CLUTCH FOR CONTINUOUSLY VARIABLE TRANSMISSION
A continuously variable transmission includes a first shaft driveably connected to a power-plant and having a first pair of sheave disks, and a second shaft having a second pair of sheave disks. A tension member is connected to the first and second pairs of disks such that power is transmittable between the first and second shafts. A third shaft is selectively driveably connected to the second shaft via a clutch. The clutch includes an inner race fixed to one of the second and third shafts, and an outer race fixed to a gear and having an inner surface circumscribing the inner race. At least one pawl is biased to couple the races in a fixed relationship for common rotation. The clutch further includes an electric coil and an armature configured to engage the pawl to decouple the races in response to current being supplied to the electric coil.

Rotating Multi-Mode Clutch Module with Stationary Actuator
A multi-mode clutch module for connecting two components rotating relative to each other may include an outer race, an inner race and pawls coupled to the inner race and movable between engagement to and disengagement from the outer race to alternately lock and unlock the races for relative rotation in one or both directions. A cam ring and a plurality of cams extending therefrom are coupled to the inner race for rotation therewith and for axial movement parallel to a rotational axis of the races. A shift ring is operatively connected between the cam ring and a shift drum such that rotation of the shift drum caused by a stationary actuator causes translation of the shift ring to move the cam ring and cams so the cams engage the pawls to move the pawls between their locked and unlocked positions.

Freewheel
A freewheel has a first ring which has a first blocking contour on a first axial side and a second ring which is rotatable relative to the first ring and which has a second blocking contour on a second axial side pointing toward the first axial side of the first ring. Tiltable blocking bodies can be caused to engage into the first blocking contour and into the second blocking contour. A switching element tilts the blocking bodies. A displacement unit axially displaces the second blocking contour relative to the first ring between an active setting, which is axially approximated to the first ring, and an inactive setting, which is axially remote from the first ring and in which torque-transmitting blocking of the first ring with the second ring is prevented in any setting of the blocking bodies.

FREEWHEEL FOR A MOTOR VEHICLE DRIVE TRAIN
A freewheel for a motor vehicle drive train includes a locking pawl carrier which is rotatable with respect to a rotational axis, first and second locking pawls fastened pivotably in a locking pawl receptacle where the locking pawl receptacle is fixedly coupled to the locking pawl carrier. A shaft is rotatable about the rotational axis and has first and second coupling depressions in which the first and second locking pawls are respectively engageable. A switching ring is coupled fixedly to the locking pawl carrier so as to rotate with the locking pawl carrier and the switching ring is movable along the rotational axis by an actuator. A position of the switching ring is detectable by a sensor. A movement of the switching ring in one direction loads the first and second locking pawls in opposite pivoting directions and fixes a position of the first and second locking pawls.

Selectable one-way clutch with improved electromagnetic module
A controllable one-way clutch assembly having an electromagnetic actuator module equipped with an energizeable coil assembly, a strut moveable in response to energization of the coil assembly from a released position to a locked position, and a latching mechanism operable to releaseably hold the strut in the released position when the coil assembly is not energized.
MULTIMODE CLUTCH ARRANGEMENTS
A clutch for selectively preventing rotation of a rotating component may include a first and second pawls pivotable between engagement and disengagement with the rotating component to selectively prevent or allow rotation of the rotating component in one or both directions. An armature moveable between a first and second armature positions may have a common member pivotally connected thereto and engaging the first and second pawls, with a torque spring biasing the common member to rotate toward the first pawl and away from the second pawl. In an intermediate armature position, the common member may disengage the first pawl from the rotating component while engaging the second pawl to allow rotation in one direction while preventing rotation in the opposite direction. In embodiments, a clutch may include a cam actuator rotating to selectively control engagement of the pawls with the rotating component and locking in one or both directions.
