The present hub devices simulate the situation where the tire is driven on a straight road surface under a constant pressure, since the constant pressure is applied to roll the tire against the hub surface, which can be understood as a flat surface without a line. However, it is difficult for such a device to simulate the impact of the bump vibration, the pit or the threshold to which the tire is subjected in actual running, and such impact has a large influence on the life of the tire for the wheel. If these impact load conditions are ignored, large deviations can be made in the life prediction or performance analysis. However, the modification of the variable pressure by the thrust device of the existing equipment is not only expensive, but also difficult to simulate the rapid changing force applied to the tire when the tire is impacted, so that the existing equipment cannot meet the requirement of generating impact load.
