본 발명은 자동차의 타이밍 벨트 장력 조절용 텐셔너에 관한 것으로서, 텐셔너에 의하여 조절되는 타이밍 벨트의 가감 장력치를 표시할 수 있도록 한 자동차의 타이밍 벨트 장력 조절용 텐셔너에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tensioner for adjusting timing belt tension of an automobile, and more particularly to a tensioner for adjusting timing belt tension of an automobile, which is capable of displaying an acceleration / decrease tension value of a timing belt controlled by a tensioner.

통상적으로 자동차용 엔진의 크랭크샤프트 스프로켓(30)과, 캠샤프트 스프로켓(28)과, 오일펌프 스프로켓(32)과, 텐셔너(10b)는 첨부한 도 2에 도시한 바와 같이 타이밍 벨트(12)로 감아져 연결되어 있고, 상기 텐셔너(10b)의 조작으로 상기 타이밍 벨트(12)의 장력을 조절할 수 있게 되어 있다.Typically, the crankshaft sprocket 30, the camshaft sprocket 28, the oil pump sprocket 32, and the tensioner 10b of the automotive engine are attached to the timing belt 12 as shown in FIG. It is wound and connected, and the tension of the timing belt 12 can be adjusted by the operation of the tensioner 10b.

상기 텐셔너(10b)에는 엔진본체에 볼팅으로 고정되는 고정단(14)과, 볼트가 삽입되는 슬롯홀(20)을 갖는 조절단(16)이 일체로 형성되어 있다.The tensioner 10b is integrally formed with a fixed end 14 fixed to the engine body by bolting and an adjusting end 16 having a slot hole 20 into which a bolt is inserted.

따라서, 텐셔너(10b)의 고정단(14)과 조절단(16)의 슬롯홀(20)에서 볼트(18)를 풀어 텐셔너(10b)를 이동시키는 바, 이때 조절단(16)의 슬롯홀(20)을 따라서 볼트(18)는 고정된 상태로 슬라이드되며, 다시 상기 텐셔너(10b)의 고정단(14)과 조절단(16)의 슬롯홀(20)에 볼트(18)를 체결시킴으로써, 텐셔너(10b)에 감긴 타이밍 벨트(12)의 장력이 조절되어진다.Accordingly, the tensioner 10b is moved by releasing the bolt 18 from the fixed end 14 of the tensioner 10b and the slot hole 20 of the adjusting end 16 to move the tensioner 10b. Along the 20, the bolt 18 slides in a fixed state, and again by tightening the bolt 18 to the fixed end 14 of the tensioner 10b and the slot hole 20 of the control end 16, the tensioner The tension of the timing belt 12 wound around 10b is adjusted.

그러나, 상기와 같이 1)고정용 볼트를 품2)텐셔너 이동3)고정용 볼트 조임4)타이밍벨트의 장력확인 등의 순서로 작업을 하지만, 원하는 장력으로 타이밍벨트의 장력이 조절되지 않으면 상기와 같은 순서를 다시 반복해야 하는 불편하고 번거로운 점이 있으며, 특히, 텐셔너의 위치를 1∼2mm 정도만 이동시켜도 장력이 5∼10㎏f 정도가 변동되기 때문에 장력조절시 세심한 주위가 필요하여 정확하게 장력을 조절하는데 어려운 점이 있었다.However, as above, 1) the fixing bolt 2) tensioner moving 3) Fastening fixing bolt 4) In order to check the tension of the timing belt, etc., but if the tension of the timing belt is not adjusted to the desired tension, it is inconvenient and cumbersome to repeat the above steps again. Even if only the degree of movement of the tension is fluctuated by about 5 ~ 10㎏f, it is difficult to precisely adjust the tension because a careful surroundings are required when adjusting the tension.

따라서, 본 발명은 상기와 같은 점을 감안하여 제안된 것으로서, 텐셔너를 이동시켜 타이밍벨트의 장력을 조절할때, 조절된 장력치를 표시할 수 있도록 텐셔너의 조절단에 눈금 역할을 하는 굴곡홈을 다수개 형성하는 동시에 이 굴곡홈에 맞물리는 조절기구를 엔진본체에 장착하여서 된 자동차의 타이밍 벨트 장력 조절용 텐셔너를 제공하는데 그 목적이 있다.Therefore, the present invention has been proposed in view of the above, and when the tensioner is moved to adjust the tension of the timing belt, a plurality of bending grooves serving as graduations on the adjustment end of the tensioner can be displayed to display the adjusted tension value. It is an object of the present invention to provide a tensioner for adjusting the tension of a timing belt of an automobile, which is formed by attaching an adjustment mechanism to the bent groove at the same time.

The adjustment mechanism 24 has an elliptical shape in the front case of the engine to retain elastic force. It is mounted in a bent state.

여기서 본 발명을 실시예로서, 첨부한 도면을 참조로 더욱 상세하게 설명하면 다음과 같다.Herein, the present invention will be described in more detail with reference to the accompanying drawings.

첨부한 도 1은 본 발명에 따른 자동차의 타이밍 벨트 장력 조절용 텐셔너를 나타내는 사시도로서, 도면부호 10a는 개선된 본 발명의 텐셔너를 나타낸다.1 is a perspective view showing a tensioner for adjusting the timing belt tension of an automobile according to the present invention, wherein reference numeral 10a denotes an improved tensioner of the present invention.

상기 텐셔너(10a)는 타이밍 벨트가 감겨지는 원통부분과 이 원통부분의 일측에 일체로 부착되어진 고정단(14)과 조절단(16)으로 구성되어 있고, 좀 더 상세하게는 상기 고정단(14)에는 볼팅용 홀이 형성되어 있고, 조절단(16)에는 슬롯홀(20)이 형성되어 있다.The tensioner 10a includes a cylindrical portion on which the timing belt is wound, and a fixed end 14 and an adjusting end 16 integrally attached to one side of the cylindrical portion, and more specifically, the fixed end 14. Bolting hole is formed in the, and the adjusting end 16 is formed with a slot hole (20).

특히, 상기 텐션너(10a)의 조절단(16) 외주면에는 다수의 굴곡홈(22a)이 형성되고, 이 굴곡홈(22a)의 바로 밑쪽 표면에는 장력의 가감 표시를 위한 눈금(26)이 새겨지게 된다.In particular, a plurality of bending grooves 22a are formed on the outer circumferential surface of the adjusting end 16 of the tensioner 10a, and a scale 26 for marking the acceleration and deceleration of the tension grooves 10a is engraved. You lose.

한편, 상기 텐셔너(10a)의 조절단(16)에 형성된 굴곡홈(22a)에 맞물리는 굴곡홈(22b)을 갖는 조절기구(24)를 엔진의 프론트케이스에 설치하게 되는 바, 상기 조절기구(24)를 더욱 상세하게 설명하면 다음과 같다.On the other hand, the adjustment mechanism 24 having a bending groove 22b that engages with the bending groove 22a formed in the adjusting end 16 of the tensioner 10a is installed in the front case of the engine, the adjusting mechanism ( 24 will be described in more detail as follows.

상기 조절기구(24)는 양쪽단이 볼팅홀을 갖는 장착단으로 형성되고 중앙부 일정부위에는 상기 조절단(16)의 굴곡홈(22a)에 맞물리는 굴곡홈(22b)이 형성된 판형의 형상으로서, 자체적인 탄성력을 보유하도록 엔진의 프론트케이스에는 타원형으로 휘어지게 하여 볼팅 장착되어진다.The adjustment mechanism 24 is formed as a mounting end having a bolting hole at both ends and a plate-shaped shape having a bending groove 22b engaged with the bending groove 22a of the adjusting end 16 at a predetermined portion of the central portion. The front case of the engine is bolted in an oval shape to retain its elastic force.

좀 더 상세하게는, 상기 조절기구(24)의 굴곡홈(22b)의 표면에는 기준이 되는 장력표시 눈금이 표시되어진다.More specifically, the tension display scale as a reference is displayed on the surface of the bending groove 22b of the adjusting mechanism 24.

따라서, 타이밍벨트(12)의 장력을 조절하고자 할 때에는 상술한 바와 같이, 텐셔너(10a)의 고정단(14)과 조절단(16)의 볼트(18)를 풀고, 텐셔너(10a)를 이동시키는 바, 이때 조절단(16)의 굴곡홈(22a)이 상기 조절기구(24)의 굴곡홈(22b)을 따라 맞물림 이동을 하게 된다.Accordingly, when the tension of the timing belt 12 is to be adjusted, as described above, the fixing end 14 of the tensioner 10a and the bolt 18 of the adjusting end 16 are loosened to move the tensioner 10a. At this time, the bending groove 22a of the adjusting end 16 is engaged with the bending groove 22b of the adjusting mechanism 24.

이에따라, 상기 조절단(16)의 장력 표시 눈금(26)이 상기 기준이 되는 굴곡홈(22b)의 장력표시눈금과 일치되면, 타이밍벨트(12)의 장력이 용이한 수준으로 조절된 상태가 되어진다.Accordingly, when the tension display scale 26 of the adjustment stage 16 coincides with the tension display scale of the bending groove 22b as the reference, the tension of the timing belt 12 is adjusted to an easy level. Lose.

물론, 상기 타이밍벨트(12)의 장력을 더욱 크게 또는 작게 할 때에는 상기 조절단(16)의 장력 표시 눈금(26)이 상기 기준이 되는 굴곡홈(22b)의 장력표시눈금보다 증가 또는 감소방향으로 넘어가게 함으로써, 타이밍벨트의 장력조절상태를 쉽게 인식할 수 있게 된다.Of course, when the tension of the timing belt 12 is made larger or smaller, the tension display scale 26 of the adjustment stage 16 is increased or decreased in the direction of increasing or decreasing the tension display scale of the bending groove 22b. By passing it, the tension control state of the timing belt can be easily recognized.

이상에서 본 바와 같이 본 발명에 따른 자동차의 타이밍벨트 장력 조절용 텐셔너에 의하면, 텐셔너를 이동시켜 타이밍벨트의 장력을 조절할때, 조절된 장력치를 표시할 수 있도록 함으로써, 작업자는 타이밍벨트의 장력조절상태를 쉽게 인식할 수 있어 편리한 점 있다.As described above, according to the tensioner for timing belt tension adjustment of an automobile according to the present invention, when the tensioner is moved to adjust the tension of the timing belt, the operator can display the adjusted tension value so that the operator can adjust the tension belt tension state. It is easy to recognize and has a convenience.
