이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예들을 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 감쇠장치가 구비된 다판 클러치가 채용된 변속장치의 일부가 도시된 구성도이고, 도 2는 도 1의 A부분의 측단면도이다.1 is a configuration diagram showing a portion of a transmission employing a multi-plate clutch with a damping device according to the present invention, Figure 2 is a side cross-sectional view of portion A of FIG.

도 1, 도 2에 도시된 바와 같이, 본 발명의 감쇠장치가 구비된 다판 클러치는 구동축(X-X')상에 클러치 하부(10)가 스플라인 결합되고, 클러치 중간부(20)가 상기 클러치 하부(10)에 외삽되어 스플라인 결합되며 외측에는 다판(20')이 형성된다.1 and 2, in the multi-plate clutch provided with the damping device of the present invention, the clutch lower portion 10 is splined on the drive shaft X-X ', and the clutch middle portion 20 is the clutch. Extrapolated to the lower part 10 and spline-coupled thereto, and a multi-plate 20 'is formed outside.

그리고, 상기 클러치 중간부(20)의 다판(20')과 상호 교번적으로 배치되도록 내측에 다판(30')이 형성되고 상기 클러치 중간부(20)의 외측에 위치되며 구동축(X-X')상을 따라 슬라이딩 가능하게 장착되어 인접 주축기어단(3,4)에 동력을 전달하는 클러치 상부(30)가 구비된다.In addition, the multi-plate 30 ′ is formed on the inner side so as to be alternately disposed with the multi-plate 20 ′ of the clutch middle portion 20, and is positioned outside the clutch middle portion 20, and the drive shaft X-X ′. Clutch upper portion 30 is slidably mounted along the upper side to transmit power to adjacent spindle gear stages 3 and 4.

상기 클러치 상부(30)의 외주면에는 변속시 좌우 슬라이딩 이동을 위해 시프트 포크부(미도시)와 연결되는 홈부(31)가 형성된다.The outer circumferential surface of the clutch upper portion 30 is formed with a groove portion 31 connected to the shift fork portion (not shown) for the left and right sliding movement at the time of shifting.

또한, 상기 클러치 하부(10)와 중간부(20) 사이에 감쇠수단(40)이 구비되어 변속시 발생되는 충격이나 엔진의 회전진동 등을 흡수한다.In addition, the damping means 40 is provided between the clutch lower portion 10 and the intermediate portion 20 to absorb the shock generated during the shift or rotational vibration of the engine.

상기 감쇠수단(40)은 상기 클러치 하부(10)와 중간부(20) 사이에 원주방향으로 일정한 간격을 두고 형성된 다수의 챔버(40')에 개재되어 탄성력을 제공하는 탄성부재로 이루어지는데, 상기 탄성부재는 토셔널 스프링(TORSIONAL SPRING)(41)으로 구성된다.The damping means 40 is made of an elastic member interposed in a plurality of chambers 40 'formed at regular intervals in the circumferential direction between the clutch lower portion 10 and the intermediate portion 20 to provide an elastic force. The elastic member is composed of a torsional spring (TORSIONAL SPRING) (41).

상기와 같이 구성되는 본 발명에 따른 감쇠장치가 구비된 다판 클러치의 작용을 설명하면 다음과 같다.Referring to the operation of the multi-plate clutch with a damping device according to the present invention configured as described above are as follows.

구동축(X-X')이 회전되어 클러치 하부(10)에 스플라이 결합된 클러치 중간부(20)가 회전되고, 변속시 시프트 포오크에 의해 상기 클러치 상부(30)를 좌우로 이동시키면 내측의 다판(30')과 상기 클러치 중간부(20)의 다판(20')이 상호 접촉되어 상기 클러치 상부(30)로 구동력이 전달된다.When the drive shaft (X-X ') is rotated and the clutch middle portion 20 spliced to the clutch lower portion 10 is rotated, and the clutch upper portion 30 is moved left and right by shift forks during shifting, the inner multi-plate 30 'and the multi-plate 20' of the clutch intermediate portion 20 are in contact with each other, and a driving force is transmitted to the clutch upper portion 30.

그리고 상기 클러치 상부(30)의 구동력은 인접한 주축기어(3, 4)에 전달되어 회전하게 한다.And the driving force of the clutch upper portion 30 is transmitted to the adjacent spindle gear (3, 4) to rotate.

이때 상기 클러치 하부(10)와 중간부(20) 사이에 개재된 토셔널 스프링(41)에 의해 변속시 단별 회전비가 다름에 따른 충격이나 엔진의 회전진동 등을 흡수하여 감쇠시킬 수 있게 된다.At this time, by the torsion spring 41 interposed between the clutch lower portion 10 and the intermediate portion 20, it is possible to absorb and attenuate shocks or rotational vibrations of the engine due to different rotational speed ratios when shifting.

이상과 같이 본 발명에 따른 감쇠장치가 구비된 다판 클러치를 예시된 도면을 참조로 설명하였으나, 본 명세서에 개시된 실시예와 도면에 의해 본 발명은 한정되지 않으며 그 발명의 기술사상 범위내에서 당업자에 의해 다양한 변형이 이루어질 수 있음은 물론이다.As described above, the multi-plate clutch provided with the damping device according to the present invention has been described with reference to the illustrated drawings. However, the present invention is not limited by the embodiments and drawings disclosed herein, and the skilled person within the technical scope of the present invention. Of course, various modifications can be made.

상기한 바와 같은 본 발명의 감쇠장치가 구비된 다판 클러치는 클러치 중간부와 하부 사이에 적정한 탄성력을 제공하는 토션널 스프링을 개재함으로써 변속시 각 단별 회전비의 다름에 따른 충격이나 엔진의 회전진동을 감쇠할 수 있는 장점이 있다.The multi-plate clutch provided with the damping device of the present invention as described above attenuates the shock or rotational vibration of the engine due to the difference in the rotation ratio of each stage during shifting by providing a torsional spring that provides an appropriate elastic force between the clutch middle portion and the lower portion. There is an advantage to this.

또한, 전단(1~5단, 후단)을 다판 클러치 뭉치 구조로 하면 기존의 변속기와 엔진의 동력을 전달하는 디스크 클러치 장치 어셈블리를 제거할 수 있는 장점이 있으며, 특히 자동 변속 조작 기어박스(Automatic SHIFTING GEARBOX)의 구현을 쉽게 할 수 있는 장점이 있다.In addition, the front (1-5 stage, rear end) of the multi-plate clutch bundle structure has the advantage of removing the disc clutch unit assembly that transmits the power of the existing transmission and the engine, in particular automatic shifting gearbox (Automatic SHIFTING) GEARBOX) is easy to implement.
