    摘要： A side bearing unit for attachment to a bolster of a truck of a railroad car has a base which may be fastened to a top wall of the bolster. A housing, carried by the base, includes spaced sidewalls joined by end walls to define a cavity for an elastomeric device. A cap, positioned within the housing, is integrally joined to the elastomeric device with a top surface of the cap located above the housing for engagement with a wear plate attached to a bottom of a body of the car. During travel of the railroad car, sets of side bearing units are particularly effective in regulating independent rolling of the car body as well as impeding truck hunting.

    摘要： A freight vehicle having a bogie with a primary suspension having a stiffness which increases with applied load. A secondary suspension between the bogie and the vehicle body is of lower stiffness then the primary suspension and permits torsional movement of the suspension relative to the vehicle.

    摘要： A preloadable side bearing for railroad cars having a mass of hard elastomeric material on a base adapted for attachment to a supporting surface, such as the truck bolster of a railroad car with provision for an initial reduction in the overall height of the bearing in response to preloading forces and to then absorb substantial loading forces with resulting compressive depression of the mass and wherein the mass is formed of a material such as polyurethane.
