Abstract

L'invention concerne un module porteur (1) conçu pour une distribution à arbre à cames en tête (OHC) d'un moteur à combustion interne, comprenant deux parois de support (2) espacées l'une de l'autre, se faisant face, et pouvant être liées à une culasse au niveau de leurs faces inférieures (3) et à un couvre-culasse du moteur à combustion interne au niveau de leurs faces supérieures (4), chaque paroi comportant respectivement au moins un trou principal (5) pour supporter l'extrémité d'un arbre à cames (6) en et respectivement au moins un trou secondaire (7) pour supporter l'extrémité d'un arbre de levier de commande de soupape (8, 9). Ledit module porteur (1) est similaire à une boîte et les parois de support (2) sont reliées par des parois transversales (10), et le module de support (1) est fabriqué au moyen d'une technique de découpe et de flexion à partir d'un flan de tôle en acier.
