A prop shaft assembly according to the present invention includes: a tube type member; a first and a second end connection part coupled to both side ends of the tube type member; and a damper which is accommodated in the tube type member and is located between the first and the second end connection part. The tube type member has a wall member confining an inner circumferential surface. The damper has a first damping device, a second damping device and a third damping device. The first damping device includes a first core and a first damping member fixed to the first core. The first damping member is spirally extended around the first core, and is combined to the inner circumferential surface. The second damping device is formed with a foam, and is located in the tube type member between the first and the third damping device. The second damping device is combined to the inner circumferential surface. The third damping device includes a second core and a second damping member fixed to the second core. The second damping member is extended spirally around the second core, and is combined to the inner circumferential surface. The prop shaft assembly is damped more effectively to control shell mode vibration.

    본 발명에 따른 프로프샤프트 조립체는 튜브형 부재, 튜브형 부재의 양쪽 단부에 커플링되는 제1 및 제2 단부 연결부 그리고 튜브형 부재 내에 수용되고 제1 및 제2 단부 연결부 사이에 위치되는 댐퍼를 포함한다. 튜브형 부재는 내부 원주 표면을 한정하는 벽 부재를 갖는다. 댐퍼는 제1 댐핑 장치, 제2 댐핑 장치 및 제3 댐핑 장치를 갖는다. 제1 댐핑 장치는 제1 코어 그리고 제1 코어에 고정되는 제1 댐핑 부재를 포함한다. 제1 댐핑 부재는 제1 코어 주위에서 나선형으로 연장되고, 내부 원주 표면과 결합된다. 제2 댐핑 장치는 폼으로 형성되고, 제1 및 제3 댐핑 장치 사이에서 튜브형 부재 내에 위치된다. 제2 댐핑 장치는 내부 원주 표면과 결합된다. 제3 댐핑 장치는 제2 코어 그리고 제2 코어에 고정되는 제2 댐핑 부재를 포함한다. 제2 댐핑 부재는 제2 코어 주위에서 나선형으로 연장되고, 내부 원주 표면과 결합된다.
