Abstract

The invention discloses a bicycle rear derailleur with a function of stabilizing a chain. The bicycle rear derailleur comprises a foundation support member, a movable member, a chain guide part connected to the movable member through a rotating shaft and a resistance applying component, wherein the resistance applying component comprises a friction applying member and a clutch assembly, the friction applying member applies friction resistance to the rotation of the clutch assembly so as to apply the friction resistance to the rotation of the chain guide part; the clutch assembly comprises a first clutch ring and a second clutch ring, the first clutch ring is connected with the rotating shaft in a torque transmission way and can move along the axis direction of the rotating shaft, the second clutch is provided with a cylindrical axial bulged part, and the friction applying member is installed on the outer circumference of the cylindrical bulge part of the second clutch ring and closely matched with the outer circumferential part of the cylindrical bulge so as to apply a friction force to the rotation motion of the second clutch ring.

Description

technical field [0001] This invention relates to derailleurs in bicycle shifting systems, and more particularly to rear derailleurs. Background technique [0002] A bicycle derailleur generally includes a shift lever or a shift grip mounted on the handlebar, a front derailleur mounted near the center shaft of the bicycle, and a rear derailleur mounted near the rear axle of the bicycle. For the rear derailleur, it usually includes: a base member, a movable member, a chain guide, etc., the movable member is movably coupled to the base member through a linkage mechanism, under the action of a control cable on the shift lever , so that the chain guide moves laterally relative to the base member to achieve the purpose of gear shifting. The chain guide of a rear derailleur is usually rotatably mounted on a movable member and is resiliently biased in a clockwise direction so that the chain guide is adjusted when the chain is adjusted from a larger diameter sprocket to a smaller di...
