Independently rotating wheels with planetary drive

摘要

A wheel end assembly having a dual wheel configuration includes independently rotating wheel hubs to reduce tire wear. The wheel end includes a first planetary gear assembly with a sun gear driven by a differential side gear and a ring gear for driving one wheel hub. A second planetary gear assembly with a sun gear driven by a differential side gear and a ring gear drives another wheel hub. A differential assembly is coupled to the first and second sun gears to allow the first and second wheel hubs to rotate relative to one another as the vehicle executes turning maneuvers.
