Abstract

Rotule (10) comprenant une bague intérieure (20) et une bague extérieure (30) d'axe longitudinal (A1), de largeur (L) et réalisée en matériau céramique, la bague intérieure (20) comprenant une surface extérieure (21) sphérique tronquée, la bague extérieure (30) comprenant une surface intérieure (32) concave et en regard de la surface extérieure (21) de la bague intérieure (20), ainsi qu'une surface extérieure (31) et deux parois latérales (33) reliant les surfaces intérieure (32) et extérieure (31), la bague extérieure (30) étant en outre symétrique par rapport à un plan médian (P) perpendiculaire à son axe longitudinal (A1). Au moins lorsque la rotule n'est soumise à aucune charge, il existe un espace libre entre la surface extérieure (21) de la bague intérieure (20) et la surface intérieure (32) de la bague extérieure (30), de sorte à définir une distance radiale (Y) entre un point de la surface intérieure (32) de la bague extérieure (30) et la surface extérieure (21) de la bague intérieure (20), ladite distance radiale (Y) étant mesurée suivant une direction perpendiculaire à l'axe longitudinal (A1) de la bague extérieure (30).
