CA 2545337

An anti-creep locking mechanism for a trailer suspension system is disclosed. The disclosed locking mechanism includes at least one column that may be swung into a first position in a gap formed between a trailer frame and a suspension component to keep a trailer at a predetermined height. The column is biased into the first position by a spring. An actuator, such as an inflatable air bag or an air cylinder with a linkage assembly, is used to overcome the biasing force of the spring and retract the column into a second position, thereby deactivating the anti-creep locking mechanism. The anti-creep mechanism may further include an angle limiter to insure that column is fully retracted once the system is deactivated.

Le présent brevet divulgue un dispositif de verrouillage anticheminant pour les systèmes de suspension de remorque. Le mécanisme anticheminant qui est divulgué comprend au moins une colonne pouvant être installée à une position initiale dans l'espace compris entre le cadre d'une remorque et une composante de la suspension en vue de maintenir la remorque à une hauteur prédéterminée. La colonne est maintenue dans la position initiale au moyen d'un ressort. Un vérin, tel un sac gonflable ou un cylindre pneumatique doté d'une tringle de commande, sert à compenser l'effet ressort et rétracte la colonne dans une deuxième position, désactivant ainsi le dispositif de verrouillage anticheminant. Ce dispositif peut aussi comporter un limiteur d'angle pour faire en sorte que la colonne soit entièrement rétractée lorsque le système est désactivé.
