Abstract

L'invention se rapporte à un mécanisme de refroidissement pour un assemblage à roues volantes composé d'une première roue volante (12), d'une seconde roue volante (30) et d'une unité de plateau de fermeture d'embrayage (32), dans lequel des trous de refroidissement (52) sont ménagés dans la partie périphérique interne de la seconde roue volante (30) et des rainures de refroidissement sensiblement radiales (50), destinées à expulser par soufflage radial l'air contenu dans l'unité à plateau de fermeture d'embrayage (32) et émis par les trous de refroidissement (52), sont pratiquées à l'avant de la seconde roue volante (30). Des passages de circulation de l'air de refroidissement sont formés en prolongement des trous de refroidissement (52) et l'air de refroidissement atmosphérique est efficacement acheminé dans l'unité de plateau de fermeture d'embrayage (32), de façon à refroidir la surface de friction de la seconde roue volante (30). En outre, l'action de soufflage des rainures de refroidissement (50) sert à expulser activement dans l'atmosphère via les trous de refroidissement (52) l'air se trouvant dans l'unité de plateau de fermeture d'embrayage (32). Ainsi la pression régnant dans l'unité de plateau de fermeture d'embrayage (32) devient négative et assure un acheminement plus actif de l'air de refroidissement atmosphérique à l'intérieur de l'unité de plateau de fermeture d'embrayage (32).
