A land vehicle wheel end assembly (16) for a rigid tubular drive axle assembly (10) includes a nonrotatable sleeve (34) interposed between a portion of a spindle (14) of the axle assembly and a wheel hub (20). The wheel hub is rotatably supported on the spindle by inboard and outboard bearings (24,26) lubricated by oil from the drive axle. The hub includes a passage for directing the oil to the inboard bearing (24). The sleeve and hub include air passages (34f,34d,34e and 20e) for directing air from a vehicle onboard central tire inflation system to a pneumatic tire supported by the hub. A relative rotationalinterface between the sleeve and hub air passages is sealed by a seal assembly (52) which is lubricated by the oil. An outboard end of the sleeve preferably includes an axially open annular groove (45 or 47) for inserting an O-ring (38) seat therein after installation of the sleeve on the spindle.

Extrémité des roues (16) d'un véhicule terrestre pour un essieu moteur (10) tubulaire rigide comportant une gaine fixe (34) interposée entre une partie d'une fusée (14) de l'essieu moteur et un moyeu de roue (20). Le moyeu en question est soutenu de façon rotative sur la fusée au moyen de paliers intérieur et extérieur (24, 26) lubrifiés par l'huile provenant de l'essieu moteur. Il comprend un passage permettant de diriger l'huile jusqu'au palier intérieur (24). La gaine et le moyeu comportent des canaux d'air (34f, 34d, 34e et 20e) qui permettent de diriger l'air d'un système central de gonflage des pneus à bord du véhicule jusqu'à un pneumatique soutenu par le moyeu. Une interface rotative relative entre la gaine et les canaux d'air du moyeu est fermée au moyen d'une bague de graissage (52) lubrifiée par l'huile. De préférence, une extrémité extérieure de la gaine comprend une rainure annulaire ouverte en direction de l'axe (45 ou 47) permettant d'y insérer un siège de joint torique (38) une fois la gaine montée sur la fusée.
