PEDESTAL LINER FOR A RAILWAY VEHICLE AND METHOD OF MAKING SAME

摘要

An improvement is provided on a pedestal liner for a railway vehicle and in the method for making such liner. The railway vehicle comprises pedestal trucks comprising pairs of pedestal legs and a journal box disposed between each pair of pedestal legs, each journal box having a vertically disposed planar central guide surface and a pair of spaced vertically disposed parallel side surfaces disposed on opposite sides of said guide surface. The pedestal liner is roughly U-shaped having a bight and a pair of parallel legs and being for disposal between an associated pedestal leg and journal box. The pedestal liner includes a continuous uninterrupted metal backing material defining said bight and parallel legs. Antifriction material in the form of an ultra high molecular weight polymeric material is provided for said bight and is adapted to engage the guide surface. Antifriction material in the form of an ultra high molecular weight polymeric material is provided for said parallel legs and is adapted to engage the side surfaces. Means are provided for fixing the antifriction material against the bight and parallel legs of the backing material. In this way, the backing material provides optimum structural support for the antifriction materials.
