A hybrid electric/combustion propulsion/electric generator apparatus comprising: a driven shaft mating mechanism; a hub mating mechanism; an electric machine operable as an electric motor or generator, comprising a rotor comprising a drum; a clutch mechanism, comprising first and second mating mechanisms, axially slidable and engaged with the drum/rotor; and a selection mechanism for sliding the clutch mechanism into a start position (wherein the electric motor can rotate the centrifugal clutch to rotate the driving shaft), a neutral position (wherein rotation of the drum/rotor operates the electric machine as the generator), or a drive position, wherein the apparatus is operable in either a pure electric drive mode (electric motor drives the driven shaft clockwise or counter clockwise while the centrifugal clutch is disengaged), or a hybrid drive mode (engine and electric motor drive the driven shaft) or a propulsion/generation mode (engine drives the driven shaft and generator produces electricity).

A reverse input blocking clutch includes an input member, an output member, a pressed member, and an engaging member. When a rotational torque is inputted to the input member, the engaging member moves in a direction away from a pressed surface of the pressed member due to engagement with the input member, and transmits the rotational torque inputted to the input member to the output member due to engagement with the output member; and when rotational torque is reversely inputted to the output member, moves in the direction closer to the pressed surface based on engagement with the output member, and by being pressed against the pressed surface does not transmit the rotational torque reversely inputted to the output member to the input member, or transmits only part thereof to the input member due to engagement with the input member.

An accessory drive tuning device with a torsion spring for angular vibration isolation and having a spring pocket that frictionally engages the end of the torsion spring. The engagement may be with a wedge-shape on either the spring end or the pocket or both, adapted so that the spring end wedges into the pocket. The engagement may be by interference fit. One or both ends of the spring may be engaged in respective pockets.

An object of the present invention is to provide a one-way clutch capable of preventing wear on radially inner engagement surfaces and radially outer engagement surfaces of cams in periods of high-speed freewheeling. The one-way clutch includes an inner race (110) and an outer race (150), a plurality of cams (140) provided between the inner race (110) and the outer race (150), and side plates (120, 130) provided to at least one of the inner race (110) and outer race (150) and positioned on both sides in an axial direction of the cams (140). The plurality of cams (140) are each configured to receive a predetermined centrifugal force to turn in an engaging direction in which the cams engage the inner race (110) and outer race (150) when the inner race (110) and outer race (150) rotate together in the same direction.

Provided is a centrifugal clutch configured so that a clutch capacity can be increased with a simple configuration. A centrifugal clutch 200 includes a drive plate 210 to be directly rotatably driven by drive force of an engine. The drive plate 210 includes each of swing support pins 214 and protruding bodies 218. The swing support pin 214 is fitted in a pin slide hole 231 formed at a clutch weight 230 to swingably support the clutch weight 230. The protruding body 218 is formed as a cylindrical roller. A driven portion 235 of the clutch weight 230 contacts the protruding body 218. The pin slide hole 231 is formed in a long hole shape allowing backward displacement of the clutch weight 230 in the rotary drive direction of the drive plate 210. The driven portion 235 is formed to extend inclined toward an outer rear side in a rotary drive direction of the drive plate 210.

Aspects of the technology relate to a braking assembly for a lateral propulsion system of a high altitude platform (HAP) configured to operate in the stratosphere. Power is supplied to a propeller assembly as needed during lateral propulsion so that the HAP can move to a desired location or remain on station. When lateral propulsion is not needed, power is no longer supplied to the propeller assembly and it may slowly cease rotating. However, in certain situations, it may be necessary to cause the propeller assembly to stop rotating as soon as possible. This can include an unplanned descent. Rapid braking can avoid the propeller blades from entangling in the envelope, parachute or other parts of the HAP. A reusable brake is employed to prevent uncontrolled rotation of the propeller on descent, or otherwise to prevent the propeller from spinning freely when not being used to propel the HAP laterally.

A clutch for an in-wheel motor includes a hub bearing coupled to a driving wheel and integrally rotated therewith, and formed in a cylindrical shape to provide a seating space therein; a drive shaft positioned in the seating space in a state of being spaced apart from an inner circumferential surface of the hub bearing, connected to a driving part to be rotated by rotational force of the driving part, and provided with a contact part on an outer circumferential surface of a first end of the drive shaft extended in a longitudinal direction; and a plurality of linings positioned inside the seating space on an outer side of the contact part and coupled to the hub bearing to be movable in a circumferential direction.
