A vehicle axle assembly (10) is proposed, comprising a hub (12), which is mounted on a cylindrical axle body (14) so that it can rotate about a central longitudinal axis (A), and an axially inner and an axially outer shaft sealing ring (36, 38) for indirect or direct sealing between the axle body (14) and the hub (12). In order to enable an autonomous feed of pressure medium into a vehicle tire, the vehicle axle assembly (10) is characterized by an annular chamber (34) that is formed between the two shaft sealing rings (36, 38), the axle body (14) and the hub (12), a first pressure medium line (28,) that extends through the axle body (14) or one of the two shaft sealing rings (36, 38) and opens out into the annular chamber (34), and a second pressure medium line (40) that extends out of the annular chamber (34) through the hub (12) and is designed to be connected to a wheel that is secured on the hub (12).

    L'invention concerne un ensemble essieu (10) de véhicule, comprenant un moyeu (12) monté rotatif autour d'un axe longitudinal central (A) sur un corps de pont (14) cylindrique, et un joint d'étanchéité d'arbre (36) interne axial et un joint d'étanchéité externe axial (38) pour l'étanchéité indirecte ou directe entre le corps de pont (14) et le moyeu (12). Pour obtenir une alimentation autonome d'un pneumatique de véhicule en agent de pression, l'ensemble essieu de véhicule (10) est caractérisé en ce qu'une chambre (34) annulaire est formée entre les deux joints d'étanchéité d'arbre (36, 38), le corps de pont (14) et le moyeu (12), en ce qu'une première conduite (28) d'agent de pression, qui s'étend à travers le corps de pont (14) ou un des deux joints d'étanchéité d'arbre (36, 38), aboutit dans la chambre annulaire (34), et en ce qu'une deuxième conduite (40) d'agent de pression s'étendant à partir de la chambre annulaire (34) traverse le moyeu (12) et est équipée d'une roue fixée au moyeu (12) aux fins de liaison.
