摘要： A transfer case includes an input shaft and first and second output shafts. An overdrive unit is driven at an increased speed relative to the input shaft. A clutch is operable in a first position to establish a drive connection between the input shaft and the first output shaft. The clutch is further operable in a second position to establish a drive connection between the overdrive unit and the first output shaft. An actuator is driven by a motor for moving the clutch between its first and second positions. The actuator includes an axially movable fixed disk fixed for rotation with an output member of the overdrive unit. The shift engages an axially movable sleeve of the clutch.

摘要： A full-time power transfer system is disclosed to include a transfer case having a clutch assembly arranged to control speed differentiation and torque biasing across an interaxle differential, sensors for detecting and generating sensor signals indicative of various dynamic and operational characteristics of the vehicle, and a controller for controlling actuation of the clutch assembly in response to the sensor signals. Upon the occurrence of traction loss, the clutch assembly is automatically actuated for limiting interaxle slip while transferring increased drive torque to the non-slipping driveline. Under a preferred adaptive control scheme, the actuated condition of the clutch assembly is controllably modulated between its non-actuated and fully-actuated limits for automatically varying the magnitude of speed differentiation and torque biasing across the interaxle differential in response to changes in the dynamic and operational characteristics of the vehicle.

摘要： A transfer case for a four-wheel drive vehicle having a planetary gear assembly which integrates a gear reduction unit and an interaxle differential into a common assembly. A synchronized range clutch is operably associated with the input to the planetary gear assembly and can be selectively shifted on-the-fly for establishing high-range and low-range speed ratios. A synchronized mode clutch is operably associated with the output of the planetary gear assembly and can be selectively shifted on-the-fly for establishing two-wheel, full-time four-wheel and locked four-wheel drive modes.
