Abstract
An axle assembly of a driving wheel of the present invention removes a hub and forms a brake disc integral type hub in order to integrate the hub and a brake disc. A protrusion portion is formed on an end of the brake disc integral type hub, and one portion of the protrusion portion is provided to be opposite to an inner race of a bearing, and a lower portion of the protrusion portion is provided to be opposite to a bearing inner race shaft. Since constructed such above, its structure is simple and its weight reduces. Also, since an assembly process is simple, and an assembly operation time becomes shortened, cost may be saved.
