Abstract

L'invention porte sur un capuchon d'ensemble roulement de moyeu 200, configuré avec une structure pilote 202 définie par des parties annulaires radialement interne et radialement externe 202a, 202b reliées par un coude annulaire 202c disposé entre une face centrale 204 du capuchon et une bride périphérique externe 206. La structure pilote 202 se projette dans une direction axialement vers l'extérieur le long de l'axe X de l'ensemble roulement de moyeu 100 pour une adaptation à l'intérieur d'une surface de diamètre interne 112 d'un élément axial externe 106, pour faciliter l'étanchéité et une retenue sollicitée par ressort du capuchon 200 à l'intérieur de l'ensemble roulement de moyeu 100. La bride périphérique externe 206, qui est contiguë à la structure pilote 202, appuie contre une face d'extrémité intérieure 114 de l'élément axial externe 106 de l'ensemble roulement de moyeu 100 pour constituer une butée axiale positive, et est configurée pour constituer un élément d'étanchéité supplémentaire afin de réduire l'entrée de contaminant entre le capuchon 200 et les surfaces intérieures de l'ensemble roulement de moyeu 100.
