Abstract

Selon l'invention, une liaison de roue avant (24) a une première section de support (24a) qui joue le rôle de point de base de rotation, une section de liaison de câble (24b) et une première section de came (24c), et la rotation de la liaison de roue avant (24) autour de la première section de support (24a) tire un câble d'actionnement de frein de roue avant (40). Une liaison de roue arrière (26) a une seconde section de support (26a) qui joue le rôle de point de base de rotation, une section de liaison de moyen d'actionnement (26b), et une seconde section de came (26c), et la liaison de roue arrière (26) tire des moyens d'actionnement de frein de roue arrière (46). Le mouvement de la seconde section de support (26a) provoque la pression par la seconde section de came (26c) de la première section de came (24c), et, en résultat, la liaison de roue avant (24) est tournée.
