ABSTRACT:
A railway flat car is supported on an underframe which includes suspension support frames provided with single axle suspensions. The frames include longitudinally spaced bolsters including horizontal frame structures on which leaf springs are supported which are also carried by journals supporting the single axles. The ends of the leaf springs are supported by vertical spaced hanger straps pivotally connected at their lower ends to support brackets which are fixed to the bolster structures of the support frames. In the present improvement the brackets are welded into recesses provided in the bolsters providing an improved structure minimizing stress problems. The brackets become an integral part of the bolster structures.
