Problems solved by technology

However, one potential problem associated with this type of liner is that: due to the uneven installation of the center plate in the bowl, the accumulation of grease and dirt, and the irregular surface of the center plate and bowl, the There will be a lack of electrical conductivity between the bolster bowls
In addition, since these liners are commercially made from ultra-high molecular weight polyethylene (UHMWPE), it is possible that these liners are susceptible to cold flow under the weight of the transport vehicle supported by the center panel of the body.
Currently, there are no known solutions to these problems

Embodiment Construction

[0024] Referring now to the accompanying drawings, especially accompanying drawing 1, a kind of conventional railway car underframe 10 comprises conventional body bolster 12, is positioned on the conventional truck bolster 14 of vehicle truck 16, and can rotate or is rotatably connected to the truck bolster 14 . The bogie 16 includes wheels 18 (shown in phantom) mounted on axles 19 . The wheels are suitable for standard type railway tracks (not shown). A truck 16 is connected to the truck bolster 14 and also includes sideframes, which have been omitted from the drawing for clarity.

[0025] A conventional center plate assembly 22 is placed between the truck bolster and the body bolster. As shown in more detail in FIG. 4, the center plate assembly 22 includes a truck bolster bowl 24 and a car body center plate 34, wherein the truck bolster bowl 24 is matingly connected to the truck bolster 14 (see accompanying drawing 1), or integrally formed with the bogie bolster 14, and t...

Abstract

A self-lubricating center plate assembly liner for interposition between a carbody center plate and a truck bolster bowl in a center plate assembly on a railroad vehicle, wherein the liner is disposed substantially matches the center plate and includes a body with a glass-filled urethane load-carrying portion, and a plurality of carbon-filled urethane, compressible, resilient conductive elements extending through the load-bearing portion above and below to provide electrical communication between the plates and bowl of the center plate assembly.

Description

technical field [0001] The present invention relates to an electrically conductive center panel assembly liner for use on a railroad vehicle, and more particularly, to an electrically conductive center panel assembly liner for placement on carbody center panels and truck bearings on a railroad vehicle. beam bowl, wherein the liner includes a wear-resistant load bearing portion, and a plurality of compressible resilient conductive elements, wherein the conductive elements are between the body center plate and the truck bolster bowl of the center plate assembly Provides electrical conduction between the bodies. Background technique [0002] Conventional type rail transport vehicles are generally constructed with a main body comprising an undercarriage with a pair of spaced apart center panels. The center plate is located on a pair of spaced apart trucks and is rotatably or rotatably connected to the trucks. Bogies support vehicles in a rolling fashion along conventional rail...
