摘要： A railway vehicle truck assembly (10) comprises wheel sets (12) having longitudinally spaced, transversely extending axles (18), and wheels (16) mounted to the axles (18); transversely spaced longitudinally extending truck frames (22, 24) mounted to the axles (18); and a transversely extending bolster (34) mounted to the truck frames (22, 24). The bolster (34) has a center bowl (36) and opposed, elongated bolster arms (38, 40) extending from the center bowl (36). An underslung equalizer beam (50) is located below the axles (18) and mounted to the axle boxes (35). Brake beam guides (54) are located in the equalizer spring seats (60) which are located on the underslung equalizer beam (50). The equalizer beam (50) is hot-box detector compatible so as not to interfere with the axle bearing detection scanners located alongside the railroad track.
