MOTOR VEHICLE FLEXIBLE AXLE, COMPRISING A CROSS BRACING WITH OPEN CROSS-SECTION WHEREOF THE FLANKS INCLUDE RECTILINEAR EDGES, CROSS BRACING AND CORRESPONDING MOTOR VEHICLE

摘要

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.
