Abstract:
A testing machine includes a frame and a roadway assembly. The roadway assembly includes an endless belt and a carriage supporting the endless belt for rotation on the carriage and providing flat portion in the endless belt. The carriage is pivotally coupled to the frame to move relative to the frame about at least one axis. The carriage includes a bearing arranged to support an inner surface of the flat portion of the endless belt. A spindle carriage has a spindle arranged to support a tire and wheel assembly. The spindle carriage is movably mounted on the frame to move the spindle toward and away from the flat portion. A drive is operably coupled to the roadway assembly or the spindle. An actuator controls pivotal movement of the roadway assembly about said at least one axis. A method of ascertaining rolling loss of a tire mounted to such a machine is also provided.
