Abstract
A locking mechanism for releasably locking a wheel to a rotatable hollow shaft having a terminal end includes expandable segments located axially outwardly of the shaft terminal end, and an expanding rod extending through the shaft and segments. Axial movement of the rod relative to the shaft and segments selectively expands the segments outwardly into releasable locking engagement with a sleeve positioned over the segments.
