IMPROVED STEERING ARM ASSEMBLY FOR A RADIALLY STEERABLE RAILWAY CAR TRUCK

摘要

A steering assembly for a radially steerable articulated railway car truck has a pair of steering arms that are operably joined to the truck axles and connected together by a linkage passing over the truck bolster adjacent the side frames. The steering arms can be retrofitted to an existing conventional (non-radially steerable) three piece railway truck regardless of the type of brake rigging the truck employs. The linkage structure includes a pivotable link located at each end of the bolster and joining the steering arms for articulated movement.
