Abstract
In accordance with the invention a center filler assembly is inserted into a railway car center sill and is permanently attached to the center sill. The center filler includes longitudinally spaced vertical plates which extend between the walls of the center sill. Spacer extensions integral with the vertical plates extend beyond the walls of the center sill and abut the bottom surface of the center sill flanges. A mounting plate extends longitudinally of the car between the center filler vertical plates. A mounting extension portion extends downwardly from the mounting plate having a non-round contour adopted to engage a cooperating non-round opening located in a wear member to be located in the truck bowl. Interengaging means are provided to removably lock the wear member in engagement with mounting plate and/or the mounting plate extension. The wear member is preferably an elastomeric member having sufficient vertical compressive strength to carry the vertical loads between the car body and the truck, sufficient lateral compressive strength and sufficient shear strength to carry the horizontal loads between the truck bowl and the car body. In another embodiment the wear member is made of metal. A thin layer of elastomeric material is provided between the mounting plate and the wear member to transmit loads more uniformly between the metal mounting plate and the metal wear member. As an example an elastomeric epoxy coating may be applied to the mounting plate and mounting extension and/or the metal wear member.
