An axle assembly that includes an axle housing, a differential carrier, and an electric motor module. The differential carrier that is mounted to the axle housing and rotatably supports a differential. The electric motor module is received inside the differential carrier and is operatively connected to and provides torque to the differential.

Axle assembly having an electric motor module

An axle assembly having a wheel end disconnect and a method of control. The axle assembly may include a friction clutch and a locking clutch that may be received in a hub assembly. The friction clutch may be moveable between an engaged position and a disengaged position. The locking clutch may be moveable between a locked position and an unlocked position and may actuate the friction clutch to the disengaged position.

A wheel end assembly includes a brake rotor that is rotatable about an axis and a tone ring that is secured to the brake rotor. The brake rotor includes a protrusion that extends into a brake rotor opening. The tone ring includes a recess that receives the protrusion to restrict rotational movement of the tone ring with respect to the brake rotor.

Brake rotor and tone ring assembly

An axle assembly having an axle housing, a differential carrier, an electric motor module, and a gear reduction module. The differential carrier may be mounted to the axle housing and may rotatably support a differential. The electric motor module may be disposed in the differential carrier. The gear reduction module may be disposed adjacent to a differential carrier cover and may transmit torque from the electric motor module to the differential via a drive pinion.

Axle assembly having an electric motor module and a gear reduction module

An axle assembly having an electric motor module, a gear reduction module, and a shift mechanism. The shift mechanism may have a shift collar that may transmit torque from the gear reduction module to a drive pinion. The shift collar may be movable between a first position in which a low range gear ratio is engaged, a second position in which a neutral gear ratio is selected, and a third position in which a high range gear ratio is engaged.

An axle shaft is fabricated from two separate pieces. The axle shaft is comprised of an axle shaft body having a forged initial flange portion formed at one end. An axle shaft flange, fabricated by stamping or casting for example, is secured to the forged initial flange portion at a weld interface to form a finished axle shaft.

Axle shaft assembly

A spindle includes an inner bearing shoulder to seat an inner bearing and an outer bearing shoulder to seat an outer bearing. The inner and outer bearing shoulders are spaced apart by a controlled distance such that the outboard bearing is accurately positioned relative to the inboard bearing to control endplay and preload without requiring bearing adjustment.

Spindle for controlling wheel end endplay and preload

An adjustment assembly includes first and second connection points associated with a component. The second connection point is selectively adjustable to adjust a position of the component. A shield has one end coupled to the first connection point and an opposite end proximate to the second connection point to selectively prevent access to the second connection point. The shield is selectively movable when the first connection point is loosened to allow access to the second connection point. To achieve proper adjustment of the component, the first connection point must be loosened prior to adjusting a position of the second connection point.

Adjustment assembly

An axle assembly includes a non-rotating component and a wheel hub supported for rotation relative to the non-rotating component about an axis. The wheel hub includes a hub air passage that has a hub inlet and a hub outlet to be fluidly connected to at least one tire. An air chamber is formed at least in part between the non-rotating component and the wheel hub. The air chamber receives air flow from an air source and directs air flow into the hub inlet. A seal assembly engages the wheel hub to seal the air chamber.

Tire inflation system with integrated wheel seal

A wheel hub includes a hub flange that extends about the wheel hub. The hub flange includes a removed section that is aligned with a camshaft assembly. An insert is used to fill the removed section. The insert is selectively removable from the hub flange to provide access to the removed section such that the camshaft assembly can be removed from a brake assembly via the removed section without having to remove the wheel hub from an axle assembly.

Wheel hub for camshaft serviceability

A drive axle assembly includes a non-rotating spindle having a cylindrical body defining an internal cavity and an axle shaft assembly mounted within the internal cavity for rotation about an axis. A seal assembly is positioned within the internal cavity to provide a sealed chamber between the axle shaft assembly and the non-rotating spindle. A first air passage is formed within the cylindrical body and includes an air inlet to be in fluid communication with an air supply and an air outlet in fluid communication with the sealed chamber. A second air passage is formed within the axle shaft assembly and receives air input from the sealed chamber and includes an air output to be associated with at least one tire.

A wheel assembly includes a wheel hub and brake rotor that rotate about an axis. The brake rotor includes an outer circumferential surface area that cooperates with brake pads to provide braking for the wheel assembly. The brake rotor includes an inner circumferential surface area that has two different sets of mounting bosses. A first set of mounting bosses is spaced circumferentially about the axis and provides a mounting interface for a tone ring as used in an anti-lock brake system. A second set of mounting bosses is also spaced circumferentially about the axis but does not overlap the first set of mounting bosses. The second set of mounting bosses provides a mounting interface for securing a brake rotor and tone ring assembly to the wheel hub.

A vehicle wheel assembly includes a hub adaptor that eliminates the need for a separate hub cap and gasket by providing wheel rim, wheel hub, and brake component attachment interfaces, as well as a lubrication chamber that can be visually inspected to monitor lubrication levels. The hub adaptor comprises a single piece body having an outwardly extending mounting flange with a first plurality of apertures that define a wheel rim attachment interface. The hub adaptor also includes an inner recessed area with a second plurality of apertures that define both the wheel hub and brake component attachment interfaces. The hub adaptor also includes an inner circumferential surface that provides a piloting and sealing interface between the hub adaptor and the wheel hub.
