Vibration absorber and automobile

The invention provides a vibration absorber and an automobile. The vibration absorber comprises a flange plate, connecting rubber and an inertia disc which are sequentially connected in a nested mode from inside to outside. The flange plate is connected with the inertia disc through the connecting rubber, a cavity extending in the circumferential direction is formed, and the cavity is provided with an inner side wall and an outer side wall which is farther from the flange plate than the inner side wall; the inner side wall is sleeved with a mass ring, the outer side wall is provided with a rubber protrusion protruding towards the mass ring, and the diameter of the mass ring can be changed. The vibration absorber can adapt to torsion modes of different gears, and vibration noise of an automobile transmission system can be reduced. 本发明提供了一种吸振器及汽车，本发明的吸振器包括由内至外依次嵌套相连的法兰盘、连接橡胶和惯量盘；所述连接橡胶使所述法兰盘与所述惯量盘连接，并且形成有沿周向延伸的腔体，所述腔体具有内侧壁和比所述内侧壁远离所述法兰盘的外侧壁；所述内侧壁上套设有质量环，所述外侧壁上设有向所述质量环凸出的橡胶凸起，所述质量环的直径能够发生变化。本发明的吸振器能够适应不同档位的扭转模态，
