Abstract

L’invention concerne un amortisseur de torsion (100) pour un groupe motopropulseur de véhicule, l’amortisseur de torsion (100) comprenant : - deux rondelles latérales (11, 12), à savoir une première rondelle latérale (11) et une deuxième rondelle latérale (12) aptes à tourner autour d’un axe de rotation X et solidaires en rotation l’une de l’autre par rapport à l’axe de rotation X, - un disque intérieur (21) agencé entièrement ou partiellement dans un espace délimité axialement par les deux rondelles latérales (11, 12), - une pluralité d’organes élastiques (30) disposés de manière à se déformer lors d’une rotation relative; selon l’axe de rotation X, entre les deux rondelles latérales (11, 12) et le disque intérieur (21) en exerçant un effort de rappel élastique apte à ramener les deux rondelles latérales (11, 12) et le disque intérieur (21) dans une position relative de repos, - une rondelle intermédiaire (41) étant apte à tourner selon l’axe X par rapport au disque intérieur (21) et par rapport à la première rondelle latérale (11), - un organe d’arrêt (19) comprenant un élément de butée (52) coopérant avec le disque intérieur et une portion de contournement (16) de la rondelle intermédiaire (41). Figure pour l’abrégé : Figure 1The invention relates to a torsion damper (100) for a vehicle power train, the torsion damper (100) comprising: - two side washers (11, 12), namely a first side washer (11) and a second lateral washer (12) capable of rotating about an axis of rotation X and integral in rotation with one another with respect to the axis of rotation X, - an internal disc (21) arranged entirely or partially in a space delimited axially by the two lateral washers (11, 12), - a plurality of elastic members (30) arranged so as to deform during relative rotation; along the axis of rotation X, between the two side washers (11, 12) and the inner disc (21) by exerting an elastic return force capable of bringing back the two side washers (11, 12) and the inner disc (21) ) in a relative rest position, - an intermediate washer (41) being able to rotate along the X axis with respect to the inner disc (21) and with respect to the first lateral washer (11), - a stop member (19) comprising a stop element (52) cooperating with the inner disc and a bypass portion (16) of the intermediate washer (41).
