The Shaft Spring Cutch is an apparatus, used to drive fasteners, or the like, that is multi-directional, and non-ratcheting, comprised of two drive members, separated and held in an unengaged position by a return spring, that are axially retained within a guide housing. The first drive member is attached to a handle or input shaft. The second drive member is attached to a drive bit. When in an unengaged position, the handle, or input shaft, can rotate freely in either direction relative to the drive bit. The first and second drive members are engaged by applying axial force sufficient to overcome the return spring force, which locks the handle, or input shaft, and drive bit together. Once engaged, any rotational force applied to the handle, or input shaft, is transferred to the drive bit. Optionally, the apparatus may be locked together for continuous drive bit engagement using a locking mechanism and a fastener can be placed directly on the drive bit, then using a feature of the tool, the fastener can be spun by hand until set.

A clutch assembly incorporated into a power transfer assembly (72) of a motor vehicle is presented. The clutch assembly includes a power-operated clutch actuator (306) for moving a clutch sleeve (354) axially between released and engaged positions between two rotatory members. In the released position, relative rotation between two rotary members is prevented. Whereas in the engaged position, relative rotation is permitted. The power-operated clutch actuator (306) further includes an electromagnetic solenoid with an output member having an extended condition and a retracted condition urging the clutch sleeve (354) between positions. A shift isolation linkage mechanism (304) interconnects the output member of the solenoid to the clutch sleeve (354) and permits movement of the output member to its retracted position while a blocked tooth condition inhibits movement of the clutch sleeve (354) to its engaged position. Once the blocked tooth condition is removed, the isolation linkage mechanism (304) forces the clutch sleeve (354) to its engaged position.

A generator drive disconnect device comprising a drive transfer means (100) having a connected configuration, and a disconnected configuration. The disconnect device further comprises a disconnect mechanism, configured to move the drive transfer means from the connected configuration to the disconnected configuration, and a latch mechanism configured to the hold the drive transfer means in the disconnected configuration. The latch mechanism includes a latch member, which is moveable between a retracted position and an extended position, and a biasing mechanism. The biasing mechanism is configured to generate a biasing force to bias the latch member towards the extended position and to apply a reaction force to the latch member to resist movement of the latch member towards the retracted position, the reaction force having a magnitude which increases as a function of the distance of the latch member from the retracted position.

A power transmission mechanism for a turbomachine is provided, having a reduction gear having a first gear and a second gear having different reduction ratios and each having a first gear wheel mounted so as to be able to rotate freely on a shared first axle and a second gear wheel mounted on a shared second axle; and a coupling member having an annular body with an axis of revolution having first and second rows of helical coupling teeth, which are respectively oriented opposite and substantially parallel to the first and second directions, the coupling member being mounted so as to rotate with and slide axially on said first axle so as to occupy at least two predetermined axial meshing positions in which the coupling teeth mesh with complementary meshing projections of one of the first gear wheels which is then made to rotate with the first axle.

A torque-transmitting clutch includes a first clutch element having a first base body and a first end face, a second clutch element, and a third clutch element having a third base body. In a closed position, the first and the second clutch elements are connectable in a positive locking and/or force-fit manner for transmitting torque, and in an open position, this positive locking and/or force-fit connection is released, and wherein the first clutch element is connectable to the third clutch element in a positive locking and/or force-fit manner. The first clutch element is produced according to a powder-metallurgical or an additive method and has at least one centering projection arranged on the first end face and extending towards the third clutch element to cooperate with and/or be accommodated with a centering recess in an end face in the third clutch element in a positive locking and/or force-fit manner.

A clutch assembly or module having multiple one-way clutches, each clutch operates independently of the others to control torque transmission to and from a common or shared notch plate. The assembly or module also controls rotation, including the direction thereof, of the common or shared notch plate. Depending upon the position of each one-way clutch, multiple modes of torque transfer and common or shared notch plate rotation can be achieved.

An engine transmission is provided with an interference member that is configured to interfere with one of a low-gear clutch sleeve and a high-gear clutch sleeve so that when one of the low-gear clutch sleeve and the high-gear clutch sleeve is at an engagement position, the other one of the low-gear clutch sleeve and the high-gear clutch sleeve cannot move to an engagement position.

Transmission systems, disconnect mechanisms, and methods of assembling disconnect mechanisms are envisioned. A disconnect mechanism is adapted to selectively decouple a driving device from a driven device. The disconnect mechanism includes a lever, an inner shaft, an outer shaft, and a housing. The inner shaft is coupled to the lever, the outer shaft is coupled to the inner shaft, and the housing at least partially houses the inner shaft and the outer shaft.

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 power transmission device is provided to provide a 6 forward and 1 reverse transmission capable of smoothly performing 6 forward and 1 reverse or 4 forward and 1 reverse shifting. The power transmission device includes: a first shift input unit in which a reverse clutch and a first shift high clutch are provided at both ends and a first shift low gear is installed to be constrained by a first shift one-way gearing in one direction so that a driving force from a power input unit is transmitted thereto; a firs shift output unit to which a driving force from the first shift input unit is transmitted; a reverse input gear unit to which a reverse driving force from the first shift input unit is transmitted; a second shift input unit in which a second shift middle clutch is provided at one side end and a second shift low gear is installed to be constrained by a second shift one-way bearing in one direction so that a driving force from the first shift output unit is transmitted thereto; a forward idle gear unit connected to and installed at the first shift output unit and the second shift input unit to transmit a driving force from the first shift output unit to the second shift input unit; and a second shift output unit installed so that a reverse driving force by the reverse input gear unit and a forward driving force by the second shift input unit are transmitted thereto.
