Abstract:
A sliding component comprises a base member, a plated layer, and a lubricant agent. The plated layer includes a metallic material and is disposed on the base member. The lubricant agent includes a fatty acid containing a carboxyl group. The lubricant agent contacts the plated layer.
Abstract:
Provided is a vehicle speed-change system including the following: a transmission positioned to the rear of a crank shaft of an engine; a transmission case that retains the transmission; a shift mechanism that has a shift cam which performs a speed-change operation of the transmission; and a shift actuator that operates the shift cam. The transmission includes a counter shaft positioned to the rear of the crank shaft, and a drive shaft to which rotation of the counter shaft is transmitted. The shift cam is positioned further to the rear than the counter shaft, and the shift actuator is arranged in a rear portion of the transmission case and to the rear of the shift cam.
Abstract:
A gear selector actuator (1) is provided with an electric linear drive that is accommodated in a housing (2) that is closed on an axial side by a cover (3) that has an opening (4) for an actuation element. The actuation element is held on the cover (3) and the housing (2) has a cap (5) covering an installation opening of the housing and securing the actuation element.
Abstract:
A bicycle control cable is provided with a central wire and at least one resin string. The at least one string made of resin is spirally wound onto the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire with a pitch less than or equal to 1 millimeter. The at least one resin string defines a spiral gap between adjacent windings of the at least one resin string. The at least one resin string defines an outer sliding surface for reducing a sliding resistance of the central wire. The central wire and the at least one resin string define an inner wire configured to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case to operate a bicycle component.
Abstract:
A hub transmission for a bicycle comprises a hub axle; a driver rotatably supported to the hub axle; a hub shell rotatably supported to the hub axle; a power transmitting mechanism disposed between the driver and the hub shell for communicating rotational power from the driver to the hub shell through a plurality of power transmission paths; a shift mechanism for selecting the plurality of power transmission paths; a shift assist mechanism for communicating rotational power from the driver to the shift mechanism; and a power control mechanism disposed between the driver and the shift assist mechanism and coupling rotational power from the driver to the shift assist mechanism for communicating non-constant rotational power from the driver to the shift assist mechanism.
Abstract:
The described actuation device comprises a casing, intended for the attachment to the handlebar of the bicycle, a cable-winding bobbin, angularly mobile in the casing about a main axis of the device, a first driving mechanism, acting on the bobbin to rotate it in a first angular direction, a second driving mechanism, acting on the bobbin to rotate it in a second angular direction opposite the first, as well as indexer assembly for removably holding the bobbin in predetermined angular positions. In accordance with the invention, the indexer assembly comprise first countering member, to counter the rotation of the bobbin in the first direction, and second countering member, distinct from the first countering member, to counter the rotation of the bobbin in the second direction. Asymmetric operation is thus obtained which allows active actuation to be set both for upward gearshifting and for downward gearshifting.
Abstract:
A cable connecting apparatus includes a cable sleeve adapted to receive the outer casing of a control cable; a guide having a first end portion and a second end portion for movably supporting the cable sleeve; and a biasing device for biasing the cable sleeve toward the second end portion of the guide. In another device, a connecting member is provided for connecting a portion of a first inner wire located between a first outer casing and a second outer casing to a portion of a second inner wire disposed between a third outer casing and a fourth outer casing, wherein the connector moves together with the first inner wire and the second inner wire. A position confirmation means allows the position of at least one of the first outer casing, the second outer casing, the third outer casing and the fourth outer casing to be visually confirmed.
Abstract:
An internal hub transmission for a bicycle includes a hub axle having an axle axis for retaining the transmission to a bicycle frame, a driver rotatably supported relative to the hub axle, an output member rotatably supported relative to the hub axle, a power transmission mechanism disposed between the driver and the output member for communicating rotational force of the driver to the output member through a plurality of transmission paths, and an operation mechanism disposed in the hub axle for movement in the direction of the axle axis to select among the plurality of transmission paths. An actuating mechanism is mounted on the hub axle inboard of a free end of the hub axle for moving the operation mechanism in the direction of the axle axis.
Abstract:
A casing for accommodating an operating pull for the purpose of attaching the operating pull to a bicycle gear, especially to a multiple-gear hub with a shifting wheel. The shifting wheel is placed, coaxially to the hub axis, at one of the ends of the hub. The shifting wheel is in contact with a control device that can be operated by the bicyclist during operation of the bicycle. The control device can include a remote-handling device that can be used by the bicyclist. The remote-handling device has a cable pull and a cable cover. The cable cover supports itself on the casing extension by an adjusting screw. The casing has a drive casing, for covering the shifting wheel, and a tubular casing extension, for accommodating the cable pull and an operating pull. The drive casing is connected to the casing extension by a joint with a cable guide. A spring storage and a coupling can be accommodated in the casing extension.
