Abstract: Various embodiments provide a stabilizing transom. Various embodiments provide a vehicle truck such as a railroad car truck including a first side frame, a second side frame, a bolster, and a stabilizing transom connected to the first side frame and the second side frame and configured to reduce, inhibit, minimize, and/or prevent truck hunting and warping.

Abstract: In order to achieve in a truck for a track vehicle with an H-shaped truck frame which consists of a composite fiber structure serving the function of a primary spring, with two longitudinal beams connected to each other via transverse beams, a distribution of the loads of the truck frame suitable for composite fibers, the frame contains a torsion-elastic central plate member which couples the longitudinal beams to each other independently of the transverse beams, is designed in the truck plane as a frame stiffening element, is provided with load introduction points for the longitudinal and transverse support of the vehicle body and is designed as a bending-stiff composite fiber component for the transmission of longitudinal and transverse forces between the load introduction points and the longitudinal beams.

Abstract: A transom, shaped in the form of an "I" beam, is welded between two side frames of a railway car. The web plate permits a small amount of twisting and relative weaving movements between the side frames in vertical directions to provide equalization.

Abstract: A rail-mounted conveyance wherein two undercarriages support a superstructure. One of the undercarriages is movable with reference to the superstructure about three axes including a substantially horizontal X-axis extending in the direction of travel of the conveyance, a substantially horizontal Y-axis which extends transversely of the direction of travel of the conveyance, and a substantially vertical Z-axis which is normal to the other two axes. Movements about the X-axis are made possible by providing the one undercarriage with a transverse axle which defines the Y-axis and carries a block having a convex top surface sloping from the center toward both sides of the one undercarriage, and by providing the superstructure with a platform having a flat underside which abuts against and can roll along the convex surface. The line of contact between the block and the platform defines the first axis.

Abstract: A freight car truck side frame-bolster connection which provides self-squaring or self-tramming forces by resilient means incorporated in bearing shoes that cooperate with the bolster ends and the side frame window opening to produce the desired results. Also, the provision of the resilient squaring force is accomplished while maintaining the ability to shim at the bolster ends for adjustment of car height, and without the need for close tolerances.
