A suspended axle (31) of the articulated-connection type for industrial vehicles comprises a central casing (32) from which two arms (34) extend, each of which carries, at one of its ends, a support (36) for a wheel, the axle (31) being connected to the chassis (52) of the industrial vehicle by means of first bars set transversely and second bars set longitudinally with respect to the vehicle, where the transverse bars comprise a Panhard rod (54). In addition, interposed between the axle (31) and the chassis (52) are hydraulic elements (84). The longitudinal bars each consist of a single strut (64) having one end connected to the central casing (32) and one, opposite, end connected to the chassis (52) with interposition of a ball-and-socket joint (68).

The axle (31) according to claim 1, wherein said strut (64) is integral with said central casing (32). 4. The axle (31) according to claim 1, wherein said Panhard rod (54) is hinged, on one side, at a point corresponding to an axis of symmetry (60) of said axle (31), and on the other side, it is fixed in the proximity of an edge of said chassis (52). 5. The axle (31) according to claim 1, wherein a ball-and-socket joint (68) is fixed to a support (70), wherein said support (70) is fixed underneath a box (72) of a central power divider of said industrial vehicle. 6. The axle (31) according to claim 5, wherein said box (72) is fixed to a plate (76) integral with cross members (78) of said chassis (52). 7. The axle (31) according to claim 1, wherein a second end of said strut (64) is bent (80) and is integral with said central casing (32) of said axle (31). 8. The axle (31) according to claim 1, wherein said ribbings are fixed at the front to said arms (34) of said axle (31), said ribbings (82) performing a stiffening function for the structure of said axle (31). 9. The axle (31) according to claim 1, wherein said hydraulic elements (84) consist of double-acting hydraulic cylinders. 10. The axle (31) according to claim 9, wherein said hydraulic cylinders (84) are supplied by an electronically controlled hydraulic power unit which provides control of the sensitivity of said hydraulic cylinders to loading of a dampened element in such a way as to limit the stroke range of said hydraulic cylinders or to perform a self-leveling function for the industrial vehicle. 11. The axle (31), according to claim 1, wherein said axle is designed for steering. 12. The axle (31) according to claim 1, wherein said axle is designed for traction. 13. The axle (31) according to claim 1, wherein said Panhard rod (54) comprises a hydraulic or pneumatic cylinder having a limited stroke that causes the stem of the piston of said Panhard rod (54) to extend out of one of the cylinders and allow said chassis (52) to be offset with respect to said axle (31).
