An elastic suspension for axles of industrial vehicles, particularly axles of earth-movers, which is constituted by two substantially identical and superimposed metal plates; the upper plate is rigidly anchored to the chassis of the vehicle and the lower plate is connected to the conventional oscillating supports of the axle; the plates are mutually hinged along one side which is orientated longitudinally with respect to the vehicle so that they can move mutually apart and mutually closer by virtue of elastic elements which are capable of absorbing the maximum load that bears on the axle; the elastic elements are preferably constituted by a torsion bar which is keyed, with one of its ends, to the axis of the hinge and is rigidly coupled, with its opposite end, to the chassis of the vehicle by a transverse crank-shaped arm which is in turn connected to the stem of a cylinder that is capable of supplying the torque shaft with the necessary preloading for correct operation and of allowing the axle to be suspended or fixed with respect to the chassis by adjusting the stroke of the cylinder.
