The invention concerns an axle, comprising two arms (4A, 4B) articulated on a vehicle body, provided each with a wheel-bearing steering knuckle (5A, 5B) and connected by at least one crosspiece (3), wherein the link provided between the two arms by the crosspiece comprises at least an insert (2) defined by an elastomeric element (21), positioned, shaped and arranged to ensure at least partly a torsional reaction torque to the oscillations of an arm relative to the other. The invention is characterised in that the insert further comprises at least a bearing (22) for maintaining at an angle each of the two arms relative to the crosspiece, while allowing a rotation due to the oscillation of the arms, rotation to which the elastomeric element (21) responds with a torsional reaction.
