A connector in a clutch connection structure used in an electrical automobile, which includes: a locking part formed at a body; a latch in contact with the locking part; a first solenoid driving part disposed on one side of the latch; and a second solenoid driving part disposed on the other side of the latch, in which the first solenoid driving part and the second solenoid driving part face each other with the latch being interposed therebetween, such that an operation of a clutch when the clutch operates becomes simple, and thus, noise, vibrations, and durability thereof are improved.

A coupling means having a first member provided with a first diaphragm and a second member provided with a second diaphragm. The coupling means include an additional device having a plurality of protrusions circumferentially distributed on a first cylinder of the first member and a plurality of abutments distributed circumferentially on a second cylinder of the second member, each protrusion presenting at least one sliding face facing a first bearing face of an abutment, each protrusion presenting a blocking face facing a face of the second member referred to as a second bearing face.

A driveline assembly for use with a well-servicing pump system is disclosed. The driveline assembly comprises a stub shaft attachable to one of a pump or a motor, a flange shaft attachable to the other of the pump or the motor, and a coupling assembly comprising a drive-transfer cylinder and a spring-loaded locking sleeve. In a drivingly-engaged position, rotary drive motion of the motor is transferred to the pump. In an unlocked position, the locking sleeve allows the drive-transfer cylinder to move axially from the drivingly-engaged position where the drive-transfer cylinder connects and transfers rotary drive between the flange shaft and the stub shaft to the drivingly-disengaged position where the drive-transfer sleeve disconnects and allows relative rotation between the flange shaft and the stub shaft. In a locked position, the locking sleeve locks the drive-transfer cylinder in one of either the drivingly-engaged position or the drivingly-disengaged position.

In some implementations, the device may include stationary and rotatable members. A locking element supported on the stationary member moves between an engaged, torque hold or transfer position where the locking element holds or transfers torque between the stationary member and the rotatable member and a disengaged, torque-free position where the locking element holds or transfers no torque between the stationary member and the rotatable member. The device may include a threaded shaft, with the locking element threadably received on the threaded shaft.

A gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a fan and a braking system. The braking system is configured to selectively engage the fan during ground windmilling to apply a first level of braking to slow rotation of the fan. Further, when the rotation of the fan sufficiently slows, the braking system is further configured to apply a second level of braking more restrictive than the first level of braking.

A clutch assembly having a first clutch member, a second clutch member axially slidable in a first axial direction to engage the first clutch member and in a second axial direction to disengage from the first clutch member, a spring biasing the second clutch member in one of the axial directions, a piston actuatable to move the second clutch member in the other of the axial directions, thereby overcoming a biasing force of the spring, and a latching device to selectively lock the piston in at least one of the first axial direction and second axial direction. The latching device includes a selectively retractable locking pin. The piston has an external surface defining a slot to receive the locking pin, thereby locking the piston in the first position or the second position. A method of operating the clutch assembly is provided.

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 power system for an aircraft comprises: a motor-generator component; a shaft, wherein the motor-generator component is connectable to the shaft, the shaft connectable to an additional component of the aircraft to for torque transfer with the additional component; and a de-coupler operable to disconnect the motor-generator component from the shaft, wherein the motor-generator component is located between the de-coupler and the additional component in use.

In at least some implementations, a disconnect assembly for a driveline component, such as a power transfer unit, may include an input shaft, a disconnect shaft selectively rotated by the input shaft and an output shaft coupled to the disconnect shaft. A first gear is coupled to the disconnect shaft and a second gear is coupled to the output shaft and to the first gear so that the output shaft rotates when the disconnect shaft rotates. A connection feature is movable between an engaged position in which the input shaft and disconnect shaft are coupled and a disengaged position in which the input shaft rotates relative to the disconnect shaft. The connection feature includes a first part carried by the gear for rotation therewith and a second part movable relative to the first part and carried by the input shaft for rotation with the input shaft.

The present disclosure relates to a laundry treatment machine. The laundry treatment machine according to an embodiment includes a coupling configured to transfer the driving force of a driving motor to the washing shaft or the dewatering shaft; a stopper engaged with the coupling and anchoring the dewatering shaft; a clutch motor configured to move the coupling; a ball stud protruding from the stopper toward the coupling and having a ball disposed at one end of the ball stud; and a clutch lever having a ball housing for receiving the ball of the ball stud and configured to move the coupling by the operation of the clutch motor.
