However, the wheel hub of this structure makes the structure of the whole vehicle more complicated and cumbersome, and the maintenance of the broken or damaged spokes is difficult for maintenance. In today's rapid development of the rim manufacturing materials, the stability of the structure of the wheel itself depends on the rim itself. The strength of the material is ensured, so a new type of wheel hub is designed for the above drawbacks.
