A clutch mechanism includes a transmission shaft, driven by an output shaft of a motive power device; a clutch element, including an engagement end, in unidirectional transmission connection with the transmission shaft, and a meshing end; a push rod, passing through the clutch element and including a contact end and a fixed end connected to the transmission shaft; a gear shaft, including a transmission gear in transmission connection with the meshing end; a rotary element, surrounding the gear shaft in a rotatable fashion and including a transmission end and a drive end; and a restoring element, one end bearing against the transmission shaft and another end bearing against the output shaft; and a drive gear, in transmission connection with the gear shaft and provided in a circumferential direction with a drive portion capable of pushing the transmission end. A gas insulated circuit breaker including clutch mechanism is also disclosed.

A pedaled drivetrain includes a drive mechanism, a wheel, a freewheel hub, and a locking mechanism. The wheel has a rotational axis. The freewheel hub connects the drive mechanism to the wheel, and the freewheel hub transmits torque from the drive mechanism to the wheel in a first rotational direction around the rotational axis. The locking mechanism has a locked state and an unlocked state. The locked state rotationally fixes a component of the drive mechanism to the wheel relative to the rotational axis.

A power transmitting apparatus comprising a clutch housing, an input member connected to an engine and mounted thereon, driving-side clutch discs, a clutch member connected to an output member, driven-side clutch discs arranged between the driving-side clutch discs, a pressure member for press-contacting the driving-side clutch discs and the driven-side clutch discs together and for releasing the press-contacting force on them, and a starter, such as a kick-starter, able to apply a rotational force to the output member to start the engine, the power transmitting apparatus adapted to transmit or cut off driving power of the engine inputted to the input member to or from the output member. The power transmitting apparatus can comprise a press-contact assisting cam of an inverse-driving side for increasing the press-contacting force on the driving-side clutch discs and the driven-side clutch discs when rotational force is applied to the output member by the kick starter.

A clutch mechanism for an energy storage device is disclosed. In an embodiment, the clutch mechanism includes a loading gear, a driving gear, a one-way bearing, a sleeve, and a gear shaft comprising a gear portion and a clutch portion. The gear shaft includes multiple spheres, and a push rod and an elastic element which are located in a cavity of the gear shaft. The push rod includes a groove and can slide in the axial direction of the gear shaft. A pressure block is fixed to the driving gear, the pressure block being able to push the push rod to slide in the axial direction of the gear shaft, so as to unlock or lock the sleeve and the gear shaft. A gas insulated circuit breaker employing such a clutch mechanism is also disclosed.

The present application relates to a clutch mechanism for an energy storage device including a load gear, a drive gear, a one-way bearing, a bushing, and a gear shaft including a gear portion and a clutch portion. The gear shaft includes multiple cylinders, and a push rod, a rotary sleeve and an elastic element located in a cavity of the gear shaft. The push rod includes a push rod slide hole and a push rod connecting hole, for connecting to the gear shaft and the rotary sleeve, respectively. A press block is fixed to the drive gear, the press block being capable of pushing the push rod to slide axially, so as to unlock or lock the bushing and the gear shaft. A gas insulated circuit breaker using such a clutch mechanism is also disclosed.

A multi-plate friction clutch wherein lubrication sites of the clutch can be efficiently supplied with oil to be sufficiently lubricated. A multi-plate friction clutch includes a clutch outer, a clutch center, clutch plates, and a pressure plate. A center ring protrusion protruding into a cylindrical shape from the outer surface of a center bottom wall part is formed at substantially the same radial position as a plurality of communication holes. Furthermore, a ring recess opened toward the axial center is formed in the inner circumferential surface of the center ring protrusion and the communication holes are so opened as to face the ring recess.

This clutch control apparatus includes a clutch apparatus, a clutch actuator, and a release mechanism, wherein the release mechanism includes a release shaft that transmits a drive force of the clutch actuator to the clutch apparatus side, the release shaft is divided into: a clutch-side shaft that is supported by a clutch-side member as a separate body from the clutch actuator; and a control-side shaft that is supported by the clutch actuator and is attachable to and detachable from the clutch-side shaft, and the clutch actuator configures an integral actuator unit that includes the control-side shaft.
