Abstract

L'invention concerne un raccord rotatif (1) pourvu d'un palier à roulement (2), comprenant une bague de palier extérieure (3), une bague de palier intérieure (4) et des corps roulants logés entre ces deux bagues. Pour produire une action de freinage par friction, une plaque d'ancrage (9), mobile axialement, reliée à une des bagues de palier (4) est plaquée contre une plaque de pression (23) reliée à l'autre bague de palier (3) et la liaison de friction peut être rompue au moyen d'un électroaimant, le raccord rotatif (1) présentant un dispositif de guidage pour la plaque d'ancrage (9). Selon l'invention, le dispositif de guidage présente plusieurs ressorts plats (18) qui sont répartis sur la circonférence et qui sont reliés d'un côté à la plaque d'ancrage (9) et de l'autre côté à la bague de palier (4) reliée à la plaque d'ancrage (9).
