Abstract

Le dispositif comprend une partie mobile équipée d'une structure mécanique, ladite partie mobile étant apte à effectuer un mouvement de rotation par rapport à une partie fixe par l'intermédiaire d'un roulement (1), ledit enroulement comportant un élément fixe (12) relié à la partie fixe (20) et un élément mobile (23) entraîné en rotation par un pignon d'attaque (5) lui-même entraîné par un moteur (3). La partie mobile (10) comporte au moins : - un moyeu (21), fixe par rapport à l'élément mobile (23) du roulement (1) ; - une jante (22), supportant la structure mécanique, solidaire mécaniquement du moyeu (21) par l'intermédiaire d'au moins un patin de frottement (C') serré entre le moyeu et la jante ; la jante (22) ayant un mouvement de glissement en rotation par rapport au moyeu (21) lorsqu'elle est soumise à un effort de cisaillement supérieur à une force de glissement (F ) fonction de l'effort de serrage appliqué sur le patin de frottement.The device comprises a movable part equipped with a mechanical structure, said movable part being able to perform a rotational movement relative to a fixed part by means of a bearing (1), said winding comprising a fixed element (12 ) connected to the fixed part (20) and a movable element (23) driven in rotation by a pinion gear (5) itself driven by a motor (3). The movable part (10) comprises at least: - a hub (21), fixed relative to the movable element (23) of the bearing (1); - a rim (22), supporting the mechanical structure, mechanically secured to the hub (21) by means of at least one friction pad (C ') clamped between the hub and the rim; the rim (22) having a sliding movement in rotation with respect to the hub (21) when it is subjected to a shear force greater than a sliding force (F) which is a function of the clamping force applied to the brake pad friction.
