    Abstract:

    The steering performances of wheels with different coupling modes are obviously different. The dynamics models of a bogie with traditional wheelset, independent rotating wheel, longitudinal coupling wheel and elastic damping coupling wheelset were established, respectively, and the guiding mechanism and the generation of longitudinal creep forces were analyzed. The results showed that the traditional wheelset can produce longitudinal creep forces with the same size and opposite direction and has the best guiding ability. Independent rotating wheels cannot generate longitudinal creep forces, and the guidance can be fulfilled only by the wheel edge when the train passes through curved lines. The longitudinal coupling wheel also can generate longitudinal creep forces with the same size and opposite direction, and its guiding ability is better than the independent rotating wheel. The generating mechanism of the longitudinal creep forces produced by the elastic damping coupling wheelset is almost consistent with that of the traditional wheelset, and its guiding performance is slightly worse than the traditional wheelset, but better than the longitudinal coupling wheel.
