본 발명은 바퀴의 허브나 드럼을 분해하지 않고서도 자동차의 브레이크 라이닝의 마모량을 확인할 수 있도록 하는 자동차의 브레이크 라이닝 마모량 감지장치에 관한 것으로, 더 자세하게는 운전석의 계기판넬에 설치된 경고등을 통해 브레이크 라이닝의 교환시기나 정비시기를 간편하게 알 수 있도록 개선한 것에 관한 것이다.The present invention relates to a brake lining wear detection device of a vehicle that enables to check the wear amount of the brake lining of the vehicle without disassembling the hub or drum of the wheel, and more specifically, through the warning lights installed on the instrument panel of the driver's seat It is about improving so that it is easy to know replacement time and maintenance time.

일반적으로 자동차를 운행함에 있어서는 위험상황에서 차량을 신속하게 정지시킬 수 있도록 하는 제동장치를 최적의 상태로 확보하는 것이 무엇보다도 중요하게 되며, 특히 화물을 적재하거나 탑승인원이 많은 중, 대형차량에 있어서는 항상 브레이크상태를 점검하는 것이 바람직하다.In general, when driving a vehicle, it is most important to have an optimum braking system that can stop the vehicle quickly in a dangerous situation. Especially, in a medium- and large-sized vehicle that loads cargo or has a large number of passengers. It is always advisable to check the brake condition.

본 발명은 특히 브레이크슈에 부착된 라이닝과 바퀴와 함께 회전하는 브레이크드럼의 마찰력을 이용하여 차량을 정지시키는 브레이크가 장착된 자동차에 관계하는 것으로, 이러한 형태의 브레이크를 장착한 자동차에 있어서는 브레이크의 반복사용에 의해 라이닝이 마모되면 브레이크페달의 유격은 커지게 되고 제동력은 저하되기 마련이다.The present invention relates in particular to a vehicle equipped with a brake which stops the vehicle by using the friction force of the brake drum rotating together with the wheels and the lining attached to the brake shoe. In the vehicle equipped with this type of brake, the brake is repeated. If the lining is worn by use, the play of the brake pedal will increase and the braking force will decrease.

따라서 상기 제동장치에 있어서는 안정된 제동력을 확보하기 위하여 적절한 시기에 마모된 라이닝을 교환해주는 것이 극히 바람직하다.Therefore, in the braking device, it is extremely desirable to replace the worn lining at an appropriate time in order to secure a stable braking force.

그러나 종래에 있어서는 제동장치의 라이닝의 마모상태를 확인하기 위해서는 바퀴를 분해하여야 했으므로 운전자가 브레이크페달로 전해지는 막연한 제동 감각만으로 라이닝의 마모상태를 추측해야 했고, 이와같이 감각적으로 제동력의 약화를 느낀 운전자의 요구나 정비사의 육안확인으로 라이닝을 교환해야 했기 때문에 작업시간이 과다하게 소요됨은 물론 부품 비용이 과다하게 지출되는 문제가 있었고, 자칫 라이닝의 교환시기를 놓치는 경우에는 브레이크슈나 드럼등의 파손은 물론 각종 안전사고가 유발되는 문제가 있었다.However, in the related art, the wheel had to be disassembled in order to check the wear state of the lining of the brake system. Therefore, the driver had to guess the wear state of the lining only by the vague sense of braking transmitted to the brake pedal. Since the lining had to be replaced due to the demand or the visual inspection of the mechanic, there was a problem of excessive work time and excessive parts cost.In case of missing the replacement time of the lining, damage of brake shoes or drums, as well as various There was a problem that caused a safety accident.

본 발명은 상기 종래의 실정을 감안하여 안출한 것이며, 그 목적은 브레이크 라이님의 마모상태와 교환시기를 손쉽게 확인할 수 있도록 함으로써 작업시간의 단축 및 부품비용의 절감을 도모할 수 있도록 하고, 드럼등의 제동장치의 다른 부품의 손상과 그로 인한 각종 안전사고를 예방할 수 있도록 하는 자동차의 브레이크 라이닝 마모량 감지장치를 제공하는 데에 있는 것이다.The present invention has been made in view of the above-mentioned conventional situation, and its object is to make it easy to check the wear state and the replacement time of the brake lining, so that it is possible to shorten the working time and reduce the parts cost, drums, etc. It is to provide a brake lining wear detection device of a vehicle which can prevent the damage of other parts of the brake system and the resulting safety accidents.

본 발명은 상기의 목적을 달성하기 위하여 브레이크 라이닝의 내부에 감지센서를 설치하고, 이 감지센서를 릴레이를 통해 운전석의 경보등에 연결하는 것을 특징으로 하며, 이하 그 구체적인 내용을 첨부도면을 통해 더욱 자세히 설명하면 다음과 같다.The present invention is characterized in that the sensor is installed in the interior of the brake lining to achieve the above object, the sensor is connected to the alarm of the driver's seat through a relay, the following detailed content through the accompanying drawings The explanation is as follows.

즉, 본 발명은 제1도와 같이 브레이크슈(10)의 상단에 부착된 라이닝(20)과 드럼(30)과의 마찰력을 이용하는 브레이크가 장착된 자동차에 있어서, 브레이크슈(10)와 라이닝(20)에 관통공(11)(12)을 형성하고, 이중홀더(41) 및 스프링(42)으로 지지되는 감지센서(40)의 선단부를 상기 관퉁공(11)(21)을 통해 라이닝(20)의 내부 중앙에 위치시켜서 되는 것이며, 아울러 제2도와 같이 상기 감지센서(40)를 한 쌍의 스위치접점(51)(52)을 갖는 릴레이(50)를 통해 운전석의 경보등(60)과 접속하여서 되는 것이다.That is, the present invention is a brake shoe 10 and the lining 20 in a vehicle equipped with a brake using a friction force between the lining 20 and the drum 30 attached to the upper end of the brake shoe 10 as shown in FIG. The through-holes 11 and 12 are formed in the through hole, and the front end portion of the sensing sensor 40 supported by the double holder 41 and the spring 42 is lined 20 through the holes 11 and 21. It is to be located in the center of the interior, and also connected to the alarm lamp 60 of the driver's seat through the relay 50 having a pair of switch contacts (51, 52) as shown in FIG. will be.

도시된 실시예에 있어서 감지센서(40)의 하단에 설치되는 터미날(43)은 더스트커버(70)에 고정되며, 도면 부호중 미 설명부호 44는 리드선, 80은 역 전류방지 다이오드이다.In the illustrated embodiment, the terminal 43 installed at the lower end of the sensor 40 is fixed to the dust cover 70, and reference numeral 44 in the reference numerals is a lead wire, and 80 is a reverse current prevention diode.

상기와 같이 구성된 본 발명에 있어서는 라이닝(20)의 상태가 양호할 때는 릴레이(50)가 오프접점(51)에 접속되어 경보등(60)이 소등된 상태로 있게 되고, 라이닝(20)이 점차 마모되어 감지센서(40)의 선단이 브레이크드럼(30)에 닿게 되면 릴fp이(50)가 온접점(52)에 접속되어 경보등(60)이 점등되어 곧바로 라이닝(20)의 마모상태를 알 수 있게 된다.In the present invention configured as described above, when the state of the lining 20 is good, the relay 50 is connected to the off contact 51 so that the alarm lamp 60 is turned off, and the lining 20 gradually wears out. When the tip of the detection sensor 40 touches the brake drum 30, the reel fp 50 is connected to the on-contact point 52, and the alarm lamp 60 is turned on, so that the wear state of the lining 20 can be immediately known. Will be.

상기에서 감지센서(40)를 통해 켜진 경보등(60)은 운전자가 브레이크페달에서 발을 떼어도 계속해서 점등된 상태를 유지하게 됨은 물론이다.The alarm lamp 60 turned on through the sensor 40 is maintained as long as the driver keeps on the light even when the driver takes his foot off the brake pedal.

이상에서와 같이 본 발명은 라이닝(20)의 마모상태를 운전석에서 손쉽게 확인할 수 있게 되는 것으로, 본 고안에 의하면 종래와 같이 불필요하게 라이닝(20)을 점검하지 않아도 되고, 사용가능한 라이닝(20)을 폐기하지 않아도 되므로 번거로운 정비에 따른 정비인력과 부품비용을 크게 절감할 수 있게 됨은 물론 브레이크드럼(30)의 파손에 따른 안전사고를 사전에 방지할 수 있게 되어 부품의 수명연장과 자동차의 안전운행에도 크게 기여할 수 있게 되는 등의 효과를 얻을 수 있게 된다.As described above, the present invention is to be able to easily check the wear state of the lining 20 in the driver's seat, according to the present invention do not need to check the lining 20 unnecessarily as in the prior art, the lining 20 that can be used Since it does not have to be disposed of, it is possible to greatly reduce maintenance manpower and parts costs due to cumbersome maintenance, and it is possible to prevent safety accidents due to breakage of the brake drum 30 in advance, thereby prolonging the life of the parts and driving the car safely. It is possible to obtain such effects as being able to contribute greatly.
