본 고안의 에어마스터 스트로크별 액압측정 시스템에 관한 것으로서, 특히 에어탱크와 브레이크페달을 연결하여 에어마스터로 공기를 공급하는 에어호스와, 스트로크 조절나사로 에어마스터의 스트로크를 자유롭게 조절 하도록 하는 슬리브실린더와, 슬리브실린더에 연결되어 에어마스터 출력액압의 변화를 측정하는 액압게이지와, 압력게이지에 연결되어 압력게이지의 측정값을 증폭하는 AMP증폭기와, 상기 AMP증폭기의 증폭된 값을 기록하는 라피고타기록기를 포함하는 브레이크페달 시스템을 이용하여 차량의 급제동이나 브레이크페달의 스트로크별로 액압 특성을 찾아서 액압변동 곡선을 분석하도록 하는 에어마스터 스트로크별 액압측정 시스템에 관한 것이다.The present invention relates to a hydraulic pressure measurement system for each stroke of the air master, and in particular, an air hose for supplying air to the air master by connecting the air tank and the brake pedal, a sleeve cylinder for freely adjusting the stroke of the air master with a stroke adjustment screw, A hydraulic gauge connected to the sleeve cylinder to measure a change in the air master output hydraulic pressure, an AMP amplifier connected to the pressure gauge to amplify the measured value of the pressure gauge, and a raffigot recorder to record the amplified value of the AMP amplifier. The present invention relates to a hydraulic pressure measurement system for each air master stroke, which analyzes a hydraulic pressure curve by finding hydraulic characteristics for each brake or stroke of a vehicle using a brake pedal system.
일반적으로 종래의 에어마스터 스트로크별 액압측정 시스템에서 에어마스터는 압축된 공기의 유입으로서 배력이 발생되고 그 힘으로 대형차들의 브레이크가 작동되어지는 것으로서 최근 승용차들은 ABS나 그밖의 구성으로 제동력을 향상시키는데 많은 노력이 이루어지고 있다.In general, in the conventional air master stroke-by-stroke hydraulic pressure measurement system, the air master generates power by the inflow of compressed air, and the brakes of the large cars are actuated by the force. In recent years, the passenger cars have been used to improve the braking force with ABS or other components. Efforts are being made.
실제로 대형트럭이나 버스에서 이루어지는 제동력은 승용차처럼 안정적이지 못하고 변동의 우려가 많이 있는데 기존에 이용되어지는 에어마스터 시험기에서는 압력의 응답속도가 느려서 에어마스터의 단품 상태에서 나타나는 출력액압의 변동을 측정할 수 없었고 브레이크 해제시 되돌림 시간을 측정할 수 없는 문제점들이 있었다.Actually, the braking force in a large truck or bus is not as stable as a passenger car, and there is a lot of fluctuation. However, in the existing air master tester, the response speed of the pressure is slow, and thus the fluctuation of the output hydraulic pressure in the air master unit can be measured. There was a problem that the return time could not be measured when the brake was released.
본 고안은 이와 같은 문제점을 개선하기 위하여 안출한 것으로서, 본 고안의 목적은 에어탱크와 에어마스터 사이에 브레이크페달을 설치하여 상기 브레이크페달을 밟는 순간 고압이 직접 에어마스터로 공급되어 응답속도가 빠르게 나타나도록 함으로서, 급제동시의 응답특성을 파악하는 것이 용이하게 이루어지도록 하고, 슬리브실린더에 설치된 스트로크 조절나사에 의해 에어마스터의 스트로크가 자유롭게 조절되도록 함은 물론, 슬리브실린더에 연결되어 에어마스터 출력액압의 변화를 측정하는 액압게이지와, 압력게이지에 연결되어 압력게이지의 측정값을 증폭하는 AMP증폭기와, 상기 AMP증폭기의 증폭된 값을 기록하는 라피고타기록기를 포함하는 브레이크페달 시스템을 이용하여 차량의 급제동이나 브레이크페달의 스트로크별로 액압 특성을 찾아서 액압변동 곡선을 분석하도록 하는 에어마스터 스트로크별 액압측정 시스템을 제공하는데 있다.The present invention is devised to improve such a problem, the object of the present invention is to install a brake pedal between the air tank and the air master when pressing the brake pedal when the high pressure is directly supplied to the air master, the response speed appears quickly By making it easy to grasp the response characteristics during sudden braking, the stroke of the air master can be freely adjusted by the stroke adjusting screw installed in the sleeve cylinder, and connected to the sleeve cylinder to change the air master output hydraulic pressure. A brake pedal system including a hydraulic gauge for measuring the pressure, an AMP amplifier connected to the pressure gauge and amplifying the measured value of the pressure gauge, and a raffigot recorder for recording the amplified value of the AMP amplifier, Hydraulic characteristics for each stroke of brake pedal To provide a hydraulic pressure measurement system for each air master stroke to find and analyze the hydraulic pressure curve.
