A bicycle rear wheel hub structure comprises a hub shell, a flywheel installed at one end of the hub shell and a hub mandrel fixed to the hub shell in a penetrating mode through a bearing, the flywheel is fixed to one end of the hub shell in a rotating mode through a driving body, and the driving body is fixed to the hub mandrel through a bearing sleeve. One end of the driving body and the hub shell are fixed through a bearing, the flywheel is fixed to the other end of the driving body in a rotating mode, a brake band-type brake is further installed between the flywheel and the hub shell, a brake box in the brake band-type brake is fixed to the driving body through a band-type brake bearing, and a brake disc in the brake band-type brake is fixed to the corresponding end of the hub shell in a sleeved mode. One end of the driving body is a step end, the band-type brake bearing can be conveniently fixed, the step end further extends to form a threaded end, the flywheel can be conveniently rotated and fixed, and the bicycle rear wheel hub structure is good in braking effect, more reasonable in layout and more compact in structure and has practical value.
一种自行车后轮花鼓结构,包括花鼓壳、安装于该花鼓壳一端的飞轮以及通过轴承穿固于该花鼓壳的花鼓芯轴,该花鼓壳一端通过一驱动体旋固该飞轮,该驱动体通过轴承套固于该花鼓芯轴,该驱动体一端与该花鼓壳通过轴承固定而另一端旋固该飞轮,位于该飞轮和花鼓壳之间还安装一刹车抱闸,该刹车抱闸中的刹车闸盒通过抱闸轴承固定于该驱动体,而该刹车抱闸中的刹车闸盘套固于该花鼓壳对应端,该驱动体一端呈台阶端,便于该抱闸轴承固定,该台阶端还延伸螺纹端,便于该飞轮旋转固定,本发明提供一种自行车后轮花鼓结构,制动效果好,布局更合理,结构更紧凑,具有实用价值。
