Abstract
A track apparatus is provided for mounting on a rotatable axle of a vehicle. The track apparatus includes a flexible track having an upper length and a ground-engaging lower length. A drive wheel is mountable to the rotatable axle so as to drive the flexible track in response to rotation of the axle. Leading and trailing idler assemblies are attached to the frame. Each idler assembly includes a non-pneumatic idler wheel having a plurality of voids therein. In addition, a bogie assembly is also supported by the frame. The bogie assembly includes a non-pneumatic bogie wheel having a plurality of voids therein. The idler wheels and the bogie wheels have increased dimensional reliability and provide shock absorption and self-cleaning features to the track apparatus.
