The engagement member includes a first engagement structure for engaging a corresponding engagement structure associated with the engine shaft for setting the clutch arrangement in a propeller propulsion mode, in which rotational propulsion torque is transmitted from the engine shaft to the propeller shaft via the engagement member. The engagement member further includes a second engagement structure for engaging a corresponding engagement structure associated with the clutch arrangement housing for setting the clutch arrangement in a propeller locked mode, in which the propeller shaft is rotationally locked to the clutch arrangement housing by means of the engagement member.

A gas turbine engine has an engine static structure and at least one component rotatable relative to the engine static structure about an engine axis of rotation. A fan is coupled to at least one component for rotation about the engine axis of rotation. An actuator is mounted to the engine static structure, wherein the actuator is activated to prevent the fan from rotation and is inactivated to allow the fan to rotate. A method for preventing rotation of a fan in a gas turbine engine is also disclosed.

Coupling mechanisms for torque transmitting shafts are provided with sliding and fixed plates operably connectable to respective torque transmitting shafts, and a leaf spring having a preloaded spring force exerted on the sliding plate when the sliding and fixed plates are operably connected to one another. A hub is attached to the leaf spring and coaxially received within the sliding plate to allow the sliding plate to be capable of reciprocal axial movements relative to the hub between engaged and disengaged positions wherein the sliding and fixed plates are engaged and disengaged with one another so as to allow and prevent torque being transmitted from one to another of the shafts, respectively. An inner piston is coaxially received within the hub and moveable between a first position wherein the hub retains the sliding plate in the engaged position thereof, and a second position wherein the hub releases the sliding plate to allow movement of the sliding plate under bias force from the leaf spring into the disengaged position thereof.

A locking mechanism for locking a driveshaft in cooperative engagement with an apparatus includes a drive portion coupled to the driveshaft and a driven portion coupled to the apparatus. The drive portion of the locking mechanism includes a housing with a first engagement portion, a ball cage with a plurality locking balls contained at least partially therein, and a chock biased away from the housing by a chock spring. The chock includes an outer wall configured to push the locking balls outward in a locked position and allow inward movement in an unlocked position. Movement of the chock, and therefore locking, is controlled by an actuator rod extending through a center of the locking mechanism. The driven portion includes a second engagement portion configured to cooperatively engage and receive torque from the first engagement portion, and a locking groove configured to receive a portion of each of the plurality of locking balls therein.

A drive wheel clutch system for manually disengaging one or more drive wheels from their driveshafts. The drive wheel clutch system generally includes a driveshaft, a flange at one end of the driveshaft, and a flange-engaging member. The flange-engaging member and the flange may be generally disc shaped. The flange-engaging member is spring loaded and includes locking members that can extend through apertures in the flange to engage with locking apertures in the hub of a drive wheel. An operator can pull against spring bias and rotate a handle connected to the flange-engaging member to disengage the locking members from the flange and the hub, allowing the wheel to turn freely while the driveshaft remains stationary.

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.

An axle disconnect apparatus having a cam cylinder including a ramp disposed in a radially outer surface thereof. A first clutch element disposed at least partially inside the cam cylinder and an intermediate shaft disposed at least partially within the first clutch element. The intermediate shaft includes a splined portion in constant mesh with the first clutch element. A half shaft may be disposed coaxially with the intermediate shaft, and a second clutch element may be coupled with the half shaft. The first clutch element selectively engages the second clutch element. The axle disconnect apparatus further comprises a latching mechanism whereby the cam cylinder maintains an axial position. The latching mechanism including a radial depression in the cam cylinder ramp, and a cam follower selectively disposed at least partially in the radial depression.

The vehicle drive device includes the clutch being provided between the speed reducing mechanism and the differential device, and configured to be rotated integrally with the differential device, and moved in the rotation axis direction to engage with or release from the speed reducing mechanism, and the solenoid pin capable of contacting with and separating from the outer peripheral surface of the clutch, the guide groove is formed on the outer peripheral surface of the clutch so as to intersect in the rotation direction of the clutch, and the solenoid pin contacts the guide groove to thereby move the clutch.

Methods and systems are provided for an electromagnetic pulse disconnect assembly. In one example, an electromagnetic disconnect assembly includes an electromagnetic coil assembly including an electromagnetic coil, an armature cam including an annular ring and a plurality of bidirectional cam ramps extending in an axial direction from the annular ring, where the annular ring is adapted to have face-sharing contact with the electromagnetic coil assembly when the electromagnetic coil is energized and be spaced apart from the electromagnetic coil assembly when the electromagnetic coil is de-energized, and a cam follower a plurality of radially extending guides arranged around a circumference of the cam follower and spaced apart from one another via a plurality of elongate apertures, each of the plurality of elongate apertures adapted to receive one of the plurality of bidirectional ramps of the armature cam. The assembly may further include a latching system.

A rotating shaft connection apparatus and a multi-screen mobile terminal device are related to. The rotating shaft connection apparatus includes a rotating shaft, a drive member, an adapting member, and a magnetic member. The drive member is fixed on the rotating shaft; the adapting member and the magnetic member are rotatably sleeved on the rotating shaft; the adapting member is located between the drive member and the magnetic member; and the adapting member is slidably engaged with the rotating shaft in an axial direction. In a first state, the adapting member is engaged with the drive member in a locking manner, and the rotating shaft is rotated so as to rotate the adapting member; and in a second state, the rotating shaft stops rotating, and the adapting member is engaged with the magnetic member in a locking manner.
