A Study on the Performance of Swing Motion Bogie to Applicable to High-Speed Freight Car

초록

Swing Motion Bogie(SMB) allows the bolster to move ±32mm laterally. The swing motion occurs between the pedestal and adapter while the transom connected with sideframe on the rocker seat each side, moves laterally, thus allowing each part to cooperate swing motion movement. Large face area of the wear plate, fastened on the side frame and contact with the friction wedge, provide with absorbability of force from the vertical movement of suspension and the lateral movement of the transom. Transom maintains the truck's H shape as does the H-frame bogie. Also, as there is no gib on the bolster which requires most frequent maintenance, the bolster is free from movement of the side frame. Instead, lateral stops that are located upward on transom and bottom of the bolster touches each other. This design allows impact point at lower location and extended lateral movement. Lowered center of the lateral movement reduces the wheel load reduction, thus reducing chance of derailment."
