A magnetically hinged, overrunning clutch is disclosed. Sprags containing rare-earth permanent magnets, and arranged in pairs of opposite magnetic orientation, are located within the gap between the inner surface of a hollow, circularly cylindrical shaft and the external surface of a smaller diameter, second circularly cylindrical shaft. Pairs of rare-earth permanent magnets encircling the second cylindrical shaft are located at, or just beneath, the surface of the shaft and are arranged in pairs having alternating magnetic orientation. The sprags are cylinders having a pseudo-spiral cross-section and are sized, and the ferromagnetic region located, such that when the sprags are attracted to the shaft-magnets, the first shaft may be rotated with respect to the second shaft in a first, overrunning direction of rotation, but the first shaft does not rotate with respect to the second shaft in an opposite, or lock-up direction.

A magnetic brake assembly for use with a wheel rim is described. The brake assembly includes a rotor secured to rotate with the rim and a stator secured to be rotationally stationary relative to the rotor. One of the rotor and stator has an electrically conductive body and the other of the rotor and stator has a magnetic array including a plurality of magnets configured to generate a magnetic flux. An actuator is connected to at least one of the electrically conductive body and magnetic array to selectively effect a brake mode and a non-brake mode. In the brake mode, the magnetic array induces eddy currents in the electrically conductive body to generate a magnetic braking force when the rim rotates above a threshold speed and in the non-brake mode, the induced eddy currents cause a negligible or no magnetic braking force as the rim rotates above the threshold speed.

Drive systems or powertrains including transmissions for electric and hybrid electric vehicles are provided. In some embodiments, dynamic, 2-position linear motor, one-way clutches are provided. In other embodiments, 3-position linear motor, 2-way clutches are provided.

In a fixed torque ratio operating mode of the powertrain, speed values for the two motors are determined to optimize overall efficiency. A hybrid electric powertrain of at least one embodiment uses the optimized electric vehicle powertrain, an engine and the one-way and 2-way clutches to obtain a highly optimized hybrid powertrain.

A surgical clip applier is disclosed which is configured to automatically feed a clip from a clip cartridge once the surgical clip applier is positioned in the patient.

The disclosure relates to a disengagement system for actuating a clutch, in particular a clutch in the powertrain of a motor vehicle between the drive motor and the transmission, having a threaded spindle which is rotationally fixed to the clutch at an end region and is thus connected to the drive motor. The disengagement system additionally comprises a disengagement unit, having a stator and a rotor which is connected to the stator by an axial bearing, wherein the rotor rotates together with the threaded spindle and is in engagement with the threaded spindle via a spindle nut, and the clutch is actuated by adapting the rotational speed of the rotor.

The clutch mechanism includes a slide member movable inside the differential case in an axial direction and an actuator for moving the slide member in the axial direction. The actuator is located outside the differential case. The slide member includes a first meshable portion and an engaging portion engaging with a pinion shaft of the differential mechanism. The differential case has a second meshable portion to mesh with the first meshable portion and a wall portion having multiple insertion holes for transmitting a moving force of the actuator to the slide member. The slide member is located between the second meshable portion and the wall portion.

A wheel-end disconnect assembly for translating rotational torque between an output shaft and a wheel hub of a vehicle driveline. A knuckle bracket at least partially supports the wheel hub. A clutch is operatively attached to the knuckle bracket, is disposed in selective torque translating relationship between the output shaft and the wheel hub, and is movable between: an engaged configuration wherein torque is translated between the output shaft and the wheel hub, and a disengaged configuration wherein torque is interrupted. An electromagnetic actuator is provided and has a slider selectively movable between a first stable position and a second stable position. The actuator is disposed in force translating relationship with the clutch such that movement from one stable position to the other stable position causes corresponding movement of the clutch between the configurations so as to selectively translate rotational torque between the output shaft and the wheel hub.

A ring insertion groove is formed between adjacent two of circular plates, which are made of a magnetic material and are arranged concentric with each other, and a ring, which is made of a non-magnetic material and has a larger deformation resistance in comparison to the magnetic material of the plates, is press fitted into the ring insertion groove. Thereafter, a peripheral part around an opening of the ring insertion groove is plastically flowed, so that a compression stress is left in the ring.

An electro-mechanical clutch apparatus includes a stationary member (22,122) having a center portion extending along an axis A and a stationary coil assembly (34,134) fixed about the center portion. A rotatable member (46,146) extends along the axis A and includes an annular projection (52,152) radially spaced from the coil assembly. A ratchet surface (29,129) presents a plurality of teeth disposed in axially aligned and radially spaced relationship with the annular projection. The rotatable member includes a magnetic pole piece (62,162) disposed in radially spaced and concentrically aligned relationship with said coil assembly. The rotatable member includes a locking member (58,158) pivotably attached to the annular projection and pivotable between an engaged position in engagement with one of the teeth in response to the coil assembly being de-energized and a released position displaced from engagement with the teeth and attracted towards the magnetic pole piece in response to the coil assembly being energized.
