Title (EN) MOTOR VEHICLE FLEXIBLE AXLE, COMPRISING A CROSS BRACING WITH OPEN CROSS-SECTION WHEREOF THE FLANKS INCLUDE RECTILINEAR EDGES, CROSS BRACING AND CORRESPONDING MOTOR VEHICLE
(FR) ESSIEU SOUPLE DE VEHICULE AUTOMOBILE, COMPRENANT UNE TRAVERSE A SECTION OUVERTE DONT LES FLANCS PRESENTENT DES CHANTS NON RECTILIGNES, TRAVERSE ET VEHICULE CORRESPONDANT
Abstract:
(EN) The invention concerns a motor vehicle flexible axle comprising two longitudinal arms (20) connected by a cross bracing (10) with open cross-section whereof the flanks (11), (21) have each an edge (1), (2) extending between docking zones (4) with the ends of said cross bracing. The invention is characterized in that said edges (1), (2) have a non-rectilinear shape enhancing their tensioning when said cross member is subjected to torsion, said tensioning enabling said docking zones (4) to be relieved of stresses due to said torsion.
(FR) L'invention a pour objet un essieu souple de véhicule automobile comprenant deux bras longitudinaux (20) reliés par une traverse (10) à section ouverte dont les flancs (11), (21) présentent chacun un chant (1), (2) s’étendant entre des zones d'accostage (4) aux extrémités de ladite traverse, caractérisée ce que lesdits chants (1), (2) présentent une forme non rectiligne favorisant leur mise en tension lors d'une torsion de ladite traverse, ladite mise en tension étant de nature à soulager lesdites zones d'accostage (4) des contraintes dues à ladite torsion.
