Embodiment Construction

[0008] With reference to accompanying drawing of the present invention, the structure of a kind of electric bicycle wheel of the present invention, it comprises wheel spoke (1), wheel hub (2), and described wheel hub (2) is in the central part of wheel spoke, and wheel spoke (1) and wheel hub ( 2) make an integral structure between them, and install an insert (3) on the central axis of the hub (2) of the wheel. The end of the insert (3) has a flange (4), The two ends of the central hole at both ends of the insert (3) are provided with bearing holes (5) for installing bearings, and the insert (3) is installed and fixed with the hub (2) by bolts (6) through the flange (4) at its end together.

Abstract

Disclosed is a structure of an electric bicycle wheel. A bushing is fixedly installed on middle axis portion of a wheel hub of a wheel. A flange is arranged on the end portion of the bushing. The two ends of a central hole of the two ends of the bushing are provided with bearing holes. Bearings are installed in the bearing holes. The bushing is fixedly installed together with the wheel hub through the flange on the end portion of the bushing by bolts. Due to the fact that the bushing is fixedly installed on the middle portion of the wheel hub of the wheel, and the two ends of the bushing are provided with bearing holes, the bearings are not directly installed on the wheel hub, once a installation portion of the bearings is damaged, only the bushing need replacing, and the entire wheel is enabled to return to service afresh. The structure of the electric bicycle wheel is capable of overcoming defects of existing electric bicycle wheel hub that the wheel hub on which the bearings are installed is easy to damage, and the wheel is easily caused to be scrapped.

Description

technical field [0001] The invention relates to a structure of a wheel, in particular to a structure of an electric bicycle wheel, and belongs to the technical field of electric bicycles. Background technique [0002] At present, the aluminum alloy wheel hub of an electric vehicle must be installed with bearings at the junction of the axle and the two ends of the hub at the junction of the axle and the hub, that is: the axle is directly fixed to the two ends of the hub through the bearings. However, the bearing is damaged. When the bearing is replaced, the bearing installation part of the aluminum alloy wheel hub is often damaged. In severe cases, the entire aluminum rim may even be unusable. For this, at present, there is no ideal solution. Contents of the invention [0003] The purpose of the present invention is to provide a structure for electric bicycle wheels, which overcomes the disadvantages of existing electric bicycle wheel hubs that the wheel hubs on which the b...
