A wheel of lightweight construction useful as a wheel for a railroad car having a hub portion and a rim portion. The hub portion is connected to the rim portion by a pair of spaced apart opposed concavely shaped wheel discs positioned back-to-back. Each of the wheel discs has a main portion running between the hub and the rim. The main portion has integral therewith at each end thereof an arcuately shaped transitional portion which terminates in an edge. One of these transitional portions contiguously abuts and is affixed to one of two oppositely inclined flanks of the hub. The other of the transitional portions contiguously abuts and is affixed to one of two oppositely inclined flanks of the rim.
A wheel of lightweight construction useful as a railroad car wheel having a rigid hub portion and a rim portion, said hub portion connected to said rim portion by a pair of opposed spaced part concavely shaped wheel discs positioned back-to-back, each of which comprises a main portion running between said hub and said rim, which main portion has integral thereto at each end thereof an arcuately shaped transitional portion terminating in an edge, one of said transitional portions contiguously abutting and affixed to one of two oppositely inclined flanks of said hub, the other of said transitional portions contiguously abutting and affixed to one of two oppositely inclined flanks of said rim, the space between said opposed concavely shaped wheel discs being hollow, said hub and said rim each having facing parabolic contours on which said arcuately shaped transitional portions of said concavely shaped wheel discs are secured.
