In driving bogies of railway vehicles, motors and driving devices are often arranged not in left‐right symmetry, but in point symmetry. In such cases, roll motion of the bogie frame tends to occur when the motors are driven and result in wheel load imbalance. However, few studies have focused on this roll motion of the bogie frame. In this study, the effect of the roll motion of the bogie frame on the wheel load imbalance on the left and right is examined, using parallel Cardan driving bogies as the subject. A one-vehicle model with parallel Cardan driving bogies is constructed using multibody dynamics. The simulation results show that the roll motion of the bogie frames causes lateral displacement of the car body. This lateral displacement causes an imbalance in wheel loads on the left and right sides of the wheelsets. It is found that this phenomenon also occurs under conditions where wheel slips occur and the re-adhesion control is in operation.
