Abstract
A tapered wear liner and articulated connector using such a tapered wear liner are disclosed. The tapered wear liner supports an annular bearing that supports the male connecting member of the articulated connector. The tapered wear liner has an outer surface that may be shaped as the frustum of a cone or the frustum of a sphere. The female connecting member has a complementary shaped groove to receive the tapered wear liner. The female connecting member has a bottom wall with a substantially uniform thickness from the wear liner to the exterior surface of the female connecting member. A main pin connects the male and female connecting members together and a center pin is integral with the main pin and connected to the railroad car truck. The present invention is useful with railroad car trucks that have concave curved center plate areas.
