Abstract

L'invention concerne un système de commande de traction perfectionné pour véhicule 6x2 modifié. Un ensemble à suspension pneumatique est lié à l'unité de commande antiblocage/traction. De cette façon, en réponse à une situation de commande de traction différentielle, l'air comprimé dans des airbags associés à l'ensemble de la suspension est régulé en vue de transférer une plus grande charge du véhicule sur l'arbre moteur (10). Ceci améliore la capacité de traction. Si l'arbre moteur est déjà à sa charge maximale de régime du véhicule, aucune masse supplémentaire n'est transférée. En outre, des vannes d'isolement (72) sont ajoutées aux lignes de freinage associées à l'arbre traîné (12). Les vannes d'isolement communiquent également directement avec l'unité de commande antiblocage/traction, de sorte que le freinage sur l'arbre traîné est isolé de l'arbre moteur. Ceci élimine la résistance au freinage sur l'arbre traîné, lors d'une situation de commande de traction différentielle.
