A laundry treatment apparatus includes: a tub, a drum rotatably provided in the tub, an agitator rotatably provided in the drum, a driver coupled to the tub and configured to provide power for rotating at least one of the drum or the agitator, and a clutch unit provided between the driver and the agitator to transmit the power from the driver to at least one of the drum or the agitator. The clutch unit includes: a gear unit configured to rotate based on being engaged with the driver, a rotary shaft coupled to the gear unit and configured to rotate the agitator, a housing coupled to the drum and that accommodates the gear unit and the rotary shaft, a coupler configured to reciprocate between the housing and the driver and rotate the housing, a moving unit including the coupler to reciprocate the coupler, and an actuator reciprocating the moving unit.

A disconnect apparatus including a first clutch member and a second clutch member in selective engagement with the first clutch member. The disconnect apparatus also includes a cam mechanism and a sensor assembly. The cam mechanism includes an axially movable first cam member and an axially fixed second cam member, wherein the sensor assembly generates a pulse pattern which is utilized to determine a position of the first cam member, and thereby a state of the disconnect apparatus.

An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a second electric motor that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a clutch. The electric powertrain further includes a first gear train in the form of a first planetary gear and a second gear train in the form of a second planetary gear. The clutch in one variation includes a positive clutch in the form of a dog clutch. The dog clutch has a clutch suspension configured to deflect a clutch collar when gearing is misaligned during shifting.

The disclosure relates to a claw coupling for interlockingly connecting a first rotatable component to a second rotatable component, wherein a sliding sleeve is non-rotatably and axially slidably arranged on the first rotatable component and a coupling body is non-rotatably arranged on the second rotatable component, the sliding sleeve being axially movable for interlocking connection to the coupling body in order to connect the first component to the second component, at least one spring-loaded shifting ring being movably mounted, non-rotatably and axially relative to the sliding sleeve, on the sliding sleeve, and a damping chamber, formed in dependence on the relative motion, is provided in order to delay the axial motion. The disclosure further relates to an electrical drive axle of a vehicle having at least the claw coupling. In addition, the disclosure relates to a method for interlockingly connecting the first rotatable component to the second rotatable component via a claw coupling.

An engine transmission is provided with an interference member that is configured to interfere with one of a low-gear clutch sleeve and a high-gear clutch sleeve so that when one of the low-gear clutch sleeve and the high-gear clutch sleeve is at an engagement position, the other one of the low-gear clutch sleeve and the high-gear clutch sleeve cannot move to an engagement position.

Claw-type shifting mechanism (5) with a first sliding sleeve (17) and a fixed coupling element (19). In order to produce a passage, the first sliding sleeve (17) and the coupling element (19) each respectively have at least one recess (31, 35) and at least one web section (32, 36), in which the first sliding sleeve (17) and the coupling element (19) can be arranged together radially on the outside on a first shaft. The first sliding sleeve (17) can be displaced along the first shaft and the coupling element (19) can be connected firmly to the first shaft. The drive arrangement (1) comprises at least one drive machine, a transmission with a first shaft, a second shaft and a third shaft, a housing, and a claw-type shifting mechanism (5) of this type.

A dog clutch engagement method of an electric four-wheel drive vehicle includes steps of: when dog clutch engagement is requested during driving, determining a target synchronization speed of the input gear to be a sum of an estimated speed and an offset speed of the output gear; operating a drive unit so that an input gear follows the target synchronization speed; when an actual speed of the input gear reaches the target synchronization speed, moving a sleeve to a meeting position at which the sleeve is in contact with the input gear; and when the actual speed of the input gear is synchronized with an actual speed of the output gear, transporting the sleeve to an engagement position at which the input gear and the output gear are coupled.

A wheel disconnect clutch includes a housing attachable to a knuckle and a clutch sleeve slidably supported for axial movement within the housing and having first teeth configured to couple with a wheel hub and second teeth configured to couple with a half shaft. The clutch sleeve is slidable between an engaged position in which the first teeth are coupled to the wheel hub and a disengaged position in which the first teeth are decoupled from the wheel hub. A drive ring is connected to the clutch sleeve and supported within the housing to be axially slidable and rotationally fixed relative to the housing. An actuator ring is disposed adjacent to the drive ring, supported for rotation within the housing, and axially fixed relative to the housing. The driver ring moves the clutch sleeve between engaged and disengaged positions.

The electronic IWE actuator includes an electric motor, a worm gear connected to the electric motor, a ball ramp including a worm wheel configured to engage with the worm gear, a clutch ring configured to engage with a wheel hub of the vehicle, and a shift fork configured to engage with the clutch ring and the ball ramp and move linearly in a direction along an axis of the wheel hub in response to a rotation of the ball ramp. The clutch ring is configured to engage with the wheel hub in response to a rotation of the worm gear in a first direction, and disengage from the wheel hub in response to a rotation of the worm gear in a second direction that is opposite to the first direction.
