摘要： The present invention is directed to an improved "on-demand" power transfer system of the type having a transfer mechanism incorporated into the driveline of a four-wheel drive vehicle. The transfer mechanism is arranged to deliver drive torque to the driven wheels so as to establish a two-wheel drive mode of operation. In addition, the transfer mechanism is equipped with a clutch assembly for selectively delivering drive torque to the non-driven wheels for establishing a four-wheel drive mode of operation. The transfer mechanism is further equipped with a rotary actuator mechanism for actuating the clutch assembly. The rotary actuator mechanism is preferably mounted directly to the transfer mechanism to substantially minimize the packaging requirements associated with the on-demand power transfer system while concomitantly enhancing in-service reliability and allowing pre-assembly of the transfer mechanism prior to final installation into the vehicle driveline. The power transfer system further includes sensors for detecting various dynamic and operational characteristics of the vehicle and generating sensor input signals indicative thereof, and a controller for controlling actuation of the rotary actuator means in response to the sensor input signals.

摘要： The present invention provides a power transfer system for a four-wheel drive vehicle which permits the vehicle operator to choose between operation in conventional two-wheel drive and four-wheel drive modes or an "on-demand" four-wheel drive mode. The power transfer system is operable for disabling the on-demand four-wheel drive feature upon the vehicle operator subsequently shifting into either of the two-wheel drive and the four-wheel drive modes. The system includes a transfer mechanism having a first and second output members coupled to first and second sets of wheels, respectively. The transfer mechanism has a transfer clutch that is operable for transferring drive torque from the first output member to the second output member to establish the part-time four-wheel drive and on-demand modes. A coupling mechanism is provided for mechanically coupling the first and second output members under certain conditions.

摘要： The present invention is directed to an improved "on-demand" power transfer system of the type having a transfer case incorporated into the driveline of a four-wheel drive vehicle. The transfer case is arranged to normally deliver drive torque to the driven wheels so as to establish a two-wheel drive mode of operation. In addition, the transfer mechanism is equipped with a clutch assembly for selectively delivering drive torque to the non-driven wheels for establishing an on-demand four-wheel drive mode of operation. The transfer mechanism is also equipped with a rotary actuator and a drive mechanism for actuating the clutch assembly. The power transfer system further includes sensors for detecting various dynamic and operational characteristics of the vehicle and generating sensor input signals indicative thereof. A controller is provided for processing the input signals and controlling actuation of the rotary actuator in response thereto. In one preferred construction, a shift mechanism is used in conjunction with the drive mechanism for selectively de-coupling the output shafts of the transfer case from its input shaft so as to establish a non-driven Neutral mode.
