Abstract
A cogset with a plurality of sprockets has a subset of the sprockets connected together in a monolithic subset that is mounted directly in engagement with a coupling profile on the radially peripheral surface of a sprocket in the monolithic subset. The direct shape coupling between the sprocket of the monolithic subset and the sprocket-carrying body makes it possible to have very high solidity and rigidity of coupling to ensure the maximum precision of actuation of the gearshift that uses the sub-assembly.
Claims15
A cogset for a bicycle rear wheel, the cogset comprising a plurality of adjacent sprockets adapted for being mounted coaxially on a sprocket-carrying body, the plurality of adjacent sprockets numbering between 12 and 14 sprockets where a first sprocket has a minimum number of teeth and a last sprocket has a maximum number of teeth, wherein “n” sprockets from the plurality of sprockets are fixedly connected together in a monolithic set, where the range of “n” is 6≥n≥3, and the monolithic set is adapted for direct engagement on a coupling profile formed on a radially peripheral surface of a sprocket-carrying body through a coupling profile formed on a radially inner surface of at least the largest sprocket of the monolithic set.
A sub-assembly for a bicycle rear wheel, the sub-assembly comprising a sprocket-carrying body and a cogset mounted coaxially on the sprocket-carrying body, wherein the cogset comprises a plurality of 12 to 14 axially adjacent sprockets between a first sprocket having a minimum number of teeth and a last sprocket having a maximum number of teeth, wherein the sprockets are mounted coaxially on a sprocket-carrying body, wherein “n” sprockets of the plurality of axially adjacent sprockets, where “n” is 6≥n≥3, are fixedly connected in a monolithic set, and wherein the monolithic set is directly engaged on a coupling profile formed on a radially peripheral surface of the sprocket-carrying body through a coupling profile of the monolithic set.
A cogset for a bicycle rear wheel, the cogset comprising at least 12 and no more than 14 sprockets adapted for being mounted coaxially on a sprocket-carrying body, where a first sprocket has a minimum number of teeth and a last sprocket has a maximum number of teeth, and “n” sprockets are fixed together in a monolithic set that includes the first sprocket, where “n” is in the range of 6≥n≥3, and the monolithic set is adapted for direct engagement on a coupling profile formed on a radially peripheral surface of a sprocket-carrying body through a coupling profile formed on a radially inner surface of at least a largest sprocket in the monolithic set.
