Abstract

본 발명은 유압을 이용하여 클러치를 조작(동력 차단)하는 유압식 클러치 조작장치에 관한 것으로, 클러치 페달과 연결되어 유압을 발생하는 클러치 마스터 실린더와, 상기 클러치 마스터 실린더와 유압 파이프로 연결되는 것으로써 클러치 마스터 실린더로부터 유압을 전달 받아 릴리스 포크를 구동시키는 클러치 슬레이브 실린더를 구비한 유압식 클러치 조작장치에 있어서, 상기 유압 파이프의 중간부에 클러치 조작후 리턴되는 유압의 속도를 자연시키는 유압흐름조절수단을 설치하여 클러치 조작후 자동으로 반클러치 상태를 유지하도록 구성한 것이다. 이와 같은 본 발명의 유압식 클러치 조작장치에 의하면, 클러치를 조작하여 변속한 후 출발함에 있어서 운전자의 후속 동작 없이도 반클러치 상태가 유지되므로 클러치 페달로부터 발을 떼고 액설레이트를 전개하면서 출발할 수 있으므로 종래와 같이 인위적으로 반클러치 상태를 유지하여야 함에 따른 운전자의 피로감을 덜어 줄 수 있다. 또한 신호 대기중의 클러치 페달 조작 미스에 의한 앞차와의 접촉 사고도 클러치 미트 타임을 길게 가질 수 있으므로 브레이크를 밟을 수 있는 충분한 시간을 확보할 수 있어 안전 사고의 위험을 방지할 수 있다. 또한 클러치 파이프 내경의 체적비에 의한 유압 진동 감쇄 효과로 구동계 폭팔 진동에 따른 클러치 페달의 진동을 보다 효과적으로 방지할 수 있어 승차감을 향상시킬 수 있다.The present invention relates to a hydraulic clutch operating device for operating a clutch using a hydraulic pressure (power cut off), wherein a clutch master cylinder is connected to a clutch pedal to generate hydraulic pressure, and is connected to the clutch master cylinder and a hydraulic pipe. In the hydraulic clutch operating device having a clutch slave cylinder for driving the release fork by receiving the hydraulic pressure from the master cylinder, the hydraulic flow control means for naturalizing the speed of the hydraulic pressure returned after the clutch operation in the middle of the hydraulic pipe It is configured to automatically maintain the half clutch state after clutch operation. According to the hydraulic clutch operation apparatus of the present invention, the semi-clutch state is maintained even after starting the shift after operating the clutch, so that the vehicle can start while releasing the foot from the clutch pedal and deploying the sulphate. Likewise, it is possible to reduce the fatigue of the driver by artificially maintaining the anti-clutch state. In addition, the accident of contact with the vehicle in front of the clutch pedal operation miss while waiting for the signal can have a long clutch mit time, so that sufficient time for the brake can be secured, thereby preventing the risk of a safety accident. In addition, the hydraulic vibration attenuation effect due to the volume ratio of the inner diameter of the clutch pipe can effectively prevent the vibration of the clutch pedal due to the vibration of the drive system arm, thereby improving the riding comfort.
