Abstract

Una pieza fundida de rotula de enganche que tiene un area superficial de cojinete mejorada y la cual se utiliza en un enganche de vagon de carga ferroviario. La pieza fundida de rotula de enganche incluye una seccion de cola, y una seccion de nucleo. La seccion de nucleo tiene un agujero muy pequeno de pivote formado en la misma. Tal agujero muy pequeno de pivote tiene paredes laterales cilindricas generalmente rectas. Se conecta una seccion de cara frontal a la seccion de nucleo. Tal seccion de cara frontal incluye una seccion de nariz y una porcion de cara de traccion formada hacia adentro desde tal seccion de nariz. En al menos tal porcion de tal porcion de cara frontal y tal seccion de nariz se incluye un area superficial de cojinete mejorada la cual incluye una porcion substancialmente plana colocada substancialmente en una direccion vertical y que se encuentra substancialmente arqueada en una direccion horizontal. La porcion substancialmente plana se extiende durante una distancia predeterminada en la direccion vertical y durante una tramo predeterminado a lo largo de la direccion horizontal. Existe una seccion de transicion que une la seccion de cola con la seccion de nucleo. Tal seccion de transicion incluye una seccion metalica superior y una seccion metalica inferior que se extienden una hacia otra.
