摘要： A drive axle assembly includes first and second axleshafts connected to a pair of wheels and a drive mechanism operable to selectively couple a driven input shaft to one or both of the axleshafts. The drive mechanism includes a differential, a speed changing unit operably disposed between the differential assembly and the first and second axleshafts, first and second mode clutches and a brake unit. The first mode clutch is operable to increase the rotary speed of the first axleshaft which, in turn, causes a corresponding decrease in the rotary speed of the second axleshaft. The second mode clutch is operable to increase the rotary speed of the second axleshaft so as to cause a decrease in the rotary speed of the first axleshaft. The brake unit is operable to engage the speed changing unit. A control system controls actuation of both mode clutches.

摘要： A driveline component with a first drive member, which is rotatable about an axis, a second drive member and a clutch. The second drive member has a hub, which is supported on the first drive member for rotation about the axis, and a transmission portion. The transmission portion, which is configured to engage a flexible power transmitting member, is disposed about the hub and aligned to a transmission axis that is generally perpendicular to the axis. The clutch has a spring and a set of interleaved clutch plates having portions that are coupled for rotation with a respective one of the first drive member and the second drive member. The spring generates a force that is transmitted through the hub such that the clutch plates frictionally engage one another. The location of the transmission portion relative to the transmission axis is unaffected by wearing of the set of clutch plates.

摘要： A transfer case for a motor vehicle having an input shaft, a first output shaft, a second output shaft, a clutch, a transfer mechanism, a sensor portion and a magnetoelastic torque sensor. The clutch has a clutch pack and a thrust mechanism that is configured to exert an engagement force on the clutch pack. The clutch pack has a first portion, which is rotatably driven by either or both of the input shaft and the first output shaft, and a second portion that is supported for rotation relative to the first portion. The transfer mechanism couples the second portion of the clutch pack to the second output shaft. The sensor portion is coupled to the first or second output shaft and is at least partially formed of a magnetoelastic material. The magnetoelastic torque sensor is disposed about and radially in-line with the sensor portion.
