Truck bolster










Image Number 3 for United States Patent #7681506.

A railroad car truck bolster may be formed as a steel casting. That bolster may include side bearing fitting access sockets located abreast of the side bearing seats. It may also include substantially continuous internal cavities to either side of a cross-wise internal vertical web plate mounted under the center plate bowl. The truck bolster may have large brake rod apertures that have large radii of curvature, and that may be bounded internally be a shear reinforcement at the vertical plane of the truck mid-span centerline, and another shear reinforcement spaced laterally outboard of the mid-span vertical plane. The webs of the bolster may be substantially imperforate outboard of the brake rod openings. The brake rod openings may have a profile that is large enough to accept either conventional or Wabco brake rods. The end portions of the truck bolster may include bolster pockets that have both primary and secondary wedge angles.
