Title (EN) METHOD FOR MANUFACTURING A COMPOSITE TWIST-BEAM AXLE FOR A REAR SUSPENSION OF A VEHICLE
(FR) PROCÉDÉ POUR FABRIQUER UN ESSIEU À POUTRE DE TORSION COMPOSITE POUR UNE SUSPENSION ARRIÈRE D'UN VÉHICULE
Abstract:
(EN) The twist-beam axle (10) comprises a cross-member (12) and a pair of trailing arms (14) of metal, each firmly connected to a respective end of the cross-member (12). The cross- member (12) has a hybrid structure with a central element (22) of composite material with a resin matrix reinforced with fibres and with a pair of lateral elements (24) of metal firmly connected to the central element (22). Once the cross-member (12) is manufactured, with the central element (22) and the two lateral elements (24) firmly connected to the central element (22), each trailing arm (24) is welded to a respective lateral element (24) of the cross-member (12).
(FR) Selon l'invention, un essieu à poutre de torsion (10) comprend une traverse (12) et une paire de bras arrière (14) en métal, chacun étant fermement relié à une extrémité respective de la traverse (12). La traverse (12) a une structure hybride avec un élément central (22) en matériau composite avec une matrice de résine renforcée par des fibres et avec une paire d'éléments latéraux (24) en métal fermement reliés à l'élément central (22). Une fois que la traverse (12) est fabriquée, avec l'élément central (22) et les deux éléments latéraux (24) fermement reliés à l'élément central (22), chaque bras arrière (24) est soudé à un élément latéral respectif (24) de la traverse (12).
