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 bi-directional overrunning clutch assembly for engaging secondary driven shafts in a four wheel drive vehicle. The assembly includes a differential housing with a pinion input gear rotatably disposed within it that is engaged to a drive shaft. A bi-directional overrunning clutch housing is engaged to the pinion gear. A roll cage assembly is located inside the clutch housing. A pair of hubs are positioned within the roll cage assembly and connected to the secondary driven shafts. An electromagnetic system controls indexes the roll cage in a first direction relative to the clutch housing a first indexing device for coupling the secondary drive shaft to the secondary driven axles when four wheel drive is needed, and in an opposite direction using a second indexing device when an engine braking condition is needed. A spring assembly is preferably used to bias the roll cage back to a neutral position.

摘要： An on-demand four-wheel drive system includes a differential for the rear axle, a differential for the front axle, and a center differential connecting to the front and rear axle differentials. All three of the differentials contain a bi-directional overrunning roller clutch to enable locking of their respective outputs. The clutches provide a superior on-demand four-wheel drive system that distributes power to each drive wheel to propel the vehicle.

摘要： A bi-directional overrunning clutch includes a housing and a pair of hubs substantially coaxially aligned within the housing. A pair of roll cages position a plurality of rollers between each hub and an inner cam surface of the housing. The rollers are positioned to wedge between the hub and the inner cam surface when one of the hub and the housing is rotated with respect to the other. End caps are attached to the housing adjacent to the hubs. A friction disk mechanism includes a friction plate rotating in combination with each the roll cage and a spring compressed between the end cap and the roll cage for biasing the friction member into frictional contact with the hub. An intermittent coupler is located between each roll cage and configured to engage the roll cages so as to permit indexing of one roll cage relative to the other.

摘要： A bi-directional overrunning clutch differential is configured to transmit power from an input shaft to a first output shaft and a second output shaft in a vehicle. The differential includes a differential housing having a first bearing seat and a second bearing seat. A first bearing is carried by the differential housing in the first bearing seat, and a second bearing is carried by the differential housing in the second bearing seat. A first retaining ring secures the first bearing in the first bearing seat, and a second retaining ring secures the second bearing in the second bearing seat. A first output hub is carried by the first bearing for rotation relative to the differential housing, and a second output hub is carried by the second bearing for rotation relative to the differential housing.
