An axle/suspension system for the trailer of a tractor-trailer vehicle combination includes a device for leveling the trailer floor. A selected one of a pair of suspension assemblies of the system is pivotally attached to a vehicle frame bracket or hanger having vertically-oriented oval sidewall openings and vertically-spaced horizontally extending eccentric collar guide tabs. The frame hanger, upon a certain manual rotational adjustment of an eccentric alignment collar with a breaker bar, causes a bolt which pivotally attaches the suspension assembly beam to the hanger to be vertically adjusted, which in turn causes vertical adjustment of the beam and the axle attached to the beam, resulting in the raising or lowering of a sidewardly leaning trailer floor to a generally horizontally level position.

La présente invention concerne un système train de roue/suspension pour la remorque d'un semi-remorque, lequel système comprend un dispositif de mise à niveau de plancher de remorque. Deux ensembles de suspension choisis dans le système sont reliés de manière pivotante à la patte de fixation du châssis du véhicule ou crochet présentant des ouvertures de parois latérales ovales verticalement orientées et des onglets à bague excentrique s'étendant de manière horizontale et verticalement espacés. Lors d'un certain réglage manuel par rotation d'une bague d'alignement excentrique avec une barre de rupteur, le crochet de châssis entraîne l'ajustement vertical d'un boulon, lequel relie par pivotement la barre de la suspension au crochet, lequel boulon, à son tour provoque l'ajustement vertical de la barre et la fixation du train de roue à la barre, ce qui permet de relever ou d'abaisser un plancher de remorque inclinable latéralement dans une position généralement horizontale.
