Abstract
Apparatus for the interface of an elevated vertical roadway and vehicle wheel, for achieving greater traction than possible using vehicle weight, and for minimizing vehicle wheel oscillation against the roadway, for minimizing roadway damage associated with heavy vehicle motion, said apparatus having a roadway/wheel interface geometry comprising a substantially vertical roadway with substantially vertical but concave sides, and convex wheel rims rolling on said convex roadway sides, with wheel rim width which is equal to or less than the width of the concave part of the roadway side; and said apparatus having a compression apparatus, independent of vehicle weight, for causing the wheels to be in substantial compression against the side of the roadway, in one said embodiment said compression apparatus being formed by the combination of pairs of parallel wheel axles on opposite sides of the roadway, and cables wound in substantial tension around each said pair of axles, said tensioned cables urging said axles toward one another and thus compressing the wheels strongly against the sides of the roadway.
