A truck for a railway vehicle including wheelsets each comprising a pair of wheels with an axle rigidly joining the wheels. A bearing assembly is provided at each end of the axle. A side frame having a pedestal jaw at each end accommodates therebetween one of the bearing assemblies, with the bearing assembly including an adapter member. The truck further includes a steering assembly operatively connected to the bearing adapter and thereby to the wheelset for radially steering the truck. The adapter member includes a main body portion underlying the pedestal jaw of the side frame, and an extension section extending axially of the axle inward from the main body portion towards the center of the truck. The adapter member extension section includes an upwardly facing, generally planar surface underlying a steering arm of the steering assembly. The arm is connected to and supported by the surface. Two spaced buttress type ribs project upward from the surface to receive the steering arm therebetween.
In a truck for a railway vehicle, a set of wheels and an axle rigidly joining said wheels, bearing assembly at each end of said axle, a first side frame having pedestal jaws accommodating therebetween one of said bearing assemblies, a second side frame having pedestal jaws accommodating the other bearing therebetween, said bearing assemblies each including a bearing adapter member and a steering arm for radially steering said truck operatively connected to said axle wherein said adapter member includes a main body portion underlying the roof of said pedestal jaws of said side frame and an extension section extending axially inward from said main body portion toward the center of said truck parallel to said axle and having an upwardly facing generally planar surface underlying said steering arm, and means maintained in compression for connecting said steering arm to said surface whereby the arm is supported on the surface.
