Abstract

An air-guiding arrangement is provided for a vehicle. The air-guiding arrangement is arranged in the region in front of a vehicle wheel which is functionally connected to a braking system. At least one air-guiding body is positioned in front of the vehicle wheel and protrudes downwards from an underbody covering part in the direction of the roadway, and at least one duct is positioned in the air-guiding body or on that side of the air-guiding body which faces away from the outside of the vehicle, and is designed to guide incoming travel air in the direction of the braking system. The air-guiding body has a first retaining lip which is arranged between the air-guiding body and the vehicle wheel and which protrudes downward over the air-guiding body in the direction of the roadway. A second retaining lip is provided on that side of the at least one duct which faces away from the outside of the vehicle such that the at least one duct has a gap between the first retaining lip and the second retaining lip.

Claims

1. An air-guiding arrangement for a vehicle, which air-guiding arrangement is arranged in a region in front of a vehicle wheel functionally connected to a braking system, comprising:

at least one air-guiding body, which is positioned in front of the vehicle wheel and protrudes downwards from an underbody covering part in the direction of a road; and

at least one duct, which is positioned in the air-guiding body or on a side of the air-guiding body facing away from an exterior side of vehicle, which duct is configured to guide an inflowing air stream in a direction of the braking system,

wherein

the air-guiding body has a first retaining lip, which is arranged between the air-guiding body and the vehicle wheel and which protrudes downwards in the direction of the road beyond the air-guiding body, and

on a side of the at least one duct facing away from the exterior side of the vehicle, a second retaining lip is provided, so that the at least one duct comprises a gap between the first retaining lip and the second retaining lip.

2. The air-guiding arrangement according to claim 1, wherein

the at least one air-guiding body, the at least one retaining lip and the at least one duct are constructed as an integral component.

3. The air-guiding arrangement according to claim 1, wherein

the at least one air-guiding body and the first retaining lip are constructed as an integral component, the second retaining lip being a component that is spatially separated therefrom.

4. The air-guiding arrangement according to claim 1, wherein

the at least one air-guiding body, the first retaining lip and the second retaining lip are constructed as an integral component.

5. The air-guiding arrangement according to claim 1, wherein

a second air-guiding body is provided on the side of the at least one duct that faces away from the exterior side of the vehicle, which second air-guiding body protrudes downwards from the underbody covering part in the direction of the road, and

the second retaining lip is arranged in the travel direction behind the second air-guiding body or on its rearward end and protrudes downwards in the direction of the road beyond the second air-guiding body.

6. The air-guiding arrangement according to claim 5, wherein

the first air-guiding body and the first retaining lip are constructed as a first integral component, and the second air-guiding body and the second retaining lip are constructed as a second integral component.

7. The air-guiding arrangement according to claim 6, wherein

the first integral component is arranged in a spatially separated fashion from the second integral component, the at least one duct being constructed between the first integral component and the second integral component.

8. The air-guiding arrangement according to claim 6, wherein

the first integral component, the second integral component and the at least one duct are constructed as a single component, the at least one duct being constructed between the first integral component and the second integral component.

9. The air-guiding arrangement according to claim 1, wherein

the at least one duct further has a ramp, which extends from a front side of the vehicle to the gap.

10. The air-guiding arrangement according to claim 9, wherein

the ramp is constructed on an underbody part of the vehicle.

11. The air-guiding arrangement according to claim 9, wherein

the ramp is integrally constructed in the air-guiding device.

12. The air-guiding arrangement according to claim 1, wherein

a height and/or a width of the duct increases in the direction toward the vehicle wheel.

13. The air-guiding arrangement according to claim 1, wherein

the at least one duct has a NACA profile.

14. The air-guiding arrangement according to claim 1, wherein

the air-guiding arrangement is constructed as a one-piece component.

15. A vehicle, comprising at least one air-guiding arrangement according to claim 1.

16. The vehicle according to claim 15, wherein

the at least one air-guiding arrangement is constructed in one piece with a wheel housing cover of the vehicle.
