A power system for a vehicle comprising: a first engine, a second motor/generator, and a third motor/generator. The system further comprising: a first gearset with a first power train section coupled to an input side of the first gearset and a second power train section coupled to an output side of the first gearset. A mode selection device comprising at least two positions: a first position of the mode selection device coupling the third motor/generator to the first power train section, and a second position coupling third motor/generator to the second power train section. A clutch selectively connecting the first machine and the first power train section.

A differential system includes a differential and a differential disconnect mechanism. The differential includes an outer differential housing and an inner differential housing. The differential disconnect mechanism includes a disconnect clutch, first end face teeth and second end face teeth. The first end face teeth are disposed between the outer differential housing and the inner differential housing and are movably connected with the outer differential housing so that the first end face teeth can move axially and rotate synchronously relative to the outer differential housing. The second end face teeth are fixedly connected with the inner differential housing. The disconnect clutch is connected with the first end face teeth, and is configured to drive the first end face teeth to move axially relative to the second end face teeth.

Various systems and techniques for providing enhancements to bogie-equipped vehicles are described and discussed. Such systems and techniques include, for example, actively driven bogie differentials, elevated obstacle mounting techniques, worm-drive steering, parking modes using toe-in or toe-out wheel steering, speed-sensitive steering mode selection, and various other enhancements and techniques.

A transfer for a four wheel drive vehicle includes first and second distribution mechanisms that respectively include first and second clutches configured to be controlled to a half-engaged state. The first and second distribution mechanisms distribute a portion of power outputted from a power source to a second transmission mechanism respectively through the first and second clutches. A first difference is different from a second difference. The first difference is a difference between a gear ratio from an input shaft of the first clutch to a first driving wheel and a gear ratio from an output shaft of the first clutch to a second driving wheel. The second difference is a difference between a gear ratio from an input shaft of the second clutch to the first driving wheel and a gear ratio from an output shaft of the second clutch to the second driving wheel.

A tandem drive axle mechanical shift assembly including a first shift rail assembly having a first shift rail actuated via a first pneumatic actuator, and a shift fork having a first end coupled with the first shift rail and a second end coupled with an engagement selector. A second shift rail assembly having a second shift rail actuated via a second pneumatic actuator, and a second shift fork having a first end coupled with the second shift rail and a second end coupled with an inter-axle differential lock-up clutch. First and second primary valves in fluid communication with a reservoir, and a secondary valve in fluid communication with the reservoir and in selective fluid communication with the second pneumatic actuator. A first actuation valve operated by the first shift rail and in selective fluid communication with the first and second primary valves, and the first and second pneumatic actuators.

There is provided a work vehicle including a partition wall to keep partition between a first space zone as part of an internal space of the transmission case in which a differential mechanism is located and a second space zone as part of the internal space which is adjacent to the first space zone. An upper space is disposed above the partition wall and configured to allow lubricating oil scooped up from the first space zone by a ring gear to flow in the second space zone. A flow-out path is disposed below the upper space and configured to allow the lubricating oil to flow out of the second space zone to the first space zone.
