Commercial vehicle design capable of many variants, includes self-supporting cab frame, carrier frame and base module

摘要

The cab (3) has a self-supporting frame (4) with a carrier frame (5) built onto its rear. The base module can be connected either with a first- or a second built on module. The first has a two-dimensional main frame (11) fastened to it, forming a self-supporting unit. The second has a three-dimensional frame, which is fastened on the built-on carrier frame and on the cab frame. The built-on carrier frame and the built on module frame form a self-supporting unit, with rigid fastenings to the cab. An Independent claim is included for the corresponding system (method) of constructing vehicle variants.
