Abstract:
1. A drivetrain comprising: an input shaft that is rotatable about a first axis, the input shaft being adapted to be driven by a powertrain having a prime mover with an output member that is rotatable about the first axis; a gear drive receiving rotary power from the input shaft, the gear drive having a gear drive output that is disposed about a second axis that is not coincident with the first axis; a front axle assembly with a front input pinion, a front ring gear and a front differential, the front input pinion being driven by the gear drive output about the second axis, the front ring gear being a bevel ring gear and being meshed with the front input pinion, the front differential receiving rotary power from the front ring gear; a propshaft assembly; a power switching mechanism with a power switching input, which is coupled to the input shaft for rotation therewith, and a power switching output, which is coupled to the propshaft for common rotation, the power switching mechanism being operable in a first switching mode, which inhibits transmission of rotary power between the power switching input and the power switching output , and a second switching mode that permits transmission of rotary power between the power switching input and the power switching output; a rear axle assembly having a rear axle input that is coupled to an end of the propshaft assembly opposite the power switching input; first and second shafts; and a torque transfer device (TTD) that is operable in a first TTD mode, in which transmission of rotary power between the rear axle input and at least one of the first and second shafts is inhibited, and a second TTD mode in which transmission of rotary power between the rear axle input and the at least one of the first and second shafts is permitted.
