The twist-beam axle ( 10 ) comprises a central cross-member ( 11 ) compliant to torsion and a pair of trailing arms ( 12 ) fixed to side end portions ( 11 a) of the cross-member ( 11 ) for articulated connection of the axle to the vehicle body and for support of the rear wheels. Each trailing arm ( 12 ) is formed by a pair of first, transversely inner half-shells ( 18, 19 ), that is, a front half-shell and a rear half-shell, respectively, securely connected to each other and to the respective end ( 11 a) of the cross-member ( 11 ), and by a second transversely outer half-shell ( 20 ), securely connected to the pair of first half-shells ( 18, 19 ) so as to form therewith a structure having a closed cross-section. |
