ABSTRACT:
Disclosed is a wheel having two staggered rows of surface-gripping, radially-yielding feet. When the wheel encounters an obstacle, a spring compresses, thereby permitting the feet to deflect and absorb shock that would have otherwise been imparted to the vehicle. Each foot has a longitudinally-extending slot having a rubber stop at one end thereof. A plate mounted on the wheel extends into the slot. As a foot springs outwardly, the plate slides in the slot until it contacts the rubber stop, thus preventing further radial movement of the foot. A set of rollers mounted forward and rearward of each foot ride in a corresponding set of slots on the adjacent foot surface to reduce wear.
