Abstract: A bicycle derailleur includes following features. A chain guiding portion is adapted to be engaged with a bicycle chain and is adapted to guide a drive direction of the bicycle chain. A connecting portion is connected to a fixed portion and the chain guiding portion. A movable portion is pivotally connected to the connecting portion and the chain guiding portion. The movable portion includes a pressing member, a base, and a sprag clutch. The sprag clutch is disposed between the pressing member and the base. The pivot shaft is connected to the movable portion and the chain guiding portion, and is rotatably disposed through the pressing member, the sprag clutch and the base. The sprag clutch is driven to rotate when the pivot shaft rotates along the direction. The pressing member is adapted to press the sprag clutch to increase rotational resistance of the chain guiding portion.

Abstract: An object of the present invention is to provide a cam and a one-way cam clutch that realize a reduction in weight and production cost, provide more design freedom in setting the center of gravity of the cam, and achieve high responsiveness. The above object is achieved by a cam configured to make contact with an inner race and an outer race by a rotational moment applied in an engaged direction by an annular spring, in which a plurality of cam plates having an identical outer contour and arranged in parallel along a direction of the pivot axis are coupled together and united by a connecting pin extending in the direction of the pivot axis, and the annular spring is configured to be mountable between adjacent cam plates and/or on an outer side of the plurality of cam plates in the direction of the pivot axis.

Abstract: A cage freewheel for installation into the clamping gap of a shaft/hub connection, in particular in an e-bike drive, includes an annular cage with, following one another in the circumferential direction, bearing rollers for mounting the hub and the shaft together, and clamping bodies arranged pivotably in the cage. The clamping bodies block a relative movement between the shaft and the hub in a frictionally locking manner in one rotational direction, and allow rotation in the other rotational direction, and are spring-loaded in the coupling direction by an annular spring which extends around the row of the clamping bodies in a slot in the radially outer surface of the clamping bodies. The bearing rollers are arranged in each case in pairs in associated pockets of the cage on both sides of the annular spring. Here, the bearing rollers are received in a positively locking manner in the associated pockets.

Abstract: A drive system includes an inner race member and an outer race member. A first disengageable sprag clutch is disposed between the inner race member and the outer race member, the first disengageable sprag clutch having a drive direction and a freewheeling direction. A second disengageable sprag clutch is disposed between the inner race member and the outer race member, the second disengageable sprag clutch having a drive direction and a freewheeling direction that are opposite the drive direction and the freewheeling direction of the first disengageable sprag clutch.

Abstract: A bicycle hub apparatus may comprise a wheel hub, a hub body for installing a sprocket, and a one-way bearing unit positioned between the wheel hub and the hub body. A connecting housing is formed at a lateral end of the wheel hub, and a shaft axially protrudes from a central portion of the connecting housing. A driving ring made of high-strength material is securely positioned in the connecting housing, and a driving surface is formed on an inner periphery of the driving ring. The hub body adapted to connect to the wheel hub comprises a gear sleeve and a driving sleeve which are made of high-strength material to make the bicycle hub apparatus lightweight and prevent the wheel hub and the hub body from worn by the bearing unit, thereby improving transmission efficiency.

Abstract: A drivetrain subassembly includes a clutch portion and a gear shaft portion connected by an integrated inner race/gear shaft member. The clutch portion includes a sprag clutch configured to transfer torque from an engine to a rotor system while allowing the rotor system to continue to rotate in the event of an engine failure. The inner race of the clutch portion is integrally formed with the gear shaft of the gear shaft portion of the subassembly. The gear shaft is configured to rotate about the longitudinal axis of the sprag clutch for transmitting torque from the sprag clutch to a downstream drivetrain component.

Abstract: A magnetically hinged, overrunning clutch is disclosed. Sprags containing rare-earth permanent magnets, and arranged in pairs of opposite magnetic orientation, are located within the gap between the inner surface of a hollow, circularly cylindrical shaft and the external surface of a smaller diameter, second circularly cylindrical shaft. Pairs of rare-earth permanent magnets encircling the second cylindrical shaft are located at, or just beneath, the surface of the shaft and are arranged in pairs having alternating magnetic orientation. The sprags are cylinders having a pseudo-spiral cross-section and are sized, and the ferromagnetic region located, such that when the sprags are attracted to the shaft-magnets, the first shaft may be rotated with respect to the second shaft in a first, overrunning direction of rotation, but the first shaft does not rotate with respect to the second shaft in an opposite, or lock-up direction.

Abstract: To provide a cam clutch including an outer ring, an inner ring provided inside of the outer ring, a plurality of cams inserted between the outer ring and the inner ring, and an annular spring. A line connecting a first abutment portion between the outer ring and each of the cams and a second abutment portion between the inner ring and the cam and a line passing the second abutment portion form an angle in a state with the cams engaging with the outer ring and the inner ring. Rotation of the outer ring and the inner ring is enabled in the respective one directions while rotation thereof is restricted in the respective other directions. A groove is formed on an inner periphery of the outer ring or an outer periphery of the inner ring.

Abstract: A supercharger system includes an impeller, a compressor housing, an input shaft, an input pulley assembly, and a freewheel clutch. The impeller is for acquiring air. The compressor housing surrounds at least a portion of the impeller so as to direct the acquired air toward an internal combustion engine. The input shaft is configured to rotate the impeller. The input pulley assembly is configured to drive the input shaft and interface with a serpentine belt that is associated with the power source. The input pulley is configured to rotate in a primary direction correlating with rotation of the serpentine belt in the primary direction. The freewheel clutch is configured to interface with an input shaft of the supercharger, wherein the freewheel clutch prevents rotation in a reverse direction that is opposite the primary direction.

Abstract: A steering device includes a steering column, a bracket, and a fixing mechanism. The fixing mechanism includes a roller clutch, an inner ring, a slip ring and a rod which penetrates through side plate portions of the bracket. The roller clutch and the inner ring are not operated in a clamping direction in which the manipulation lever is rotated to provide a clamping force and are operated in a releasing direction in which the manipulation lever is rotated to release the clamping force. The slip ring is a friction providing member which applies frictional resistance to the rod in a case where the roller clutch and the inner ring are operated.
