Abstract

A floor structure of a motor vehicle is provided that includes, but is not limited to a mounting for a starter battery in a cross member adjoining wheel arches for rear wheels. The cross member comprises two stiffening webs and is designed tub-shaped between the stiffening webs. Because of this, the starter battery is reliably protected against a crash.

Claims

1. A floor structure for a motor vehicle, comprising:

side members arranged in a driving direction and laterally delimiting the floor structure with a floor panel;

stiffening webs arranged transversely to the driving direction and interconnecting the side members mounted on the floor panel; and

wheel arches for front and for rear wheels with at least two stiffening webs adjoining the wheel arches of the rear wheels are adapted to delimit a mounting for additional components.

2. The floor structure according to claim 1, wherein the mounting is arranged above a torsion tube of a rear axle.

3. The floor structure according to claim 1, wherein the mounting is arranged behind a rear seat of the motor vehicle.

4. The floor structure according to claim 1, wherein the mounting is tub-shaped and open in a side facing away from the floor panel.

5. The floor structure according to claim 1, wherein a cross member interconnecting the side members and welded to the floor panel comprises the at least two stiffening webs.

6. The floor structure according to claim 1, wherein the stiffening webs are arranged on two cross members interconnecting the side members and welded to the floor panel.

7. The floor structure according to claim 1, wherein the floor panel has a clearance for the mounting.

8. The floor structure according to claim 5, wherein the cross member comprising the stiffening webs and the mounting comprises an opening between the stiffening webs adapted to provide a routing through electrical lines.

9. The floor structure according to claim 1, wherein a cross member is adapted to form a pre-assembled constructional unit with a starter battery and is glued into the mounting.

10. The floor structure according to claim 9, wherein the cross member is manufactured of a plastic.

11. The floor structure according to claim 9, wherein the cross member is manufactured of a light-metal material.

12. The floor structure according to claim 9, wherein the cross member is manufactured of a composite material.

13. The floor structure according to claim 8, wherein a starter battery of a combustion engine of the motor vehicle is arranged in the mounting.

14. The floor structure according to claim 8, wherein the cross member is adapted to close the opening for the routing through electrical lines.

15. The floor structure according to claim 1, wherein the mounting is arranged below a rear seat of the motor vehicle.

16. The floor structure according to claim 5, wherein the cross member is a single cross member.
