摘要： The present invention provides a motor vehicle cold shift assist system for selectively and automatically connecting the non-driven wheels to its associated axle drive mechanism under certain operational and temperature conditions for counteracting the inertial loading acting on the transfer case synchronizer clutch mechanism. The present invention substantially reduces the shift resistance encountered upon the vehicle operator subsequently shifting into the four-wheel drive mode during cold weather 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.

The transfer mechanism is further equipped with a linear actuator mechanism for actuating the clutch assembly. The linear 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.

摘要： The present invention provides a motor vehicle traction control system for providing on-demand four-wheel drive under certain tractive and operational conditions. The traction control system permits the vehicle operator to choose between operation in the conventional two-wheel drive and four-wheel drive mode or the "on-demand" four-wheel drive mode. Moreover, the traction control 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.

摘要： The present invention provides a hydraulically-actuated shift system that is operable for shifting a mechanical shift apparatus of a power transfer device between first and second operative positions. The hydraulically-actuated shift system includes a hydraulic circuit for providing a source of hydraulic power, a hydraulic actuator for selectively moving a clutch sleeve of the mechanical shift mechanism between the first and second drive positions, and an electric control circuit for controlling selective actuation of the hydraulic actuator. The shift system is particularly well-suited for use with four-wheel drive transfer cases for permitting the vehicle operator to shift between two-wheel and four-wheel drive modes and or between various speed ranges.
