摘要： A coupling for connecting an input shaft to an output shaft through a bi-directional overrunning clutch assembly. A portion of the input shaft is located within an internal cavity of the output shaft. The bi-directional roller clutch assembly selectively connects and disconnects the input and output shafts from one another. A drive plate is disposed about and attached to a portion of the input shaft so as to rotate in combination therewith. The drive plate is rotationally connected to a clutch housing of the clutch assembly such that rotation of the input shaft produces corresponding rotation of the clutch housing. A torsion spring is positioned within a spring retainer and engaged with at least one of either the spring retainer or the clutch housing. An engagement control assembly controls the engagement and disengagement of the clutch assembly and a coil housing mounted in the cover and a coil mounted in the coil housing, the coil is connected to a switch for controlling the supply of current to the coil. The coil having an active state for generating magnetic flux when power is sent to the coil, and an inactive state when no power is sent to the coil and no magnetic flux is generated. At least one armature plate is disposed about the output shaft and positioned near the coil.

摘要： A drive train for a four wheel drive vehicle including a front differential engaged with a front drive shaft and front axles through a front differential gear set. The front differential includes a front bi-directional overrunning clutch that controls transmission of torque transfer between the front drive shaft and the front axles. A rear differential is engaged with rear axles and the transmission through a rear differential gear set. The rear differential includes a rear bi-directional overrunning clutch that controls torque transfer between the transmission and the rear axles. The differentials are configured with a gear ratio that is within five percent of a 1 :1 gear ratio.

摘要： A positive drive differential assembly including a differential with an input pinion configured to operably engage with a drive shaft so as to permit the drive shaft to rotate the pinion. A bi-directional overrunning clutch assembly is configured to transmit torque between the pinion and two drive axle segments. A pinion disconnect assembly is provided for controlling transmission of rotation to the pinion and including a rotary coupler. A linear actuator is connected to the rotary coupler and configured to translate the rotary coupler between connected and disconnected positions.
