The invention relates to a rubber auxiliary suspension with stages under tension for vehicle axles in general, comprising a pair of outer and inner concentric tubes with rubber adhered to the contact surfaces thereof. The rubber is subjected to tensile loads by the tubes when one of said tubes is rotated inside the other. The inventive system can comprise two integrated stages or take the form of a hybrid. Said suspension connects the vehicle chassis with the axle of the wheels by means of a lever arm, which is soldered to the outer tube, and a support, which holds the inner tube and the tension control system thereof at the other end. The invention is characterised in that it comprises, among other elements, (i) a tension lever which converts the longitudinal movement of the tensioning element into an angular movement that is transmitted to the anchoring tube in order to stretch the rubber, and (ii) a tension arm or sole plate which is soldered to the cover of the case at one end and which comprises a perforation through which passes a fork-shaped tensioning element. Said perforation provides a support point for the tensioning element which in turn generates a longitudinal movement that can be used to adjust the tension of the rubber to the desired level.
