摘要： A driveline component with a shaft, a friction clutch and a centrifugal valve. The shaft has a supply passage and a feed passage that intersects the supply passage. The centrifugal valve has a valve seat, which is formed on the shaft and intersects the feed passage, a valve element and a flyweight that is pivotally coupled to the shaft. The valve element is received in the valve seat and is movable between a first position, in which the valve element is abutted against the valve seat, and a second position in which the valve element is displaced from the valve seat. The flyweight has a weight and a cam and is configured so that radially outward rotation of the weight in response to centrifugal force causes the cam to drive the valve element toward the first position.

摘要： A transfer case includes a primary output shaft, and a secondary output selectively coupleable to the primary output shaft with a secondary torque transfer mechanism. The secondary torque transfer mechanism comprises a plate clutch and a locking sleeve. The plate clutch includes a housing coupled to the secondary output shaft, a plurality of interleaved plates alternatingly coupled to the primary output shaft and the housing, and an apply plate coupled to the primary output shaft and being configured to compress the interleaved plates to selectively form a friction coupling between the primary output shaft and the secondary output shaft. The locking sleeve is non-selectively coupled to one of the housing or the apply plate to rotate therewith, and is selectively coupleable to the other of the housing or the apply plate to form a positive coupling between the primary output shaft and the secondary output shaft.

摘要： A transfer case includes primary and secondary output shafts, along with a secondary torque transfer mechanism and a locking mechanism, which are configured to selectively couple the primary and secondary output shafts. The secondary torque transfer mechanism comprises a sprocket coupled to the secondary output shaft, and a plate clutch coupled to the sprocket to selectively form a friction coupling with the primary output shaft. The locking mechanism selectively couples the primary output shaft to the sprocket, and includes a locking sleeve and an actuator that moves the locking sleeve between a first position and a second position. In the first position, the locking sleeve forms a first splined connection with the primary output shaft and forms a second splined connection with the sprocket. In the second position, the locking sleeve forms the first splined connection with the primary output shaft and forms a second splined connection with the sprocket.

摘要： A transfer case (26) for translating rotational torque from an engine (22) to first and second differentials (34, 36). A primary shaft (50) is supported in a housing (48) and has an input in communication with the engine (22) and an output in communication with the first differential (34). A secondary shaft (52) is disposed in communication with the second differential (36). A clutch (54) selectively translates torque between the shafts (50, 52) and moves between a first position (54A) wherein torque is translated to the secondary shaft (52), and a second position (54B) wherein torque is interrupted. An actuator (64) with a piston (68) movably supported in a cylinder (66) moves the clutch (54). A lock (70) moves between a locked configuration (70A) engaging the piston (68) to prevent the clutch (54) from moving, and an unlocked configuration (70B) releasing the piston (68) allowing the clutch (54) to move.

摘要： A transfer case comprises a primary output shaft, and a secondary output shaft selectively coupleable to the primary output shaft with a plate clutch to transfer torque therebetween. The plate clutch includes a housing, a plurality of interleaved plates that are engaged alternatingly with the primary output shaft and the housing to rotate therewith, and an apply plate non-selectively coupled to the primary output shaft to rotate therewith. The apply plate is moveable axially along the primary output shaft into a first configuration in which the apply plate is positively coupled to the housing to rotate therewith, a second configuration in which the apply plate rotates independent of the housing, and a third configuration in which the apply plate compresses the interleaved plates to form a friction coupling between the primary output shaft and the housing.

摘要： A transfer case for a motor vehicle. An input is rotatable about an axis to receive torque, an output is rotatable about the axis to transmit torque, and a planetary gear set is rotatable about the axis and operatively coupled between the input and the output. A shift sleeve circumscribes and is axially slidably carried along the axis, and a shift sleeve lock is automatically engageable with the shift sleeve responsive to the transfer case exceeding a predetermined rotational speed, to prevent axial movement of the shift sleeve above that speed. A related method is also provided.
