Abstract

본 발명은 브레이크 마찰재의 마찰계수 측정장치에 관한 것으로, 보다 상세하게는 마이크로 컴퓨터와 솔레노이드를 이용하여 마찰계수의 실차측정시험을 보다 용이하게 하는 마찰계수 측정장치에 관한 것이다.The present invention relates to a friction coefficient measuring device of the brake friction material, and more particularly, to a friction coefficient measuring device that facilitates the actual vehicle measurement test of the friction coefficient using a microcomputer and a solenoid.

이러한 본 발명은 마스터 실린더의 유압관에 솔레노이드와 유압 센서를 설치하고 차량에는 스피도미터와 감속도계를 설치하되, 상기 유압 센서, 스피도미터, 감속도계의 시그널 선을 마이크로 컴퓨터에 연결하고, 솔레노이드의 작동을 위한 시그널 선도 마이크로 컴퓨터에 연결하며, 차량무게, 타이어반경, 실린더면적, 브레이크 유효반경 등의 설정값을 입력과 함께 측정하고자하는 유압을 마이크로 컴퓨터에 입력하여서 차량의 주행중에 운전자가 브레이크 페달을 밟아 제동을 시키면 유압관의 압력이 유압 센서에 의해 측정되고 이 시그널이 마이크로 컴퓨터에 전달되어 처리되면서 유압관의 압력이 설정치에 도달하면 솔레노이드에 전원을 인가시켜 유압관의 압력을 차단하고 정지할때까지 이를 유지시키게 하여 제동중에 발생된 감속도와 유압 데이터를 마이크로 컴퓨터가 입력된 산출식에 의해 연산하여 모니터를 통해 출력되게 한 것이다.The present invention is to install a solenoid and a hydraulic sensor in the hydraulic tube of the master cylinder, and to install a speedometer and a decelerometer in the vehicle, connecting the signal line of the hydraulic sensor, speedometer, decelerometer to the microcomputer, for the operation of the solenoid It is connected to the signal leading microcomputer and inputs the setting values such as the vehicle weight, tire radius, cylinder area and brake effective radius together with the hydraulic pressure to be measured to the microcomputer so that the driver presses the brake pedal while driving the vehicle. When the pressure of the hydraulic pipe is measured by the hydraulic sensor and this signal is transmitted to the microcomputer and processed, when the pressure of the hydraulic pipe reaches the set value, the solenoid is energized to cut off the pressure of the hydraulic pipe and hold it until it stops. Deceleration and hydraulic pressure generated during braking It is a to the data calculated by the calculation formula of the micro computer is input to be output on the monitor.
