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 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. 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 linear actuator means in response to the sensor input signals.

摘要： An electronically controlled shift system is provided for a synchronized manual transmission of a motor vehicle. The shift system provides greater control of gear engagement by determining an optimum shift force at shift time, by adjusting this shift force based upon engine temperature, and by applying variable shift forces to complete a gear shift. In particular, the electronically controlled shift system comprises a manually operated shift lever for selecting a gear, a transmission control module connected to the shift lever for receiving an electrical input signal indicative of a selected gear and a dual motion actuator receiving actuation signals from the transmission control module for actuating a shift rail of the transmission to engage the selected gear. The transmission control module includes a shift-out routine for axially translating the shift rail from a current in-gear position into a neutral position, a shift-across routine for rotating the shift rail (if necessary) from a first neutral position to a second neutral position that aligns with the in-gear position for the selected gear, and a shift-in routine for actuating the shift rail into selected in-gear position. In addition, shift-in routine applies an entry force for taking up synchronizer clearance, determines and applies a synchronization force and applies a lesser end force for easing the shift rail into the in-gear position.

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 power transfer system including a variable speed electric motor and a single speed transmission is disclosed for transferring power from a source of power to a pair of driven wheels. This arrangement is particularly adapted for use in electric vehicles incorporating a high speed electric motor. In a preferred embodiment, the single speed transmission includes a housing, an input shaft for receiving drive torque from the electric motor, at least one output shaft and an intermediate shaft supported for rotation of the housing between the input shaft and the output shaft. The single speed transmission further includes a parking sprag arrangement for preventing rotation of the output shaft when a park mode is selected. In one embodiment, the single speed transmission further includes a transfer mechanism for selectively transmitting the source of drive torque from the input shaft to the output shaft which includes a shift member movable between a first position for preventing relative rotation between the input shaft and the output shaft and a second position for establishing relative rotation between the input shaft and output shaft.

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.
