An axle assembly for frame rail vehicles is described herein. The axle assembly also includes a drive unit housing that includes an interior cavity enclosing first and second electric machines, a common gear reduction, a differential gear set, and a speed change mechanism with the first and second axle shafts partially disposed within the interior cavity and extending out of the drive unit housing. The drive unit housing includes a central cavity, a lower cavity, a first machine cavity, and a second machine cavity. The central cavity includes the common gear reduction and the axis of rotation of the first and second axle shafts. The lower cavity accumulates a volume of gearbox fluid with the speed change mechanism at least partially immersed in the lower cavity. The first machine cavity includes the first electric machine and the second machine cavity includes the second electric machine.

A transmission subassembly for a working vehicle includes an engageable front wheel drive, a transmission housing, a clutch module, and a hydraulic module. The hydraulic module is received between the clutch module and the transmission housing.

A powertrain apparatus for an electric vehicle may include a motor connected to an input shaft, a planetary gear train, which is disposed to be coaxial with the motor and which includes a first rotation element, a second rotation element and a third rotation element, at least one of which is configured to receive power from the input shaft, a differential gear disposed to be coaxial with the motor and the planetary gear train, a first gear set connected to one rotation element of the planetary gear train, and a second gear set configured to receive power from the first gear set and transmit the power to the differential gear.

A powertrain apparatus for an electric vehicle may include a motor connected to an input shaft, a planetary gear train, which is disposed to be coaxial with the motor and which includes a first rotation element, a second rotation element and a third rotation element, at least one of which is configured to receive power from the input shaft, a differential gear disposed to be coaxial with the motor and the planetary gear train, a first gear set connected to one rotation element of the planetary gear train, and a second gear set configured to receive power from the first gear set and transmit the power to the differential gear.

A drive system includes a first drive train and a second drive train coupled by a differential assembly. Each drive train include a motor, an output gear, and a clutch assembly that engages and disengages the output gear from respective halfshafts. The differential assembly is configured to couple the first and second halfshafts, and connect/disconnect the first output gear and the first halfshaft. The differential assembly includes, for example, side gears, a spider gearset, and an actuator for engaging and disengaging the differential casing from the first output gear. A control system is configured to actuate actuators of clutch assemblies and/or a differential assembly to achieve one or more drive modes for each drive axis. The control system determines the first drive mode, controls the clutch assemblies and differential assemblies, and controls one or more motors. The drive modes include, for example, torque vectoring, fully locked, single motor, and neutral.

A military vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, and a driveline. The driveline includes a first driver including an engine, an energy storage system, an accessory drive coupled to the engine, a transmission coupled to at least one of the front axle or the rear axle, and a second driver coupled to the engine and the transmission. The accessory drive includes a plurality of accessories and a first motor. The first motor is electrically coupled to the energy storage system. The second driver includes a second motor electrically coupled to the energy storage system.

A counter gear mechanism includes: a fifth gear in mesh with a third gear; a sixth gear in mesh with a fourth gear; and a seventh gear in mesh with a differential input gear. The seventh gear is disposed between the fifth gear and the sixth gear in an axial direction. A switching mechanism is disposed between the third gear and the fourth gear in the axial direction. The switching mechanism makes switching among: a state in which the third gear is coupled to a second input member; a state in which the fourth gear is coupled to the second input member; and a state in which the third gear and the fourth gear are decoupled from the second input member. This structure is able to make an entirety of an apparatus compact in size in the axial direction when the apparatus includes the switching mechanism to change the speed ratio between the second input member, which is drivingly coupled to an internal combustion engine, and output members.
