Title
(EN) VEHICLE SUSPENSION ARRANGEMENT
(FR) DISPOSITION DE SUSPENSION DE VEHICULE
Abstract
(EN)
The invention relates to an arrangement for a suspension for a load carrying vehicle, which suspension is provided with air springs and comprises at least one front axle and at least two rear axles, and where each rear axle is provided with at least one pair of corresponding suspension air springs and at least one air spring is provided for lifting one of said rear axles. The suspension air springs for at least the rearmost axle is connected to the air spring for lifting one of said rear axles by a conduit for compressed air, which conduit is provided with a controllable valve, whereby the controllable valve is arranged to open during a vehicle loading process. The invention further relates to a vehicle provided with the arrangement, and a method for carrying out a loading operation using the arrangement.
(FR)
La présente invention concerne une disposition pour une suspension de véhicule de chargement, laquelle suspension est munie de ressorts pneumatiques et comprend au moins un essieu avant et au moins deux essieux arrière, chaque essieu étant muni en outre d’au moins une paire de ressorts pneumatiques de suspension correspondants et au moins un ressort pneumatique est prévu pour soulever un desdits essieux arrière. Le ressort pneumatique de suspension pour au moins l’essieu le plus à l’arrière est relié au ressort pneumatique pour soulever un desdits essieux arrière par une conduite d’air comprimé, ladite conduite est pourvue d’une soupape régulable. Selon le procédé d’invention, la soupape régulable est disposéede manière à s’ouvrir pendant un processus de chargement du véhicule. L’invention concerne en outre un véhicule pourvu de la disposition et un procédé d’exécution d’une opération de chargement utilisant la disposition.
