Title (EN) METHOD FOR DETERMINING AGING OF A VEHICLE SUSPENSION ARRANGEMENT
(FR) PROCÉDÉ DE DÉTERMINATION DU VIEILLISSEMENT D'UN SYSTÈME DE SUSPENSION DE VÉHICULE
Abstract:
(EN) The present invention relates to a method for determining aging of a vehicle suspension arrangement (100) arranged between a frame and a wheel axle of a vehicle, said suspension arrangement (100) comprising a flexible bellows (102) for damping motions from said wheel axle, the method comprising the steps of determining a distance moved by a portion of the flexible bellows (102) when the suspension arrangement is exposed to an external load; determining a gas pressure level within said flexible bellows (102) when the portion of said flexible bellows (102) has moved said distance; determining a relationship between the determined gas pressure level within said flexible bellows and said distance moved by the portion of the flexible bellows; comparing the relationship with a predetermined threshold level; and determining that said flexible bellows is aged if a difference between the relationship and the predetermined threshold level is outside a predetermined threshold range.
(FR) La présente invention concerne un procédé de détermination du vieillissement d'un agencement de suspension de véhicule (100) disposé entre un châssis et un essieu de roue d'un véhicule, ledit agencement de suspension (100) comprenant un soufflet flexible (102) pour amortir des mouvements à partir dudit essieu de roue, le procédé comprenant les étapes consistant à déterminer une distance parcourue par une partie du soufflet flexible (102) lorsque l'agencement de suspension est exposé à une charge externe ; à déterminer un niveau de pression de gaz dans ledit soufflet flexible (102) lorsque la partie dudit soufflet flexible (102) s'est déplacée de ladite distance ; à déterminer une relation entre le niveau de pression de gaz déterminé dans ledit soufflet flexible et ladite distance parcourue par la partie du soufflet flexible ; à comparer la relation à un niveau de seuil prédéfini ; et à déterminer que ledit soufflet flexible est vieilli si une différence entre la relation et le niveau de seuil prédéfini se trouve à l'extérieur d'une plage de seuil prédéfinie.
