A vehicle with a primary driveline that is configured to distribute rotary power to a first set of vehicle wheels and a power transmitting device that can be selectively operated to transmit rotary power to a secondary driveline. The power transmitting device has an input member, which is driven by the primary driveline, and an output member that is selectively coupled to the input member to receive rotary power therefrom. The secondary driveline comprises a differential, a pair of shafts, and a side shaft coupling that selectively interrupts power transmission between the differential and one of the shafts.

Motor vehicle with disconnectable all-wheel drive system

A method of operating a multi-mode drive system that precisely orchestrates a shift between gear ratios in a power take off unit and a rear drive module. The method first shifts between gear ratios in the power take off unit and then, depending upon the success or failure of the shift of the power take off unit, shifts between gear ratios in the rear drive module.

Control strategies for a multi-mode drive system

A vehicle with a primary driveline that is configured to distribute rotary power to a first set of vehicle wheels and a power transmitting device that can be selectively operated to transmit rotary power to a secondary driveline.

A vehicle with a primary driveline that is configured to distribute rotary power to a first set of vehicle wheels, a power transmitting device and a secondary driveline that is configured to distribute power to a second set of vehicle wheels. The power transmitting device has an input member, which is driven by the primary driveline, and an output member that is selectively coupled to the input member to receive rotary power therefrom. The secondary driveline has a propshaft, an axle input, a pair of axle shafts and at least one torque transfer device. The propshaft transmits rotary power between the output member of the power transmitting device and the axle input. The axle shafts are rotatably coupled to an output of the differential and configured to transmit rotary power to the second set of vehicle wheels. The at least one torque transfer device is configured to selectively inhibit torque transmission between the axle input and the second set of vehicle wheels.

An automotive differential has two annular housing parts that are screwed together and an adjustment collar that is screwed into one of the annular housing parts. A ring gear is supported by bearings in the respective housing parts for rotation on a longitudinal axis that is perpendicular to a plane through the juncture of the two annular housing parts. A pinion gear is also rotatably mounted in the annular housing part that carries the adjustment collar for rotation on an axis that is not parallel to the longitudinal axis of the ring gear. The pinion gear meshes with the ring gear. Gear backlash and bearing preload are adjusted by indexing the two housing parts with respect to each other and by positioning the adjustment collar with respect to the one housing part.
