The wheel load balance of a railway vehicle could vary according to whether it is before or after the curve passage. The variation is influenced by the leveling valve (LV) that has a dead zone of air supply and exhaust. The purpose of this research is to clarify the mechanism of the wheel load variation due to the dead zone of the LVs. In this paper, we assume the situation where the lateral force is loaded and unloaded on the car body. The simulation and experimental results show that the diagonal difference in LV rod lengths and the maximum lateral force are related to the air spring pressure variation.
