Description
본 고안은 자동차의 댐퍼풀리에 관한 것으로, 특히 내측링과 외측링사이의 댐퍼고무링에 인너매스를 추가하여 2개의 공진주파수대역에서 비틀림진동을 효과적으로 저감시킬 수 있도록 된 인너매스를 이용한 2중댐퍼풀리에 관한 것이다.The present invention relates to a damper pulley of an automobile, and in particular, a double damper using inner mass that effectively reduces torsional vibration in two resonant frequency bands by adding inner mass to the damper rubber ring between the inner ring and the outer ring. It's about pulleys.
종래 자동차의 크랭크 샤프트의 끝부위에는 에어컨의 컴프레셔나 워터 펌프를 구동시키기 위해 벨트를 에어컨의 컴프레셔나 워터 펌프의 구동축과 벨트를 매개로 연결된 풀리가 장착되어 있는데, 이와 같은 풀리에는 비틀림진동을 저감시키기 위해 댐퍼가 부착되어 있다.The conventional end of the crankshaft of the car is equipped with a pulley connected to the drive shaft of the air conditioner compressor or water pump and the belt to drive the compressor or water pump of the air conditioner, such a pulley to reduce the torsional vibration Damper is attached.
도 1은 종래 기술에 따라 댐퍼가 장착된 풀리를 도시한 것인바, 즉 풀리(11)가 크랭크 샤프트에 끼워져 장착되는 내측링(12)과, 벨트가 걸려지는 외측링(13) 및, 이 외측링(13)과 내측링(12)사이에 개재된 고무댐퍼(14)를 갖춘 구조로 되어있다.1 shows a pulley equipped with a damper according to the prior art, that is, the inner ring 12 in which the pulley 11 is fitted by being fitted to the crankshaft, the outer ring 13 on which the belt is caught, and the outer side thereof. The rubber damper 14 is interposed between the ring 13 and the inner ring 12.
이에 따라 풀리의 구동시에 상기 고무댐퍼(14)가 비틀림진동을 적절히 흡수해서 저감시켜주게 되어 있다.Accordingly, the rubber damper 14 appropriately absorbs and reduces the torsional vibration when the pulley is driven.
그런데 상기한 종래의 댐퍼풀리는 외측링의 질량과 고무댐퍼의 탄성계수가 각각 이미 결정지워져 있기 때문에 단지 하나의 공진진동수 대역에 대해서만 비틀림진동을 흡수하여 저감시킬 수 있고, 다른 주파수대역에 대해서는 진동흡수효과가 미흡하기 때문에 그 사용상의 범위가 좁고, 또 전체 대역에 걸려서 진동을 낮추어 주기에는 미흡하다고 하는 결점이 있었다.However, since the mass of the outer ring and the elastic modulus of the rubber damper have already been determined, the conventional damper pulley can absorb and reduce torsional vibration only for one resonance frequency band, and absorb vibration for another frequency band. Because of the shortcomings, the range of use is narrow, and there is a shortcoming that it is insufficient to lower the vibration by covering the entire band.
이에 본 고안은 상기한 결점을 해소하기 위해 안출된 것으로, 풀리의 구동속도에 따라 진동흡수계의 질량이 서로 다른 2개의 질량으로 가변되도록하여 2개의 공진주파수대역에 대해 튜닝할 수 있도록 함으로써 전체의 주파수대역에 걸쳐서 진동을 효과적으로 저감시킬 수 있도록 된 인너매스를 이용한 댐퍼풀리를 제공함에 그 목적이 있다.The present invention has been devised to solve the above-mentioned drawbacks, and the mass of the vibration absorber is varied to two different masses according to the driving speed of the pulley so that it can be tuned to two resonance frequency bands. It is an object of the present invention to provide a damper pulley using inner mass that can effectively reduce vibrations over a frequency band.

상기한 바의 목적을 달성하기 위한 본 고안은, 크랭크 샤프트에 끼워져 장착되는 내측링과, 벨트가 걸려지는 외측링 및, 이 외측링과 내측링사이에 개재되어 일체로 부착된 고무댐퍼를 갖춘 댐퍼풀리에 있어서, 상기 고무댐퍼에 원주방향으로 일정한 각변위를 두고 다수개의 인너매스가 외측링에 인접해서 일체로 부착된 것을 특징으로 하는 구조로 되어 있다.The present invention for achieving the above object is a damper having an inner ring fitted to the crankshaft, an outer ring on which the belt is caught, and a rubber damper interposed integrally between the outer ring and the inner ring. In the pulley, a plurality of inner masses are integrally attached adjacent to the outer ring with a constant angular displacement in the circumferential direction to the rubber damper.
이하 본 고안의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안에 따른 인너매스를 이용한 2중댐퍼풀리의 정면도인 바, 즉 풀리(1)가 크랭크 샤프트에 끼워져 장착되는 내측링(2)과, 벨트가 걸려지는 외측링(3) 및, 이 외측링(3)과 내측링(2)사이에 개재된 고무댐퍼(4)를 갖춘 구조로 되어 있다.Figure 2 is a front view of the double damper pulley using the inner mass according to the present invention, that is, the inner ring (2) and the outer ring (3) to which the pulley (1) is fitted and fitted to the crankshaft, The rubber damper 4 is interposed between the outer ring 3 and the inner ring 2.
그리고 상기 고무댐퍼(4)는 원주방향으로 일정한 각변위를 두고 다수개의 고무댐퍼(4)가 외측링(3)에 인접해서 일체로 부착되어 있다.The rubber dampers 4 are integrally attached to the rubber dampers 4 adjacent to the outer ring 3 with a constant angular displacement in the circumferential direction.
이에 따라 풀리의 저속구동시에는 상기 외측링(3)과 고무댐퍼(4)만으로 된 진동흡수계가 풀리의 구동시에 발생하는 비틀림진동을 적절히 흡수해서 고주파수대역의 진동을 저감시킬 수 있게 된다.Accordingly, during low speed driving of the pulley, the vibration absorbing system composed of only the outer ring 3 and the rubber damper 4 absorbs the torsional vibration generated when the pulley is driven, thereby reducing the vibration of the high frequency band.
또 풀리의 고속구동시에는 상기 고무댐퍼(4)가 원심력에 의해 외측링(3)쪽으로 붙게 되어, 외측링의 질량이 커지게 되고, 이에 따라 외측링(3)과 인너매스(5) 및 고무댐퍼(4)가 이루어진 진동흡수계가 상대적으로 저주파수대역의 진동을 적절히 흡수해서 저감시킬 수 있게 되므로, 결국에는 전체 주파수대역에 걸쳐서 폭넓게 비틀림진동을 흡수해서 저감시킬 수 있게 되는 것이다.In addition, when the pulley is driven at high speed, the rubber damper 4 is attached to the outer ring 3 by centrifugal force, and the mass of the outer ring is increased, so that the outer ring 3, inner mass 5 and rubber Since the vibration absorbing system provided with the damper 4 can relatively absorb and reduce the vibration of the low frequency band, the torsional vibration can be absorbed and reduced widely over the entire frequency band.
이상 설명한 바와 같이 본 고안에 따른 인너매스를 이용한 2중댐퍼풀리에 의하면, 풀리의 구동시에 발생하는 비틀림진동을 저주파수대역 및 고주파수대역에 걸쳐서 전체적으로 폭넓게 흡수하여 저감시킬 수 있는 효과가 있다.As described above, according to the double damper pulley using the inner mass according to the present invention, there is an effect that the torsional vibration generated when the pulley is driven can be broadly absorbed and reduced throughout the low frequency band and the high frequency band.
