Abstract

Various embodiments provided a railroad car brake beam wear guide for mounting in a brake beam guide bracket of a railroad car truck side frame and including a spacer that partially defines a slide-way for a brake beam lug of a brake beam and that limits lateral movement of the brake beam. In various embodiments, the wear guide can be employed for other uses besides for railroad cars.

First claim

The invention claimed is:

1. A railroad car brake beam wear guide, comprising:
a longitudinally extending first wall;
a longitudinally extending second wall spaced apart from the first wall; and
a longitudinally extending end wall monolithically formed with and connecting the first wall and the second wall, the end wall forming a spacer, wherein the first wall, the second wall, and the spacer define a slide-way configured to permit movement of a lug of a brake beam in the slide-way, wherein the spacer is of a same longitudinal length as the first wall and the second wall, wherein the spacer has uniform dimensions along a longitudinal axis of the spacer, and wherein the spacer is configured to limit lateral movement of the brake beam.

2. The railroad car brake beam wear guide of claim 1 , wherein the end wall includes: (1) a longitudinally extending first section; (2) a longitudinally extending second section; (3) a longitudinally extending third section; (4) a longitudinally extending fourth section; and (5) a longitudinally extending fifth section, wherein the longitudinal axis of the spacer is parallel to a longitudinal axis of the slide-way, and wherein the spacer has an unaltered cross-sectional shape along an entire length of the first wall and the second wall.

3. The railroad car brake beam wear guide of claim 2 , wherein: (1) the first section is connected to and monolithically formed with a bottom portion of the first wall and is connected to and monolithically formed with the second section; (2) the second section is connected to and monolithically formed with the first section and is connected to and monolithically formed with the third section; (3) the third section is connected to and monolithically formed with the second section and is connected to and monolithically formed with the fourth section; (4) the fourth section is connected to and monolithically formed with the third section and is monolithically connected to and formed with the fifth section; and (5) the fifth section is connected to and monolithically formed with the fourth section and is connected to and monolithically formed with a bottom portion of the second wall.

4. The railroad car brake beam wear guide of claim 3 , wherein: (1) the first section extends inwardly from the first wall toward the second wall; (2) the second section extends inwardly from the first section toward a lip of the second wall; (3) the third section extends inwardly toward the first wall and extends inwardly toward the second wall; (4) the fourth section extends inwardly from the fifth section toward a lip of the first wall; and (5) the fifth section extends inwardly from the second wall toward the first wall.

5. The railroad car brake beam wear guide of claim 4 , wherein the third section extends in a plane closer to the lips extending from the first and second walls than a plane in which the first section and the fifth section extend.

6. The railroad car brake beam wear guide of claim 5 , wherein the second, third, and fourth sections of the end wall form the spacer and are spaced apart from each of the first wall and the second wall.

7. The railroad car brake beam wear guide of claim 6 , wherein the second, third, and fourth sections of the end wall that form the spacer are of a smaller width than a width from the first wall to the second wall.

8. The railroad car brake beam wear guide of claim 2 , wherein the second, third, and fourth sections of the end wall form the spacer and are spaced apart from each of the first wall and the second wall.

9. The railroad car brake beam wear guide of claim 2 , wherein the second, third, and fourth sections of the end wall form the spacer and are of a smaller width than a width from the first wall to the second wall.

10. A wear guide, comprising:
a longitudinally extending first wall;
a longitudinally extending second wall spaced apart from the first wall; and
a longitudinally extending end wall monolithically formed with and connecting the first wall and the second wall, the end wall forming a spacer, wherein the first wall, the second wall, and the spacer define a slide-way configured to permit movement of a lug in the slide-way, wherein the spacer is of a same longitudinal length as the first wall and the second wall, and wherein the spacer has uniform dimensions along a longitudinal axis of the spacer.

11. The wear guide of claim 10 , wherein the end wall includes: (1) a longitudinally extending first section; (2) a longitudinally extending second section; (3) a longitudinally extending third section; (4) a longitudinally extending fourth section; and (5) a longitudinally extending fifth section, wherein the longitudinal axis of the spacer is parallel to a longitudinal axis of the slide-way, and wherein the spacer has an unaltered cross-sectional shape along an entire length of the first wall and the second wall.

12. The wear guide of claim 11 , wherein: (1) the first section is connected to and monolithically formed with a bottom portion of the first wall and is connected to and monolithically formed with the second section; (2) the second section is connected to and monolithically formed with the first section and is connected to and monolithically formed with the third section; (3) the third section is connected to and monolithically formed with the second section and is connected to and monolithically formed with the fourth section; (4) the fourth section is connected to and monolithically formed with the third section and is monolithically connected to and formed with the fifth section; and (5) the fifth section is connected to and monolithically formed with the fourth section and is connected to and monolithically formed with a bottom portion of the second wall.

13. The wear guide of claim 12 , wherein: (1) the first section extends inwardly from the first wall toward the second wall; (2) the second section extends inwardly from the first section toward a lip of the second wall; (3) the third section extends inwardly toward the first wall and extends inwardly toward the second wall; (4) the fourth section extends inwardly from the fifth section toward a lip of the first wall; and (5) the fifth section extends inwardly from the second wall toward the first wall.

14. The wear guide of claim 11 , wherein the second, third, and fourth sections of the end wall form the spacer and are spaced apart from each of the first wall and the second wall.

15. The wear guide of claim 11 , wherein the second, third, and fourth sections of the end wall form the spacer and are of a smaller width than a width from the first wall to the second wall.
