Abstract

L'invention concerne un procédé de fabrication d'un tambour de frein bimétallique possédant une grande rigidité et léger, comprenant les étapes suivantes : (a) découpage d'une tôle d'acier; (b) poinçonnage; (c) repoussage consistant à repousser la périphérie du produit semi-fini obtenu dans l'étape précédente de manière à former une couronne extérieure cylindrique composée de couronnes saillantes; (d) repoussage-laminage consistant à repousser plusieurs évidements intérieurs répartis régulièrement sur la paroi interne des couronnes saillantes du produit semi-fini; (e) coulage consistant à couler la chemise en fonte dans le produit semi-fini par coulage par centrifugation; (f) traitement thermique consistant à éliminer la contrainte interne et à rendre la rigidité de la chemise en fonte conforme aux exigences s'appliquant au tambour de frein; (g) usinage de finition. Ce procédé présente les avantages suivants : la rigidité de la liaison entre la chemise en fonte et la coque en acier est supérieure et le moment de freinage peut être conduit directement entre ces derniers, au lieu d'utiliser des attaches telles que des rivets ou des boulons pour assembler la couronne extérieure du tambour de frein et la chemise, ce qui permet d'éviter le glissement entre la couronne extérieure et la chemise et de centraliser la contrainte.
