본 발명은 가변형 다이나믹 댐퍼에 관한 것으로, 상세하게는 차량에 진동을 감쇠시키도록 한 다이나믹 댐퍼를 차량고유의 진동특성에 따라 적절히 가변할 수 있도록 구성하므로써 각기 다른 진동특성을 갖는 다수의 차량에 적용할 수 있고, 진동에 대응한 다이나믹 댐퍼의 강성조절을 용이하게 할 수 있는 한편, 감쇠능을 향상시키도록 한 것이다.The present invention relates to a variable dynamic damper, and in particular, a dynamic damper for damping vibrations in a vehicle is configured to be appropriately changed according to the unique vibration characteristics of a vehicle, thereby being applicable to a plurality of vehicles having different vibration characteristics. It is possible to easily adjust the stiffness of the dynamic damper corresponding to vibration, and to improve the damping performance.

일반적으로 차량은 각 구성부품의 형상이나 각 부품간의 결합위치에 미세한 오차가 발생할 경우 차량의 주행성능과 관계없이 이상진동을 발생하게 되며, 이와같은 이상진동은 차량에 따라 각기 다른 고유의 진동을 갖는 한편, 그 크기에 있어서도 각 구성부품의 형상이나 각 부품간의 결합위치에 대한 오차에 따라 각기 다른 양상을 갖게 되는데, 이와같은 이상진동은 차량의 주행성능에는 직접 영향을 미치지 않으나 승차감을 저하시키는 원인이 되는 관계로, 차량의 생산공정 중 검사단계에서는 이상진동이 발생한 차량에 대해 트렁크 내부의 타이어 수납공간이나 엔진룸과 같이 외부로부터 은폐된 곳에 다이나믹 댐퍼를 설치하게 되며, 상기한 다이나믹 댐퍼는 일측에 구비한 탄성부재의 내부마찰에 의해 차량으로부터 발생한 이상진동을 상쇄시키므로써 이상진동을 감소시키거나 소멸하도록 하게 되며, 이와같이 차량으로부터 발생한 이상진동을 상쇄시키도록 한 다이나믹 댐퍼는 진동수 f=1/2π√K/F Hz(M:질량, K:강성)의 공식에서와 같이 탄성부재의 강성을 적절히 변화시키므로써 차량에 따라 각기 다른 고유의 진동수와 진폭을 갖는 진동특성에 대응하여 이상진동을 상쇄시키게 된다.In general, when a small error occurs in the shape of each component or the coupling position between the components, the vehicle generates abnormal vibrations regardless of the driving performance of the vehicle. Such abnormal vibrations have unique vibrations that vary from vehicle to vehicle. On the other hand, the size is different depending on the shape of each component or the error of the coupling position between each component, such an abnormal vibration does not directly affect the running performance of the vehicle, but causes a deterioration of the ride comfort In the inspection step of the production process of the vehicle, the dynamic damper is installed in a concealed place from the outside, such as a tire storage space in the trunk or an engine room, and the dynamic damper is provided at one side. The internal friction of an elastic member cancels out abnormal vibration generated from the vehicle. As a result, the dynamic damper which reduces or eliminates the abnormal vibration, and cancels the abnormal vibration generated from the vehicle, has the formula of the frequency f = 1 / 2π√K / F Hz (M: mass, K: stiffness). Likewise, by changing the rigidity of the elastic member appropriately, the abnormal vibration is canceled in response to vibration characteristics having different inherent frequencies and amplitudes depending on the vehicle.

한편, 상기한 바와 같이 차량의 이상진동을 상쇄시키도록 한 다이나믹 댐퍼는 제1도에 도시한 바와 같이 고무와 같은 탄성부재로 이루어진 원주형상의 완충재(35) 상부에 원판형상의 무게추(31)를 적충시킨 구조로 이루어져 무게추(31)의 가감에 따라 완충재(35)의 강성(stiffness)을 적절히 조절하므로써 이상진동을 감쇠시키게 되는데, 이와 같은 종래의 다이나믹 댐퍼(30)는 이상진동의 발생시 완충재(35)의 상부에 적충된 무게추(31)의 조합에 따라 완충재(35)의 강성을 조절하여야 하므로 차량의 진동특성에 따라 각기 다른 다수의 무게추(31)를 필요로 하게 되어 이상진동의 감쇠에 많은 비용이 소요되었으며, 완충재(35)의 강성에 대한 미세조절이 어려워 작업에 많은 시간과 인력이 소모되는 한편, 이상진동에 대한 감쇠능이 저하되는 등의 문제점이 따랐다.On the other hand, the dynamic damper for canceling the abnormal vibration of the vehicle as described above is a disk-shaped weight 31 on the upper portion of the cylindrical buffer material 35 made of an elastic member such as rubber as shown in FIG. The damper is damped by abnormally adjusting the stiffness of the shock absorbing material 35 according to the weight of the weight 31. The conventional dynamic damper 30 is a shock absorber when abnormal vibration is generated. Since the rigidity of the shock absorbing material 35 must be adjusted according to the combination of the weights 31 accumulated on the upper part of the upper part of the 35, a plurality of weights 31 different from each other are required according to the vibration characteristics of the vehicle. Attenuation was costly, and it was difficult to finely adjust the rigidity of the buffer material 35, which consumed a lot of time and manpower, and caused problems such as attenuation of abnormal vibrations.

본 발명에 의한 가변형 다이나믹 댐퍼는, 상기와 같은 종래의 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 차량에 이상진동이 발생할 경우 진동을 감쇠시키도록 한 다이나믹 댐퍼를 차량고유의 진동특성에 따라 적절히 가변할 수 있도록 구성하므로써 각기 다른 진동특성을 갖는 다수의 차량에 적용할 수 있고, 진동에 대응한 다이나믹 댐퍼의 강성조절을 용이하게 할 수 있으며, 진동에 대한 감쇠능을 향상시키도록 한 수단을 제공하는데 있는 것이다.The variable dynamic damper according to the present invention has been devised in view of the above-described conventional problems, and an object of the present invention is to provide a dynamic damper that attenuates vibration in the event of abnormal vibration in a vehicle according to the unique vibration characteristics of the vehicle. It can be applied to a large number of vehicles with different vibration characteristics by making it appropriately variable, and it is possible to easily adjust the rigidity of the dynamic damper corresponding to vibration, and to improve the damping ability of vibration. It is to provide.

상기와 같은 본 발명의 작용 및 효과를 설명하면, 본 발명에 의한 가변형 다이나믹 댐퍼(10)는, 받침판(9)의 상부에 부착된 고정링(6)을 통해 완충재(5)를 고정시키고, 상기한 완충재(5)의 관통공(4)을 통해 상부로 돌출된 나사봉(7)을 가압구(3)에 체결시킨 상태에서 통상구조의 다이나믹 댐퍼와 같이 진동이 발생한 위치와 인접한 차체패널(P)에 볼트로서 체결고정시키게 되며, 이와 같은 본 발명은 차량으로부터 이상진동이 발생할 경우 이상진동의 특성에 대응하도록 가압구(3)를 회동시켜 완충재(5)의 강성을 조절하여 이상진동을 감쇠시키게 되는데 예로써 완충재(5)의 강한 강성이 요구될 경우에는, 제4도에 도시한 바와 같이 나사봉(7)에 체결되어 완충재(5)의 관통공(4) 상부와 접한 가압구(3)를 화살표 방향으로 회동시키며, 이와 같이 가압구(3)를 회동시키게 되면 가압구(3)는 하부 방향으로 이동을 하는 한편, 쐐기 작용에 의해 완충재(5)를 내측으로부터 가압을 시키게 되므로써 완충재(5)는 강한 강성을 갖게 되며, 가압구(3)를 상부로 위치시키면 완충재(5)에 가해진 가압력이 해제되므로 가압구(3)의 적절한 회동에 따라 완충재(5)의 강성이 변화되는 한편, 이에 따라 차량의 진동을 감쇠시키게 되는 것이다.Referring to the operation and effect of the present invention as described above, the variable dynamic damper 10 according to the present invention, the buffer member 5 is fixed through the fixing ring 6 attached to the upper portion of the support plate 9, The body panel P adjacent to the position where vibration is generated, such as a dynamic damper having a normal structure, while the screw rod 7 protruding upward through the through hole 4 of the buffer member 5 is fastened to the pressure port 3. In the present invention, when the abnormal vibration occurs from the vehicle, the pressure port 3 is rotated to correspond to the characteristic of the abnormal vibration so as to damp the abnormal vibration by adjusting the rigidity of the shock absorbing material 5. For example, when the strong rigidity of the shock absorbing material 5 is required, as shown in FIG. 4, the pressure port 3 fastened to the threaded rod 7 and in contact with the upper portion of the through hole 4 of the shock absorbing material 5. Rotate in the direction of the arrow, and rotate the pressure port 3 in this manner. When the pressure port 3 moves downward, while the pressure member 3 pressurizes the cushioning material 5 from the inside by the wedge action, the cushioning material 5 has a strong rigidity, and the pressure port 3 is positioned upward. When the pressure applied to the shock absorbing material 5 is released, the rigidity of the shock absorbing material 5 is changed according to the proper rotation of the pressure port 3, and thus the vibration of the vehicle is attenuated.
