Abstract

Une sphère (6) et une protubérance (45) sont disposées sur une surface usinée (44) d’un élément mobile (4) et sont distantes de 180° sur une circonférence prédéterminée ayant pour centre un arbre à charnière (3). La longueur de la protubérance (45) est supérieure au diamètre de la sphère (6). Les premières cavités d’engagement (24A, 24B) et les secondes cavités d’engagement (25A, 25B) sont formées sur une surface usinée (23) d’un second élément à charnière (2). Les premières cavités d’engagement (24A, 24B) sont distantes de 270° dans la direction circonférentielle de la circonférence prédéterminée. Les secondes cavités d’engagement (25A, 25B) sont distantes de 270° sur la circonférence prédéterminée. Les secondes cavités d’engagement (25A, 25B) sont distantes de 180° des premières cavités d’engagement (24A, 24B), respectivement. Une rigole de guidage (26) est formée entre les premières cavités d’engagement (24A, 24B), et la rigole de guidage (26) s’étend de la première cavité d’engagement (24A) jusqu’aux secondes cavités d’engagement (25A, 25B) et jusqu’à la première cavité d’engagement (25B). La profondeur de la rigole de guidage (26) est supérieure à la profondeur des secondes cavités d’engagement (25A, 25B).
