Description
본 고안은 자동차의 엔진에 장착되는 타이밍벨트의 위치 재조정이나 교환시기를 알려주는 신장경고장치에 관한 것으로, 특히 타이밍벨트의 길이가 그 기능을 수행할 수 있는 이상으로 늘어나면 이를 감지하여 운전자가 인식할 수 있도록 경고해 줌으로써 타이밍벨트의 장력이 저하됨에 따라 엔진 성능이 저하되는 것을 방지되도록 된 자동차용 타이밍벨트의 신장경고장치에 관한 것이다.The present invention relates to an extension warning device that informs the timing of repositioning or replacement of a timing belt mounted on an engine of a car. In particular, the driver recognizes when the length of the timing belt extends beyond its function. The present invention relates to an elongation warning device for a timing belt for automobiles, which prevents the engine performance from deteriorating as the tension of the timing belt decreases.
주지된 바와 같이, 자동차의 엔진에 장착되는 타이밍벨트는 크랭크 샤프트에 장착되어 있는 타이밍기어와 캠샤프트의 타이밍기어를 연결하는 벨트로서 오일펌프 등의 보조기기 구동에서 사용되는데, 기어와 맞물리는 이(Cog)가 설치되어 있다하여 코그벨트(이붙임벨트)라고도 불리우는 바, 타이밍벨트는 고무와 글라스 파이버 등 잘 신축되지 않는 섬유로 만들어지고 가볍고 조용하고 윤활도 불필요한 장점으로 왕복형 엔진에 널리 사용하고 있다.As is well known, the timing belt mounted on the engine of a vehicle is a belt connecting the timing gear mounted on the crankshaft and the timing gear of the camshaft, and is used in driving an auxiliary device such as an oil pump. Cog) is also called a cog belt, and timing belts are made of inflexible fibers such as rubber and glass fiber, and are widely used in reciprocating engines because of their lightness, quietness and unnecessary lubrication. .
상기 타이밍벨트는 동력전달기능을 제대로 수행하기 위해서는 장력이 일정압이상으로 유지되어야 하는데, 타이밍벨트는 결국은 고무재질로 되어 있으므로 일정시간 사용하게 되면 그 길이가 늘어나 장력이 저하되게 된다.In order to properly perform the power transmission function, the timing belt has to maintain tension above a certain pressure. Since the timing belt is made of rubber material, the length of the timing belt increases and its tension decreases when it is used for a certain time.
이를 방지하기 위해서 타이밍벨트의 장력을 일정하게 조정하는 텐셔너를 설치하고 있는데, 텐셔너의 개략적인 설치 상태는 도 2에 도시되어 있는 바, 이에 따르면, 아이들러(2)가 구비된 텐셔너(1)의 일측이 핀(3)을 매개로 엔진 몸체(도시안됨 ; 이하 동일)에 힌지고정되고, 다른 일측이 스프링(4)을 매개로 엔진 몸체에 탄력적으로 고정되며, 상기 텐셔너(1)의 아이들러(2)에 타이밍벨트(5)가 맞물려 있다.In order to prevent this, a tensioner for constantly adjusting the tension of the timing belt is installed. A schematic installation state of the tensioner is shown in FIG. 2, and accordingly, one side of the tensioner 1 having the idler 2 is provided. This pin (3) is hinged to the engine body (not shown; the same below), the other side is elastically fixed to the engine body via the spring (4), the idler (2) of the tensioner (1) Timing belt 5 is engaged.
이에 따르면, 상기 스프링(4)이 일정압력으로 텐셔너(1)를 당기게 되므로, 이 텐셔너(1)의 아이들러(2)에 맞물린 타이밍벨트(5)가 일정압력으로 당겨지게 되어, 타이밍벨트(5)가 신장되더라도 장력이 규정압 이상으로 유지되게 된다.According to this, since the spring 4 pulls the tensioner 1 at a constant pressure, the timing belt 5 engaged with the idler 2 of the tensioner 1 is pulled at a constant pressure, and thus the timing belt 5 Even if is stretched, the tension is maintained above the specified pressure.
그러나, 타이밍벨트(5)의 신장이 연속적으로 이루어지면 스프링(4)에 의해 당겨지며 회전되는 텐셔너(1)의 이동이 일정상태에서 더 이상 이루어지지 못하므로 타이밍벨트(5)의 장력을 일정하게 조정하는 기능이 상실되게 되는데, 종래에는 이를 감지하여 운전자가 인식하도록 경고하는 장치가 마련되지 못하여 타이밍벨트(5)를 일정기간 사용한 후 임의적으로 타이밍벨트의 위치를 재조정하거나 교체하고 있는 바, 이로 인하여 타이밍벨트(5)의 위치를 재조정이나 교체하는 시기가 적절하게 이루어지지 못하므로 엔진성능이 저하되고, 각 기기들의 작동이 상호 적절하게 연동되지 못하므로 엔진의 수명이 단축되는 문제가 있었다.However, when the timing belt 5 is continuously stretched, the tension of the timing belt 5 is kept constant since the movement of the tensioner 1, which is pulled and rotated by the spring 4, is no longer performed in a constant state. The function of adjusting is lost. In the related art, there is no device for detecting and warning the driver so that the timing belt 5 is arbitrarily repositioned or replaced after using the timing belt 5 for a certain period of time. Since the timing of the timing belt 5 is not properly adjusted or replaced, the engine performance is degraded, and the operation of each device is not properly interlocked with each other, thereby reducing the engine life.
이에 본 고안은 상기와 같은 문제를 해소하기 위하여 안출된 것으로, 타이밍벨트의 길이가 그 기능을 수행할 수 있는 이상으로 늘어나면 이를 감지하여 운전자가 인식할 수 있도록 경고해 줌으로써 벨트의 장력이 저하됨에 따라 엔진 성능이 저하되는 것이 방지되도록 하는 자동차용 타이밍벨트의 신장경고장치를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and when the length of the timing belt is extended beyond the function of the function, the belt tension is lowered by detecting and warning the driver to recognize it. Accordingly, an object of the present invention is to provide an elongation warning device for a timing belt for automobiles to prevent deterioration of engine performance.

상기와 같은 목적을 달성하기 위한 본 고안은, 텐셔너의 이동을 감지하는 리미트 스윗치와, 이 리미트 스윗치에 의해 ON/OFF 제어되는 발광부재로 이루어진 구조로 되어 있다.The present invention for achieving the above object is a structure consisting of a limit switch for detecting the movement of the tensioner, and a light emitting member that is ON / OFF controlled by this limit switch.
이하 본 고안을 첨부된 예시도면에 의거하여 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안에 따른 신장경고장치의 개략적인 구성도인 바, 종래 기술에 따른 도 2와 동일한 부위에는 동일한 참조부호를 붙이면서 그 설명을 생략한다.Figure 1 is a schematic configuration diagram of the kidney warning apparatus according to the present invention, the same parts as in Figure 2 according to the prior art while attaching the same reference numerals will be omitted.
이에 따르면, 아이들러(2)가 구비된 텐셔너(1)의 일측이 핀(3)을 매개로 엔진 몸체(도시안됨 ; 이하 동일)에 힌지고정되고, 다른 일측이 스프링(4)을 매개로 엔진 몸체에 탄력적으로 고정되며, 상기 텐셔너(1)의 아이들러(2)에 타이밍벨트(5)가 맞물려 지고, 텐셔너(1)의 최대 이동위치에 리미트 스윗치(6)가 엔진 몸체에 설치되고, 이 리미트 스윗치(6)에 연결된 발광부재(7)는 운전자가 인식하기 용이한 지점에 설치된다.According to this, one side of the tensioner 1 with the idler 2 is hinged to the engine body (not shown; the same below) via the pin 3, and the other side is the engine body via the spring 4. Is fixed elastically to the idler (2) of the tensioner (1), the timing belt (5) is engaged, the limit switch (6) is installed in the engine body at the maximum movement position of the tensioner (1), the limit switch The light emitting member 7 connected to 6 is installed at a point that is easy for the driver to recognize.
따라서, 타이밍벨트(5)의 신장이 연속적으로 이루어져 스프링(4)에 의해 텐셔너(1)가 최대 이동위치로 이동되면 텐셔너(1)의 선단이 리미트 스윗치(6)에 접촉되어 리미트 스윗치(6)가 ON으로 되고, 이에 따라 발광부재(7)에 전원이 공급되어 발광부재(7)가 발광하게 되므로 운전자가 텐셔너의 위치 재조정, 혹은 교환시기를 정확히 알 수 있게 된다.Therefore, when the tension belt 1 is continuously extended and the tensioner 1 is moved to the maximum movement position by the spring 4, the tip of the tensioner 1 is in contact with the limit switch 6 to limit the switch 6. Is turned on, and thus power is supplied to the light emitting member 7 so that the light emitting member 7 emits light, so that the driver can accurately know when to reposition or replace the tensioner.
이상 상기한 바와 같은 본 고안에 따르면, 텐셔너의 위치를 감지하여 텐셔너의 위치 재조정과 타이밍벨트의 교환시기를 운전자가 정확하게 인식할 수 있도록 되므로 타이밍벨트의 장력저하로 인한 엔진 성능 저하가 방지됨과 더불어, 각 기기들의 작동이 상호 적절하게 연동되지 못하므로 엔진의 수명이 단축되는 것이 방지되는 효과가 있다.According to the present invention as described above, the driver can accurately recognize the position of the tensioner and the timing of replacement of the timing belt by detecting the position of the tensioner, so that the engine performance is prevented from being deteriorated due to the tension belt tension reduction. Since the operation of each device is not properly interlocked with each other, there is an effect that the life of the engine is shortened.
또한, 타이밍벨트의 이용효율이 증가되므로 타이밍벨트의 교환비용이 절감되는 효과도 기대된다.In addition, since the utilization efficiency of the timing belt is increased, the effect of reducing the replacement cost of the timing belt is also expected.
