A clutch is provided with a drive-side rotational body and a driven-side rotational body, which can move in the axial direction between a coupled position and a decoupled position. The driven-side rotational body has a groove having a helical portion and an annular portion that is deeper than the helical portion. The driven-side rotational body is urged toward the coupled position by an urging member. The driven-side rotational body is moved to the decoupled position against the urging force of the urging member by insertion of a pin into the helical portion. A projection is provided on the tip of the pin, and a recessed groove for accommodating the projection when the pin is inserted into the helical portion is provided in the bottom surface of the helical portion.

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 clutch assembly includes a pocket plate having a pocket and a teeter-totter strut retained in the pocket. The teeter-totter strut is pivotable to an engaged position in which an engagement face of the teeter-totter strut extends out from the pocket plate. The teeter-totter strut is pivotable from the engaged position to a disengaged position in which the engagement face of the teeter-totter strut does not extend out from the pocket plate. The clutch assembly is configured so that when a shock load force acts on the teeter-totter strut, the teeter-totter strut is prevented from moving into the engaged position.

A surgical instrument comprising a shiftable transmission is disclosed. The transmission comprises a mechanism for assuring that the transmission is in one of a plurality of predefined configurations.

A shifting group for a drive train of a motor vehicle for coupling and decoupling a drive shaft of a drive train as required, with an actuator for actuating a blocking element, a selector rod and a selector fork which is connected to the selector rod. The first drive shaft and the second drive shaft are arranged coaxially with respect to one another, the blocking element blocks an axial displacement of the selector rod in a first switching position and enables said axial displacement in a second switching position, the selector fork engages into a groove of one of the drive shafts, an actuation of the shifting group brings about an axial displacement of a drive shaft, and a clutch between the first drive shaft and the second drive shaft is opened or closed by way of the axial displacement of the selector fork.

A disconnect system for selectively engaging and disengaging one or more shafts of a power train unit. The disconnect system includes a plurality of cam members and an electromagnetic coil. At least one cam member rotates at the same speed as an input shaft. At least one cam member rotates at variable speeds. In operation, the electromagnetic coil is energized by rotation of the input shaft for selectively activating a clutch to engage one or more of the cams to connect and disconnect one or more output shafts.

A locking device comprising: first and second flanges; and first and second flange locking structures. The first and second flange locking structures are used for selectively locking the first flange and the second flange. Each flange locking structure comprises: a synchronising ring and a driving assembly. The synchronising ring is able to slide relative to the corresponding flange; and the drive assembly is capable of selectively pushing the synchronising ring to slide along the axial direction of the corresponding flange from an unlocked position to a locked position.
