Frame for railway truck

摘要

A frame for use with a railway truck may have a pivot housing, a first arm member extending outward from the pivot housing and having opposing distal ends, and a second arm member substantially identical to the first arm member and extending outward from the pivot housing opposite the first arm member. Each of the first and second arm members may have a generally planar upper plate, a generally planar lower plate, and plurality of webs vertically disposed between the generally planar upper and lower plates. An upper surface of the pivot housing may be generally co-planar with the generally planar upper plates of the first and second arm members.

1. A frame for a railway truck, comprising:
a pivot housing; a first arm member extending outward from the pivot housing and having opposing distal ends; a second arm member substantially identical to the first arm member and extending outward from the pivot housing opposite the first arm member; and brackets disposed at the distal ends of the first and second arm members, wherein the brackets disposed at the distal ends of the first arm member face inward toward the brackets disposed at the distal ends of the second arm member, wherein:
each of the first and second arm members includes a generally planar upper plate, a generally planar lower plate, and plurality of webs vertically disposed between the generally planar upper and lower plates;each of the brackets includes a first base plate with a rear face attached transversely to each forwardly facing end face of the distal ends of the first and second end members and a second base plate on the first base plate and extending outward from the forwardly facing end face of the first base plate along a longitudinal direction of the first and second arm members; andan upper surface of the pivot housing is generally co-planar with the generally planar upper plates of the first and second arm members.
