Description

자동차의 구동벨트 장력조절장치Driving belt tensioning device of automobile

본 발명은 자동차의 크랭크 샤프트 풀리와 워터 펌프 풀리 및 알티네이터의 구동벨트에 관한 것으로, 특히 구동벨트를 오랫 동안에 사용함으로 인해 구동벨트의 장력이 느슨하게 이완되었을 때에 구동벨트의 장력을 용이하면서도 정밀하게 조절할 수 있도록 된 자동차의 구동벨트 장력조절장치에 관한 것이다.The present invention relates to a crankshaft pulley of an automobile and a drive belt of a water pump pulley and an altiser. In particular, when the tension of the drive belt is relaxed loosely by using the drive belt for a long time, And more particularly to a driving belt tension adjusting device for a motor vehicle.

일반적으로 자동차의 엔진 구동동력은 차륜을 회전시켜 전진이나 후진주행이 이루어지도록 하는 이외에도 여러 가지 부대장치들을 구동시키는 구동원으로도 사용되고 있는 바, 상기와 같이 엔진의 구동력을 동력으로 사용하는 부대장치로서는 예컨대 알티네이터와 워터 펌프 등이 있다.Generally, the engine driving power of an automobile is used as a driving source for driving various auxiliary devices in addition to forward and backward traveling by rotating the wheels. As an auxiliary device using the driving force of the engine as a power source as described above, There are altinators and water pumps.

그리고 상기한 부대장치들은 엔진과 벨트를 매개로 연결되어, 엔진의 구동력을 전달받아 작동되게 되어 있는 데, 도 1은 종래 기술에 따라 엔진의 크랭크 샤프트 풀리에 워터 펌프 풀리와 알티네이터가 구동벨트를 매개로 동력을 전달받을 수 있게 연결된 상태의 측면도이다.1 is a perspective view of a crankshaft pulley of an engine according to the prior art in which a water pump pulley and an altinator are connected to a drive belt via an engine and a belt, And is a side view in a state in which the power transmission is mediated.

즉 엔진의 크랭크 샤프트 풀리(101)와 인접하게 배열된 워터 펌프 풀리(102) 및 알티네이터(103)는 구동벨트(104)를 매개로 서로 연결되어 있다.That is, the water pump pulley 102 and the altenator 103 arranged adjacent to the crankshaft pulley 101 of the engine are connected to each other through the drive belt 104.

그리고 상기와 같이 구동벨트를 매개로 엔진의 동력을 전달받아 각 부대장치들이 작동될 때에 구동벨트에 항상 적절한 장력이 유지되지 못하면 엔진의 동력전달이 원활하게 이루어지지 않게 되므로, 상기 구동벨트에는 항상 적절한 장력이 유지되도록 해야 한다.If the appropriate tension is not always maintained on the drive belt when the auxiliary units are operated by receiving the power of the engine through the drive belt as described above, the power transmission of the engine is not smoothly performed. Tension should be maintained.

그런데 구동벨트를 매개로 동력을 전달받는 동력전달계통에서는 장시간이 경과되면 구동벨트가 장력 때문에 느슨하게 이완되면서 초기장력이 유지되지 못하고 되는 데, 이 경우에 구동벨트의 장력을 조절하기 위해 종래에도 장력조절장치가 구비되어 있었다.However, in the power transmission system that receives power through the drive belt, when the elapsed time elapses, the initial tension is not maintained because the drive belt loosens due to the tension. In this case, in order to adjust the tension of the drive belt, Device.

즉 상기 알티네이터는 지지로드(105)에 형성된 장공(106)을 통해 끼워지는 보울트(107)를 매개로 한쪽 선단부가 엔진의 실린더 블록에 체결되고, 다른쪽 선단부도 체결보울트(108)를 매개로 실린더 블록에 체결된 구조로 되어, 구동벨트의 장력을 조절하기 위해 상기 2개의 보울트를 풀고난 다음에 지렛대(109)를 사용해서 알티네이터를 회동시켜 구동벨트의 장력을 조절하고 나서 다시 상기 보울트들을 단단하게 체결시켜 주게 되어 있다.That is, the above-mentioned altenator is fastened to the cylinder block of the engine via the bolt 107 inserted through the elongated hole 106 formed in the support rod 105, and the other end is also fastened to the cylinder block of the engine via the fastening bolt 108 After the two bolts are loosened to adjust the tension of the drive belt, the tensioner of the drive belt is adjusted by rotating the altimeter using the lever 109, So that they are firmly fastened.

상기와 같은 종래의 장력조절구조에서는 알티네이터의 체결 보울트를 풀고나서 다시 조여주어야 하는 번거러움이 있었고, 또 지렛대를 이용하여 장력을 원하는 만큼 정밀하게 조절할 수 없다고 하는 결점이 있었다.In the conventional tension adjusting structure as described above, it is troublesome to unfasten the fastening bolt of the altenator and tighten it again, and there is also a disadvantage that the tension can not be precisely adjusted as desired using the lever.

이에 본 발명은 상기한 종래의 결점을 해소하기 위해 안출된 것으로, 알티네이터에 인접되게 설치된 장력조절보울트를 사용해서 구동벨트의 장력을 용이하면서도 정밀하게 조절할 수 있도록 된 자동차의 구동벨트 장력조절장치를 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a driving belt tension adjusting device for an automobile which can easily and precisely adjust a tension of a driving belt by using a tension adjusting bolt The purpose is to provide.
