A wheel end assembly for a tire pressure management system including an axle having an axle end portion and a rotary joint assembly disposed outboard of the axle end portion. The rotary joint has a rotary hub, a non-rotating tube spindle at least partially disposed within the rotary hub, the tube spindle having a tube spindle hollow central chamber, an air seal provided between the rotary hub and the tube spindle, and a bearing assembly provided between the rotary hub and the tube spindle. The bearing assembly is positioned outboard of the air seal.

Wheel end assembly with external rotary joint and rotary joint venting mechanism

A wheel end assembly for a tire inflation system includes a sealing ring disposed on an axle housing. The sealing ring includes a conduit formed therethrough in fluid communication with a conduit formed through a hub. The hub is rotatably disposed on the axle housing adjacent the sealing ring. An inner rotary seal is disposed between the sealing ring and the hub. An outer rotary seal is disposed between the sealing ring and the hub. The hub conduit is in fluid communication with the sealing ring conduit via an area between the inner rotary seal and the outer rotary seal. A bearing seal is disposed between the sealing ring and the hub. The bearing seal is disposed outboard of the outer rotary seal. The inner rotary seal, the outer rotary seal, and the bearing seal are each in sealing contact with the sealing ring.

Wheel end assembly for a tire inflation system and the tire inflation system made therewith

A hub assembly for a tire inflation system includes a hub configured to hold a wheel assembly. The hub has a hub conduit formed therethrough. The hub conduit has an inlet formed in an inner surface of the hub and an outlet formed adjacent an outboard end of the hub. A vent is formed in the hub. The vent includes one or more vent conduits which extend from the inner surface to an outer surface of the hub.

Hub assembly for a tire inflation system

An axle assembly includes an axle housing having a main body and defining an internal cavity. The axle housing includes a first and second opening defined in the main body and adapted to support a first and second differential bearing respectively. A differential assembly is supported in the axle housing with the first and second differential bearings. The main body defines an inner mounting surface, an outer face and an inner circumferential surface extending between the inner mounting surface and the outer face. The inner circumferential surface defines a third opening. The main body defines a relief formed through the inner mounting surface and extending through a portion of the inner circumferential surface. The relief defines a fluid communication path for delivering fluid to a pinion bearing assembly arranged in the third opening.
