Embodiment Construction

[0023] Referring now to FIG. 1 , it can be seen that the lateral ends of each side frame 14 include downwardly extending pedestal jaws 22 . It can be seen that the inner wall 26 of the pedestal jaw opening 22 combines along a roof section 28 and vertical face 24 to form a pedestal jaw opening. At the interface between the vertical face 24 and the top region 28, an inner thrust lug 29 can be seen. It can be seen that the inner thrust protrusion 29 comprises an inclined region extending from an upper region of the vertical face 24 to an inward region of the top region 28 . Similarly, but not fully visible in the perspective view of FIG. 1 , the outer thrust protrusion 31 includes an inclined region extending from the upper part of the inner wall 26 to the interior of the top region 28 .

[0024] Another part of the invention includes a bearing adapter 30 which is a generally rectangular structure with depending struts extending therefrom. Bearing adapter 30 typically comprises...

Abstract

A bearing holder for the rolling stock with two side frames and supporting beams can be arranged in the opening of axle box at each terminal of each side frame, and is composed of a holder body made of cast steel and able to be installed to top of bearing unit, and a lining pad installed to the top of said holder body and with an elastic body having a chosen hardness and an extended part embedded in a notch on said holder body for higher stability.

Description

technical field [0001] This invention relates to railroad vehicles, and more particularly to support bearing nipples for use in the axle box cutouts of the side frames of railroad vehicles. Background technique [0002] In a railroad car, the two axles are held in a pair of laterally spaced side frames such that a corbel extends laterally between and bears on each side frame. The wheels are crimped onto the axle so that the end of the axle is also fitted with a rolling bearing arrangement. The rolling bearing arrangement fits itself into bearing sleeves which fit into the axle box cutout openings at the longitudinal ends of each side frame. The bolster ends themselves bear on a spring set which bears on the lower part of the central opening of the side frame. [0003] US Patent No. 5,562,045 discloses a nipple and spacer arrangement useful in fitting a bearing arrangement into the pedestal cutout opening of each side frame. The bearing adapter, which fits itself on top of...
