Description
본 고안은 브레이크의 작동상태를 감지하여 그 고장 여부를 감지해낼 수 있도록 하여 사고를 방지할 수 있도록 한 브레이크 고장감지 장치에 관한 것이다.The present invention relates to a brake failure detection device that can detect the operating state of the brake to detect whether the failure is to prevent an accident.
대부분의 운전자들은 브레이크에 대하여 브레이크 오일, 라이닝정도만을 검사하여 현재의 브레이크의 작동상태가 어떠한 가를 인지하게 되며, 주행중 약간의 제동력 및 제동거리의 이상이 느껴지더라도 가볍게 넘기는 경우가 대부분이다.Most drivers only check the brake oil and lining degree of the brake to know how the current brake is operating. In most cases, even if a slight braking force and abnormal braking distance are felt during driving, the driver passes the brake lightly.
이와 같이, 파이프로부터 전달되는 유압의 세거나 회로의 고장으로 인하여 프론트 브레이크 또는 리어 브레이크가 고장이 난 경우 제동력이 감소되고, 제동거리가 걸어져 대형사고의 위험이 뒤따르게 된다.As such, when the front brake or the rear brake fails due to the hydraulic pressure or the circuit breakdown transmitted from the pipe, the braking force is reduced, and the braking distance is walked, thereby causing a risk of a large accident.
따라서, 본 고안에서는 상기에서와 같은 문제점을 해결하기 위하여 실린더의 양쪽출구에 압력센서를 구성하여 각각의 압력센서로부터 감지되는 압력을 비교하여 비교결과에 따라 브레이크의 이상유무를 판별하고, 판별된 결과로부터 일정전압과 비교하여 프론트 브레이크 및 리어 브레이크의 고장을 판별할 수 있도록 하여 운전자에게 알려사전에 대형사고의 위험으로부터 운전자를 보호할 수 있도록 한 것이다.Therefore, in the present invention, in order to solve the problems as described above, by configuring the pressure sensor at both exits of the cylinder to compare the pressure sensed from each pressure sensor to determine the abnormality of the brake according to the comparison result, the determined result It is possible to identify the failure of the front brake and the rear brake in comparison with the constant voltage from the driver so that the driver can be protected in advance from the risk of a major accident.

이하, 상기 목적을 달성하기 위한 본 고안의 일실시에를 첨부된 도면 제 1도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to Figure 1 of the accompanying drawings, an embodiment of the present invention for achieving the above object will be described in detail.
먼저, 본 고안의 구성은 템덤 마스크 실린더의 양측 출구(1,2)에 구성되어 오일공급탱크(5)로부터 공급되어 1차피스톤(3) 및 2차 피스톤(4)의 행정에 의하여 출력되는 유압을 감지하는 압력센서(6,7)와, 상기 압력센서(6,7)로 부터 감지된 각 1차출구(1) 및 2차 출구(2)의 압력을 비교하는 비교기(8)와, 비교기(8)의 비교결과에 따른 출력전압(VO)을 정류하는 정류기(9)와, 코일(L1)을 통해 정류된 전압을 입력받아 점등되어 운전자에게 브레이크의 고장여부를 알려주도록 하는 발광다이오드(LED1)로 구성된다.First, the construction of the present invention is configured at both outlets (1, 2) of the tandem mask cylinder is supplied from the oil supply tank (5) and output by the stroke of the primary piston (3) and the secondary piston (4) And a comparator 8 for comparing the pressures of the respective primary outlets 1 and the secondary outlets 2 detected by the pressure sensors 6 and 7, Rectifier 9 for rectifying the output voltage (V O ) according to the comparison result of (8) and the light-emitting diode which is lit by receiving the rectified voltage through the coil (L1) to inform the driver whether the brake is broken ( LED1).
상기와 같이 구성된 본 고안의 일실시예를 설명하면 다음과 같다.Referring to one embodiment of the present invention configured as described above are as follows.
본 고안에서는 템덤 마스크 실린더의 양측 출구(1,2)로 부터 그 압력변화를 비교하여 그 비교결과에 따라 브레이크의 고장여부를 판별하고, 비교결과에 따른 전압을 일정전압(OV)과 비교하여 프론트 브레이크가 고장인지, 리어 브레이크가 고장인지를 판정할 수 있도록 한 것으로, 먼저 양측 출구(1,2)에는 압력센서(6,7)가 각각 구성되어 있다.In the present invention, the pressure change is compared from both outlets (1, 2) of the tandem mask cylinder to determine whether the brake is broken according to the comparison result, and the voltage according to the comparison result is compared with the constant voltage (OV). It is possible to determine whether the brake is broken or the rear brake is broken. First, the pressure sensors 6 and 7 are formed at both outlets 1 and 2, respectively.
상기와 같이 구성되는 압력센서(6,7)에서는 각 1차출구(1) 및 2차 출구(2)의 압력을 감지하게 되고, 이를 비교기(8)로 전달하게 된다.In the pressure sensors 6 and 7 configured as described above, the pressures of the respective primary outlets 1 and the secondary outlets 2 are sensed and transmitted to the comparator 8.
비교기(8)에서는 이와 같은 압력변화에 따른 신호 전압(V1,V2)을 입력받아 이들을 비교하게 되고, 비교결과에 따른 신호전압(V0)을 출력하게 된다.The comparator 8 receives the signal voltages V 1 and V 2 according to the pressure change, compares them, and outputs the signal voltage V 0 according to the comparison result.
이때, 비교기(8)에서는 1차측 출구(10의 압력센서(6)에서 출력된 전압(V1)과 2차측 압력센서(7)의 출력전압(V2)이 다를 경우에 브레이크가 고장났다고 판단할 수 있는 것이다.In this case, the comparator 8 in the primary-side outlet (the brake failure natdago if the output voltage (V 2) of the voltage (V 1) and the outlet pressure sensor 7, output from the pressure sensor 6 of the 10 are different from the determination You can do it.
이후, 브레이크가 고장났을 경우에는 비교기(8)의 출력전압(V0)이 발생하게 되고, 이에 따라 정류기(9)에서 정류하여 발광다이오드(LED1)를 점등시켜 운전자에게 이를 알리게 된다.Subsequently, when the brake is broken, the output voltage V 0 of the comparator 8 is generated. As a result, the rectifier 9 is rectified to light up the light emitting diode LED1 to notify the driver.
여기서, 출력전압(V0)에 있어서 V00 즉, 1차측 압력센서(6)의 출력전압(V1)이 2차측 압력센서(7)의 출력전압(V2)보다 작을 경우에는 프론트 브레이크가 고장난 경우이며, V00 즉, 1차측 압력센서(6)의 출력전압(V1)이 2차측 압력센서(7)의 출력전압(V2)보다 클경우에는 리어 브레이크가 고장난 것이라고 판정할 수 있다.Here, when the output voltage V 0 is smaller than V 0 0, that is, the output voltage V 1 of the primary pressure sensor 6 is smaller than the output voltage V 2 of the secondary pressure sensor 7. that is, if failed, V 0 0 that is, when the output voltage (V 1) of the inlet pressure sensor 6 is greater than the output voltage (V 2) of the outlet pressure sensor 7 is provided to determine that failed the rear brake Can be.
이와 같은 결과에 따라서 발광다이오드(LED1)를 점등시켜 주므로서, 운전자로 하여금 브레이크의 고장여부를 인식할 수 있도록 하는 것이다.According to such a result, the light emitting diode LED1 is turned on so that the driver can recognize whether the brake is broken.
이상에서 설명한 바와 같이, 실린더의 양측 출구의 압력을 비교하여 브레이크의 고장여부를 판별하고, 1차측 출구와 2차측 출구의 센싱압력을 비교하여 프론트 브레이크 또는 리어 브레이크의 고장여부를 판정하여 이를 표시수단을 통하여 알려주도록 하므로서, 운전자로 하여금 이를 인식하도록 하여 사고를 사전에 방지할 수 있게 되는 효과가 있는 것이다.As described above, by comparing the pressures of the two outlets of the cylinder to determine whether the brake is broken, by comparing the sensing pressure of the primary outlet and the secondary outlet, it is determined whether the front brake or the rear brake is broken and displaying the result. By letting you know through, the driver is aware of this effect is to prevent accidents in advance.
