Abstract
A load transducer used for determining loads on a tire in a tire testing apparatus has very high stiffness and a high natural frequency. A tire support spindle has an end plate mounted on one end of the transducer on a center support sleeve which is supported relative to an outer housing at spaced locations in direction along the wheel rolling axis. The support sleeve is supported relative to the outer housing at each end by four arms or beams that operate as shear beams in reaction to the vertical and rolling loads on the tire, and the corresponding moments created by these two forces or loads. Forces on the tire at the tire rolling radius parallel to the rolling axis of the tire are also measured by bending the support beams.
