A vehicle that is constructed to haul heavy loads and has a leaf spring suspension is provided with an auxiliary air spring suspension, in parallel with the leaf spring suspension, on at least one of the axles of the vehicle. The air spring is an airbag located at a position midway between the pair of leaf springs for such axle. The airbag via a valved air line can be inflated, deflated and sealingly closed. In the latter state it is used to indicate the weight of a load as the load is being added to the vehicle. The airbag is inflated to a higher pressure to provide a partial air ride for the vehicle when travelling in a no load condition.
Cette invention concerne un poids lourd à suspension à ressorts à lames équipé d'une suspension auxiliaire à ressorts pneumatiques parallèlement à la suspension à ressorts à lames sur au moins un des essieux. Le ressort pneumatique est un coussin à air situé à mi-chemin entre les deux ressorts à lames de l'essieu. Le coussin à air se gonfle et se dégonfle au moyen d'une conduite d'air équipée d'un robinet, celui-ci servant aussi à le maintenir sous pression constante. Robinet fermé, le coussin sert d'indicateur de charge du véhicule. Il se gonfle à une pression plus élevée pour doter le véhicule d'une suspension partiellement pneumatique lorsqu'il circule à vide.
