Abstract

L'invention porte sur un procédé de fabrication qui crée une séparation entre plancher élevé/plancher bas dans un véhicule à cabine avancée ou analogue, tel qu'un fourgon, principalement dans un compartiment à marchandises arrière. Le procédé supprime les éléments élévateurs utilisés dans la technique classique pour surélever un plancher, en réduisant ainsi le coût et le poids. Derrière le siège de conducteur (S), un châssis à plancher surélevé (UBH) est divisé en un châssis côté cabine (UBC) et en un châssis arrière (UBR), et le châssis arrière séparé (UBR) est relié au châssis côté cabine (UBC) par un élément d'abaissement de plancher (5), en créant ainsi un châssis à plancher bas (UBL).
