Abstract
A vehicle drive train for transferring torque to first and second sets of wheels includes a first driveline adapted to transfer torque to the first set of wheels and a first power disconnection device. A second driveline is adapted to transfer torque to the second set of wheels and includes a second power disconnection device. A hypoid gearset is positioned within one of the first driveline and the second driveline in a power path between the first and second power disconnection devices. The hypoid gearset is selectively disconnected from being driven by either of the first driveline and the second driveline when the first and second power disconnection devices are operated in a disconnected, non-torque transferring, mode.
Claims20
A vehicle drive train for transferring torque to first and second sets of wheels, the drive train comprising:
- a first driveline being adapted to transfer torque to the first set of wheels and including a first power disconnection device;
- a second driveline being adapted to transfer torque to the second set of wheels and including a second power disconnection device;
- and
- a hypoid gearset positioned within one of the first driveline and the second driveline in a power path between the first and second power disconnection devices, wherein the hypoid gearset is selectively disconnected from being driven by either of the first driveline and the second driveline when the first and second power disconnection devices are operated in a disconnected, non-torque transferring, mode.
A vehicle drive train for transferring torque from a power source to first and second sets of wheels, the drive train comprising:
- a first driveline adapted to transfer torque from the power source to the first set of wheels and including a power take-off unit, the power take-off unit including a hypoid gearset and a first power disconnection device selectively ceasing the transfer of torque to the hypoid gearset;
- and
- a second driveline in receipt of torque from the hypoid gearset, the second driveline transferring torque to the second set of wheels and including a second power disconnection device selectively interrupting a transfer of torque from the second set of wheels to the hypoid gearset.
A vehicle drive train for transferring torque from a power source to a first pair and a second pair of wheels, the drive train comprising:
- a first power transmission device adapted to transfer torque from the power source to the first pair of wheels, the first power transmission device including a first hypoid gearset and a first power disconnection device selectively ceasing the transfer of torque to the first hypoid gearset;
- and
- a second power transmission device in receipt of torque from the first hypoid gearset, the second power transmission device transferring torque to the second pair of wheels and including a second hypoid gearset, a second power disconnection device selectively interrupting a transfer of torque from one of the second wheels to the second hypoid gearset, and a third power disconnection device selectively interrupting a transfer of torque from the other of the second wheels to the second hypoid gearset.
