Abstract: A railroad freight car brake beam with a strut having a pair of generally parallel and joined side walls disposed to opposite sides of an axis of the strut and having a central hollow portion along with a longitudinally elongated slot adapted to be inclined a predetermined number of degrees from vertical for accommodating an elongated brake lever extending through the strut. Each side wall of the strut defines a bore opening to the hollow center portion and to an exterior of the strut. The bores defined by the strut are aligned relative to each other to accommodate at least a lengthwise portion of a brake lever pivot pin extending through the strut and serving to connect the brake lever to the strut. The aligned bores in the strut also define a pivot axis for the brake lever. The strut further includes a pair of bushings which journal the brake lever pivot pin. One bushing is accommodated in each bore defined by the strut.

Abstract: A railroad freight car brake beam strut assembly including an elongated strut having first and second joined walls. Each wall of the strut defines a bore opening to a hollow center portion and to an exterior of the strut. The bores defined by the walls on the strut accommodate a brake lever pivot pin extending through strut thereby connecting the brake lever to the strut and so as to allow pivoting of the brake lever. Each bore defined by the walls of the strut has a closed marginal edge. One brake pin bushing is accommodated in each bore defined by the strut so as to journal a lengthwise portion of the brake lever pivot pin.

Abstract: A brake beam structure comprising compression and tension members having an “u” shaped cross section including two side walls and forming a housing, two end extensions having a quadrangular cross section including two side walls, a fulcrum coupled to the compression and tension members and two brake heads, in which: the ends of the compression member are placed inside the housing of the unshaped cross section of the tension member and each of the end extensions are placed inside the housing of the channel shaped cross section of the compression member, the brake beam having two fasteners passing through holes placed at the ends of the tension and compression members at each of “u” shaped cross section side walls and through holes placed at the side walls of the end extensions in order to fasten the tension member, compression member and end extensions, and in which the brake heads are welded to the ends of the tension member.
