Axle housing assembly

摘要

An axle housing assembly includes a cast iron tube (46) having a pocket (70) that is formed proximate a first end (48) of the cast iron tube. The pocket is disposed generally transverse to a longitudinal axis of the cast iron tube. The axle housing assembly also includes an insert (72) made of steel connected to the pocket. The steel insert permits the cast iron tube (46) to be coupled to a cast iron carrier housing (30) by welding steel plugs (68) positioned in the carrier housing to the steel inserts.
