Abstract

L'invention concerne un carter de moteur à combustion interne comprenant un carter chapeau et un insert (3, 31, 32) formant un palier pour un vilebrequin d'axe (L). Le carter chapeau est assemblé par moulage autour de l'insert (3, 31, 32). L'insert (3, 31, 32) est réalisé dans une matière différente du carter chapeau et comprend une structure de solidarisation (4) avec le carter chapeau (2). Selon l'invention, la structure de solidarisation (4) comprend au moins une protubérance (41, 42) s'étendant depuis un côté latéral de l'insert (3, 31, 32). La protubérance (41, 42) comporte une ouverture destinée à être remplie de matière constitutive du carter chapeau lors du moulage du carter chapeau autour de l'insert (3, 31, 32).The invention relates to an internal combustion engine housing comprising a bonnet housing and an insert (3, 31, 32) forming a bearing for an axis crankshaft (L). The cap housing is assembled by molding around the insert (3, 31, 32). The insert (3, 31, 32) is made of a material different from the cap casing and comprises a securing structure (4) with the cap casing (2). According to the invention, the securing structure (4) comprises at least one protuberance (41, 42) extending from a lateral side of the insert (3, 31, 32). The protuberance (41, 42) has an opening intended to be filled with material constituting the cap casing during the molding of the cap casing around the insert (3, 31, 32).
