Description

타이밍 벨트의 교환시기를 알려주는 시스템System that informs timing belt replacement

본 발명은 차량용 타이밍 벨트의 교환시기를 알려주는 시스템에 관한 것으로, 특히 차량의 일정거리 주행후 타이밍 벨트의 상태를 점검하여 사용자에게 경고할 수 있도록 함으로써, 차량의 주행중에 타이밍 벨트의 절단으로 인한 차량 고장을 방지할 수 있도록 하여 사용자에게 편의를 제공할 수 있도록 한 타이밍 벨트의 교환 시기를 알려주는 시스템에 관한 것이다.The present invention relates to a system for notifying the timing of replacement of a vehicle timing belt, and in particular, by checking the state of the timing belt after driving a certain distance of the vehicle to warn the user, the vehicle caused by the cutting of the timing belt while driving the vehicle. The present invention relates to a system for notifying the timing of replacement of a timing belt that provides a user convenience by preventing a failure.

일반적으로 차량에는 구동력을 얻기위한 엔진을 설치하고, 상기 엔진에 설치된 각각의 밸브가 일체로 연결된 오버 헤드 캠 샤프트와 플라이 휠을 연결하는 타이밍 벨트를 설치하였는 바, 상기 타이밍 벨트는 상기 엔진으로 흡입되는 공기와 연료를 받아들이는 흡기행정과 상기 공기와 연료를 압축하는 압축행정과 상기 압축된 공기와 연료를 폭발시키는 폭발행정과 상기 폭발에 의해 연소되는 가스를 외부로 배출시키는 배기행정의 순서가 정확하게 작동될 수 있도록 조정을 하는 것이다.In general, a vehicle is provided with an engine for obtaining driving force, and a timing belt for connecting the fly cam and the overhead camshaft in which each valve installed in the engine is integrally installed. The timing belt is sucked into the engine. In order for the intake stroke to receive air and fuel, the compression stroke to compress the air and fuel, the explosion stroke to explode the compressed air and fuel, and the exhaust stroke to discharge the gas burned by the explosion to the outside can be operated correctly. To make adjustments.

따라서, 종래에는 상기 플라이 휠의 회전력이 오버 헤드 캠 샤프트에 전달될 수 있도록 내측에 순차적으로 다수개의 돌기를 형성하여 상기 돌기가 정확하게 플라이 휠을 지나면서 상기 오버 헤드 캠 샤프트를 회전시켜 상기한 각각의 행정에 오류가 발생하는 것을 방지 하였다.Therefore, in the related art, a plurality of protrusions are sequentially formed on the inner side so that the rotational force of the fly wheel can be transmitted to the overhead cam shaft, so that the protrusions accurately rotate the overhead cam shaft while passing the fly wheel. The error in the stroke was prevented from occurring.

그러나, 상기한 종래의 타이밍 벨트는 정확한 순서를 맞추어 설치해야 하기 때문에 반드시 숙련공이 설치를 하여야 하므로 설치가 용이하지 못한 문제가 있었고, 일단 설치를 한 후에는 커버를 덮어서 외부로부터의 이물질 침입등 외력으로부터 보호하기 때문에 외부에서 육안으로 타이밍 벨트의 마모 및 균열상태를 알 수 가 없어 교체시기를 정확하게 알지 못하므로, 차량의 주행중 타이밍 벨트의 절단으로 차량의 주행을 멈추게 되는 문제가 있었다.However, the above-described conventional timing belt had to be installed by a skilled worker because it must be installed in the correct order, and there was a problem in that the installation was not easy. Once installed, the cover was covered with an external force such as foreign matter intrusion from the outside. Because of the protection, the timing belt could not be seen from the outside with the naked eye, so the timing of replacement could not be known precisely. Therefore, the timing belt was cut off while the vehicle was running.

따라서, 본 발명은 상기한 종래의 문제점을 해결하기 위하여 창안한 것으로, 타이밍 벨트의 마모 및 균열등 주행에 부적합한 상태를 사용자에게 미리 경고할 수 있도록 하여 갑자기 차량의 주행을 멈추는 것을 방지할 수 있도록 한 타이밍 벨트의 교환시기를 알려주는 시스템을 제공하는 데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and it is possible to warn the user in advance of an unsuitable condition such as wear and cracking of the timing belt so as to prevent the vehicle from suddenly stopping running. The purpose is to provide a system for informing the timing of replacement of the timing belt.
