Abstract
Abstract A resilient vehicle wheel, particularly for off-the-road vehicles, comprises a generally cylindrical tread wall of resilient material having circumferentially-spaced corrugations, an inner hub section, and a pair of inwardly-dished end walls of resilient material joining respective ends of the tread wall with the hub section. The end walls have angularly-spaced corrugations joining the corrugations of the tread wall and extending inwardly toward the hub section. Preferably the ridges of the end wall corrugations join the valleys of the tread wall corrugations, and vice versa, and the end wall valleys extend to a radius equal to, and advantageously greater than, the radius of the innermost portions of the tread wall valleys at respective ends of the wheel. The valleys of the end wall corrugations advantageously have respective series of alternate deeper and shallower portions spaced therealong, e.g., depressions. The resilient end walls and tread wall provide at least a major portion of the support for a load, and desirably the interior of the wheel is at atmospheric pressure.
