Flexible axle comprising a cross-member having one or more zones of reduced rigidity in torsion, passes through the production and the corresponding vehicle

摘要

The invention relates to a flexible axle for motor vehicle, comprising a cross-member (2) connecting the two longitudinal arms (1), characterized in that said cross-member (2) has, at least three zones (21), (22) with different rigidities in torsion, at least one intermediate zone (22) having a first torsional rigidity and at least two end zones (21), located in the vicinity of each of the ends of said cross-member and each having a second torsional rigidity less than said first torsional rigidity, said end zones acting at least when the ends of said cross-member are subjected to torsional stresses antagonistic.
