Even in this situation, the driving time for using a car increases, thereby providing a comfortable and safe driving environment. When driving so many times, a braking device is used to decelerate or stop a driving car and maintain a parking state. This braking device increases the driver's operating force by using a link and hydraulic pressure. And a main body that generates braking force by receiving the force.

상기 제동장치에는 앞바퀴 및 뒤바퀴의 안쪽에 결합되어 있는 브레이크드럼 또는 브레이크디스크등에 마찰재인 브레이크라이닝이 패드 또는 디스크구조로 설치되어 마찰력을 이용하는 제동력을 발생시킴으로 주행중 운전자가 브레이크페달을 밟게 되면 앞뒷바퀴에 제동력이 발생하도록 되어있다.The braking device has a brake lining, which is a friction material, is installed on the brake drum or brake disk, which is coupled to the inside of the front wheel and the rear wheel, and is installed in a pad or disk structure to generate a braking force using frictional force. The braking force is to be generated.

그러나, 상기 브레이크라이닝의 마모상태를 감지하는 보조수단이 없어 주행중 운전자가 브레이크라이닝의 마모상태를 알지 못하기 때문에 라이닝의 교환시기에 대한 궁금한 점과 브레이크의 소음증가등을 유발하게 되었다.However, since there is no auxiliary means for detecting the wear state of the brake lining, the driver does not know the wear state of the brake lining while driving, causing questions about the replacement timing of the lining and an increase in noise of the brake.

이에 본 고안은 상기와 같은 사정을 감안하여 안출한 것으로, 앞바퀴 및 뒷바퀴에 설치되는 브레이크라이닝의 한위치에 검출부를 설치하고 이를 전선을 통해 운전석의 경보장치에 연결해 놓음으로 상기 브레이크라이닝의 패드나 디스크가 장시간 사용에 따른 마모상태를 상기 경보장치나 계기판을 통해 알려주어 운전석에서 쉽게 라이닝의 교환시기를 시청각으로 알 수 있어 쾌적한 운전환경을 조성해 주는 브레이크라이닝의 마모감지장치를 제공하고자 함에 그 목적이 있다.The present invention has been conceived in view of the above circumstances, by installing a detection unit at one position of the brake lining to be installed on the front wheel and the rear wheel and connecting it to the alarm device of the driver's seat through a wire to the pad or disc of the brake lining The purpose of the present invention is to provide a wear detection device of the brake lining that creates a pleasant driving environment by providing a visual and visual indication of the replacement time of the lining easily from the driver's seat by informing the wear state of the wear through the alarm device or the instrument panel. .
