ABSTRACT:
A welded spoke wheel having a specially designed hub and knock-down crank shaft. The hub is a cylindrical tube with welded end caps. The crank shaft is assembled from a center shaft and two outer shafts. The outer shafts have radial tabs which engage axial slots formed in the center shaft. A flange is welded to each of the outer shafts to provide a surface for enabling the outer shafts to be secured to the hub end caps. This axially and rotationally locks the crank shaft to the hub.
