The invention relates to a shock absorbing device for a bicycle wheel and belongs to the field of shock absorption of bicycles. The shock absorbing device comprises a separated outer wheel hub, a plurality of flexible spokes and a free hub. The separated outer wheel hub and the free hub are connected by the flexible spokes, and 6-12 flexible spokes are arranged. The free hub is of a circular ringstructure and is mounted on a rotating shaft of the wheel through a bearing. A plurality of grooves are formed in the circumferential direction on a peripheral surface as first matching holes connected to one ends of the flexible spokes. The flexible spokes are of arc-shaped structures in shape and the radial sections are elliptical. The separated outer wheel hub is of the circular ring structureformed by splicing a plurality of wheel hub segments, and each wheel hub segment is mounted corresponding to one flexible spoke. By adopting the separated wheel hub and the flexible spokes, the wheelhub and the spokes in contact with the ground are responsible for shock absorption of the wheel hub independently and other wheel hubs and spokes are not involved. Therefore, in the shock absorbing process, the bearing of the wheel does not shift relative to the top end of a front fork, so that an accident that the wheel collides with the top end of the front fork is avoided.
本发明一种自行车轮毂减震装置,属于自行车减震领域;包括分离式外轮毂、柔性辐条和花鼓;通过多个沿周向均布的柔性辐条连接所述分离式外轮毂和花鼓,柔性辐条的数量为6‑12个;所述花鼓为圆环结构,通过轴承安装于车轮转轴上,其外周面上沿周向开有多个凹槽,作为与所述柔性辐条一端连接的第一配合孔;所述柔性辐条外形为圆弧结构,径向截面为椭圆形;所述分离式外轮毂是由多个轮毂段拼接而成的圆环结构,每个轮毂段与一个柔性辐条对应安装,采用分离式的轮毂以及柔性辐条,与地面接触的轮毂及辐条单独负责车轮的减震,不涉及其他轮毂及辐条。因此在减震过程中,车轮的轴承相对前叉顶端不发生相对位移,因此不会发生车轮碰撞到前叉顶端的事故。
