Railway bogie pivotal connection system - performs radial steering of individual wheel axles when bogie turns relative to carriage body

摘要

A railway bogie assembly has a bolster and bolster drag links operatively connecting the opposite ends of the bolster to a railway carriage body. It has a pair of spring suspension positioned on the opposite lends of the bolster and operatively carrying the car body. It has a pair of wheel axles and a pair of steering yokes rotatively holding the wheel axies respectively and pivoted one to the other about a vertical axis, between the wheel axies. A pair of side frame is positioned at the opposite ends of the bolster. Pivots are used for connecting the side frame at one end of the yoke respectively. There are lateral links pivotally connecting at least one side frame to the bolster, and a steering crossbar having a central portion pivotally connected to one of the yokes.
