ABSTRACT:
A railroad truck includes a pair of side frames with wheeled axles mounted there between. A roller bearing adaptor is mounted upon a roller bearing at each end of each axle with the side frames being mounted upon a shear pad mounted on the roller bearing adaptors. There is a subframe for interconnecting the wheeled axles by connecting opposite corner adaptors and there is a rigid connection between each adaptor and the subframe. Each rigid connection includes an adaptor portion and a subframe portion, with said portions being relatively vertically disposed. There are vertical fastening means connecting said vertically disposed adaptor and subframe portions. The vertically disposed portions have cooperating means thereon which substantially eliminate horizontal shear forces upon the fastening means.
