Description
본 고안은 비틀림 진동을 제진하여 추진축의 소음 및 안정성을 유지하는 추진축의 토션댐퍼 장착구조에 관한 것이다.The present invention relates to a torsion damper mounting structure of the propulsion shaft to suppress the torsional vibration to maintain the noise and stability of the propulsion shaft.
일반적으로 추진축은 변속기로 부터 최종 감속기어까지 동력을 전달하는 축으로서, 변속기는 엔진과 함께 프레임에 고정되어 있고 뒤차축은 스프링에 의해 프레임에 설치되어 있으므로 변속기와 뒤차축은 높이가 일정하지 않고 그 거리도 변동한다.In general, the propulsion shaft transmits power from the transmission to the final reduction gear. The transmission is fixed to the frame together with the engine, and the rear axle is installed on the frame by a spring. The distance also fluctuates.
따라서, 도 1에 나타낸 바와 같이 추진축(10)의 양단에 튜브(20)에 싸여진 유니버셜 조인트요크가 용접되고, 유니버셜 조인트요크에는 튜브(20)로 돌설되어 변속기의 주축 후부에 설치된 스플라인에 결합하여 전후로 접동할 수 있도록 한 슬리브요크(30)를 연결하여 추진축(10)의 각도 변화와 길이 변화에 대응하도록 하고, 추진축(10)의 소정 위치에는 변동하는 엔진의 토크를 받으면서 고속회전에 의한 비틀림 진동을 억제하는 토션댐퍼를 장착하여 구성한다.Accordingly, as shown in FIG. 1, the universal joint yoke wrapped in the tube 20 is welded to both ends of the propulsion shaft 10, and the universal joint yoke is protruded into the tube 20 and coupled to a spline provided at the rear of the main shaft of the transmission. By connecting the sleeve yoke 30 to be slidable to correspond to the change of the angle and the length of the propulsion shaft 10, and to the predetermined position of the propulsion shaft 10 is subjected to torsional vibration due to the high-speed rotation while receiving the torque of the engine changes The torsion damper that suppresses is installed.
상기 토션댐퍼는 분할된 추진축(10)의 분할면에 밴드(50)에 의해 결착된 댐퍼고무(40)을 두룬 구성으로, 추진축(10)의 회전 방향에 대한 정 또는 부의 가속도에 의한 비틀림 진동의 발생시 댐퍼고무(40)가 변형을 반복하여 그 내부마찰에 의해 비틀림 진동 에너지를 열로 바꾸어서 흡수하여 제진 작용을 한다.The torsion damper is composed of a damper rubber 40 bound by the band 50 on the divided surface of the divided propulsion shaft 10, the torsional vibration of the positive or negative acceleration relative to the rotation direction of the propulsion shaft 10 During generation, the damper rubber 40 repeatedly deforms and converts the torsional vibration energy into heat by its internal friction to absorb and dampen.
그러나 상기한 종래의 추진축(10)은 밴드(50)의 결착력에 의해 고착됨으로써, 반복된 변형을 이루는 과정에서 밴드(50)의 결착력이 떨어져 이완되어 성능이 저하되는 문제점이 있었다.However, since the conventional propulsion shaft 10 is fixed by the binding force of the band 50, the binding force of the band 50 is loosened in the process of forming the repeated deformation, and thus, the performance is reduced.
본 고안은 상기한 문제점을 해결하기 위하여 안출한 것으로서, 본 고안의 목적은 지속적으로 변형을 이루는 피로응력에도 성능 저하가 방지되는 추진축의 토션댐퍼 고정구조를 제공하는 데 있다.The present invention is devised to solve the above problems, an object of the present invention is to provide a torsion damper fixing structure of the propulsion shaft to prevent the performance degradation even in the fatigue stress continuously forming.

도 2는 본 고안에 의한 토션댐퍼를 적용한 추진축의 구성을 나타낸 요부 단면도.Figure 2 is a sectional view showing the main portion of the propulsion shaft to which the torsion damper according to the present invention is applied.

상기 목적을 실현하기 위한 본 고안의 실시예를 첨부한 도면 도 2를 참조하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings an embodiment of the present invention for realizing the above object is as follows.
도면에서 본 고안에 의한 추진축(10)의 토션댐퍼는 분할된 추진축(10)의 대향면에 각각 요부(12)를 형성하고, 상기 일측의 요부(12)에는 일측 외경을 둘러 고무부시(100)가 끼워진 연결부재(200)를 고무부시(100)를 수용하여 억지끼워 맞춤하며, 타측의 요부(12)에는 연결부재(200)를 형합수단에 의해 체결하여 구성한다.The torsion damper of the propulsion shaft 10 according to the present invention is formed in each of the recessed portion 12 on the opposing surface of the divided propulsion shaft 10, the one side recessed portion 12 around the outer diameter of the rubber bush 100 The fitting member 200 is fitted to the rubber bushing 100 to fit the fit, and the other side 12 is configured by fastening the connecting member 200 by the fitting means.
상기 형합수단은 타측의 요부(12) 내면과 이와 대향하는 연결부재(200)의 외면중 어느 일면에는 체결홈(220)을 형성하고, 다른 면에는 체결홈(220)에 끼워지는 체결돌기(14)를 형성하여 구성한다.The joining means forms a fastening groove 220 on one surface of the inner surface of the recessed part 12 on the other side and an outer surface of the connecting member 200 opposite thereto, and a fastening protrusion 14 fitted on the fastening groove 220 on the other surface. ) To form.
따라서 고무부시(100)가 내장된 상태에서 연결부재(200)에 의해 횡 방향의 압력을 받게되어 고무부시(100)의 결착력이 보장되고 고무부시(100)의 내부 마찰면이 확충됨으로써 에너지의 추진축(10)의 회전 방향에 대한 정 또는 부의 가속도에 의한 비틀림 진동의 발생시 고무부시(100)가 변형을 반복하면서 제진 작용을 하여도 분리 또는 느슨함이 해소되며, 고무부시(100)의 내부 마찰면이 확충됨으로써 성능 향상은 물론 장시간 사용시에도 성능이 유지되는 효과가 있다.Therefore, the pressure of the rubber bush 100 is secured by the connecting member 200 in the state in which the rubber bush 100 is embedded, so that the binding force of the rubber bush 100 is secured, and the inner friction surface of the rubber bush 100 is expanded, thereby promoting energy. When the torsional vibration due to the positive or negative acceleration with respect to the rotation direction of (10) occurs, even if the rubber bushing 100 performs a vibration damping action while repeating the deformation, the separation or loosening is eliminated, and the internal friction surface of the rubber bushing 100 is As a result of the expansion, the performance is improved and the performance is maintained even when used for a long time.
이상에서 설명한 바와 같이 본 고안은 지속적으로 변형을 이루는 피로응력에도 성능 저하가 방지되는 효과가 있다.As described above, the present invention has an effect of preventing performance deterioration even on fatigue stress continuously forming.
