Abstract
Abstract A front body module (1) which acts as a chassis for a motor car includes a base member (2), two side panel members (3) with respective hollow domed structures (11) defining lateral box structures (13) with the base member (2), a front cross member (4), and a rear cross member (8). The front body module (1) is arranged for the preassembly of all the drive, suspension and steering members (M, C, S, G, D) for the front wheels, so as to constitute a preassembled front modular sub-assembly (16), and is provided with upper and lower attachment parts (7, 12, 15) for the connection of this sub-assembly (16) to a rear sub-assembly (H) of a motor car provided with corresponding attachments (17, 18).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
Front body module which acts as a chassis for a motor car, characterised in that it comprises: - a substantially bowl-shaped base member (2) having a front box part (9), raised lateral edges (6), and rear lateral attachment appendages (7), - two side panel members (3) each including a front wheel arch structure (10), an intermediate hollow domed structure (11) with its cavity (11b) open outwardly and upwardly, and a rear attachment appendage (12), the front and intermediate structures (10,11) and the rear appendages (12) having lower edges (10a, 11a, 12a) coupled respectively to the raised lateral edges (6) and the rear lateral attachment appendages (7) of the base member (2) to define respective lateral box structures (13) connected to the front box part (9) of the base member (2), - a front cross member (4) which interconnects the front of the wheel arch structures (10) above the front box part (9) of the base member (2), and - a rear cross member (8) which interconnects the rear lateral attachment appendages (7) of the base member (2).
