A rotary wheel-end assembly (90) is provided that includes a disc-like member (26) that when secured to a vehicular wheel hub (16) is operative to rotate relative a stationary axle spindle as well as provide a first chamber (28) about the end of axle (2). Assembly (90) has a passageway (36) therethrough for conveying pressurized air to the tire from axle (2) and includes a cover (42) secured in spaced-apart relationship to a side of member (26) facing away from axle (2) to provide a second chamber (46). Chambers (28) and (46) are adapted to hold a lubricant for lubricating frictional interaction between rotary assembly (90) and stationary axle (2) as well as wheel bearings (12) and at least one opening (40) is provided through member (26) for providing fluid communication between chambers (28) and (46) in addition to the preferable inclusion of at least one resilient closable member (48) through cover (42) for conveying lubricant into chamber (46).
Unité rotative (90) fixée sur l'extrémité d'une roue et munie d'un élément (26) en forme de disque qui, lorsqu'il est fixé au moyeu (16) de la roue d'un véhicule, est en mesure de tourner autour de la fusée de l'essieu en fournissant un premier logement (28) entourant l'extrémité de l'essieu (2). Cet ensemble (90) comporte un passage (36) entre l'essieu (2) et le pneu qui est traversé par de l'air pressurisé, et il comprend un couvercle (42) assujetti (sans lui être directement contigu) à un côté de l'élément (26) orienté dans le sens opposé à l'essieu (2), lequel forme un deuxième logement (46). Les logements (28) et (46) sont conçus pour contenir un lubrifiant qui permet une interaction par friction entre l'ensemble rotatif (90) et l'essieu fixe (2) de même qu'entre les roulements (12) de roue, une ouverture (40) au moins étant formée dans l'élément (26) pour permettre au liquide de circuler entre les logements (28) et (46). Ces derniers comportent de préférence au moins un élément souple refermable traversant le couvercle (42) pour introduire le lubrifiant dans le logement (46).
