Description

전자식 벨트장력 조절장치{CONTROL SYSTEM FOR ELECTRONIC TYPE BELT TENSION}Electronic belt tension control device {CONTROL SYSTEM FOR ELECTRONIC TYPE BELT TENSION}

본 발명은 전자식 벨트장력 조절장치에 관한 것으로, 특히 자동차용 타이밍 벨트의 처짐을 감지하여 이를 비교판단하여 자동적으로 보정을 가할 수 있도록 한 전자식 벨트장력 조절장치에 관한 것이다.The present invention relates to an electronic belt tension control device, and more particularly, to an electronic belt tension control device that detects the deflection of the timing belt for an automobile and compares it and automatically applies the correction.

일반적으로, 타이밍 벨트는 엔진의 기동시 그 엔진의 구동력을 크랭크 축 풀리에서 물펌프 및 캠축등으로 전달시키는 기계부품요소로서, 엔진의 점화시기 조정 및 오일펌프 등의 보저기기의 구동에 사용된다.In general, the timing belt is a mechanical component element that transmits the driving force of the engine from the crankshaft pulley to the water pump and the camshaft when the engine is started, and is used for adjusting the ignition timing of the engine and driving the subsidiary equipment such as an oil pump.

이러한 타이밍 벨트는 그 회전에 따라 이완되어 벨트의 텐션이 변동되므로, 이 텐션의 변동에 따라 벨트의 장력을 자동적으로 조절할 수 있도록 자동텐셔너(auto-tensioner)가 설치되어 있다. 이는 도 3에 도시된 바와 같이, 벨트(10)의 일측면에 접촉되어 그 벨트(10)를 타측면으로 소정의 힘을 가압시켜 벨트(10)의 텐션을 조정하는 텐션풀리(20)와, 그 텐션풀리(20)가 연설되는 텐셔너암(30)을 밀어 링크 운동시키는 자동텐셔너(40)로 이루어진다.Since the timing belt is relaxed according to the rotation thereof and the tension of the belt varies, an auto-tensioner is installed to automatically adjust the tension of the belt according to the change of the tension. As shown in FIG. 3, the tension pulley 20 adjusts the tension of the belt 10 by contacting one side of the belt 10 to press the predetermined force to the other side of the belt 10. The tension pulley 20 is composed of an automatic tensioner 40 for pushing and linking the tensioner arm 30 to be spoken.

이러한 구조를 갖는 종래의 자동텐셔너는 그 텐션풀리(20)를 회전시키는 회전각에 따라 벨트(10)의 텐션이 변화되므로 그에 따라 항상 일정한 장력을 벨트(10)에 부가시키는 기능상의 어려움과, 그 텐션풀리(20)의 회전시 그 텐션풀리(20)가 이동하는 공간이 갖는 면적의 제약으로 공간활용성이 저하되는 문제점이 있었다.In the conventional automatic tensioner having such a structure, since the tension of the belt 10 changes according to the rotation angle of rotating the tension pulley 20, the functional difficulty of always adding a constant tension to the belt 10, and When the tension pulley 20 is rotated, there is a problem that space utilization is lowered due to the limitation of the area of the space in which the tension pulley 20 moves.

또한, 텐션풀리와 벨트의 외주면과의 마찰로 인해 에너지 소모 및 소음발생 등의 문제점이 있다.In addition, there is a problem such as energy consumption and noise generation due to friction between the tension pulley and the outer peripheral surface of the belt.

본 발명은 상기한 제반문제점을 감안하여 창출된 것으로서, 다음과 같은 목적을 갖는다.The present invention has been made in view of the above-mentioned problems, and has the following objects.

첫째, 텐션풀리의 설치공간 및 그 회전공간이 차지하는 면적을 생각하여 공간활용성을 증대시킬 수 있도록 한 전자식 벨트장력 조절장치를 제공하는 데 있다.First, it is to provide an electronic belt tension control device that can increase the space utilization in consideration of the space occupied by the installation space and the rotation space of the tension pulley.

둘째, 벨트와 풀리간의 가변되는 슬립량에 따라 적합한 장력 조절기능을 갖도록 한 전자식 벨트장력 조절장치를 제공하는 데 있다.Second, to provide an electronic belt tension control device having a suitable tension control function according to the variable slip amount between the belt and the pulley.

셋째, 텐션풀리와 벨트와의 마찰로 인한 소음발생을 차단시킬 수 있도록 한 전자식 벨트장력 조절장치를 제공하는 데 있다.Third, to provide an electronic belt tension control device that can block the noise generated by friction between the tension pulley and the belt.

넷째, 벨트의 장력을 조절하기 위한 유압에너지 및 마찰에너지의 낭비를 방지하도록 한 전자식 벨트장력 조절장치를 제공하는 데 있다.Fourth, to provide an electronic belt tension control device to prevent the waste of hydraulic energy and friction energy for adjusting the tension of the belt.

신축제어수단은 신축부재(300)의 내부공간에 마련되고 가열량에 비례하여 부피가 팽창하는 소정의 부피변화물질(400)과, 신출부재(300)의 내부공간에 수용되며 부피변화물질(400)에 소정의 열을 가해 부피를 변화시키는 열선(700)과, 전자제어유닛(이하, E.C.U(500)라 약칭함)으로부터 출력되는 전류를 인가받아 열선(700)으로 배터리(900)의 전류를 인가시키는 릴레이(600)를 구비한다.The expansion and contraction control means is provided in the internal space of the expansion and contraction member 300, the predetermined volume change material 400 is expanded in proportion to the amount of heating, and is accommodated in the internal space of the emerging member 300, the volume change material (400) ) Is applied to the heating wire 700 to change the volume by applying a predetermined heat and a current output from the electronic control unit (hereinafter, abbreviated as ECU 500) to receive the current of the battery 900 by the heating wire 700. And a relay 600 to be applied.

부피변화물질(400)은 열선(700)으로부터 발생되는 열에 의해서 부피가 가변되는 에테르 등을 채용한 것이 바람직하고, 신축부재(300)는 벨트(200)와의 면 접촉을 위해 그 외형이 제 1,2풀리(110,120)의 형상에 대응되게 형성됨이 바람직하다.Preferably, the volume change material 400 employs an ether or the like whose volume is changed by heat generated from the heating wire 700, and the expansion and contraction member 300 has a first and second shapes for surface contact with the belt 200. It is preferable that it is formed to correspond to the shape of the two pulleys (110,120).

이러한 구성을 갖는 본 발명의 작용을 다음과 같이 설명하기로 한다.The operation of the present invention having such a configuration will be described as follows.

제 1,2풀리(110,120)의 외주연으로 회전되는 벨트(200)가 이완되어 처지게 되면, 제 1,2풀리(110,120)의 회전속도와 벨트(200)의 회전속도에 어느 정도 차이가 발생하게 된다.When the belt 200 rotated to the outer circumference of the first and second pulleys 110 and 120 is relaxed and sag, a certain difference occurs in the rotation speed of the first and second pulleys 110 and 120 and the rotation speed of the belt 200. Done.

이에 따라 제 1센서부(810)와 제 2센서부(820)에서 각각 제 1풀리(110)와 벨트(200)의 회전속도에 따라 두 종료의 전압이 E.C.U(500)로 입력되고, 이 E.C.U(500)에서 그 두전압의 차를 검출하여 기준치와 비교 판단하여 하이 신호라고 판단되면, 소정의 전류가 릴레이(600)로 출력된다.Accordingly, the voltages of the two ends are input to the ECU 500 according to the rotational speeds of the first pulley 110 and the belt 200 in the first sensor unit 810 and the second sensor unit 820, respectively. When the difference between the two voltages is detected at 500 and determined to be compared with the reference value and determined to be a high signal, a predetermined current is output to the relay 600.

이어서, E.C.U(500)로부터 출력된 전류를 인가받은 릴레이(600)는 접점을 접속시켜 배터리(900)의 전류를 열선(700)으로 인가시켜 부피변환물질(400)을 팽창시키게 된다.Subsequently, the relay 600 receiving the current output from the E.C.U 500 connects the contact to apply the current of the battery 900 to the heating wire 700 to expand the volume conversion material 400.

이때, 열선(700)은 배터리(900)의 전류가 인가됨에 따라 자체 가열되어 신출부재(300)의 내부온도르 상승시키고, 부피변환물질(400)의 부피를 증대시켜 신축부재(300)를 외측으로 팽창시킨다.At this time, the heating wire 700 is self-heated as the current of the battery 900 is applied to increase the internal temperature of the emerging member 300, and increases the volume of the volume conversion material 400 to the outside of the stretchable member 300 Inflate

따라서, 외측으로 팽창된 신축부재(300)는 실질적으로 풀리의 부피를 팽창시키는 결과가 되므로, 벨트(200)의 장력이 조절된다.Therefore, since the elastic member 300 expanded outward is substantially the result of expanding the volume of the pulley, the tension of the belt 200 is adjusted.

한편, 벨트(200)의 장력이 어느 정도 팽팽하게 조절되면, 벨트(200)와 풀리의 회전속도의 차가 줄어드므로, E.C.U(500)에서 이를 기준치와 비교 판단하여 로우신호로 판정되어 릴레이(600)로 인가되는 전류가 차단된다.On the other hand, if the tension of the belt 200 is adjusted to some extent, the difference between the rotational speed of the belt 200 and the pulley is reduced, the ECU 500 is determined to compare with the reference value and determined as a low signal relay 600 Current is blocked.

이어서, 릴레이(600)가 오프 동작되어 열선(700)에 인가되는 배터리(900)의 전류가 차단되고, 열선(700)의 가열이 끝남에 따라 서서히 냉각되어 부피변환물질(400)의 부피가 축소된다.Subsequently, the relay 600 is turned off to cut off the current of the battery 900 applied to the heating wire 700, and gradually cools as the heating of the heating wire 700 ends, thereby reducing the volume of the volume conversion material 400. do.

따라서, 신축부재(300)의 외경이 축소되어 벨트(200)의 텐션력이 적당하게 조절된다.Therefore, the outer diameter of the elastic member 300 is reduced so that the tension force of the belt 200 is appropriately adjusted.

이상과 같이 설명한 본 발명은 벨트와 풀리의 회전속도의 차에 비례하여 텐션력이 조절되도록 한 것인바, 이에 따르면 다음과 같은 이점을 갖는다.The present invention as described above is to adjust the tension force in proportion to the difference in the rotational speed of the belt and the pulley, accordingly has the following advantages.

첫째, 종래 텐션풀리의 설치공간 및 그 회전공간이 차지하는 면적을 생략할 수 있으므로 공간활용성을 증대시킬 수 있다.First, the space occupied by the installation space and the rotation space of the conventional tension pulley can be omitted, thereby increasing the space utilization.

둘째, 벨트와 풀리간의 가변되는 슬립량에 따라 적합한 장력 조절기능을 갖는다.Second, it has a suitable tension control function according to the variable slip amount between the belt and the pulley.

셋째, 종래 텐션풀리와 벨트와의 마찰로 인한 소음발생을 차단시킬 수 있다.Third, it is possible to block the generation of noise due to friction between the tension pulley and the belt.

넷째, 벨트의 장력을 조절하기 위한 유압에너지 및 마찰에너지의 소모를 방지하는 유용한 효과를 갖는다.Fourth, it has a useful effect of preventing the consumption of hydraulic energy and friction energy for adjusting the tension of the belt.
