The difference between the internal and external axles of the American axle in structure

First, let's take a look at the two important products on the amercian axle, namelythe wheel hub and the brake drum.

The brake drum is outside and the wheel hub is inside, which is an amercian external axle.

The brake drum is inside and the wheel hub is outside, which is an amercian internal axle.

External axles usually refer to the axle structure in which certain key components (such as brake system, suspension system, etc.) are designed on the outside of the axle or in an easily accessible position. This design facilitates maintenance and repair because customers or maintenance personnel can more easily access these components for replacement or adjustment.

Internal axles refer to key components designed inside the axle or in a more concealed position. This design may increase the difficulty of maintenance to a certain extent because more parts need to be disassembled to access the internal mechanical structure.
