<p>The modular frame for transportation vehicles with depressed flatbed (1) comprises a front wheel assembly (5) with a steering wheel assembly, a rear wheel assembly (6) with a fixed wheel assembly, a protruding front structure (2), a protruding rear structure (4) and a central structure (3) between the wheel assemblies. The aforesaid structures (2, 3, 4) can be connected in a removable and non-removable way to said wheel assemblies (5, 6) upon assembly with the same type of attachment (9), eventually also using a disconnectable connection on the protruding rear structure (4) of the bus frame and non-removable permanent connections on the other attachments between the wheel assemblies (5, 6) and the respective frame structure (2, 3). In addition, the frame structure consists of central beams (7), lateral box-type beams (14) and intermediate (16) and end (13) ribs. In the wheel assembly (5, 6) attachment area, the frame structure is equipped with flanges (12) that can be coupled with similar flanges (12) on the wheel assembly to which it must be permanently connected in a non-removable way.</p> |
