| A rail road freight car truck has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The mounting interface between the ends of the axles and the sideframe pedestals allows lateral rocking motion of the sideframes in the manner of a swing motion truck. The lateral swinging motion is combined with a longitudinal self steering capability. The self steering capability may be obtained by use of a longitudinally oriented rocker that may tend to permit resistance to deflection that is proportional to the weight carried across the interface. The truck may have auxiliary centering elements mounted in the pedestal seats, and those auxiliary centering elements may be made of resilient elastomeric material. The truck may also have friction dampers that have a disinclination to stick-slip behavior. The friction dampers may be provided with brake linings, or similar features, on the face engaging the sideframe columns, on the slope face, or both. The friction dampers may operate to yield upward and downward friction forces that are not overly unequal. The friction dampers may be mounted in a four-cornered arrangement at each end of the truck bolster. The spring groups may include sub-groups of springs of different heights. | ||||||

| A steering truck for steering a wheel axle of a truck has a solid lubricant application device at a position facing a flange of a wheel on the outer side of the wheel axle in the direction of travel in a truck frame. A solid lubricant is applied to freely make contact with and move away from the flange and a spring impels the solid lubricant towards the flange. A stopper restrains the solid lubricant from approaching the flange, By utilizing a forward and backward movement of the wheel axle in the travel direction caused by steering, the solid lubricant 3 makes contact only on the outer rail side toward which the wheel approaches when passing through a curved section. No contact occurs on the inner rail side from which the wheel moves away when passing through a curved section and when traveling through a straight section. | ||||||
