Abstract
A radial axle railway truck has a pair of depressed center side frames supported at their ends from the axles by horizontal elastomeric pad devices carried on the sides of outboard journal bearing adapters to permit steering movements of the axles, the horizontal pad devices nearest the ends of the side frames being elongated transversely of the truck and the horizontal pad devices remote from the ends of the sideframes being elongated longitudinally of the truck. A transverse truck frame is supported at each side above the depressed center portion of the respective side frames by a pair of generally V-shaped elastomeric pad devices supported on the inclined portions of the side frames connecting the high end portions and the depressed center portions thereof. Both journal bearings on each of the respective axles are connected by a yoke member extending toward the center of the truck and both yoke members are in turn connected by diagonal links to provide equal and opposite turning movements of the axles responsive to yaw and steering movements of the axles. Each axle mounts at least one brake disc and the mechanism therefor is supported from the respective axles and includes shoes underlying the respective axles, each mechanism being connected to the truck frame to transmit braking torque thereinto in a longitudinal direction only and thus oppose inertial longitudinal movement of the truck frame with respect to the axles during retardation of the axles, without interfering with steering movements of the respective axles.
