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.

Abstract: A power divider unit including an input shaft, a drive gear disposed around the input shaft, an inter-axle differential assembly coupled to the input shaft, an output side gear coupled to the input shaft, and a locking system for the power divider unit. The locking system is configured to passively lock the inter-axle differential assembly. The locking system includes a ramped first clutch member in selective engagement with the drive gear, a mating second clutch member configured to engage the first clutch member, a clutch pinion, and a slip clutch assembly. The second clutch member and the first clutch member rotate at different speeds, the clutch pinion rotates and causes the slip clutch assembly and second clutch member to rotate at a speed of the input shaft, causing the first clutch member to mate with the first clutch member.

Abstract: Methods and systems for an epicyclic gear mechanism that includes a primary differential assembly to selectively drive the fore secondary differential assembly and the aft secondary differential assembly. The fore secondary differential assembly selectively drives one or more fore interfaces (e.g., output gears), whereas the aft secondary differential assembly selectively drives one or more aft interfaces (e.g., output gears). Each of the primary differential assembly, the fore and aft secondary differential assemblies, and the interfaces rotate about a common central axis. The primary differential assembly drives the fore secondary differential assembly via a first sun gear, and drives the aft secondary differential assembly via a second sun gear, both of which rotate about the common central axis. Further, one or more actuators are to activate or deactivate in order to drive or be driven by a selected interface.

Abstract: A drive device includes a first clutch mechanism that couples or decouples power transmission systems for front and rear wheels, a first electric motor disposed on a front or rear wheel side and coupled to the first clutch mechanism, a second electric motor disposed on the other of the front and rear wheel sides and coupled to the first clutch mechanism, a second clutch mechanism that couples or decouples the first electric motor and front drive shafts, a planetary gear mechanism that distributes output of the first electric motor to the first and second clutch mechanisms, and a third clutch mechanism that limits a difference between a first rotational element that transmits the output of the first electric motor to the first clutch mechanism and a second rotational element that transmits the output of the first electric motor to the second clutch mechanism.

Abstract: A drive axle system having a one-way freewheel clutch. The one-way freewheel clutch is configured to transmit torque between first and second axle assembles when an interaxle differential unit is unlocked. The one-way freewheel clutch transmits torque to one of the first axle assembly and the second axle assembly when the interaxle differential unit is locked.
