구체적으로 다단으로 배치되는 제1 및 제2 댐퍼부(110,120)를 연결 및 설치 시에, 제1 댐퍼부(110)는 제2 댐퍼부(120)의 부품의 일부를 이용하여 설치될 수 있다. 즉 제1 댐퍼부(110)는 제2 댐퍼부(120)에 구비된 장착플레이트부(121)의 타측에 장착될 수 있다. 예를 들어 제2 댐퍼부(120)를 설치 공간에 설치하고, 제2 댐퍼부(120)의 부품인 장착플레이트부(121)를 이용하여 제1 댐퍼부(110)를 설치할 수 있다. 이에 의해 제1 댐퍼부(110)를 설치함과 동시에, 제1 댐퍼부(110)와 제2 댐퍼부(120)를 연결할 수 있다. Specifically, when connecting and installing the first and second damper parts 110 and 120 arranged in multiple stages, the first damper part 110 may be installed using a part of the components of the second damper part 120 . That is, the first damper part 110 may be mounted on the other side of the mounting plate part 121 provided in the second damper part 120 . For example, the second damper part 120 may be installed in an installation space, and the first damper part 110 may be installed using the mounting plate part 121 which is a component of the second damper part 120 . Accordingly, the first damper unit 110 may be installed and the first damper unit 110 and the second damper unit 120 may be connected.

이에 따라 본 발명은 제1 댐퍼부(110)를 설치하기 위한 부품의 일부를 생략할 수 있어서, 부품수가 축소되는 효과를 제공할 수 있다. 또한 조립공정이 단순해지고 원가가 절감되는 이점이 있다. Accordingly, the present invention can omit a part of the parts for installing the first damper part 110, thereby providing an effect of reducing the number of parts. In addition, there is an advantage in that the assembly process is simplified and the cost is reduced.

도 2를 참조하면 제1 댐퍼부(110)는 플라이휠부재(111)와, 제1 댐퍼스프링(112)을 포함할 수 있다. Referring to FIG. 2 , the first damper unit 110 may include a flywheel member 111 and a first damper spring 112 .

플라이휠부재(111)는 엔진부(10)의 출력축(11)에 결합되고 장착플레이트부(121)에 상대 회전하게 구비될 수 있다. 예를 들어 플라이휠부재(111)는 체결부재에 의해 엔진부(10)의 출력축(11)에 결합될 수 있다. 또한 플라이휠부재(111)는 일부가 절곡되게 형성됨으로써 제1 댐퍼스프링(112)을 지지할 수 있게 구비될 수 있다. The flywheel member 111 may be coupled to the output shaft 11 of the engine unit 10 and provided to rotate relative to the mounting plate unit 121 . For example, the flywheel member 111 may be coupled to the output shaft 11 of the engine unit 10 by a fastening member. In addition, the flywheel member 111 may be provided to support the first damper spring 112 by being partially bent.

제1 댐퍼스프링(112)은 플라이휠부재(111)와 장착플레이트부(121)의 사이에 설치되고, 장착플레이트부(121)의 원주 방향으로 복수 개가 이격되게 배치되어 탄성력을 제공할 수 있다. The first damper spring 112 may be installed between the flywheel member 111 and the mounting plate part 121 , and a plurality of first damper springs 112 may be disposed to be spaced apart in the circumferential direction of the mounting plate part 121 to provide elastic force.

여기서 장착플레이트부(121)는 제1 댐퍼스프링(112)의 반력에 의해 회전하게 구비될 수 있다. 구체적으로 장착플레이트부(121)는 제1 댐퍼부(110)의 드라이프플레이트 역할을 대체할 수 있다. 이에 따라 제1 댐퍼부(110)의 장착플레이트부(121)와 드라이브플레이트를 생략함으로써 부품수가 축소될 수 있다. Here, the mounting plate part 121 may be provided to rotate by the reaction force of the first damper spring 112 . Specifically, the mounting plate part 121 may replace the role of the drive plate of the first damper part 110 . Accordingly, the number of parts may be reduced by omitting the mounting plate part 121 and the drive plate of the first damper part 110 .

상기 제2 댐퍼부(120)는 제2 댐퍼스프링(125)과, 드라이브 플레이트(126)를 포함할 수 있다. The second damper part 120 may include a second damper spring 125 and a drive plate 126 .

The second damper spring 125 is installed on one side of the mounting plate part 121 and a plurality of the second damper springs 125 are disposed in the circumferential direction of the mounting plate part 121 to provide elastic force. For example, the mounting plate part 121 may serve as a retaining plate for stably installing the second damper spring 125 .

드라이브 플레이트(126)는 전달축부에 진간접적으로 결합되고, 제2 댐퍼스프링(125)의 반력에 의해 회전할 수 있다. The drive plate 126 is indirectly coupled to the transmission shaft portion, and may be rotated by the reaction force of the second damper spring 125 .

예를 들어 전달축부에는 스플라인 허브가 관통될 수 있고, 드라이브 플레이트(126)는 스플라인 허브의 원주면을 외부에서 감싸는 형태로 결합될 수 있다. 또한 드라이브 플레이트(126)는 가장자리를 따라 복수의 장착홈이 형성될 수 있고, 제2 댐퍼스프링(125)은 이러한 장착홈에 삽입될 수 있다. 이러한 구조에 의해 드라이브 플레이트(126)는 제2 댐퍼스프링(125)의 반력에 의해 회전할 수 있다. For example, a spline hub may pass through the transmission shaft portion, and the drive plate 126 may be coupled to a circumferential surface of the spline hub from the outside. In addition, a plurality of mounting grooves may be formed along the edge of the drive plate 126 , and the second damper spring 125 may be inserted into these mounting grooves. With this structure, the drive plate 126 may be rotated by the reaction force of the second damper spring 125 .

더욱 구체적으로 장착플레이트부(121)는 제1 장착플레이트(122)와 제2 장착플레이트(123)를 포함할 수 있다. More specifically, the mounting plate part 121 may include a first mounting plate 122 and a second mounting plate 123 .

The first mounting plate 122 may be provided to accommodate a surface of the second damper spring 125 facing the first damper part 110 . The second mounting plate 123 is provided to accommodate a surface of the second damper spring 125 in a direction opposite to the direction toward the first damper part 110 , and may be coupled to the first mounting plate 122 .

For example, the first damper spring 112 may be installed between the other ends of the first mounting plate 122 and the second mounting plate 123 and the flywheel member 111 .

예를 들어 제1 장착플레이트(122)는 타측 단부에 플라이휠부재(111)를 향하는 방향으로 절곡되어 형성된 제1 절곡부(122a)를 포함할 수 있다. 즉 제1 장착플레이트(122)는 전달축부의 반경 방향의 단부가 플라이휠부재(111)를 향하는 방향으로 절곡될 수 있다. For example, the first mounting plate 122 may include a first bent portion 122a formed by being bent in a direction toward the flywheel member 111 at the other end thereof. That is, the first mounting plate 122 may be bent in a direction toward the end of the transmission shaft in the radial direction toward the flywheel member (111).

또한 제2 장착플레이트(123)는 타측 단부에 플라이휠부재(111)를 향하는 방향으로 절곡되어 형성된 제2 절곡부(123a)를 포함할 수 있다. 즉 제2 장착플레이트(123)는 전달축부의 반경 방향의 단부가 플라이휠부재(111)를 향하는 방향으로 절곡될 수 있다. Also, the second mounting plate 123 may include a second bent portion 123a formed by being bent in a direction toward the flywheel member 111 at the other end thereof. That is, the second mounting plate 123 may be bent in a direction toward the end of the transmission shaft in the radial direction toward the flywheel member (111).
