Abstract: A tandem wheel assembly includes a tandem wheel housing having a center opening extending along a pivot axis, and wheel end openings extending along associated wheel axes. A pivot cage is configured to fixedly mount to a chassis of a vehicle and is disposed about the pivot axis at the center opening. A center sprocket is disposed within and rotatable with respect to the pivot cage. A wheel end assembly is disposed at each wheel end opening and has a wheel end sprocket, a wheel end gear train, and a wheel end hub. Each wheel end gear train is coupled for rotation by the wheel end sprocket and rotates the wheel end hub about the wheel end axis. A pair of reaction bars are pivotally coupled to the pivot cage at one end and to a component of the wheel end gear train at the other end.

Abstract: Methods of controlling a tandem axle assembly in a vehicle, the tandem axle assembly including an inter-axle differential (IAD), one or more side gears, and a front tandem axle assembly having a pair of front tandem axle half shafts selectively connected to a pair of front tandem axle wheel hub assemblies. When a determined speed of the vehicle is greater or equal to a predetermined speed, the IAD may be locked, the tandem axle wheel hub assemblies may be disconnected from their respective tandem axle shafts, and/or the IAD may be moved out of engagement with the one or more side gears. When a determined speed of the vehicle is less than a predetermined speed, the IAD may be unlocked, the tandem axle wheel hub assemblies may be connected to their respective tandem axle shafts, and/or the IAD may be engaged with the one or more side gears.
