An anchor piece (6) articulated on a pivot (7) cooperates with an impulse pin (4) via a fork (8) fitted to the anchor piece. This anchor piece carries second (9) and fourth (13) impulse pallet stones respectively cooperating with the first (1) and second (2) wheel sets. The same anchor piece carries first (10) and second (11) locking pallet stones cooperating with the second wheel set (2).
