  • Patent number: 8602181
    Abstract: A method of manufacturing a railroad freight car brake beam strut assembly including the steps of: providing a railroad strut having an elongated slot defined between first and second sides of the strut, with each side of the strut defining a bore opening to the slot and to an exterior of the strut. The bores defined by the strut are aligned relative to each other along an axis. The methodology of the present disclosure further includes the step of: pressing a brake pin bushing into each bore of the strut in a direction extending away from the longitudinal axis of the strut with each brake pin bushing having first and second ends, and wherein a periphery of each bushing has a frusto-conical surface configuration. A railroad freight car strut assembly is also disclosed.

  • Patent number: 8225912
    Abstract: A method of manufacturing a railroad freight car brake beam strut assembly including the steps of: providing a railroad freight car brake beam strut having an axially aligned slot defined between first and second sides of the strut, with each side of the strut defining a bore opening to the slot and to an exterior of the strut, with the bores defined by the strut being aligned relative to each other along an axis extending generally normal to a longitudinal axis of the strut. The methodology of the present disclosure further includes the step of: pressing a brake pin bushing into each bore of the strut in a direction extending away from the longitudinal axis of the strut. A railroad freight car strut assembly is also disclosed.
