Abstract
Official abstract text for this publication.
A stabilized railway car truck consists of two side frames and a holster. The bolster has laterally opposite ends, each end extending into and supported within a side frame opening on a spring group. The stabilized railway car truck also includes a transom extending into, and supported within, a side frame opening. The spring group is supported at each transom end. Each side frame has a pedestal opening at each end that receive a rotating lug to accept a elastomeric steering pad and bearing adapter. The attachment of the side frames and transom is a rigid pivotal connection. Friction shoes between the side frames and bolster provide damping of an initial low to a high rate friction once engaged. The pivotal decoupling of the side frame and transom, and the lateral movement of the friction shoes to the bolster, eliminates track displacement irregularities from reacting at the bolster and into the vehicle.
