Alignment adjustment wheel vehicles with comparative measurements of lateral forces.

摘要

The wheel angle of a vehicle is adjusted according to the characteristics of the tire wheel so that the vehicle direction is substantially neutral. the wheel angle of a reference wheel vehicle (for example, a rear wheel) is adjusted. Then, the reference wheel and a wheel no reference (for example a front wheel) on the tire surface drive an endless track on which a plurality of protuberances formed as plates of a predetermined height are rotated . Then the longitudinal and lateral forces generated in the tire are measured. Based on the waveforms of the rate of change measured in the longitudinal forces, determined in a predetermined time from the time the tire is deformed period when the wheel passes over the upward step of the bump until the tire is deforms when the wheel passes over the step-down extrusion, lateral forces are measured within a predetermined period. waveforms of the lateral forces of both wheels indicated by the extracted data, and the direction in which the toe angle of the wheel no reference should be set is calculated on the difference between the waveforms overlap.
