  • All wheel drive system
    Patent number: 8434582
    Abstract: A drive system and an interconnection unit are provided for an all wheel drive vehicle. The drive system includes, but is not limited to a power take-off unit, a propshaft and a rear drive module. The power take-off unit being adapted to be attached to a vehicle's powertrain, and the propshaft being adapted to transmit drive to the rear drive module. The propshaft and the power take-off unit are connected by a joint for transmitting drive force from the power take-off unit to the propshaft, and the joint between the power take-off unit and the propshaft includes, but is not limited to a female-male engagement. The female and male engagement portions are non-rotatable in relation to each other when the joint is engaged.
