1. An axle assembly comprising:
an input shaft that is rotatable about an axis;
an output shaft that is rotatable about the axis; and
an interaxle differential unit that includes:
a first side gear that is rotatable about the axis and is selectively couplable to the input shaft;
a second side gear that is rotatable about the axis with the output shaft;
a case that extends from the input shaft and that is rotatable about the axis with the input shaft, wherein the case includes an inner ring that engages the input shaft, an outer ring that is spaced apart from the inner ring, and a rib that extends from the inner ring to the outer ring;
a pinion pin that extends from the case and that is spaced apart from the input shaft; and
a pinion gear that is rotatably disposed on the pinion pin and that meshes with the first side gear and the second side gear.
