  • a noteworthy advantage of the invention is the possibility of a kit formation. Over a combination of comparatively few groups of differently dimensioned supporting walls with comparatively few groups of differently dimensioned base plates, a large number of different carrier modules can be presented. It is conceivable, for example, also the combination of a standard base plate with different sized or differently spaced support walls or a combination of standard support walls with different sized base plates, etc.

Abstract

L'invention concerne un module de support (1) pour une commande de soupapes à arbre à cames en tête (OHC) d'un moteur à combustion interne, comprenant deux parois de support (2) verticales et séparées qui peuvent être reliées au moins indirectement à un couvre-culasse par leur face supérieure (3) et au moins indirectement à une culasse par leur face inférieure (4), et qui comportent chacune au moins un trou principal et un trou secondaire (5, 6) pour loger un arbre à cames et un arbre de levier d'actionnement des soupapes (7, 8, 9). Au niveau de la face inférieure (4) de chaque paroi de support (2) part une branche (10) coudée à angle droit, qui est fixée sur une plaque de base (11) séparée servant à relier directement le module support (1) à la culasse. La plaque de base (11) et les parois latérales (2) et leurs branches (10) sont produites par une technique d'estampage-cintrage d'une tôle d'acier.
