Abstract

A vehicle has an air-guiding device arranged on a lower side of the vehicle in front of a vehicle wheel. The air-guiding device includes an air-guiding body which has a side region running substantially in the vertical direction of the vehicle and facing a vehicle center, and a bottom region which faces an underlying surface and is connected to the side region and is spaced apart from the lower side. In an outer region of the air-guiding body, which faces away from the vehicle center and is connected to the bottom region and is formed with a convex curvature with respect to the outer side of the vehicle, an air flow can be directed in the direction of an outer flank of the vehicle wheel, while an air flow can be oriented in the longitudinal direction of the vehicle via the side region guiding surface.

First claim

What is claimed is:

1. A vehicle, comprising:
an air-guiding device arranged on a lower side of the vehicle in front of a vehicle wheel, which air-guiding device comprises an air-guiding body having a guiding surface essentially extending in a vertical direction of the vehicle and facing a vehicle center, and a bottom region which faces an underlying surface, is connected with the guiding surface and is spaced away from the lower side of the vehicle, wherein
the air-guiding body has an outer region which faces away from the vehicle center, is connected with the bottom region and is constructed with a convex curvature with respect to an outer side of the vehicle such that an air stream in the outer region of the air-guiding body is guidable in the direction of an outer flank of the vehicle wheel, while another air stream is oriented by way of the guiding surface in the longitudinal direction of the vehicle, and
the air-guiding device has an additional air-guiding body, which is arranged in the transverse direction of the vehicle between the air-guiding body and the vehicle center in the longitudinal direction of the vehicle, is constructed with a lower depth than the air-guiding body and extends directly from the guiding surface or at a distance from the guiding surface essentially in the direction of the vehicle center.

2. The vehicle according to claim 1 , wherein
the other air stream is oriented by way of the guiding surface additionally in the direction of the vehicle center.

3. The vehicle according to claim 1 , wherein
an edge extending essentially in the longitudinal direction of the vehicle is provided in a joint region between the guiding surface and the bottom region.

4. The vehicle according to claim 2 , wherein
an edge extending essentially in the longitudinal direction of the vehicle is provided in a joint region between the guiding surface and the bottom region.

5. The vehicle according to claim 1 , wherein
the guiding surface is arranged to be extending at least approximately at a right angle with respect to the lower side of the vehicle.

6. The vehicle according to claim 4 , wherein
the guiding surface is arranged to be extending at least approximately at a right angle with respect to the lower side of the vehicle.

7. The vehicle according to claim 1 , wherein
the bottom region and the guiding surface of the air-guiding body increasingly project beyond the lower side of the vehicle, starting from a region of the air-guiding body facing a forward side of the vehicle, in the direction of a region facing away from the forward side of the vehicle.

8. The vehicle according to claim 6 , wherein
the bottom region and the guiding surface of the air-guiding body increasingly project beyond the lower side of the vehicle, starting from a region of the air-guiding body facing a forward side of the vehicle, in the direction of a region facing away from the forward side of the vehicle.

9. The vehicle according to claim 3 , wherein
the guiding surface and the edge of the joint region are constructed with a concave curvature with respect to the vehicle center.

10. The vehicle according to claim 8 , wherein
the guiding surface and the edge of the joint region are constructed with a concave curvature with respect to the vehicle center.

11. The vehicle according to claim 7 , wherein
a distance between a region of the guiding surface facing the forward side of the vehicle and the vehicle center in the transverse direction of the vehicle is smaller than a distance between the region of the guiding surface facing away from the forward side of the vehicle and the vehicle center in the transverse direction of the vehicle.

12. The vehicle according to claim 10 , wherein
a distance between a region of the guiding surface facing the forward side of the vehicle and the vehicle center in the transverse direction of the vehicle is smaller than a distance between the region of the guiding surface facing away from the forward side of the vehicle and the vehicle center in the transverse direction of the vehicle.

13. The vehicle according to claim 1 , wherein
the additional air-guiding body increasingly projects beyond the lower side of the vehicle starting from a region of the additional air-guiding body facing the forward side of the vehicle in the direction of the region facing away from the forward side of the vehicle.

14. The vehicle according to claim 13 , wherein
at least in the region of the additional air-guiding body, at least one air-guiding web is provided, which is arranged between the guiding surface of the air-guiding body and the vehicle center and extends essentially in the longitudinal direction of the vehicle.

15. The vehicle according to claim 1 , wherein
at least in the region of the additional air-guiding body, at least one air-guiding web is provided, which is arranged between the guiding surface of the air-guiding body and the vehicle center and extends essentially in the longitudinal direction of the vehicle.

16. The vehicle according to claim 14 , wherein
the air-guiding web has a concave curvature corresponding at least approximately to the guiding surface.

17. The vehicle according to claim 14 , wherein
a height of the air-guiding web increases at least in sections starting from a region facing the forward side of the vehicle in the longitudinal direction of the vehicle.

18. The vehicle according to claim 16 , wherein
a height of the air-guiding web increases at least in sections starting from a region facing the forward side of the vehicle in the longitudinal direction of the vehicle.

19. A vehicle, comprising:
an air-guiding device arranged on a lower side of the vehicle in front of a vehicle wheel, which air-guiding device comprises an air-guiding body having a guiding surface essentially extending in a vertical direction of the vehicle and facing a vehicle center, and a bottom region which faces an underlying surface, is connected with the guiding surface and is spaced away from the lower side of the vehicle, wherein
the air-guiding body has an outer region which faces away from the vehicle center, is connected with the bottom region and is constructed with a convex curvature with respect to an outer side of the vehicle such that an air stream in the outer region of the air-guiding body is guidable in the direction of an outer flank of the vehicle wheel, while another air stream is oriented by way of the guiding surface in the longitudinal direction of the vehicle,
the other air stream is oriented by way of the guiding surface additionally in the direction of the vehicle center, and
an edge extending essentially in the longitudinal direction of the vehicle is provided in a joint region between the guiding surface and the bottom region.

20. A vehicle, comprising:
an air-guiding device arranged on a lower side of the vehicle in front of a vehicle wheel, which air-guiding device comprises an air-guiding body having a guiding surface essentially extending in a vertical direction of the vehicle and facing a vehicle center, and a bottom region which faces an underlying surface, is connected with the guiding surface and is spaced away from the lower side of the vehicle, wherein
the air-guiding body has an outer region which faces away from the vehicle center, is connected with the bottom region and is constructed with a convex curvature with respect to an outer side of the vehicle such that an air stream in the outer region of the air-guiding body is guidable in the dire
