Abstract:
1. A wheel test assembly for testing a wheel-and-tire assembly, said wheel test assembly comprising: a base; a cylindrical drum operatively mounted to said base, said drum including an inner circumferential surface defining a first rotational axis, said drum rotatable about said first rotational axis; a tailstock assembly slidably coupled to said base, said tailstock assembly slidable in a lateral direction relative to said drum; a support assembly slidably coupled to said tailstock assembly, said support assembly slidable in a vertical direction for positioning the wheel-and-tire assembly into rolling contact with said inner circumferential surface of said drum; and a spindle assembly pivotally coupled to said support assembly, said spindle assembly pivotal about a pivot axis to adjust a camber angle of the wheel-and-tire assembly, said pivot axis extending in a direction normal to said lateral direction and normal to said vertical direction, the wheel-and-tire assembly rotatably mounted to said spindle, the wheel-and-tire assembly rotatable about a second rotational axis in response to rolling contact with said inner circumferential surface of said drum.
