(54) Railroad car bogie


(57) A railroad car bogie (10) comprising spaced wheelsets (12, 14) has axle ends (16) of each wheelset journaled in bearings (18, 22) which in turn are carried respectively by an adapter (24. 26). Each adapter is connected to a side portion (34) of a U-shaped steering arm (28,30) so as to form a wheelset-steering arm unit (35, 37). Elastomeric devices (40) join the side portions (34) of the steering arms (28, 30) to pedestal jaws (46, 48) formed at ends of a pair of spaced side frames (50, 52). Interposed between the wheelset-steering arm units (35, 37) is a connecting device (78) joining the steering arms (28, 30) at a central location proximate to a bolster (58) of the bogie (10).
