Abstract
The invention is an improved road wheel assembly for a tracked vehicle such s a tank. The improvement is a wear ring in the spiders of the road wheel for protecting the spiders from abrasion by center guides of the vehicle track. The spiders define annular pockets to retain the wear rings and the wear rings are comprised of a matrix material with ceramic particle distributed therein. The matrix material is tougher and more flexible than both the metal of which the spiders are made and the particles whereas the particles are harder and more abrasion resistant than the matrix material or the spiders.
