 그대로 전달되어 불편함을 초래하게 된다.At this time, the vibration generated in the engine acts on the hydraulic pressure to generate a pulsating vibration, which is transmitted to the clutch pedal 10 through the clutch pipe 41 as it is, causing inconvenience.

한편, 종래의 마스터 실린더 조립체(20)는 도2에 나타낸 바와 같이 실린더(22)의 내부에 유압피스톤(21)이 이동 가능하게 설치되어 있고, 그 유압피스톤(21)의 외측 둘레면에는 기밀을 유지하기 위한 실링부재(23)가 설치되어 있다.On the other hand, the conventional master cylinder assembly 20, as shown in Figure 2, the hydraulic piston 21 is provided to be movable inside the cylinder 22, the outer peripheral surface of the hydraulic piston 21 is airtight The sealing member 23 for holding is provided.

그리고, 상기 실린더(22)의 내부에는 유압피스톤(21)을 탄력 지지하기 위한 스프링(24)이 내장되어 있고, 상기 실린더(22)의 단부에는 유압유가 이동되는 클러치 파이프(41)가 연결되어 있다.In addition, a spring 24 for elastically supporting the hydraulic piston 21 is built in the cylinder 22, and a clutch pipe 41 through which hydraulic oil is moved is connected to an end of the cylinder 22. .

따라서, 운전자가 클러치 폐달을 밟으면, 유압피스톤(21)이 실린더(22)의 내부에서 이동하게 되고, 상기 유압피스톤(21)이 이동되면, 실린더(22)의 내부에 충입된 유압유는 클러치 파이프(41)를 통하여 배출되는 것이다.Therefore, when the driver steps on the clutch closing, the hydraulic piston 21 moves inside the cylinder 22, and when the hydraulic piston 21 moves, the hydraulic oil filled in the cylinder 22 passes through the clutch pipe ( It is discharged through 41).

한편, 상기 유압피스톤(21)이 이동될 때 실린더(22)에 내장된 스프링(24)은 압축되는 것이고, 운전자가 클러치 폐달을 놓으면 상기 스프링(24)의 복원력에 의해서 유압피스톤(21)은 초기상태로 이동하는 것이다.Meanwhile, when the hydraulic piston 21 is moved, the spring 24 embedded in the cylinder 22 is compressed, and when the driver releases the clutch closing, the hydraulic piston 21 is initialized by the restoring force of the spring 24. Is to move to a state.

그러나 이러한 종래의 장치는 실린더(22) 내부의 직경이 동일하게 이루어져 있으므로 클러치 폐달을 밟을 때 실린더(22) 내부에 충입된 유압유에는 유압피스톤(21)이 설치된 방향 및 스프링(24)이 설치된 방향 즉, 내부 전체의 압력이 균일하게 작용하게 되어 상기 클러치 폐달을 밟는 운전자에게 전달되는 답력이 증가하는 문제점이 있었다. However, since the conventional apparatus has the same diameter in the cylinder 22, the hydraulic oil filled in the cylinder 22 when the clutch is closed, the direction in which the hydraulic piston 21 is installed and the direction in which the spring 24 is installed, There is a problem in that the pressure of the entire interior is uniformly acted on, thereby increasing the responsiveness delivered to the driver who steps on the clutch pedal.

본 발명은 상기한 문제점을 해결하기 위하여 발명한 것으로서, 그 목적은 실린더의 내부에 축관부를 형성하여 클러치를 조작할 때 가압되어 이동하는 유압유의 이동 경로의 단면적이 가변시켜 운전자에게 전달되는 답력을 최소화 할 수 있는 차량용 클러치 페달 답력저감장치를 제공함에 있다.The present invention has been invented to solve the above problems, the object of which is to form a shaft tube in the interior of the cylinder to change the cross-sectional area of the moving path of the hydraulic oil pressurized when operating the clutch to minimize the effort delivered to the driver The present invention provides a vehicle clutch pedal effort reduction device.

And a sealing member provided on an outer circumferential surface of the hydraulic piston, and a spring provided inside the cylinder to elastically support the hydraulic piston.

이와 같은 특징을 갖는 본 발명을 상세하게 설명하면 다음과 같다.Referring to the present invention having such characteristics in detail as follows.

도3은 본 발명에 따른 마스터 실린더 조립체를 나타낸 단면도이고, 도4는 본 발명에 따른 마스터 실린더 조립체에 작용하는 답력을 나타낸 그래프이다.3 is a cross-sectional view showing a master cylinder assembly according to the present invention, Figure 4 is a graph showing the acting force acting on the master cylinder assembly according to the present invention.

여기에서 참조되는 바와 같이 본 발명은 운전자에 의해서 조작되는 클러치 폐달에 연결되는 유압피스톤(21)이 마련되어 있고, 상기 유압피스톤(21)은 실린더(22)의 내부에 이동 가능하게 끼워져 있다.As referred to herein, the present invention is provided with a hydraulic piston 21 that is connected to the clutch closing moon operated by the driver, the hydraulic piston 21 is fitted into the cylinder 22 so as to be movable.

한편, 상기 실린더(22)의 내측 둘레면에는 그 실린더(22)의 내부 면적이 가변되도록 축관부(25)가 형성되어 있되, 그 축관부(25)는 중앙의 직경(d)은 작고 양측의 직경(D)은 크게 형성하는 것이 바람직하다.On the other hand, the inner circumferential surface of the cylinder 22 is formed with a shaft tube portion 25 so that the inner area of the cylinder 22 is variable, the shaft tube portion 25 of the center diameter (d) is small and both sides It is preferable to form the diameter D large.

그리고, 상기 유압피스톤(21)의 외측 둘레면에는 실링부재(23)가 설치되어 있다.A sealing member 23 is provided on the outer circumferential surface of the hydraulic piston 21.

또한, 상기 실린더(22)의 내부에는 상기 유압피스톤(21)을 탄력 지지하는 스프링(24)이 내장되어 있다.In addition, a spring 24 for elastically supporting the hydraulic piston 21 is built in the cylinder 22.

이와 같이 구성된 본 발명을 상세히 설명하면 다음과 같다.Referring to the present invention configured as described in detail as follows.

따라서, 운전자가 클러치 폐달을 밟으면, 유압피스톤(21)이 실린더(22)의 내부에서 이동하게 되고, 상기 유압피스톤(21)이 이동되면, 실린더(22)의 내부에 충입된 유압유는 클러치 파이프(41)를 통하여 배출되는 것이다.Therefore, when the driver steps on the clutch closing, the hydraulic piston 21 moves inside the cylinder 22, and when the hydraulic piston 21 moves, the hydraulic oil filled in the cylinder 22 passes through the clutch pipe ( It is discharged through 41).

상기와 같이 실린더(22) 내부에서 이동하는 유압유는 그 실린더(22) 내부에 형성된 축관부(25)를 통과하면서 압력이 변경되는 것이다.As described above, the hydraulic oil moving inside the cylinder 22 is changed in pressure while passing through the shaft pipe portion 25 formed inside the cylinder 22.

즉, 유압피스톤(21)이 설치된 방향과 스프링(24)이 설치된 방향의 내부 압력이 서로 다르게 작용하게 되는 것이다.That is, the internal pressure in the direction in which the hydraulic piston 21 is installed and the direction in which the spring 24 is installed are different from each other.

한편, 상기 유압피스톤(21)이 이동될 때 실린더(22)에 내장된 스프링(24)은 압축되는 것이고, 운전자가 클러치 폐달을 놓으면 상기 스프링(24)의 복원력에 의해서 유압피스톤(21)은 초기상태로 이동하는 것이다.Meanwhile, when the hydraulic piston 21 is moved, the spring 24 embedded in the cylinder 22 is compressed, and when the driver releases the clutch closing, the hydraulic piston 21 is initialized by the restoring force of the spring 24. Is to move to a state.

이와 같이 본 발명에 의하면 실린더(22)의 내부에 마련된 축관부(25)에 의해서 상기 실린더(22)의 내부를 이동하는 유압유의 압력이 실린더(22) 양측에서 서로 다르게 작용하게 되므로 클러치 폐달을 밟을 때 운전자에게 전달되는 답력은 도4에 나타낸 바와 같이 감소되는 것이다.As described above, according to the present invention, the pressure of the hydraulic oil moving inside the cylinder 22 is acted differently on both sides of the cylinder 22 by the shaft pipe 25 provided in the cylinder 22, so that the clutch pedal is pressed down. When the power delivered to the driver is reduced as shown in FIG.

이와 같이 본 발명은 실린더 내부의 단면적이 가변되도록 하여 클러치 페달 을 밟을 때 운전자에게 전달되는 답력을 감소시켜 쾌적한 운전환경을 제공할 수 있는 특유의 효과가 있다.As described above, the present invention has a unique effect of providing a comfortable driving environment by reducing the power delivered to the driver when the clutch pedal is pressed by changing the cross-sectional area inside the cylinder.
