    Abstract: The invention concerns a method for actuating a differential lock of a differential in a motor vehicle drive-train, such that when a locking command has been issued the differential lock is engaged as soon as there is essentially no rotational speed difference at the differential lock (S8). To carry out a comfort-orientated actuation of the differential lock, when the locking command has been issued but before the differential lock is engaged, it is first checked whether there is a rotational speed difference at the differential lock (S6). If there is a rotational speed difference, this is automatically reduced before the differential lock is engaged (S7).

  • 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.

  • Patent number: 10167939
    Abstract: A dog clutch includes: a first rotational member; a second rotational member; a clutch member; and a pressing mechanism. The clutch member includes a meshing portion meshing with the second rotational member, an engageable portion circumferentially engaging with an engaged portion provided in the first rotational member, and a cam surface configured to generate a cam thrust in a direction of a rotation axis by a relative rotation with respect to the first rotational member. When the clutch member moves, a depth of meshing with the second rotational member is deepened by the cam thrust, and then the engageable portion engages with the engaged portion, so that the clutch member receives a torque from the first rotational member.

  • Patent number: 10124451
    Abstract: The present teachings provide for a power transfer device and method of forming a power transfer device that includes a unitarily formed transfer member and a support member. The transfer member can be supported within a housing for rotation about an input member and can be coupled to the input member to receive rotational power therefrom. A ring gear defined by the transfer member can meshingly engage with a pinion gear. The support member can be disposed concentrically about the input member and be rotatable about a first axis relative to the housing. The support member can have a first end and a second end. The first end of the support member can be supported for rotation relative to the housing by a support bearing. The second end of the support member can be received within a bore defined by the transfer member and fixedly coupled thereto for common rotation.

  • Patent number: 10006507
    Abstract: A multi-mode clutch module includes first and second races, and a plurality of race engagement mechanisms situated between the races. The module incorporates an actuator sleeve having an axially acting actuator cam finger. The cam finger is configured with variable radial thicknesses to provide a plurality of predetermined fixed positions for contacting the race engagement mechanisms to cause the engagement mechanisms to selectively interact with the races. The actuator sleeve is thus adapted to control axial movement of the actuator cam finger between at least two axially spaced positions in one embodiment. In other embodiments within the scope of this disclosure, the actuator cam finger may be adapted to move axially among any number of predetermined positions to operatively permit or prevent transmittal of torque between the first and second races, irrespective of the relative rotational direction of the races.
