A number of variations may include a clutch apparatus having at least one clutch and having an actuating device for actuating the clutch, the actuating device being movable from an opening position, in which the clutch is open, into a closing position, in which the clutch is closed. The actuating device can be locked with form-fit action in the closing position or opening position.

A transfer case includes a primary output shaft, and a secondary output selectively coupleable to the primary output shaft with a secondary torque transfer mechanism. The secondary torque transfer mechanism comprises a plate clutch and a locking sleeve. The plate clutch includes a housing coupled to the secondary output shaft, a plurality of interleaved plates alternatingly coupled to the primary output shaft and the housing, and an apply plate coupled to the primary output shaft and being configured to compress the interleaved plates to selectively form a friction coupling between the primary output shaft and the secondary output shaft. The locking sleeve is non-selectively coupled to one of the housing or the apply plate to rotate therewith, and is selectively coupleable to the other of the housing or the apply plate to form a positive coupling between the primary output shaft and the secondary output shaft.

A clutch release bearing (17), in particular for a motor vehicle, having: a tubular body (30) through which at least one input shaft (11) of a gearbox is intended to pass; at least one actuator having a part, movable in translation along the axis (X) of the body (30), intended for actuation of a clutch diaphragm; a target (28a, 28b) whose position is representative of the position of the movable part of the actuator; and a detector (29a, 29b) capable of detecting the position of the target (28a, 28b). The target (28a, 28b) is offset angularly from the detector (29a, 29b) with respect to the axis (X) of the body (30).

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.

A linear drive having a transmission housing and an electric motor which is accommodated in the transmission housing and drives a shaft with a worm. The shaft meshes with a worm gear which can be non-rotatably connected by way of a clutch to a spindle holder non-rotatably connected to a spindle. The clutch is biased by a spring and is adjustable by means of a clutch actuation. To permit simple and rapid operation of the clutch it is proposed that the clutch actuation includes a slide element which bears against the clutch and which is arranged non-rotatably but axially displaceably in relation to the clutch. A rotary element which is axially fixed but rotatable about an axis of rotation engages the slide element at an outside that faces away from the clutch. Run-on bevels of complementary configuration are provided between the slide element and the rotary element. The rotary element is actuable by way of a pulling element.

An actuator assembly comprises a rotatably drivable drive gear; a locking ring which is rotatably mounted in a stationary housing and is drivingly connected to the drive gear, wherein the locking ring is rotatable from a first rotational position into a second rotational position against a rotation stop; wherein at least one friction face pairing is provided in the power path between the drive gear and the locking ring, via which a torque can be transmitted to the locking ring by frictional forces; a first ramp ring drivable by the drive gear and a second ramp ring, which are axially supported against each other and are configured to convert rotary movement into axial movement; wherein the first ramp ring, after the locking ring has reached the rotary stop, can be further rotatably driven by the drive gear.
