Abstract
A wear-resistant liner for center plate structure of a railway vehicle is provided and such liner is defined by an ultra high molecular weight polymeric material having metal reinforcing means embedded in and surrounded by the polymeric material which serves as a matrix for the reinforcing means and the metal reinforcing means comprises a metal structure having openings therein for receiving the polymeric material completely therethrough and enabling better embedment of the metal structure with the metal structure providing reinforcement and preventing cold flow of the polymeric material, and with the metal structure being a grid-like structure.
Claims17
In a wear-resistant liner for the center plate structure of a railway vehicle, said liner being defined by an ultra high molecular weight polymeric material, the improvement comprising metal reinforcing means embedded in and surrounded by said polymeric material which serves as a matrix for said reinforcing means, said metal reinforcing means comprising a metal structure having openings therein for receiving said polymeric material completely therethrough and enabling better embedment of said metal structure, said metal structure providing reinforcement and preventing cold flow of said polymeric material, and said metal structure being a grid-like structure.
In a railway vehicle having a body provided with a body bolster and a body center plate, and a truck provided with a truck bolster and a bolster bowl defined by a truck center plate having an upstanding peripheral flange, said body center plate being received within said flange and being supported by said truck center plate, and a wear-resistant liner disposed between said center plates, said liner being defined by an ultra high molecular weight polymeric material, the improvement comprising metal reinforcing means embedded in said polymeric material which serves as a matrix for and substantially completely surrounds said reinforcing means, said metal reinforcing means comprising a metal structure having openings therein for receiving said polymeric material completely therethrough and enabling better embedment of said metal structure, said metal structure providing reinforcement and preventing cold flow of said polymeric material, and said polymeric material being polyethylene.
In a railway car having a body provided with a body bolster and a body center plate, a truck provided with a truck bolster and a bolster bowl defined by a truck center plate having an upstanding peripheral flange, said body center plate being received within said flange and being supported by said truck center plate, said center plate and bolsters having cooperating vertically aligned openings, a center pin extending through said openings, and a wear-resistant liner disposed between said center plates, said liner being defined by an ultra high molecular weight polymeric material consisting of polyethylene, said liner having a central opening therein for receiving said pin therethrough, the improvement comprising metal reinforcing means embedded in said polymeric material which serves as a matrix for and substantially completely surrounds said reinforcing means, said metal reinforcing means comprising a metal structure having openings therein for receiving said polymeric material completely therethrough and enabling better embedment of said metal structure, said metal structure providing reinforcement and preventing cold flow of said polymeric material, and said liner comprising a flat disc-like portion and said central opening is disposed centrally therein and has a right circular cylindrical configuration.
