ABSTRACT:
The present invention discloses a high strength, shock absorbing wheel generally comprising a two piece hub, preferably of molded construction, a unitary solid wheel molded onto the hub of the wheel, and axle shaft bearings pressed into a central aperture provided in the hub of the wheel. The hub of the wheel comprises two identical halves, divided along a plane of separation perpendicular to the longitudinal axis of the axle upon which the wheel will rotate, with each hub section including a plurality of apertures disposed about its outer rim to form a plurality of passageways through the outer rim of the assembled hub sections, and further including a plurality of concentric grooves disposed about its outer edge and face to form a plurality of keyways therein. During molding of the tire onto the assembled hub of the wheel, tire material flows through each such passageway and into each such groove to form positive interlocks between hub and tire and to provide a system for absorbing and distributing impact shock through the structure of the wheel.
