First claim
Opening claim text (preview).
1 . An axle assembly, comprising: a first axle shaft including a first conduit; a second axle shaft including a second conduit, the first conduit and the second conduit being in fluid communication through a chamber; and a differential operatively connected to the first axle shaft and the second axle shaft, wherein the chamber is at least partially disposed within the differential. 2 . The axle assembly of claim 1 , further comprising a first hub rotatably disposed on an axle housing and secured to the first axle shaft, the first hub comprising a hub conduit in fluid communication with the first conduit. 3 . The axle assembly of claim 1 , further comprising a seal assembly at least partially defining the chamber. 4 . The axle assembly of claim 1 , wherein the chamber is disposed entirely within the differential. 5 . The axle assembly of claim 1 , wherein the first conduit and the second conduit are aligned. 6 . The axle assembly of claim 1 , wherein the first conduit extends from the differential to a flanged end of the first axle shaft. 7 . The axle assembly of claim 1 , wherein the second conduit extends from the differential to a flanged end of the second axle shaft. 8 . The axle assembly of claim 1 , wherein the first conduit is concentric with the first axle shaft and the second conduit is concentric with the second axle shaft. 9 . The axle assembly of claim 1 , wherein the chamber is at least partially disposed between an inboard end of the first axle shaft and an inboard end of the second axle shaft. 10 . The axle assembly of claim 2 , further comprising a second hub rotatably disposed on the axle housing and secured to the second axle shaft. 11 . The axle assembly of claim 3 , wherein the seal assembly is in sealing contact with an inboard facing surface of the first axle shaft and with an inboard facing surface of the second axle shaft. 12 . The axle assembly of claim 3 , wherein the seal assembly is disposed radially out from an inboard end of the first conduit and radially out from an inboard end of the second conduit. 13 . The axle assembly of claim 3 , wherein the seal assembly comprises a wall portion that is concertinaed. 14 . The axle assembly of claim 3 , wherein the seal assembly comprises a wall portion and an annular sealing member attached to the wall portion. 15 . An axle assembly, comprising: a first hub rotatably disposed on an axle housing, the first hub comprising a hub conduit; a first axle shaft secured to the first hub, the first axle shaft comprising a first conduit in fluid communication with the hub conduit; a second axle shaft comprising a second conduit, the first conduit and the second conduit being in fluid communication through a chamber; and a differential operatively connected to the first axle shaft and the second axle shaft, wherein a seal assembly at least partially defines the chamber. 16 . The axle assembly of claim 16 , wherein the seal assembly is provided within the differential. 17 . The axle assembly of claim 16 , wherein the seal assembly is provided between the first axle shaft and the second axle shaft. 18 . A tire inflation system comprising the axle assembly of claim 1 .
