Abstract

L'invention concerne une suspension de véhicule à réglage automatique de hauteur. La suspension comprend des jambes à amortisseur oléopneumatique, 16, 18, 21 et 22, dont la longueur moyenne est commandée par des distributeurs sensibles à la hauteur 25, 28 et 34. Les distributeurs commandent la pression fournie par une pompe 45 qui est entraînée par le moteur du véhicule. La pression de la pompe est également appliquée directement à chaque jambe pour maintenir un piston d'un ressort pneumatique, formé dans chaque jambe, en appui contre une butée. Lorsque la pression de la pompe cesse d'être appliquée, les ressorts pneumatiques se détendent pour supporter le véhicule à la hauteur normale. L'invention est applicable à tous les véhicules à suspension fluide à réglage automatique de hauteur, y compris les avions et les véhicules à chenilles.The invention relates to a vehicle suspension with automatic height adjustment. The suspension comprises oleopneumatically damped struts, 16, 18, 21 and 22, the average length of which is controlled by height sensitive valves 25, 28 and 34. The distributors control the pressure supplied by a pump 45 which is driven by the vehicle engine. Pressure from the pump is also applied directly to each leg to keep a piston of an air spring, formed in each leg, resting against a stopper. When pump pressure stops being applied, the air springs relax to support the vehicle at normal height. The invention is applicable to all vehicles with fluid suspension with automatic height adjustment, including airplanes and tracked vehicles.
