  • Patent number: 10183577
    Abstract: 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.

  • Publication number: 20190017433
    Abstract: A linkage extends between an actuator and a valve in a turbocharger. The linkage comprises two spaced member bodies having central portions with opposing curved shapes that extend between ends translatable along and rotatable about spaced pivots. Translation of one member toward the other member compresses the central portions, increasing overall stiffness of the linkage, and translation of one member away from the other member creates a gap between the central portions, allowing independent translation of the ends along the spaced pivots to compensate for misalignment between the actuator and the valve caused by heat and vibration. Another linkage extending between an actuator and a valve in a turbocharger includes two planar spaced member bodies extending between ends translatable along and rotatable about spaced pivots. The two member bodies have different thicknesses.

  • Patent number: 10151359
    Abstract: A multi-mode clutch module for connecting two components rotating relative to each other may include an outer race, an inner race and pawls coupled to the inner race and movable between engagement to and disengagement from the outer race to alternately lock and unlock the races for relative rotation in one or both directions. A cam ring and a plurality of cams extending therefrom are coupled to the inner race for rotation therewith and for axial movement parallel to a rotational axis of the races. A shift ring is operatively connected between the cam ring and a shift drum such that rotation of the shift drum caused by a stationary actuator causes translation of the shift ring to move the cam ring and cams so the cams engage the pawls to move the pawls between their locked and unlocked positions.
