Abstract

차량용 제동장치에 있어서, 브레이크 조작기구를 단순화시켜 작은 조작력으로도 주차 브레이크를 작동시킬 수 있고, 잔후륜을 동시에 제동시켜 큰 제동력을 발생시켜 안전한 주차를 가능케 하기 위하여, 브레이크 페달의 작동으로 유압을 발생시키는 마스터 실린더와; 상기 마스터 실린더와 유입라인으로 연결되어 마스터 실린더에서 발생된 유압을 유입하고, 전후륜에 각각 장착된 프론트 브레이크와 리얼 브레이크에 각각 공급라인으로 연결되어 공급라인으로 공급되는 유압을 조정하는 프로포셔닝 밸브와; 상기 프로포셔닝 밸브와 마스터 실린더를 연결하는 유입라인에 장착되어 주차 브레이크레버의 조작력에 의하여 온/오프되어 프론트 브레이크와 리어 브레이크로 공급된 유압의 귀환을 제한하여 브레이크 페달을 작동시키지 않아도 프론트 브레이크와 리어 브레이크르이 제동상태를 유지시키는 주차수단을 포함하는 차량용 제동장치.In a braking system for a vehicle, a brake operation mechanism is simplified to operate a parking brake even with a small operation force. In order to generate a large braking force by simultaneously braking the remaining rear wheels to enable safe parking, hydraulic pressure is generated by operation of a brake pedal A master cylinder; And a pressure control valve which is connected to the master cylinder and the inflow line to introduce the hydraulic pressure generated in the master cylinder and is connected to the front brake and the real brake respectively mounted on the front and rear wheels, Wow; And a brake pedal which is mounted on an inflow line connecting the proportioning valve and the master cylinder and is turned on and off by the operation force of the parking brake lever to restrict the return of the hydraulic pressure supplied to the front brake and the rear brake, And a parking means for maintaining the braking state of the rear brake.
