摘要： A railcar brake beam assembly including a brake beam formation having a tension member, a compression member and strut, and with the strut defining an axis for the brake beam assembly. First and second brake head assemblies are disposed to opposite lateral sides of the axis, with each brake head assembly being operably carried by the brake beam formation and includes a guide member extending in a direction away from the axis. The first and second brake head assemblies are generally centered laterally relative to the axis of the brake beam assembly. A distal end of the guide member on the first brake head assembly is disposed a different lateral distance from the axis of the brake beam assembly than is a distal end of the guide member on the second brake head assembly to minimize lateral shifting movements while maintaining adequate clearances for permitting reciprocal moments of the brake beam assembly during application of braking forces. A method of designing a brake beam assembly for a railcar is also disclosed.

摘要： A railcar brake head having an upper end, a lower end, and a pair of sides. The brake head further includes an elongated concave keyway defining an elongated axis and opening to the upper and lower ends of the brake head. At least a portion of the keyway is defined between a rear wall and spaced transversely extending upper and lower lugs. A front surface of each lug is adapted for mounting engagement with a brake shoe. The longitudinal spacing between the centralized upper and lower lugs is such that a keybridge extending from a rear face of the brake shoe is received and accommodated therebetween whereby inhibiting endwise movement of the brake shoe relative to the brake head. The centrally disposed upper lug on the brake head is configured with a camming surface, a longitudinal portion of which is arranged relative to the keyway for guiding and facilitating movement of a free end of an elongated key downwardly past the upper lug whereby permitting the key to establish a proper locking relation with the keybridge of the brake shoe.

摘要： 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. Cooperating instrumentalities inhibit inadvertent displacement of the brake pin bushings away from the axis of and relative to the strut thereby fixing the pivot axis of the brake lever relative to the strut.
