Description

자동차용 다이나믹 댐퍼{Dynamic damper for a motor vehicle}Dynamic damper for a motor vehicle

본 발명은 자동차의 주행시 각종 부품들에서 발생되는 진동 및 소음이 차체를 통해 자동차의 다른 부분으로 전달되는 것을 방지하기 위한 다이나믹 댐퍼에 관한 것이다.The present invention relates to a dynamic damper for preventing vibrations and noises generated from various components during driving of a vehicle from being transmitted to other parts of the vehicle through the vehicle body.

일반적으로 자동차가 고속으로 주행할 때, 자동차에서는 엔진이나 이 엔진에서 발생된 동력을 바퀴로 전달하는 동력 전달계에서 진동 및 소음이 크게 발생된다. 따라서, 이러한 진동의 발생을 방지하거나 억제하기 위한 다이나믹 댐퍼가 자동차의 진동 발생 부품들에 설치되어 있다.In general, when the vehicle travels at a high speed, the vehicle generates a lot of vibration and noise in the engine or a power transmission system that transmits the power generated by the engine to the wheels. Therefore, a dynamic damper for preventing or suppressing the occurrence of such vibrations is provided in the vibration generating parts of the automobile.

도 1은 통상적으로 사용되고 있는 다이나믹 댐퍼의 일예를 도시한 것이다.1 illustrates an example of a dynamic damper that is commonly used.

도시된 바와 같이, 다이나믹 댐퍼는 질량체(1)와 이 질량체(1)의 양측에 고정된 한 쌍의 탄성체(2)와 한 쌍의 탄성체(2)를 차체4에 고정하는 한 쌍의 브라켓(3)을 포함하고 있다. 한 쌍의 탄성체(2)는 고무 재질로 이루어져 있다.As shown, the dynamic damper includes a mass body 1, a pair of elastic bodies 2 fixed to both sides of the mass body 1, and a pair of brackets 3 fixing the pair of elastic bodies 2 to the vehicle body 4. ) Is included. The pair of elastic bodies 2 is made of a rubber material.

이러한 구성으로 이루어진 다이나믹 댐퍼는 질량체(1)의 중량 및 탄성체(2)의 탄성 계수와 댐핑 계수에 의해 결정되는 진동수가 진동이 발생되는 부품의 고유 진동수에 대응되도록 설정된다. 이에 따라 부품으로부터 진동이 발생되면 다이나믹 댐퍼에서 공진이 발생됨으로써, 부품의 진동은 상쇄 및 저감된다.The dynamic damper having such a configuration is set so that the frequency determined by the weight of the mass 1 and the elastic and damping coefficients of the elastic body 2 corresponds to the natural frequency of the component in which the vibration is generated. Accordingly, when vibration is generated from the component, resonance occurs in the dynamic damper, thereby canceling and reducing the vibration of the component.

그런데, 진동이 발생되는 부품의 진동수는 부품의 종류에 따라서 상이한 값을 가지며, 동일한 부품이라도 설치되는 자동차의 특성에 따라 달라지게 된다.By the way, the frequency of the part in which the vibration is generated has a different value according to the type of the part, and even the same part will vary depending on the characteristics of the vehicle installed.

그러나, 상기와 같은 종래의 다이나믹 댐퍼는 그 진동수가 고정되어 있기 때문에 부품의 종류 및 부품이 설치되는 자동차의 특성에 대응하기 위하여, 다양한 진동수를 가진 다양한 종류의 다이나믹 댐퍼가 필요한 단점이 있다.However, the conventional dynamic damper as described above has a disadvantage in that various types of dynamic dampers having various frequencies are required in order to correspond to the type of parts and the characteristics of the vehicle in which the parts are installed because the frequency is fixed.

본 발명은 상기와 같은 점을 감안하여 안출된 것으로, 다양한 주파수대의 고유 진동수를 가지는 부품들의 진동을 감쇄시킬 수 있도록 그 진동수를 변화시킬 수 있는 다이나믹 댐퍼를 제공하는데 그 목적이 있다.The present invention has been made in view of the above, and an object thereof is to provide a dynamic damper capable of changing the frequency so as to attenuate the vibration of components having natural frequencies in various frequency bands.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시에를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

본 발명의 일 실시예에 따른 다이나믹 댐퍼가 도 2에 도시되어 있다.A dynamic damper according to one embodiment of the invention is shown in FIG. 2.

도시된 바와 같이, 본 발명의 일 실시예에 따른 다이나믹 댐퍼는 고정 브라켓(11)과 질량체(11)와 하나의 수직 탄성부 및 두 개의 수평 탄성부를 포함하고 있다.As shown, the dynamic damper according to the embodiment of the present invention includes a fixing bracket 11 and the mass 11, one vertical elastic portion and two horizontal elastic portions.

고정 브라켓은 평판 형상의 고정부(16)와 고정부(16)의 양측으로부터 상방으로 연장하는 한 쌍의 지지부(17)를 가지는 대략 U형상의 부재이다. 이 고정 브라켓은 볼트와 같은 체결구(18)에 의해 고정부(16)가 차체(19)에 체결됨으로써 차체(19)에 고정된다. 고정부(16)의 중앙에는 관통공(16a)이 형성되고, 지지부(17)에는 각각 서로 대향하는 세로 방향 안내공(17a)이 형성된다.The fixing bracket is a substantially U-shaped member having a flat plate-shaped fixing portion 16 and a pair of supporting portions 17 extending upward from both sides of the fixing portion 16. The fixing bracket is fixed to the vehicle body 19 by fastening the fixing portion 16 to the vehicle body 19 by a fastener 18 such as a bolt. The through hole 16a is formed in the center of the fixing part 16, and the longitudinal guide hole 17a which is mutually opposed to each other is formed in the support part 17, respectively.

질량체(11)는 고정 브라켓의 양 지지부(17) 사이에 위치되며, 진동이 발생되는 부품(미도시)에 직접 연결된다.The mass 11 is located between both supports 17 of the fixing bracket and is directly connected to a component (not shown) in which vibration is generated.

탄성부는 각각, 도 3에도 도시된 바와 같이, 볼트(12a, 12b)와 코일 스프링(13a, 13b)으로 이루어진다. 다수의 관통공(12c)이 볼트(12a, 12b)의 길이 방향을 따라 형성된다. 또한, 코일 스프링(13a, 13b)은 한쪽 부분이 볼트(12a, 12b)의 나사산을 따라 볼트(12a, 12b)에 감겨진다.As shown in Fig. 3, the elastic portion is composed of bolts 12a and 12b and coil springs 13a and 13b, respectively. A plurality of through holes 12c are formed along the longitudinal direction of the bolts 12a and 12b. In addition, one part of the coil springs 13a and 13b is wound around the bolts 12a and 12b along the threads of the bolts 12a and 12b.

이러한 탄성부는 고정 브라켓의 고정부(16) 및 지지부(17)에 각각 고정되고, 스프링(13a, 13b)의 다른쪽 단부는 질량체(11)에 연결된다. 이에 따라 질량체(11)는 3 개의 탄성부에 의해 지지된다.This elastic portion is fixed to the fixing portion 16 and the supporting portion 17 of the fixing bracket, respectively, and the other ends of the springs 13a and 13b are connected to the mass 11. Thereby, the mass body 11 is supported by three elastic parts.

좀더 상세하게 살펴보면, 볼트(12a, 12b)는 고정부의 관통공(16a) 및 지지부(17)의 안내공(17a)을 관통하고, 질량체(11)를 향해 연장한다. 고정 너트(14a, 14b)가 고정부(16) 및 지지부(17)의 내측면에 접촉되도록 볼트(12a,12b)에 체결된다. 고정 너트(14a, 14b)에는 볼트(12a, 12b)의 길이 방향과 직각인 방향으로 관통공이 형성된다. 이에 따라, 스냅 핀(15a, 15b)이 고정 너트(14a, 14b)의 관통공 및 볼트(12a, 12b)의 관통공(12c)들 중 어느 한 관통공을 관통하는 것에 의해 볼트(12a, 12b)는 고정부(16) 및 지지부(17)에 대해 고정된다. 여기서, 한 쌍의 지지부(17)에 고정된 탄성부의 스프링(13a, 13b)은 볼트(12a, 12b)의 외측에 위치된 부분의 길이가 동일하도록, 즉 탄성 계수가 동일하도록 설정된다.In more detail, the bolts 12a and 12b penetrate through the through hole 16a of the fixing portion and the guide hole 17a of the support portion 17 and extend toward the mass body 11. The fixing nuts 14a and 14b are fastened to the bolts 12a and 12b so as to contact the inner surfaces of the fixing portion 16 and the supporting portion 17. Through-holes are formed in the fixing nuts 14a and 14b in a direction perpendicular to the longitudinal direction of the bolts 12a and 12b. Accordingly, the snap pins 15a and 15b penetrate through the through holes of the fixing nuts 14a and 14b and any one of the through holes 12c of the bolts 12a and 12b. ) Is fixed relative to the fixing part 16 and the supporting part 17. Here, the springs 13a and 13b of the elastic portions fixed to the pair of support portions 17 are set such that the lengths of the portions located outside the bolts 12a and 12b are the same, that is, the elastic modulus is the same.

이러한 구성을 가지는 본 발명의 일 실시예에 따른 다이나믹 댐퍼는, 수직 탄성부의 스프링(13a) 길이가 변화되는 것에 의해, 댐퍼의 고유 진동수가 변화된다. 즉, 스냅핀(15a)을 수직 탄성부의 고정 너트(14a) 및 볼트(23a)의 관통공(12c)들로부터 분리한 다음 볼트(12a)를 상하 방향으로 이동시키고, 볼트(12a)의 다른 관통공(12c)과 고정 너트(14a)의 관통공을 맞추어 스냅핀(15a)을 고정 너트(14a)와 볼트(12a)의 관통공에 삽입한다. 이와 같이 볼트(12a)가 상하로 이동되면, 스프링(13a)의 권수가 변화되어 탄성 계수가 변화된다. 스프링(13a)의 탄성 계수가 변화되는 것에 의해 질량체(11)의 중량 및 스프링(13a, 13b)들의 탄성 계수로 결정되는 다이나믹 댐퍼의 고유 진동수도 변화된다.In the dynamic damper according to the embodiment of the present invention having such a configuration, the natural frequency of the damper is changed by changing the length of the spring 13a of the vertical elastic portion. That is, the snap pin 15a is separated from the fixing nut 14a of the vertical elastic portion and the through holes 12c of the bolt 23a, and then the bolt 12a is moved up and down, and the other penetration of the bolt 12a is carried out. The snap pin 15a is inserted into the through-hole of the fixing nut 14a and the bolt 12a by matching the through-hole of the hole 12c and the fixing nut 14a. When the bolt 12a is moved up and down in this manner, the number of turns of the spring 13a is changed to change the elastic modulus. By changing the elastic modulus of the spring 13a, the natural frequency of the dynamic damper determined by the weight of the mass 11 and the elastic modulus of the springs 13a and 13b also changes.

바람직하게는, 수직 탄성부의 볼트(12a)에 형성된 관통공(12c)들은 통상의 부품들의 각 고유 진동수에 대응될 수 있는 위치에 형성된다. 이에 따라, 진동이 발생되는 부품의 종류에 관계없이 각 부품들의 고유 진동수에 대응되도록 다이나믹 댐퍼의 진동수가 조정될 수 있다.Preferably, the through holes 12c formed in the bolt 12a of the vertical elastic portion are formed at positions that can correspond to respective natural frequencies of the conventional parts. Accordingly, the frequency of the dynamic damper may be adjusted to correspond to the natural frequency of each component regardless of the type of the component in which the vibration is generated.

이때, 수직 탄성부의 스프링 권수가 변화되면, 두 개의 수평 탄성부는 수평을 유지하면서 지지부(17)의 안내공(17a)을 따라 상하로 이동된다.At this time, when the spring number of the vertical elastic portion is changed, the two horizontal elastic portions are moved up and down along the guide hole 17a of the support 17 while maintaining the horizontal.

한편, 본 실시예에서는 고정 브라켓의 지지부와 수평 탄성체가 질량체의 양측에 설치된 것으로 도시 및 설명되었으나, 여기에 부가하여 지지부와 수평 탄성체가 질량체의 전후측에 설치될 수도 있다.On the other hand, in the present embodiment has been shown and described that the support portion and the horizontal elastic body of the fixing bracket is installed on both sides of the mass body, in addition to the support portion and the horizontal elastic body may be provided on the front and rear sides of the mass body.

싱기된 바와 같은 본 발명에 따르면, 수직 탄성부의 볼트가 상하로 이동되는 것에 의해 스프링의 탄성 계수가 변화되어 다이나믹 댐퍼의 진동수가 변화된다. 이에 따라 하나의 댐퍼로 다양한 주파수대의 고유 진동수를 가지는 부품들의 진동을 감쇄시킬 수 있다는 장점이 있다.According to the present invention as described above, the elastic modulus of the spring is changed by moving the bolt of the vertical elastic part up and down, thereby changing the frequency of the dynamic damper. Accordingly, there is an advantage in that a damper can attenuate vibrations of components having natural frequencies in various frequency bands.

이상에서는, 본 발명을 특정의 바람직한 실시예에 대해서 도시하고 설명하였다. 그러나, 본 발명은 상술한 실시예에만 한정되는 것은 아니며 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 이하의 특허청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어남이 없이 얼마든지 다양하게 변경실시할 수 있을 것이다.In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains can vary as many without departing from the spirit of the technical idea of the present invention described in the claims below. Modifications may be made.
