Abstract

L'invention concerne une suspension à bras longitudinaux (10) munie d'un robinet de régulation de hauteur (70) combiné à un dispositif anti-glissement (12) qui possède un mécanisme de réajustement automatique (90) qui met de la pression dans le ressort pneumatique de la suspension à bras longitudinaux jusqu'à ce que le bras rotatif (60) du dispositif anti-glissement puisse pivoter librement depuis une position déployée vers une position escamotée, et ce même si la hauteur de course a été réglée trop bas. Le mécanisme de réajustement automatique (90) ajuste la hauteur de la remorque pour éviter que la suspension à bras longitudinaux ne se lie au dispositif anti-glissement en cas de réglage incorrect du robinet de régulation de hauteur (70).
