Methods and systems are provided for an electromagnetic pulse disconnect assembly. In one example, an electromagnetic disconnect assembly includes an electromagnetic coil assembly including an electromagnetic coil, an armature cam including an annular ring and a plurality of bidirectional cam ramps extending in an axial direction from the annular ring, where the annular ring is adapted to have face-sharing contact with the electromagnetic coil assembly when the electromagnetic coil is energized and be spaced apart from the electromagnetic coil assembly when the electromagnetic coil is de-energized, and a cam follower a plurality of radially extending guides arranged around a circumference of the cam follower and spaced apart from one another via a plurality of elongate apertures, each of the plurality of elongate apertures adapted to receive one of the plurality of bidirectional ramps of the armature cam. The assembly may further include a latching system.

A product comprising: an axle shaft and an input shaft, wherein the axle shaft is coaxial with the input shaft; a clutch operatively connected to the axle shaft and the input shaft constructed and arranged to selectively couple and decouple the input shaft and the axle shaft; an actuator operatively connected to the clutch to drive the clutch; and a synchronizer operatively connected to the clutch to synchronize the coupling of the input shaft and the axle shaft.

There is provided a work vehicle including a partition wall to keep partition between a first space zone as part of an internal space of the transmission case in which a differential mechanism is located and a second space zone as part of the internal space which is adjacent to the first space zone. An upper space is disposed above the partition wall and configured to allow lubricating oil scooped up from the first space zone by a ring gear to flow in the second space zone. A flow-out path is disposed below the upper space and configured to allow the lubricating oil to flow out of the second space zone to the first space zone.

By driving a first electromagnetic solenoid and a second electromagnetic solenoid, if first cams of a first thrust force amplification mechanism and a second thrust force amplification mechanism are connected to non-rotary members, since second cams are rotated at rotating speeds that are proportional to a vehicle speed V, the relative rotations between the first cam and the second cam increase. Therefore, the first thrust force amplification mechanism and the second thrust force amplification mechanism can be actuated quickly, to thereby switch connection/disconnection states of the first connection/disconnection mechanism and the second connection/disconnection mechanism quickly.

A multi-axle drive device and method for operating a multi-axle drive device. The multi-axle drive device is provided with a synchronization clutch present in an operational connection between a first output shaft and a connecting shaft and at least one disconnecting clutch present in an operational connection between the connecting shaft and a second output shaft. The synchronization clutch and the disconnecting clutch are opened in a first operating state and closed in a second operating state. At the same time, with an intended change from the second operating state to the first operating state, the synchronization clutch is maintained at least partially opened and the separation clutch is maintained closed, so that, when a first operating mode is carried out, the disconnecting clutch is opened, and when a second operating mode is carried out, the synchronization clutch is closed again.

A clutch assembly comprises a first drive part, a second drive part, a clutch which comprises an axially supported first clutch part and an axially movable second clutch part, wherein the second clutch part can be moved into an open position and into a closed position, wherein a clutch profile of the second clutch part 8 and a drive part profile of the second drive part form a form-locking profile connection such that the second clutch part is connected to the second drive part in a rotationally fixed and axially movable way, wherein the drive part profile comprises central flank lines which are each formed between a tip line and a base line of the drive part profile, wherein the drive part profile is designed such that the central flank lines, when rotating around the rotational axis A, define a rotational face which comprises at least one tapered partial portion. Further disclosed is a driveline assembly with such a clutch assembly.

Some embodiments of the present invention provide a control system configured to control a driveline of a motor vehicle to operate in a selected one of a plurality of configurations, the system comprising at least one sensor for sensing an environment ahead of the vehicle and generating a sensor signal in dependence on the environment, the system being configured to cause the driveline to operate in a configuration selected in dependence at least in part on the sensor signal.

An AWD drivetrain is configured to primarily direct drive torque from a transversely-aligned powertrain assembly through an auxiliary power transfer unit to a rear driveline and selectively transmit drive torque to a front driveline via actuation of at least one power-operated clutch. The auxiliary power transfer unit includes an input component drivingly connected to the powertrain assembly, and an output component connected to the input component by a hypoid gearset The output component is operatively connected to the rear driveline and is configured to normally transfer the drive torque to the rear driveline.

A method and a device for operating a drive train of a motor vehicle are provided. The drive train includes at least a first and a second shaft, a first clutch having at least one first friction surface pairing, and an electric drive, the first and the second shaft being coupleable to one another via the at least one first friction surface pairing, wherein for cooling the first clutch, a fluid is used via which a drag torque of the first clutch is influenced after the first clutch is disengaged, the method including: a) Rotating the first shaft and the second shaft when the first clutch is at least partially engaged; b) Disengaging the first clutch; c) Accelerating the first shaft by means of the electric drive and discharging the fluid from an area of the at least one first friction surface pairing;
wherein the drag torque of the first clutch is reduced by the accelerated discharge of the fluid.
