Abstract
A multi-axle railroad car truck or bogie is described as having two very important features; namely, a suspension and snubbing mechanism associated with each axle end to cushion, isolate and dampen vibrations imparted to the axles, and a device for mounting each saddle on an associated pedestal for swinging in a generally vertical plane, such that the axles held captive by the saddles, will each independently move laterally in either of a pair of opposing directions of from 1" to 11/4", measured from a center plane midway between the side frames, when the truck is horizontally disposed in a rest position. Further, the saddles are mounted such that each axle end can move independently in either of a pair of opposing directions of from 3/8" to 1/2", measured from a fixed vertical plane which includes the longitudinal axis of the axle, when the truck is horizontally disposed in the rest position. Further described is a rigid framework for distributing loads to the axles of a tri-axle truck or bogie.
