摘要： A height compensation device for a railway truck having at least two pairs of rail engaging support wheels. The height compensation device is secured at opposed ends of a truck bolster and compensates for car body height loss after the wheels are re-profiled. The compensation device comprises a bearing element having a top support surface on which the car body rests. A displaceable height adjustment plate having one or more shim sections of different thicknesses is provided with one of the sections being disposed between the bearing element and the truck bolster by lifting the car body off the bearing element whereby to dispose the top support surface of the bearing element at a predetermined desired height above the truck bolster to maintain the car body at a substantially constant height from track level after wheel profiling.

摘要： In a truck assembly for a railway vehicle wherein the assembly has a truck frame defined by opposed side frame sections and a transom section extending transversely between the side frame sections and substantially at mid-length thereof. A pair of wheels are supported between opposed ends of the side frame sections. A truck bolster assembly is supported above the transom for supporting a cab thereon. The bolster assembly is retained in position relative to the transom by a central pivot. The improvement comprises side bearing height adjusters which are removably secured between the truck frame and the truck bolster assembly and spaced from the central pivot on a respective side thereof. The side bearing height adjusters have a bearing element with a top friction support surface to permit horizontal displacement of the bolster assembly about the central pivot.
