Railcar brake beam wear liner

Abstract

A brake beam wear plate assembly for a railway car truck sideframe is provided. A brake beam wear plate is provided and adapted to be inserted in a brake beam guide which is typically an integral component of a railway car truck sideframe. The brake beam wear plate itself is comprised of a channel shaped body having an upper wall, a lower wall, and a bottom wall. The brake beam wear plate is typically comprised of a polymer or a high density plastic. The brake beam wear plate also includes a projecting locating tab and the brake beam guide itself includes a complimentary cutout section.

What is claimed is: 
     
         1 . A brake beam wear plate assembly for a brake beam guide on a railway car truck sideframe comprising a brake beam wear plate including a channel shaped body having an upper wall and a lower wall,
 and a bottom wall connecting the upper wall and the lower wall,   the brake beam wear plate fitted into the brake beam guide,   the upper wall of the bake beam wear plate including   a first lip extending laterally therefrom,   the lower wall of the brake beam wear plate including a second lip extending laterally therefrom,   the upper wall first lip of the brake beam wear plate including a locating tab protruding laterally therefrom,   the brake beam guide comprising an upper section and a lower section,   the upper section of the brake beam guide including a cutout section,   the locating tab of the brake beam wear plate being reviewed in the cutout section of the brake beam guide upper section.   
     
     
         2 . The brake beam wear plate assembly of  claim 1   wherein the locating tab protruding from the upper wall lip of the brake beam wear liner comprises of a semicircular shaped structure of a thickness similar to the upper wall first lip.   
     
     
         3 . The brake beam wear plate assembly of  claim 1   wherein the cutout section of the upper section of the brake beam guide comprises a semicircular shaped section.   
     
     
         4 . The brake beam wear plate assembly of  claim 1   wherein the brake beam wear plate is comprised of a polymer or a high density plastic.   
     
     
         5 . A brake beam wear plate rejection assembly for a brake beam guide on a railway car truck sideframe comprising a brake beam wear plate including a channel shaped body having an upper wall and a lower wall, and a bottom wall connecting the upper wall and the lower wall,
 the upper wall of the brake beam wear plate including   a first lip extending laterally therefrom,   a lower wall of the brake beam wear plate having   a second lip extending laterally therefrom,   the brake beam wear plate upper wall first lip including a rejection tab protruding laterally therefrom,   the brake beam guide comprising an upper section and a lower section,   the upper section of the brake beam guide including   a block structure extending therefrom,   the rejection tab of the brake beam wear plate contacting the block structure of the brake beam guide upper section to prevent the improper assembly of the brake beam wear plate into the brake beam guide.   
     
     
         6 . The brake beam wear plate rejection assembly of  claim 5   wherein the rejection tab protruding from the first lip of the upper wall of the brake beam wear plate comprises a rectangular shaped structure of a thickness similar to upper wall first lip.   
     
     
         7 . The brake beam wear plate rejection assembly of  claim 5   wherein the block structure of the upper section of the brake beam guide comprises a rectangular shaped structure extending from an outer surface of the upper section of the brake beam guide.   
     
     
         8 . The brake beam wear plate assembly of  claim 5   wherein the brake beam wear plate is comprised of a polymer or a high density plastic.
