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 saddle ride type vehicular dry clutch having passive clutch disc of co-axial fixed plane contact, used for seamlessly undertaking the drives from the drive bearing assembly, in which the drive bearing assembly includes a bearing body and an active disc, and the saddle ride type vehicular dry clutch comprises: a clutch device, including a drive axle body formed with a central through-hole, having non-planar guiding slide grooves and an axle body perimeter edge remote from the central through-hole; a passive clutch disc, having a contact surface and a friction drive surface, and assembly ports for assembling elastic components outside of the engage drive area; centrifugal rollers, accommodated within the non-planar guiding slide grooves; and the driven devices includes a drive disc, formed with radially symmetric drive snap ports; a clutch shell, having a tubular inner wall, a surrounding outer wall and a connection wall.

Described herein is a system, method of use and Self Retracting Lifeline (SRL) apparatus using a system that governs a dynamic response between members causing a halt in relative motion between the members. Magnetic interactions, eddy current drag forces and centrifugal and/or inertial forces may provide various mechanisms of governing movement.

Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetically induced force that introduces a force threshold that, in effect, provides a threshold to part movement and confers a degree of hysteresis, preventing movement until a sufficiently large energizing force is applied. The effect may be further altered by use of an additional magnetically induced force interaction with at least one further member to urge or slow movement once started and/or to prevent movement once a new position is reached.

A transmission clutch module includes an inner race, an outer race, and a plurality of race engaging pawls adapted to selectively secure the races together in either a locked position or an unlocked position. The clutch module includes 5 an actuator cam configured to be moved between two angularly spaced positions to control the pawls. The inner race is comprised of two axially spaced inner race plates axially secured together by rivets for retaining, and accommodating angular limited movements of the pawls. The pawls are circumferentially disposed about the inner race plates, and are radially outwardly biased by springs 10 to engage the outer race, unless blocked by the actuator cam. The pawls are weighted at one end, so that at a threshold speed of the inner race, they can overcome spring resistance to disengage from both the actuator cam and the outer race.

A bi-directional coupler that selectively couples and de-couples a driving element to a driven element. The coupler includes an outer shaft having an outer shaft slot and an inner shaft having an inner shaft slot, where the inner and outer shafts are configured to rotate independently of each other. The coupler also includes a ball bearing provided within the inner shaft slot and having a size so that when the ball bearing is located at a center portion of the inner shaft slot it does not interfere with rotation of the outer shaft, where the ball bearing is held in that location by a magnet located in the inner shaft. Rotation of the inner shaft above a predetermined rotational speed causes the ball bearing to engage the outer shaft slot so as to cause the inner shaft to be locked to the outer shaft and rotate therewith.

A clutch includes balls, an axle, a socket and a cylinder. The axle includes a circular section formed with alternate cavities and ridges. The socket includes a circular bore for receiving the circular section of the axle and apertures for receiving the balls. The cylinder includes an annular recess made in an internal face. The socket is movable in the cylinder between two positions. When the socket is the first position, the internal face of the cylinder abuts the external portions of balls to engage the internal portions of the balls with the ridges to cause the axle to rotate the socket via the balls. When the socket is in the second position, the annular recess receives the external portions of the balls to allow disengagement of the internal portions of balls from the ridges to allow the axle to rotate relative to the socket.

A centrifugal clutch (1) for a drive train of a motor vehicle, has an input component (2) which serves for the introduction of torque, an output component (3) which serves for the discharge of torque. The clutch includes an engine-side centrifugal mass (5) and a transmission-side centrifugal mass (6) for actuating the friction unit (4), which centrifugal masses (5; 6) are operatively connected to an engine-side and transmission-side bent sheet metal piece (7, 8). At least one of the centrifugal masses (5; 6) has a cut-out (9) which is such that at least one device (10) which is fixed to the input component has an arm (11) which engages into the cut-out (9) in such a way that guidance of the radial displacement of at least one of the centrifugal masses (5; 6) is ensured.
