Axle spindle and method for making the same

摘要

A spindle for an axle is capable of supporting a vehicle wheel which is rotatably mounted thereon at a pair of axially disposed bearings. The spindle includes a cylindrical portion at its outer end which serves as an outer bearing mounting region while the portion of the spindle inwardly of the outer bearing mounting region is provided a frusto-conical outer surface. The inner wheel bearing has an inner race with a frusto-conical inner surface so that the frusto-conical outer surface of the spindle will serve as the inner bearing mounting region. Such a spindle is preferably cold formed from a hollow tubular blank having a generally uniform external diameter and wall thickness.
