Abstract

A motor vehicle structure includes two left and right bell-shaped suspension element supports arranged inside a front compartment close to a bulkhead of the vehicle. The suspension element supports are respectively adjacent to side walls of the front compartment. Each of the suspension element supports includes an internal face opposite the side wall. The structure also includes left and right spacers that extend respectively between the left and right suspension element supports and the rigid cross member, in a substantially longitudinal direction. The spacers are respectively anchored to the internal faces of the two suspension element supports. The spacers each have a skirt-shaped edge that can be applied to the suspension element supports, and a folded edge extending between a free end and an opposing attachment end to be joined to the cross member. The spacers include a central portion joining the folded edge and the skirt-shaped edge together.

First claim

The invention claimed is:

1. A motor vehicle structure for a motor vehicle including a front compartment having side walls and a passenger compartment that is separated from said front compartment by a bulkhead, said bulkhead having a rigid cross member, said structure comprising:
left and right bell-shaped suspension element supports arranged inside said front compartment close to said bulkhead, and that are respectively adjacent to said side walls, each of the bell-shaped suspension element supports including an internal face opposite the side wall; and
left and right spacers that extend respectively between said left and right bell-shaped suspension element supports and said rigid cross member, in a substantially longitudinal direction,
wherein said spacers are respectively anchored to the internal faces of said left and right bell-shaped suspension element supports,
wherein said spacers each have a skirt-shaped edge that can be applied to said bell-shaped suspension element supports, and a folded edge extending between a free end and an opposing attachment end that is configured to be joined to said cross member, said spacers including a central portion joining said folded edge and said skirt-shaped edge together, and
wherein an overall shape of the central portion of said spacers is substantially triangular.

2. The motor vehicle structure as claimed in claim 1 , wherein said bell-shaped suspension element supports include respectively an upper portion forming a cover, and said spacers are anchored near to said upper portions forming a cover.

3. The motor vehicle structure as claimed in claim 1 , wherein said bell-shaped suspension element supports are rigidly connected to said side walls respectively.

4. The motor vehicle structure as claimed in claim 1 , wherein said folded edge of said spacer includes a curved portion that is located towards said free end and that extends substantially perpendicular to said skirt-shaped edge.

5. The motor vehicle structure as claimed in claim 4 , wherein said attachment end includes a perforated tab extending substantially perpendicular to said curved portion.

6. The motor vehicle structure as claimed in claim 1 , wherein said spacers are formed from a single piece of pressed metal.

7. The motor vehicle structure as claimed in claim 1 , wherein said spacers extending respectively between said left and right bell-shaped suspension element supports and said cross member are mirror images of one another.

8. The motor vehicle structure as claimed in claim 1 , wherein said attachment end includes a perforated tab extending substantially perpendicular to a curved portion of said folded edge of said spacer.

9. The motor vehicle structure as claimed in claim 8 , wherein said perforated tab is oriented substantially vertically and transversely.

10. The motor vehicle structure as claimed in claim 1 , wherein said attachment end is welded to said cross member.

11. The motor vehicle structure as claimed in claim 1 , wherein said skirt-shaped edge of each of said spacers is rigidly attached to said bell-shaped suspension element supports.

12. The motor vehicle structure as claimed in claim 6 , wherein said metal that forms said spacers is steel.
