차량용 트윈 매스 플라이휠(10)이 다수의 회전연결구(40)에 의하여 연결된 두개의 동축상 배열인 상대회전 플라이휠 동체(11,17)로 구성된다. 각 연결구(40)는 일측 플라이휠 동체(12)에 회전 가능하게 연결된 제1링크(41)와 타측 플라이휠 동체(11)에 회전 가능하게 연결된 제2링크(42), 그리고 방사상 외측으로 운동하는 피봇트(45)로 구성된다. 상대회전에 대한 저항이 상대회전 각도에 따라 변화하는 가변 히스테리시스 마찰완화수단(50)이 플라이휠 동체 사이에서 작용한다. 이 완화수단(50)은 상이한 회전단계에서 작동하는 두 마찰완화판(151,155)로 구성될 수 있다. 상대회전이 탄성정지구(113)에 의하여 제한된다.

Date Aug. 20, 1992A twin mass flywheel for a vehicle comprising two co-axially arranged relatively rotatable masses interconnected by a plurality of pivotal linkages. Each linkage comprises a first link pivotally connected to one flywheel mass, a second link pivotally connected to the other flywheel mass and a common pivot joining the links to move radially outwardly. A resilient torque member in each common pivot operable after a predetermined rotation between the flywheel masses to resist said relative rotation. A variable hysteresis friction damping means, whose resistance to relative rotation changes as the relative angle of rotation is altered, acts between the flywheel masses. The damping means can be provided by two friction damping plates which operate at different stages of rotation. The relative rotation may be limited by resilient stops.
