Embodiment Construction

[0016] The present application describes an embodiment for attaching a wear plate to a wear surface of a railcar truck bolster. In particular, this application describes a bolster wear plate attachment surface that allows the use of multiple bolts of different lengths to bolt the wear plates. A shorter bolt extends through the upper hole of the wear plate and the surface of the wear plate and through the first recess in the upper surface of the bolster. A second, longer bolt extends through the lower hole and wear plate surface and through a second recess in the upper surface of the bolster. Both the first recess and the second recess are located at substantially the same height and allow fastening of the bolt with a corresponding nut or other connection of similar form. That is, because the lower bolt is connected in a second recess separate from the first recess, the corresponding connector can be tightened without having to pass through the small opening in the upper bolst...

Abstract

A rail car truck bolster wear plate surface connects to a wear plate using two fasteners of different length. The first fastener passes through an upper opening and an upper channel into a first recess where it can be tightened against a first engaging surface. The second fastener is longer than the first fastener and passes through a lower opening and lower channel into a second recess adjacent to the first recess. The surfaces of the first and second recesses form a series of ribs in the upper end surface between the wear plate surface and the longitudinal centerline of the bolster.

Description

[0001] related application [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 597,992, entitled "RAILCAR TRUCK BOLSTER," filed December 13, 2017, the entire contents of which are hereby incorporated by reference. technical field [0003] This application relates to railcar truck bolsters. More specifically, the present application relates to embodiments for attaching friction shoe wear plates to railcar truck bolsters. Background technique [0004] Railroad vehicles traditionally consist of a car body straddling on top of a chassis or frame called a bogie, which serves as a modular subassembly of wheels and axles. A conventional rail bogie comprises two side frames extending parallel to the direction of travel of the bogie. A pair of wheelsets spans between and supports each of the side frames at respective end locations. Each wheel set includes an axle extending generally perpendicular to the side frames and a pair of wheels at eac...
