Abstract
An axle assembly that includes a spindle and an axle shaft. The spindle includes a spindle hole that extends along an axis and a spindle journal that protrudes toward the axis.

The spindle journal cooperates with an axle shaft journal or a seal to restrict lubricant from flowing between the axle shaft and the spindle.
Claims16
An axle assembly comprising:
- a spindle, the spindle comprising a spindle hole that extends along an axis and a spindle journal that protrudes toward the axis;
- and
- an axle shaft that is disposed in the spindle hole and is rotatable about the axis, the axle shaft further comprising an axle shaft journal that protrudes away from the axis and toward the spindle journal, wherein the axle shaft journal and the spindle journal cooperate to restrict lubricant from flowing between the axle shaft and the spindle.
An axle assembly comprising:
- a spindle, the spindle comprising an inner side that extends from a free end of the spindle and that at least partially defines a spindle hole that extends along an axis, wherein the inner side includes an inner side surface that is disposed closer to the axis than a remainder of the inner side;
- and
- an axle shaft that is disposed in the spindle hole and is rotatable about the axis, the axle shaft further comprising an axle shaft journal that protrudes away from the axis and toward the inner side surface, wherein the inner side surface and the axle shaft journal cooperate to restrict lubricant from flowing between the axle shaft and the spindle.
