Abstract
An arrangement for measuring the rolling resistance of tires. The arrangement includes a horizontal roadwheel and several horizontally rotatable tires which are urged against the roadwheel and rotated thereby. The tire spindle assembly is borne by a carriage which is movable toward and away from the roadwheel on a floating platform. The radial force with which the tire is urged against the roadwheel is offset by a linkage structure attached between the platform and the fixed base of the roadwheel assembly such that instantaneous rotation of the platform relative to the roadwheel base is about the axis of rotation of the roadwheel. The linkage structure includes a load cell for measuring the radial force. The arrangement further includes a load cell generally at the perimeter of the roadwheel which measures the tangential rolling resistance force of the tire.
