Abstract

Un bogie de wagon comprend ceci : un traversin présentant une section dextrémité extérieure dotée de premiers et deuxièmes logements de sabot; un cadre latéral comprenant une ouverture de traversin définie par une paire de colonnes de cadre latéral; un élément de compression; et un siège à ressort. La taille de louverture de traversin permet daccueillir la section dextrémité extérieure du traversin. Un groupe de ressorts est positionné entre la section dextrémité extérieure du siège à ressort du traversin et le siège à ressort pour relier de manière résiliente le traversin au cadre latéral. De plus, des première et deuxième cales de friction comprennent chacune ceci : une face de colonne présentant des extrémités chanfreinées assurant une transition douce entre la face de colonne et les côtés adjacents de la cale de friction; une face en pente; un côté inférieur; et un témoin dusure sur un côté de la cale de friction. En outre, des première et deuxième plaques dusure sont positionnées entre les faces de colonne respectives des cales de friction et les colonnes de cadre latéral respectives. Des premier et deuxième inserts de cales sont chacun positionnés entre les faces en pente respectives des cales de friction et les logements de sabot respectifs. Le brut de coulée de la face de colonne, sans aucune autre finition, de chacune des cales de friction est essentiellement plat et présente un fini de surface inférieur à 500 micro-pouces RMS. Chaque cale de friction présente une microstructure en fer gris aciculaire qui comprend de la bainite, de la martensite, de lausténite, du carbure et pas plus denviron 5 % de perlite. Chaque cale de friction présente une dureté allant de 420 à 520 dureté Brinell.
