A slip clutch (19) for a hand-held power tool (1) that serves to uncouple a tool socket (2) from a driving motor (5) in the event of an overload is provided. An annular running surface (23) has cams (24) projecting radially inward. The slip clutch (19) has a set of pairs consisting of a preloaded coil spring (28) and a pawl (29). The coil spring (28) presses a head (38) of the pawl (29) in the radial direction outward onto the running surface (23). The pawl (29) has a sheet-metal strip (34) whose one section is bent into a hollow prism that is annularly closed, except for a gap, in order to form the head (38). An insert (35) is placed into the gap (41) so as to fill the gap (41).

A coupling member for an engageable coupling assembly includes a coupling face having at least one pocket. Each pocket is sized and shaped to receive and nominally retain a locking member that lays down in its pocket during an overrunning condition of the assembly at a laydown angular velocity of the coupling member about a rotational axis of the assembly. Each pocket has a pocket axis which is angled with respect to a normal to a centerline of the coupling member to improve locking member dynamics with regards to strut laydown speed during the overrunning condition.

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.

Disclosed is a hydrokinetic torque converter (TC) with a TC housing. An impeller is disposed within the TC housing and connects to an engine output shaft. A turbine is disposed within the TC housing and connects to a transmission input shaft via a TC output shaft. A torque converter clutch (TCC), which is disposed within the TC housing and coupled to the TC output shaft, selectively locks the impeller to the TC output shaft. A damper, which is disposed within the TC housing and coupled to the TCC, dampens vibrations transmitted by the TCC. A disconnect device, which is disposed within the TC housing and coupled to the damper assembly and TC output shaft, connects the turbine to the TC output shaft or damper when positive torque is being transferred, and disconnects the turbine and TC output shaft or damper when negative torque is being transferred.

Disclosed are engine flexplates with integrated engine disconnects, methods for making and for using such flexplates, and motor vehicles with an engine flexplate having an integrated engine disconnect device. An engine flexplate assembly is disclosed for operatively coupling an engine to a hydrokinetic torque converter. The flexplate assembly includes a disk-shaped body with a central hub that rigidly attaches on the fore side thereof to the engine output shaft for common rotation therewith. A disconnect device, which is positioned on the aft side of the disk-shaped body, includes concentric inner and outer races. The outer race is rigidly attached to the disk-shaped body for common rotation therewith. The inner race rigidly attaches to the front cover of the TC housing for common rotation therewith. The disconnect device operatively disconnects the engine output shaft from the TC housing front cover when a torque transmitted therebetween reverses direction.

A clutch control mechanism configured to allow or block a transmission of a rotation of a handle to a spool in response to either a rotating of the handle or an operating of a clutch operating member. The clutch control mechanism includes a clutch cam, a clutch plate, and a positioning structure. The clutch cam is rotatably mounted to the reel unit, and is rotatable between a first position and a second position. The first position blocks the transmission of the rotation of the handle. The second position allows the transmission of the rotation of the handle. The clutch plate is coupled to the clutch operating member and to the clutch cam, and is unitarily rotatable with the clutch cam. The positioning structure to position the clutch cam from outside in a radial direction about a rotational axis of the clutch cam when the clutch cam is disposed in the first position.

A clutch assembly includes an outer ring having a first and second pocket, and an inner ring. A strut and pawl may be disposed within the first and second pockets. The pawl may be configured such that rotation of the strut pushes the pawl toward teeth of the inner ring for engagement therewith. In a first mode of operation, the pawl does not contact the teeth and the inner ring is free to rotate in the first and second rotational directions. In a second mode of operation, the pawl is in partial engagement with the teeth and the inner ring is free to rotate in the second rotational direction and prevented from rotation in the first rotational direction. In a third mode of operation, the pawl is in full engagement with the teeth and the inner ring is prevented from rotation in both the first and the second rotational directions.
