APPARATUS TO REDUCE VIBRATION
본 발명의 실시예에 따른 진동 저감 장치는, 레일의 복부 부분을 사이에 두고 양측에 배치되되 적어도 일부분은 상기 복부 부분에 접하고 적어도 일부분은 상기 복부 부분과 연결된 하부 부분에 접하는 한 쌍의 댐퍼본체와, 상기 한 쌍의 댐퍼본체의 각각에 형성된 적어도 2개의 관통홀에서 상기 복부 부분 또는 상기 하단 부분에 대하여 이동 가능하게 구비되는 복수 개의 비탄성 충돌구와, 상기 한 쌍의 댐퍼본체를 각각 외부에서 감쌈으로써 상기 댐퍼본체가 외부로 노출되는 것을 방지시키는 한 쌍의 하우징을 포함할 수 있다.
The present invention relates to a vibration reduction device, and more particularly, to a vibration reduction device capable of reducing rolling noise by reducing vibration in a low-frequency region as well as vibration in a high-frequency region. A vibration reduction device according to an exemplary embodiment of the present invention includes: a pair of damper main bodies disposed at both sides with a web portion of a rail interposed therebetween, such that at least a part of the damper main body is in contact with the web portion and at least another part of the damper main body is in contact with a lower end portion of the rail which is connected to the web portion; a plurality of inelastic collision balls provided in at least two through holes formed in each of the pair of damper main bodies so as to be movable with respect to the web portion or the lower end portion; and a pair of housings configured to surround the pair of damper main bodies from the outside in order to prevent the damper main bodies from being exposed to the outside.
