The invention relates to a disc hub assembly and a dual mass flywheel. The disc hub assembly comprises a disc hub (1) and an elastic component (3), the disc hub (1) is provided with an inner connecting part used for being connected with a shaft piece (2) in an anti-rotation mode on the radial inner side, and the elastic component (3) can be tensioned between the disc hub (1) and the shaft piece (2) in the axial direction when the disc hub (1) is connected with the shaft piece (2) in an anti-rotation mode, so that friction damping in the circumferential direction is formed between the disc hub (1) and the shaft piece (2). The dual-mass flywheel comprises the disc hub assembly. 本发明涉及一种盘毂组件和双质量飞轮。盘毂组件包括盘毂(1)和弹性构件(3)，其中，盘毂(1)其在径向内侧构造有用于与轴件(2)抗旋转连接的内连接部，弹性构件(3)能够在盘毂(1)与轴件(2)抗旋转连接时沿轴向张紧在盘毂(1)和轴件(2)之间，从而在盘毂(1)和轴件(2)之间形成在周向上的摩擦阻尼。双质量飞轮包括上述的盘毂组件。
