Drive wheel (6) is designed to pivot around a first axis (X-X'), which in particular is horizontal, for the purpose of advance of the vehicle, and around a second axis (Y-Y'), which in particular is vertical, for the purpose of steering of the vehicle, while fairing (8) extends laterally to the vicinity of wheel (6) when the vehicle is in operation, so that it at least partly covers an outer side of said wheel. Fairing (8) is not linked in rotation to wheel (6) around the first axis, with the result that it is not constrained to rotate around said axis during the advance of the vehicle, whereas said fairing is linked in rotation to said wheel around the second axis, so that it follows the steering movements of said wheel.
