Summary: the two kinds of bogie is suitable for the Brazil MiGui or broad gauge lines running on the railway wagon. Three big type bogie structure of cast steel, the use of a pillow spring suspension and often friction wedge type damping device, increase the wedge Lord vice friction surface width, in order to improve current stiffness. It mainly consists of the wheel and the bearing assembly, bolster and side frame composition, elastic suspension and damping device, foundation braking device and side bearing, etc.
