A transfer case having an input shaft driven by a powertrain, a first output shaft adapted for connection to a first driveline and a torque transfer mechanism. The torque transfer mechanism includes a friction clutch assembly operably disposed between the first output shaft and the second output shaft and a clutch actuator assembly for generating and applying a clutch engagement force to the friction clutch assembly. The clutch actuator assembly includes an electric motor, a geared reduction unit and a clutch apply operator. A control system including vehicle sensors and a controller are provided to control actuation of the electric motor.

Shift system for transfer case

A transfer case having an input shaft driven by a powertrain, a first output shaft adapted for connection to a first driveline, a second output shaft adapted for connection to a second driveline, an interaxle differential operably disposed between the input shaft and the first and second output shafts, and a torque transfer mechanism. The torque transfer mechanism includes a friction clutch assembly operably disposed between the first output shaft and the second output shaft, and a clutch actuator assembly for generating and applying a clutch engagement force to the friction clutch assembly. The clutch actuator assembly includes an electric motor, a geared reduction unit, and a clutch apply operator. A control system including vehicle sensors and a controller are provided to control actuation of the electric motor.

Two-speed transfer case with adaptive clutch control

A transfer case is provided and includes a first output shaft driven by a powertrain and operably interconnected with a first pair of wheels, a second output shaft selectively driven by the first output shaft and operably interconnected with a second pair of wheels and a transfer gear assembly operably disposed between the first output shaft and the second output shaft for transferring drive torque from the first output shaft to the second output shaft. The transfer gear assembly includes a first transfer gear in selective drive connection with the first output shaft, a second transfer gear in meshed engagement with the first transfer gear, a third transfer gear in drive connection with the second transfer gear and the second output shaft. A clutch pack is operably disposed between the first output shaft and the first transfer gear for selectively establishing drive connection therebetween.
