摘要： A side frame (8) for a railway car comprises a pedestal jaw (10) and an integral crown shaped pedestal jaw roof (20). A snap-on liner (28) matching the shape of the crowned pedestal jaw roof (20) is removably mounted to the pedestal jaw roof (20). In operation, the crown shaped pedestal jaw roof (20) and snap-on liner (28) reduce wear on the pedestal jaw roof (20) and permit swinging of the side frame (8) relative to railcar axles. The integral crown shaped pedestal roof (20) and snap-on liner (28) eliminate the traditional rocker seat, shims, and welded retainers, thereby reducing the maintenance and cost of traditional side frames.

摘要： A lightweight truck bolster (10) for railway car trucks has metal removed in the compression member (18) and tension member (20) of the bolster (10) near the center bowl (12) of the bolster (10). The bolster (10) includes one longitudinal rib (48) located in each end of the bolster arms (14, 16) and a pair of transversely extending vertical ribs (30) located on opposing sides of the center bowl (12) and extending from the tension member (20) to the compression member (18). The bolster (10) satisfies the Association of American Railroads (A.A.R.) design qualifications for truck bolsters while it is weighing significantly less than traditional truck bolsters.

摘要： A coupler (10) is provided for a railroad rotary dump car (2, 4 and 6). The coupler (10) comprises a housing (16), a coupler head (12), a buff loading shim (90), and as most preferred, a plurality of spring tab fasteners (212). The coupler housing (16) defines a coupler cavity with a cavity end (216). The coupler head (12) has a spindle (14), is mounted to the coupler housing (16), and is adapted for rotary movement relative to the housing (16). The spindle (14) has a spindle end (72) adjacent the cavity end (216). The shim (90) interposes the spindle (14) and the cavity end (216). The spring tabs (202) are spaced one from another. Each includes a spring portion (210) and a fastener portion (212). The fastener portions (212) provide for removable fastening of the spring tabs (202) to the coupler housing (16). The spring portions (210) bias the shim against the cavity end (216) and away from the spring tabs (202). The spring portions (210) are curved relative to the fastener portions (212). The spring tab fasteners (202) removably fasten the spring tabs (202) along the fastener portions (212) to the coupler housing (16) adjacent the shim (90). Among other advantages, the shim (90) is positioned and spring biased for abutment by the spindle end (72) and against the cavity end (216) in buff loading and upward and against the cavity end (216) for increased life and reduced wear and damage. Also, the spring tabs (202) may be removed and the shim (90) removed and replaced as necessary due to wear of all components.

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.

摘要： A disc brake assembly for a railway truck is provided. The truck (10, 11) includes at least two wheel axle sets (22, 23) and brake discs (12, 13) mounted to the wheel axle sets (22, 23). Extending between the wheel axle sets (22, 23) is a longitudinally extending truck frame (20, 21). Also extending between the wheel axle sets (22, 23) and supporting the truck frame (20, 21) via primary springs (65) are equalizer beams (64) that further extend beyond the wheel sets (22, 23) and through an opening (70) in the truck frame (20, 21). Disc brake calipers (62) are mounted to the equalizer beams (64) with the caliper (62) engaging the brake discs (12, 13) of the wheel sets (22, 23). The assembly results in the brake discs (12, 13) and calipers (62) being unsprung. In other words, the brake discs (12, 13) and calipers (62) do not move relative to each other.
