An axle assembly including a disconnect assembly and an integrated fluid flow system. The disconnect assembly including an axially movable clutch member in selective engagement with at least one shaft to permit a rotation thereof. The fluid flow system includes a fluid flow member and a plurality of fluid passageways to permit a flow of a fluid (e.g. a lubricant) from a fluid source (e.g. a fluid sump of the axle assembly) to various components disposed within a carrier housing of the axle assembly and a return of the fluid back to the fluid source.

Axle assembly

A hierarchical control system for a tandem axle assembly for a vehicle is provided. The hierarchical control system includes a vehicle level controller, an actuator, a shift controller, and a sensor. The shift controller is capable of placing the tandem axle assembly in at least a first operating condition and a second operating condition using the actuator. In response to the sensor and an operating condition of at least one of the power source and the transmission of the vehicle, the shift controller adjusts a manner of placing the tandem axle assembly in at least one of the first operating condition and the second operating condition. The hierarchical control system facilitates performing a shifting procedure in an automatic manner or as desired by an operator of the vehicle without excessively increasing a cost and a complexity of the tandem axle assembly.
