US 2013/0199407 A1 · HIGH FRICTION RAILROAD CAR COMPONENTS WITH FRICTION MODIFYING INSERTS

Abstract

High friction railroad car components with component friction modifying inserts which are configured to coat an engagement surface on a corresponding component on the railroad car to modify or control the friction between an engagement surface of the high friction railroad car component and the engagement surface of the corresponding component while allowing such components to engage each other. The initial movement of the high friction component with the friction modifying inserts causes transfer material of the friction modifying inserts to be spread over or coat a portion of the engagement surface of the corresponding component. This forms a lubrication layer which modifies or controls the friction between these components while these components are in engagement.

Dependent claims

A high friction railroad car component for a railroad car, said component comprising:

a body having a high friction surface, said surface defining a plurality of friction modifying insert receiving pockets, said surface configured to engage a surface of a corresponding component;
and
a plurality of friction modifying inserts respectively positioned in said pockets, such that when said high friction surface engages said surface of the corresponding component for a period of time during use of the railroad car, said friction modifying inserts provide a lubrication layer on the surface of the corresponding component.
