Abstract

A bicycle hub dynamo 1 comprises a hub spindle 5 adapted to be mounted to a frame of the bicycle; a hub body 6 disposed around the hub spindle 5, wherein the hub body 6 has a pair of axially spaced hub flanges 12a, 12b; a plurality of bearings 7, 8 disposed between the hub body 6 and the hub spindle 5 for rotatably supporting the hub body 6 relative to the hub spindle 5; and a generator 9 disposed between the hub body 6 and the hub spindle 5, wherein the generator generates electricity in response to rotation of the hub body 6 relative to the hub spindle 5. A freewheel 10 is disposed on a first side of the hub body 6, wherein the freewheel 10 is adapted to mount a plurality of sprockets 54.

Description

technical field [0001] The present invention relates to a hub dynamo, in particular to a hub dynamo for a bicycle arranged on the central part of a bicycle wheel. Background technique [0002] Generally, the hub disposed at the central portion of the bicycle wheel has a hub axle that is detachably and non-rotatably mounted on the bicycle fork (or frame), a hub body that is freely rotatably mounted on the hub axle, and A bearing that supports the hub body in a freely rotatable manner relative to the hub shaft. In addition, the hub body forms a pair of hub flanges to which spokes of the wheel can be fixed on outer peripheries of both ends thereof. [0003] In a bicycle hub having such a structure, a hub dynamo is known in which a power generating mechanism used as a power source for lighting or the like is incorporated in the hub body. Therefore, when the power generating mechanism is assembled inside the hub body, the power generation efficiency is improved and the turning ...
