Abstract

L'invention concerne un ensemble arbre à cames (1) pour modifier la position angulaire relative d'au moins une première came d'un arbre à cames (2) par rapport à une deuxième came de l'arbre à cames (2), l'ensemble comprenant un dispositif de réglage d'angle (3) qui présente un stator (4) et un rotor (5) disposé de façon à pouvoir tourner par rapport à ce stator, le rotor (5) étant relié de façon solidaire en rotation à un arbre (6), le stator (4) étant relié de façon solidaire en rotation à un arbre creux (7), l'arbre (6) et l'arbre creux (7) étant disposés de façon concentrique l'un par rapport à l'autre, la au moins une première came étant reliée de façon solidaire en rotation à l'arbre (6), la au moins une deuxième came étant reliée de façon solidaire en rotation à l'arbre creux (7) et la liaison solidaire en rotation entre le rotor (5) et l'arbre (6) étant obtenue au moyen d'au moins une vis (8). Afin d'établir une liaison fixe entre le rotor et l'arbre qui occupe moins d'espace, selon l'invention, l'arbre (6) repose par une face avant (9) sur une surface d'appui (10) du rotor (5) et est plaqué au moyen de la au moins une vis (8) contre la surface d'appui (10), l'arbre (6) présentant le long de son extension axiale, qui se trouve dans la zone du rotor (5), une surface de section transversale(A1) qui augmente jusqu'à la face avant (9) et adopte une valeur plus grande (A2).
