ABSTRACT:
A railroad car truck may be assembled by spacing a pair of side frames to which is connected a transversely positioned bolster. End portions of the bolster are located within a window formed in a middle portion of each side frame to form a connection therebetween. Each side frame-bolster connection includes vertical cushioning provided by a set of coil springs interposed between a lower compression member of the side frame window and a bottom wall of the bolster. To damp the vertical cushioning of the bolster a pair of friction shoes carried by the bolster interact with wear plates fastened to vertical columns of the windows. The friction shoes impede bolster rotation which is maintained between fixed limits by contact between adjacent structural members of the bolster and side frame. To prevent undue flexing of the side window columns a stiffening rib may be selectively added to the columns.
