  • Patent number: 11952019
    Abstract: A steering mechanism for a rail vehicle includes two steering arms, each including a pair of support arms that have a joining component with a recess. The two steering arms are articulated in a manner that maintains a minimum separation between the steering arms so that the arms can rotate relative to one another. The minimum separation is maintained by an insert that installs into the joining component recesses components of each of the steering arms. The insert has two sides, each side having a flexible material and forming a shape that mates with the recess. The insert provides resistance to the rotation between the first and second steering arms, and the resistance depends on the stiffness of the flexible material of the insert.

  • Publication number: 20070034108
    Abstract: Split wedges biased against sloped upper surfaces and the side walls of pockets in the ends of the bolster of a rail car truck are provided with non-metallic wear plates which interface with pocket side walls to reduce or eliminate pocket side wall wear. The wear plates are typically cast polymeric pads selected from the group comprising nylon, Delrin, UHMW and urethane, have a hardness in the range of between about 700° and 900° and a sliding coefficient of friction of about 0.10 to about 0.30. The pads are mounted in recesses within the sidewalls of the wedges and are held in place by means such as threaded fasteners for ease of replacement.
