Abstract
Systems and methods for an interaxle differential (IAD). In one example, the IAD comprises a locking assembly that includes a friction clutch, the friction clutch includes a clutch pack that comprises plurality of plates configured to engage and disengage to inhibit and permit speed differentiation between a first axle differential and a second axle differential. The IAD further includes a supply lubrication passage that comprises an inlet that receives a lubricant from an enclosure surrounding an input gear of an axle differential and a first outlet flowing the lubricant to a gear coupled to the clutch pack.

A method for lubricating an interaxle differential (IAD), comprising:
- flowing a lubricant through a supply lubrication passage that receives, at an inlet, splash lubricant from an input gear in a first axle differential;
- and
- flowing the lubricant through a first outlet of the supply lubrication passage to a gear coupled to a clutch pack;
- and
- flowing the lubricant through a second outlet of the supply lubrication passage to an input bearing coupled to a shaft that extends from an input interface.
