<p>The axle has wheel supports pivoting around a vertical axis, where each wheel support is connected to one end of each of driving rods (32). Another end (34) of each driving rod is connected to one end (36) of a swing bar (38). Another end (40) of the swing bar is driven by an actuator (42). The actuator is fixed on a support element formed by a crosspiece or a cradle. An intermediate part (46) of the swing bar is pivotably mounted on a cylindrical body (48) of the actuator. The body of the actuator comprises a cylinder (50) that moves along a transverse axis (B).</p> |
