A differential assembly is disclosed, including a housing forming an interior space, and a shaft may extend into a portion of the interior space of the housing. A side gear including an aperture may be arranged within the interior space and an end portion of the shaft is aligned and extends through the aperture. The differential assembly may further include a sliding sleeve configured with a flat flange portion, the sliding sleeve may extend through the aperture and slide over the end portion of the shaft. Furthermore, a pinion gear may be configured with a flat face portion and a pinion gear cam portion may be configured to extend axially away from the flat face portion of the pinion gear. An actuator may actuate the sliding sleeve between a sleeve first position and a sleeve second position and the flat flange portion may interact with the pinion gear cam portion.

A differential may include a metal plate interlocking with a pinion, and at least one permanent magnet fixable to a case of the differential to generate an eddy current in the metal plate upon a relative rotation of the metal plate.

A differential for a vehicle. The differential includes a cage, which is rotatable about a first axis of rotation and has a drive interface, a first driven gear, mounted in the cage to be rotatable about the first axis of rotation, a second driven gear, mounted in the cage to be rotatable about the first axis of rotation, a compensating gear, which is mounted in the cage about a second axis of rotation extending perpendicularly to the first axis of rotation and meshes with the first and the second driven gear, a flywheel mass, coupled to the cage and locked against rotation with respect to the first axis of rotation and displaceable in a radial direction perpendicularly to the first axis of rotation, and a clutch, which, as a result of an outward movement of the flywheel mass in the radial direction, is movable into a locking state.

A gearbox assembly for a vehicle axle which extends along a rotation axis is disclosed herein and includes: a planetary gear system positioned along the vehicle axle and receiving power from a motor, the planetary gear system comprising a ring gear, a sun gear, a planet, and a planet carrier including an output member; a differential including a shaft which includes an output gear positioned concentrically to the rotation axis along the shaft; a freewheeling gear located concentrically to the output member; a plurality of countershaft assemblies each including: a countershaft rotating about an axis parallel to the rotation axis; and two countershaft gears; and a clutch configured to be operated between a first position where it couples the output member with the freewheeling gear and a second position where it couples the output member with the differential.

A drive control device includes: a meshing engagement unit; an engine; a rotary machine; a detector detecting a predetermined parameter; and a controller configured to perform a release control of causing the rotary machine to output a second rotation torque in a direction opposite to a first rotation torque applied from the engine to the engagement unit at a time the engagement unit is released. The release control includes setting a magnitude of the second rotation torque to a predetermined value larger than a magnitude of the first rotation torque at a time the predetermined parameter change degree is not smaller than a threshold value and gradually decreasing the magnitude of the second rotation torque, and setting the magnitude of the second rotation torque to a magnitude smaller than the predetermined value at a time the predetermined parameter change degree is smaller than the threshold value.
