    [008] As required, detailed embodiments of the present invention are described herein; however, it is to be understood that the described embodiments are merely exemplary of the invention, which may be embodied in diverse and alternative ways. Figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, the specific structural and functional details disclosed herein are not to be construed as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
    [009] Referring to Figure 1, a portion of an exemplary axle assembly 10 is shown. The axle assembly 10 may be provided with a motor vehicle, such as a truck, bus, agricultural equipment, military transport or transport vehicle. armament, or cargo equipment for transport by land, air or sea vessels or a trailer which may be supplied with a motor vehicle.
    [010] Shaft assembly 10 can be configured as a drive shaft that can receive torque from a power source, such as an internal combustion engine or an electric motor. Alternatively, shaft assembly 10 can be configured as a non-drive shaft in one or more modalities. Shaft assembly 10 may or may not be steerable. In a drive axle configuration, axle assembly 10 may include an axle housing 20, an axle shaft 22, a spindle 24, and a wheel end assembly 26.
    [011] The axle housing 20 can receive various components of the axle assembly 10. In addition, the axle housing 20 can facilitate the mounting of the axle assembly 10 in the vehicle. Shaft housing 20 may define a cavity that can receive at least a portion of shaft shaft 22.
    [012] The axle shaft 22 can provide torque to the wheel end assembly 26 to drive the vehicle. For example, axle shaft 22 may be connected at a first end to a component of the vehicle's traction system, such as a differential or input shaft, and may be coupled to wheel end assembly 26 at a second end. In at least one embodiment, axle shaft 22 may extend along, and may rotate about, axle 30. Alternatively, axle shaft 22 may be configured for use with an independent suspension system and may have multiple segments. of shaft and/or joints, such as constant speed joints, which may facilitate relative movement between the first end and the end assembly of the wheel 26. The shaft shaft 22 may include a shaft flange 32 disposed at a distal end . The axle flange 32 can facilitate mounting the wheel end assembly 26 to the axle shaft 22. In a non-drive axle configuration, the axle shaft 22 may be omitted.
    [013] Spindle 24 can be provided with, or can be fixedly positioned relative to axle assembly 10. Spindle 24 can generally extend along, but cannot rotate around axle 30. In an axle configuration. drive, spindle 24 may include a first spindle end surface 42, an interior surface 44, an exterior surface 46, and a bore 48. In a non-drive shaft configuration, the interior surface 44 and bore 48 may be omitted . Furthermore, in a steerable non-drive shaft configuration, the spindle 24 may be provided with, or may be fixedly positioned relative to a shaft bearing, rather than the shaft housing 20. The first end surface of the spindle 40 may be disposed in proximity to, or may engage with, the shaft housing 20. The second end surface of the spindle 42 may be disposed opposite the first end surface of the spindle 40 and may be located near the flange of the shaft 32. inner surface 44 may protrude between the first end surface of the spindle 40 and the second end surface of the spindle 42 and may at least partially define the hole 48 through which the shaft shaft 22 may extend. As such, spindle 24 can be moved away from spindle shaft 22 to allow spindle shaft 22 to rotate about axis 30. Outer surface 46 can be disposed opposite inner surface 44. Outer surface 46 of the spindle 24 can support one or more wheel bearings, which can rotatably support the wheel end assembly 26, as will be discussed in more detail below.
    [014] The wheel end assembly 26 may be rotatably coupled to the axle shaft 22. The wheel end assembly 26 may include a hub 50, a braking subsystem 52, a wheel 54, and a tire 56.
    [015] Hub 50 can be rotatably disposed on spindle 24. For example, one or more wheel bearings can be mounted on spindle 24 and can rotatably support hub 50. In Figure 1, a first wheel bearing 60 and a second wheel bearing 62 are provided in a cavity 64 which is located between the spindle 24 and the hub 50. The first wheel bearing 60 may be disposed onboard or further away from the second end surface of the spindle 42 than of the second wheel bearing 62. As such, hub 50 may be configured to rotate about shaft 30. In a drive shaft configuration, shaft flange 32 may be coupled to hub 50 with one or more fasteners 66 As such, hub 50 may rotate with shaft shaft 22. In a non-drive shaft configuration, hub 50 may not be coupled to shaft shaft 22 or flange of shaft 32.
    [016] The braking subsystem 52 can be adapted to slow down or inhibit the rotation of at least one associated wheel 54. For example, the braking subsystem 52 can be configured as a friction brake, such as a drum brake or a disc brake. In Figure 1, a portion of the braking subsystem 52 is shown with a drum brake configuration.

For the sake of clarity, the term "pressurized gas" may refer to a pressurized gas or a mixture of pressurized gas. Tire inflation system 80 can include a control system that can monitor and control the inflation of one or more tires 56, a pressurized gas source 82, and a gas supply subsystem 84.
    [019] The pressurized gas source 82 can be configured to feed or store a volume of a pressurized gas or pressurized gas mixture, such as air or nitrogen. For example, the pressurized gas source 82 may be a tank and/or a pump such as a compressor. Pressurized gas source 82 may be disposed on the vehicle and may provide a pressurized gas or pressurized gas mixture at a pressure that is greater than or equal to a desired inflation pressure of a tire 56. As such, pressurized gas source 82 can inflate a tire or maintain a desired tire pressure.
    [020] The gas supply subsystem 84 may fluidly connect the pressurized gas source 82 to the tire 56. The gas supply subsystem 84 may include one or more conduits, such as a hose, tube, duct, or their combinations. In Figure 1, a first conduit 90 and a second conduit 92 are shown. First conduit 90 may be fluidly connected to, and may receive pressurized gas from pressurized gas source 82. Second conduit 92 may supply pressurized gas to tire 56. In addition, one or more valves may be associated with , or be provided with, a conduit for enabling or disabling the flow of pressurized gas from pressurized gas source 82 to one or more tires 56. The routing of conduits between pressurized gas source 82 and a tire 56, which is shown in Figure 1, is exemplary and not intended to be limiting, as other conduit routing paths may be provided. The pressurized gas flow is represented by the arrows located near the ducts in Figure 1.
