摘要： A two-speed full-time transfer case includes an input shaft, first and second output shafts, a planetary gearset, an interaxle differential, and first and second clutch mechanisms. The planetary gearset includes a sun gear integral with the input shaft, an annulus gear, and pinion gears rotatably mounted on a carrier and which are meshed with the sun and annulus gears. The interaxle differential has an input driven by the carrier, a first output driving the first output shaft and a second output driving a transfer mechanism coupled to the second output shaft. The first clutch mechanism is a fluid-actuated bi-directional overrunning clutch operable for selectively braking the annulus gear. The second clutch mechanism is a fluid-released bi-directional overrunning clutch for selectively releasing the input shaft from coupled engagement with the carrier.

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.

摘要： The present invention is directed to a power transfer system for a four-wheel drive vehicle equipped with a torque transfer coupling which includes a clutch pack and a ball-screw actuator. The ball-screw actuator functions to axially translates an apply plate to operatively engage the clutch pack and vary the frictional engagement. This arrangement yields numerous operational advantages over the prior art including, but not limited to, establishing a direct drive between the motor output shaft and the apply plate, concentric mounting of the actuator elements with the motor output shaft, and a simplified mechanical arrangement that reduces the number of frictional elements increasing operational efficiency and decreasing motor requirements.
