Abstract

A generator wheel hub includes a mandrel, a winding frame, two yoke discs, a plurality of yoke claws, a shell and a magnetic force unit. The winding frame is magnetically permeable and includes two side walls, a cylinder wall connected between the side walls, a winding slot between the side walls and the cylinder wall, and a coil wound on the The winding slot for the coil. Each of the yoke plates includes a plurality of radially extending protrusions, and a plurality of pole peg grooves formed between the protrusions, the yoke plates are respectively connected to the side walls and the magnets The pole peg slots of the yoke disc are staggered with each other. The yoke claws are respectively inserted in the pole bolt slots, and each includes an axial section extending to the outside of the winding slot. The magnetic force unit is arranged on the inner peripheral surface of the housing and has a plurality of magnets corresponding to the yoke claws.

Description

technical field

[0001] The invention relates to a wheel hub for bicycles, in particular to a generator hub. Background technique

[0002] U.S. Patent No. 7002880 and Chinese Taiwan Patent Application No. 92107400 and No. 94215996 disclose a generator hub, a bobbin used is used to provide a coil winding, and to provide the insertion of a plurality of yoke claws Positioning is used so that there are multiple slots distributed around the periphery of the bobbin. When manufacturing, the first disadvantage is that the groove-like structure around the bobbin is adjacent to the winding area, because it is easy to hook the thread. Therefore, it will hinder the winding work. The second disadvantage is that the winding frame is usually made of plastic material, which is easily deformed after winding and hinders the positioning of the yoke claws. The third disadvantage is that the slot on the winding frame determines the As for the number of poles of the power generation hub, since th...
