摘要： An adjusting mechanism is provided for a bicycle derailleur, which can adjust a position of a chain guide in an axial direction. The derailleur basically has a base member, a movable member with the chain guide and a linkage assembly. The adjustment mechanism is preferably operatively coupled between the movable member and the chain guide, or between the base member and the frame. The adjusting mechanism includes a first tubular portion, a second tubular portion, a biasing member and an adjustment member. The second tubular portion is arranged around the first tubular portion to move axially relative to the first tubular portion via the adjustment member. The biasing member is arranged to apply an urging force on the tubular portions. One of the tubular portions has a rigid non-compressible support projection arranged to selectively contact the other tubular portion when the tubular portions move relative to each.

摘要： A family of new bicycle shifting systems incorporate improved derailleur designs that are controlled by sealed hydraulic actuators. The shifting systems (i) a hydraulically-actuated, manually-powered front and rear derailleur shifting system, (ii) a hydraulically-actuated, power-assisted front and rear derailleur shifting system with manual control, and (iii) a hydraulically-actuated, power-assisted front and rear derailleur shifting system in which the shifting sequence for the rear derailleur is controlled automatically by pedal speed. Each of these shifting systems utilize a totally sealed, inclined linear shifting path. Environmental contaminants are prevented from entering any of the critical derailleur or control elements. The linear, inclined shifting path provides precise chain shifting, more uniform chain wrap on the rear bicycle drive sprockets, and lower chain and sprocket wear. Several different shifting control units are disclosed. An integrated shifting and braking module is also disclosed.

摘要： A bicycle derailleur for attachment to a bicycle frame includes a base member apparatus having a first projection and a coupling member for coupling the base member apparatus to the bicycle frame. A chain guide is coupled to the base member apparatus for movement relative to the base member apparatus and for guiding a chain among a plurality of sprockets. The first projection is adapted to rotate relative to a second projection formed on a second member facing the first projection when the base member apparatus is mounted to the bicycle, and a shock absorber is adapted to be disposed between the first projection and the second projection for absorbing shocks between the first projection and the second projection.

摘要： A bicycle front derailleur includes a frame bracket for fixing the derailleur to a bicycle frame, a cage plate for guiding a chain among a plurality of chainwheels, and a radial adjustment mechanism for adjusting a position of the cage plate substantially radially relative to the chainwheels. In a more specific embodiment, a derailleur bracket fixes the cage plate to the frame bracket, wherein the derailleur bracket defines a derailleur bracket opening. A bushing is disposed in the derailleur bracket opening. The bushing defines a bushing opening such that the bushing has an eccentric shape relative to the bushing opening. A fastener extends through the bushing opening for fastening the bushing to the frame bracket. Thus, rotation of the bushing varies the position of the derailleur bracket and hence the position of the cage plate relative to the chainwheels.

摘要： A derailleur serves to change the speed of a chain driven vehicle by moving a change-over frame having a tension and a guide pulley, the change-over frame being formed of a single plate and provided with a chain holder positioning radially outwardly of the guide pulley and keeping engagement of a driving chain therewith. Interaction between the change over frame and chain during the shifting of speed is substantially reduced. Chain position is maintained by means of a chain holder reducing chain interference with the change over frame. The chain may be removed with a minimum effort without special tools.
