Abstract

A vehicle substructure includes at least one wing device for producing at least one underflow and at least one overflow from inflowing air to improve a downforce, the at least one wing device having at least one air-guiding apparatus for dividing the inflowing air into at least one wing air flow for the underflow of the wing device and into at least one structure air flow for at least one vehicle component. The air-guiding apparatus includes at least one adaptable air-guiding element. A dividing ratio of the at least one wing air flow and the at least one structure air flow can be flexibly set by at least one adaptation of the air guiding element.

Claims

1. A vehicle substructure, comprising:

at least one wing device for producing at least one underflow and at least one overflow from inflowing air to improve a downforce, the at least one wing device having at least one air-guiding apparatus for dividing the inflowing air into at least one wing air flow for the at least one underflow of the wing device and into at least one structure air flow for at least one vehicle component,

wherein the at least one air-guiding apparatus includes at least one adaptable air-guiding element, and

wherein a dividing ratio of the at least one wing air flow and the at least one structure air flow can be flexibly set by at least one adaptation of the at least one air guiding element.

2. The vehicle substructure as claimed in claim 1, wherein the at least one air-guiding apparatus comprises at least one receiving device for the at least one air-guiding element, and wherein the at least one air-guiding element is arranged interchangeably on the receiving device.

3. The vehicle substructure as claimed in claim 1, wherein the at least one adaptable air-guiding element includes at least two mutually interchangeable air-guiding elements, wherein the at least two mutually interchangeable air-guiding elements differ with respect to the dividing ratio of the wing air flow and the structure air flow.

4. The vehicle substructure as claimed in claim 3, wherein the at least two mutually interchangeable air-guiding elements have different angles of attack.

5. The vehicle substructure as claimed in claim 1, wherein the at least one adaptable air-guiding element is of adjustable design.

6. The vehicle substructure as claimed in claim 1, wherein at least one angle of attack of the at least one adaptable air-guiding element is adjustable.

7. The vehicle substructure as claimed in claim 1, wherein the at least one air-guiding apparatus has at least one receiving device, and wherein the at least one adaptable air-guiding element is connected pivotably to the at least one receiving device.

8. The vehicle substructure as claimed in claim 7, wherein the at least one adaptable air-guiding element and the at least one receiving device are connected to each other via at least one hinge device.

9. The vehicle substructure as claimed in claim 8, wherein the at least one adaptable air-guiding element and/or the at least one receiving device is connected integrally to the hinge device, and wherein the hinge device is provided by at least one flexible hinge portion of the at least one adaptable air-guiding element and/or of the at least one receiving device.

10. The vehicle substructure as claimed in claim 8, wherein the at least one adaptable air-guiding element is designed as a solid component with at least one soft component, and wherein the soft component provides the hinge device.

11. The vehicle substructure as claimed in claim 1, wherein the at least one adaptable air-guiding element is of flexible design and is manufactured from a rubber material and/or an elastomer material.

12. The vehicle substructure as claimed in claim 1, wherein the at least one adaptable air-guiding element is adaptable and pivotable by means of at least one actuator device.

13. The vehicle substructure as claimed in claim 12, wherein the at least one actuator device is operatively connected to at least one control device, and wherein the at least one adaptable air-guiding element can be set using the at least one actuator device depending on at least one operating state of a carrier vehicle and on a driving speed of the carrier vehicle.

14. The vehicle substructure as claimed in claim 1, wherein the vehicle component comprises at least one charge air cooling device, and wherein the at least one structure air flow is supplied as cooling air thereto.

15. The vehicle substructure as claimed in claim 1, wherein the vehicle substructure is designed as a rear wing apparatus.

16. The vehicle substructure as claimed in claim 1, wherein the air-guiding element is arranged in the forward direction of a carrier vehicle beginning in front of the wing device.
