A railroad car wheel having an annular hub for connection to an axle and defining an inner radial surface adapted for disposition in facing relating to the inner surface of a wheel on the opposite end of the axle and an outboard radial surface facing outwardly of the wheel, an annular tread defining

A railroad car wheel having an annular hub for connection to an axle and defining an inner radial surface adapted for disposition in facing relating to the inner surface of a wheel on the opposite end of the axle and an outboard radial surface facing outwardly of the wheel, an annular tread defining rim portion disposed generally concentrically of the hub and defining an inner radial surface adapted for disposition in facing relation to the inner surface of a wheel on the opposite end of the axle and an outboard radial surface facing outwardly of the wheel, the rim portion being displaced axially outwardly with respect to the hub and including an outer, generally cylindrical rail engaging surface provided with radially extending flange adjacent the inner radial surface, and an integral annular plate portion connecting the rim and hub, the plate having a relatively thin cross section and being generally frusto-conical defining inboard and outboard conical surfaces, the plate joining the hub adjacent the inner radial surface with the inboard conical surface of the plate merging into the inner radial surface of the hub, the plate joining the rim with at least one of the inboard and outboard conical surfaces merging respectively with one of the inner radial outboard radial surfaces of the rim.

A railroad car wheel having an axially elongated annular hub for connection to an axle defining an inner radial surface adapted for disposition in facing relating to the inner surface of a coacting wheel on the opposite end of the axle and an outboard surface facing outwardly of said wheel; an axially elongated annular tread defining rim portion disposed generally concentrically of the hub and defining an inner radial surface and an outboard surface spaced therefrom, said rim being displaced axially outwardly with respect to said hub and having a rail engaging surface provided with a radially extending flange adjacent said inner radial surface, and an integral relatively thin sectioned plate portion connecting said hub and said rim, said plate being generally frusto-conical and defining an inboard conical surface and an outboard conical surface, said plate joining said hub adjacent said inner radial surface thereof with said inner conical surface of said plate merging directly into said inner radial surface.
