Abstract: An axle system is provided herein. In one example, the axle system includes a gearbox housing at least partially enclosing a gearbox and a planetary gearset that is rotationally coupled to an output of the gearbox and positioned co-axial with a rotational axis of an axle shaft in a differential. The planetary gearset includes a ring gear grounded by a planetary support that is attached to the gearbox housing.

Abstract: Various methods and systems are provided for a drive arrangement for a vehicle including a housing, a double planetary gear set partially or fully contained within the housing, an input shaft selectively engaged with the double planetary gear set, a first clutch assembly coupled to the input shaft and selectively engaged with the double planetary gear set, a second clutch assembly coupled to the input shaft and selectively engaged with the double planetary gear set, and a sliding spline coupled to the input shaft and selectively engaged with the double planetary gear set. The double planetary gear set including a first sun gear, a second sun gear, a first set of planetary gears, a second set of planetary gears, a planetary gear carrier, and a ring gear, wherein components of the double planetary gear set are lockable thereby providing three different gear ratios.

Abstract: Methods and systems are provided for controlling a multi-axle assembly in a vehicle. The multi-axle assembly may be operated according to a requested mode, where the mode includes providing torque at one, two, or no axles of the multi-axle assembly, and the requested mode may be selected based on vehicle speed. In this way, operation of the multi-axle assembly may be adjusted according to a fuel efficiency of the vehicle while the vehicle is in motion.

Abstract: Various methods and systems are provided for a multi-speed electric axle assembly with three gear ratios. The multi-speed electric axle assembly includes one or more power supplies, one or more shafts operatively coupled to the one or more power supplies and a differential, and one or more Ravigneaux gear assemblies integrated with the one or more shafts. The one or more Ravigneaux gear assemblies of the multi-speed electric axle assembly providing the three gear ratios.
