Abstract
A dual-wheel differential system includes an in inner hub, an outer hub, and a differential assembly mechanically coupled between the inner hub and the outer hub to allow the inner hub and the outer hub to rotate at different angular speeds. A user-actuatable locking system is configured to mechanically lock the inner hub to the outer hub. The user-actuatable locking system may include at least one axially-translating or radially-translating locking pin configured to engage at least one of the inner hub and the outer hub. The locking system may be pneumatically, hydraulically, or electromechanically actuated.
