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.

An electrically-operated electric drive module for use in a vehicle framework that is configured for a powertrain that includes an internal combustion engine. The electrically-operated electric drive module permits the vehicle to be converted to an electrically propelled vehicle in a manner that is cost-effective and which is relatively low in weight.

The invention provides a gearing assembly (5) comprising a rotary input member (1b), a rotary output member (3) and a gearing arrangement (52) between the input member and the output member selectively engageable to effect a driving engagement between the input member and the output member through at least a first torque connection having a first gear ratio and a second torque connection having a second gear ratio. One of the rotary input member and the rotary output member comprises a first shaft and the first torque connection comprises a first dog clutch comprising a dog hub (51) comprising a hub set of teeth (51a) and a surrounding dog ring (53) comprising a ring set of teeth (53a), the hub and ring sets of teeth being radially projecting and mutually engageable, the dog hub being mounted on the first shaft so as to allow axial movement of the dog hub relative to the shaft and dog ring with rotation of the dog hub relative to the shaft being resisted such that when the dog hub is axially aligned with the dog ring, the hub and ring sets of teeth engage and rotational drive may be transferred between the first shaft and the dog ring. The hub and ring sets of teeth are dimensioned and spaced so that upon axial movement between the dog hub and the dog ring with the sets of teeth appropriately in register with one another, the teeth in each set may pass through spacings between the teeth in the respective other set, so that the dog hub is moveable between a first disengaged position with the hub set of teeth axially spaced in a first direction from the ring set of teeth, a first engaged position with the hub set of teeth aligned and engaged with the ring set of teeth, and a second disengaged position with the hub set of teeth axially spaced in a second direction from the ring set of teeth.

A freewheeling system for tandem axles, the system including a wheel hub, a wheel hub cover attached to an end of the wheel hub, the wheel hub cover having tines predicted thereon, an actuator chamber, a piston, a sleeve, an axle shaft, and at least one air input. The at least one air input feeding the actuator chamber in which is accommodated the piston that is engaged in the sleeve concentrically mounted in an end of the axle shaft having axial mobility, wherein the sleeve has a flange endowed with tines that mechanically cooperate with the tines predicted on the wheel hub cover.

The assembly may further include a latching system.

A drive switching mechanism of a utility vehicle includes: a two-wheel drive and four-wheel drive switching device that switches between two-wheel drive and four-wheel drive of the utility vehicle; and a control unit that controls the drive switching mechanism. The two-wheel drive and four-wheel drive switching device switches between two-wheel drive and four-wheel drive by using a first clutch. The control unit permits the two-wheel drive and four-wheel drive switching device to switch from two-wheel drive to four-wheel drive when a rotation difference of the first clutch becomes equal to or smaller than a predetermined value.

A drive control device for a vehicle is configured: to determine whether or not a sound pressure level inside a vehicle cabin becomes a predetermined value or less, under a state where it is predicted that a meshing-type engagement mechanism is changed from a disengaged state to an engaged state; and to prohibit the meshing-type engagement mechanism from entering the disengaged state, when it is determined that the sound pressure level becomes the predetermined value or less. In the disengaged state, transmission of a power output from a driving force source to driving wheels as drive energy is interrupted.

A vehicle driveline component that employs a latching actuator to toggle between a first operation mode and a second operational mode. The latching actuator includes first and second actuator structures, a biasing spring, which biases the second actuator structure away from the first actuator structure, a linear motor, which can be operated to drive the second actuator structure toward the first actuator structure, and a plurality of linkages that cooperate with the biasing spring to releasably lock the second actuator structure relative to the first actuator structure in each of an extended position and a retracted position.
