The first clutch element is produced according to a powder-metallurgical or an additive method and has at least one centering projection arranged on the first end face and extending towards the third clutch element to cooperate with and/or be accommodated with a centering recess in an end face in the third clutch element in a positive locking and/or force-fit manner.

Methods and systems for a clutch assembly in an electric drive axle of a vehicle are provided. In one example, a clutch assembly in a gear train is provided that includes a locking clutch. The locking clutch includes a gear including a plurality of teeth having at least one tooth with a tapered end, an indexing shaft rotationally connected to an output shaft, a shift collar mounted on the indexing shaft, configured to translate on the indexing shaft into an engaged and disengaged configuration, and including a plurality of teeth on a face, where at least one tooth in the plurality of teeth in the shift collar includes a tapered end, and an indexing mechanism coupled to the shift collar and the indexing shaft and configured to accommodate for indexing between the indexing shaft and the shift collar during shift collar engagement.

The invention provides a locking device for preventing movement between two elements (11, 12) that are mounted to move relative to each other, the locking device including a lock (31) mounted to rotate relative to one of the elements in order to present successive angular positions for locking and for release in which the lock alternates between preventing and allowing relative movement between the two elements, the lock being constrained to rotate with a selector (55) of an angular indexing mechanism (50) actuated by a pulse-controlled actuator (70, 71) arranged to push the selector against a spring member (58) in order to cause it to turn on each pulse and thereby cause the lock to pass from one angular position to the other.

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 dynamic controllable dog clutch (DCDC) includes a pocket plate, a notch plate, and a linear actuator having a stator and a translator. The translator is axially movable between (i) an engaged position in which a locking member axially extends through the a pocket of the pocket plate and engages a notch of the notch plate to thereby mechanically couple the pocket plate and the notch plate together to prevent relative rotation of the pocket plate and the notch plate with respect to each other about a common rotational axis and (ii) a disengaged position in which the locking member is disengaged from the notch of the notch plate to thereby mechanically decouple the pocket plate and the notch plate together to enable relative rotation of the pocket plate and the notch plate with respect to each other about the common rotational axis.

A quick disconnect system includes a main shaft, a sprocket shaft mounted around the main shaft, a coupler configured to move relative to the main shaft and the sprocket shaft between a connected configuration wherein the coupler is configured to connect the main shaft to the sprocket shaft such that torque is transferred between the main shaft and the sprocket shaft, and a disconnected configuration wherein the main shaft is configured to rotate relative to the sprocket shaft, and a release button configured to be actuated to release the coupler from the connected configuration or the disconnected configuration.

A coupling device for coupling two components in a torque-conducting manner is described. It comprises a first coupling component having a first external toothing and a second coupling component having a second external toothing. In addition, the coupling device has a sliding sleeve having an internal toothing which is permanently engaged with the first external toothing and can be selectively brought into engagement with the second external toothing. Furthermore, a locking unit is provided which can selectively assume a locking state in which the sliding sleeve is held in a form-fitting manner in a rotationally coupled state. In addition, the locking unit can selectively assume an unlocking state. A method of operating a coupling device is also presented.

The Shaft Spring Cutch is an apparatus, used to drive fasteners, or the like, that is multi-directional, and non-ratcheting, comprised of two drive members, separated and held in an unengaged position by a return spring, that are axially retained within a guide housing. The first drive member is attached to a handle or input shaft. The second drive member is attached to a drive bit. When in an unengaged position, the handle, or input shaft, can rotate freely in either direction relative to the drive bit. The first and second drive members are engaged by applying axial force sufficient to overcome the return spring force, which locks the handle, or input shaft, and drive bit together. Once engaged, any rotational force applied to the handle, or input shaft, is transferred to the drive bit. Optionally, the apparatus may be locked together for continuous drive bit engagement using a locking mechanism and a fastener can be placed directly on the drive bit, then using a feature of the tool, the fastener can be spun by hand until set.
