1. An axle mounted on a chassis of a vehicle, the axle comprising a central box, a first support arm connected to a first wheel of the vehicle and slidingly mounted inside the central box, and a second support arm connected to a second wheel of the vehicle, the second support arm being longitudinally translatable inside the first support arm, wherein the axle also includes a guide box fastened to the central box, the guide box comprising a rectangular tube and defining an outer annular volume between the central box and the tube, and an inner volume inside the tube, the first support arm being received inside the outer annular volume and being able to be guided by the guide box along a first longitudinal translation path, the second support arm being received inside the inner volume and being able to be guided by the guide box along a second longitudinal translation path. 2. The axle according to claim 1, comprising at least one actuator, forming a means for translating at least one of the first and second support arms, and said at least one actuator extends along the longitudinal translation axis. 3. The axle according to claim 2, comprising a first cylinder and a second cylinder, respectively forming means for translating the first support arm and means for translating the second support arm, the first and second cylinders respectively being fastened to the first and second support arms each at least at a first respective fastening point. 4. The axle according to claim 3, wherein the first and second cylinders extend inside the inner volume of the guide box and in that at least one cylinder is fastened to the rectangular tube at least at one second fastening point. 5. The axle according to claim 3, wherein the first and second cylinders extend outside the central box and in that at least one cylinder is fastened to the central box at least at one second fastening point. 6. The axle according to claim 1, wherein the guide box has a length strictly smaller than the length of the central box. 7. The axle according to claim 1, wherein the second support arm comprises, on one of its outer walls, at least one support element withstanding pressure or forces exerted on the axle, said at least one support element being able to be in contact with an inner wall of the guide box. 8. The axle according to claim 1, wherein the rectangular tube or the first support arm comprises, on one of the outer walls, at least one support element withstanding pressure or forces exerted on the axle, said at least one support element being able to be in contact with an inner wall of the first support arm, or an inner wall of the central box. 9. The axle according to claim 1, wherein the central box, the guide box, the first support arm and the second support arm each have a substantially rectangular cross-section. 10. A vehicle, equipped with a chassis, wherein the vehicle is also equipped with at least one axle according to claim 1, said at least one axle being mounted on the chassis of the vehicle.
