(54)Vehicle suspension axle with differentiated deformability


(57) A suspension axle for vehicles consists of a differentiated-deformability beam (11), preferably with an arched profile, designed to support, by means of hubs of a usual kind, the wheels (R1,R2) at its ends and carrying, in a substantially central position, an anchoring means consisting of an appropriate ball-and-socket joint (15) for anchorage to the body of the vehicle. Anchorage of the axle to the body is completed by two connecting rods (23a,23b), preferably in the form of substantially longitudinal strips connected to the body and to the axle. The transverse part of the beam has an overall torsional rigidity such as to enable a differential rebound of the wheels in order to ensure a behaviour of the suspension intermediate between that of a beam-axle suspension and that of a trailing-arm suspension.
