Abstract

Dispositif de centrage pour ensembles munis de deux éléments tournant mutuellement en sens inverse comportant un ressort (1) à barre de torsion, dont la région de torsion centrale (2) possède une coupe réduite. Des régions de support (3, 4) sont prévues aux extrémités des ressorts (1) à barre de torsion sur lesquels sont fixés des éléments de liaison (5, 6) pour connecter le dispositif de centrage avec les deux éléments de l'ensemble. Les éléments de liaison (5, 6) comportent des prolongements (9, 10) en forme de manchon, qui entourent sans contact les ressorts à barre de torsion dans leur zone de torsion (2). Un soufflet métallique (11) résistant à la torsion et ayant un effet de ressort axial est connecté en parallèle au ressort (1) à barre de torsion, ledit soufflet métallique étant disposé coaxialement par rapport au ressort (1) à barre de torsion. Le soufflet métallique (11) est relié à une de ses extrémités avec le prolongement (9) en forme de manchon d'un des éléments de liaison (5). A son autre extrémité le soufflet métallique (11) est relié avec une première pièce de centrage (12) d'un dispositif de blocage (13) dans une position centrale. Une deuxième pièce de centrage (14) du dispositif de blocage (13) dans la position centrale est reliée au prolongement (10) en forme de manchon de l'autre élément de liaison (10).
