A method for operating an electric vehicle for traversing off-road terrain includes operating the vehicle both in a normal operating mode and an electric low range operating mode. A control unit receives inputs from sensors that determine vehicle operating conditions, such as vehicle speed, grade of terrain, accelerator position, and brake pedal position. The method adjusts motor torque or the maximum allowable motor as a function of the determined vehicle operating conditions, to provide improved electric vehicle operation in a low range mode, including the increasing motor torque at different rates relative to the normal mode, allowing a greater maximum allowable torque, increasing torque to overcome obstacles, and increasing torque to ascend or descend.

SHIFT ISOLATION LEVER SYSTEM FOR POWER-ACTUATED COUPLING DEVICE
A clutch assembly incorporated into a power transfer assembly (72) of a motor vehicle is presented. The clutch assembly includes a power-operated clutch actuator (306) for moving a clutch sleeve (354) axially between released and engaged positions between two rotatory members. In the released position, relative rotation between two rotary members is prevented. Whereas in the engaged position, relative rotation is permitted. The power-operated clutch actuator (306) further includes an electromagnetic solenoid with an output member having an extended condition and a retracted condition urging the clutch sleeve (354) between positions. A shift isolation linkage mechanism (304) interconnects the output member of the solenoid to the clutch sleeve (354) and permits movement of the output member to its retracted position while a blocked tooth condition inhibits movement of the clutch sleeve (354) to its engaged position. Once the blocked tooth condition is removed, the isolation linkage mechanism (304) forces the clutch sleeve (354) to its engaged position.
A pumpless lubrication system for a power transfer assembly equipped with a hypoid gearset having a ring gear and a hollow pinion unit. Lubricant splashed from one of the ring gear and the pinion unit is collected in a collection reservoir and directed through a conduit unit into the hollow pinion unit.

A vehicle powertrain system and powertrain actuator therefor is provided. The powertrain actuator selectively couples a first rotatable member to a second rotatable member to transfer torque therebetween and selectively decouples the first rotatable member from the second rotatable member to prevent the transfer of torque therebetween. The powertrain actuator includes a tubular cam assembly having a tubular first member and a tubular second member. The tubular first and second tubular members have end surfaces that interact with one another upon energizing a unidirectional solenoid. Upon a first energization of the solenoid, the first and second tubular members interact to operably couple the first and second rotatable members to allow torque to be transferred therebetween, and upon a second energization of the solenoid, the first and second tubular members interact to selectively decouple the first the second rotatable members to prevent the transfer of torque therebetween.

A power transmission device for a four-wheel drive vehicle includes an input shaft adapted to be driven by a power source. A first output shaft is rotatable about a first axis and adapted to transmit torque to a first driveline. A second output shaft is adapted to transmit torque to a second driveline and is rotatable about a second axis. The first and second axes diverge from one another. A transfer unit includes a drive member rotatably supported on the first output shaft and a driven member coupled to the second output shaft. A joint is positioned within a cavity formed in the driven member and drivingly interconnects the driven member and the second output shaft. The driven member includes first and second portions separable from and re-mountable to each other to allow service to the joint.
A power transmission device for a four-wheel drive vehicle having a power source and first and second drivelines includes an input shaft adapted to be driven by the power source. A first output shaft is rotatable about a first axis and adapted to transmit torque to the first driveline. A second output shaft is adapted to transmit torque to the second driveline and is rotatable about a second axis. The first and second axes do not extend parallel to each other. A transfer unit includes a first cylindrically-shaped gear rotatably supported on the first output shaft and a second conically-shaped gear fixed for rotation with the second output shaft. The first and second gears are in constant meshed engagement with each other.
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 the first driveline and the second driveline when the first and second power disconnection devices are operated in a disconnected, non-torque transferring, mode. At least one of the first and second power disconnection devices includes an active dry friction clutch.
A method of controlling a drive train of a vehicle includes collecting acceleration data from the vehicle as vehicle tires travel across a road surface. The data is analyzed to determine a condition of the road surface. The drive train is preemptively switched from a two-wheel drive mode to a four-wheel drive mode prior to a wheel slip based on the analysis of the data.
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 synchronizing clutch. A second driveline is adapted to transfer torque to the second set of wheels and includes a power disconnection device and a friction clutch. A hypoid gearset is positioned within the second driveline in a power path between the synchronizing clutch and the power disconnection device. The friction clutch and the power disconnection device are positioned on opposite sides of the hypoid gearset. The hypoid gearset is selectively disconnected from being driven by the first driveline, the second driveline or the wheels when the synchronizing clutch and the power disconnection device are operated in disconnected, non-torque transferring, modes.
