Track system

Abstract

The present disclosure relates to a sub-frame for rotationally supporting a primary wheel of a track system. The sub-frame comprises a sub-frame body, the sub-frame body defining a downwardly-facing surface to be supported by a frame of the track system, an upwardly-facing surface opposite the downwardly-facing surface, a cavity for rotationally receiving the primary wheel, and apertures extending from the upwardly-facing surface to the downwardly-facing surface for accepting fasteners for attachment of the sub-frame to the frame of the track system.

Dependencies are inferred from the claim text.
