Patent

CA 2377552

A railway car truck having a pair of side frames and a bolster and a transom extending transversely between the side frames. A respective rocker seat is rigidly and permanently attached to each end of the transom and is pivotally supported on a rocker bar that is supported by the tension member of a sideframe. The pivotal connection between the rocker seat and the rocker bar disposes the transom perpendicular to the side frame and provides pivotal movement of the side frame with respect to the transom. The railway car truck is assembled by inserting the ends of the bolster and transom into the window of a side frame, and then inserting the rocker bar through a passageway in the side frame to a position under the rocker seat and on the bottom tension member of the side frame. Springs are then inserted between the transom and the bolster such that the bolster is resiliently supported on the side frame.
