ABSTRACT:
Disclosed is a shock absorbing wheel hub for attachment to the axle of a vehicle. The hub has a central flange portion and an annular rim. The rim has a pair of spaced mounting surfaces formed on the periphery thereof for attaching a pair of pneumatic tires with inclined road-engaging treads. A flange is formed on the rim between the mounting surfaces and extends radially outward between the tires. A cylindrical contact surface is formed on the exterior of the flange and carries a tread thereon. The central flange is provided with bores for attachment to the lug bolts of a vehicle axle. Circumferentially spaced resilient spokes extend radially from the central flange and are connected to the hub. A pair of inflation check valves are attached to the rim to communicate respectively with the interior of each pneumatic tire. A flow passage is provided in the rim interconnecting the pneumatic tires for allowing air flow therebetween. An interchangeable flow restricter is mounted in the rim for controlling the flow of air between the two tires. In another embodiment, the spokes have semispherical bearing surfaces formed thereon resiliently held in receptacles formed in the rim. In yet another embodiment, the road-engaging surfaces of the tires are curved from side to side.
