An axle assembly for a vehicle includes a chassis (1) and at least two wheels (2, 3) suitable for coming into contact with ground (4). A unit beam (5) associates the two wheels with the chassis and holds them in two substantially parallel planes (6, 7). A point (10) situated substantially between the two ends (11, 12) of the beam is prevented from rotating relative to the chassis. Two arms (13, 14) are fixed substantially at one of their ends to the end of respective beams. The two wheels are rotatably mounted to the opposite ends of the arms. The two portions (36, 37) of the beam (8) situated on opposite sides of the point situated between the two ends of the beam are made of a material such that each of them has anisotropic torsion elasticity (42, 43) in the opposite direction to the other. |
