Abstract

L'invention concerne un dispositif de freinage conçu pour un bicycle ou un tricycle pourvu de deux manettes de frein. Ce dispositif de freinage comprend un module d'accouplement (1) qui sert à actionner de manière synchronisée au moins un frein de roue avant et au moins un frein de roue arrière. Ce module d'accouplement (1) comprend un logement d'accouplement (2) dans lequel une pièce d'accouplement (5) est disposée de manière à pouvoir être déplacée. Cette pièce d'accouplement (5) se présente sous la forme d'un profilé en double T ou en H, à savoir elle comporte un élément transversal côté manette de frein (5a), un élément de liaison (5c), et un élément transversal côté frein (5b). Des passages sont ménagés dans l'élément transversal côté manette de frein (5a), pour laisser passer, sans frottement, des câbles de freinage côté manette de frein (6a, 6b), des serre-câbles (7a, 7b) étant disposés aux extrémités desdits câbles de freinage. Ces serre-câbles (7a, 7b) sont montés de manière à pouvoir être déplacés entre l'élément transversal côté manette de frein (5a) et l'élément transversal côté frein (5b). Les extrémités des câbles côté frein (11a, 11b) sont fixés sur l'élément transversal côté frein (5b). Le dispositif de freinage selon l'invention peut également être combiné à des dispositifs de freinage différents.
