Abstract

A motor vehicle with a wheel, a wheel case enveloping the wheel, and an air duct leading to the wheel case, wherein the air duct incorporates an adjustable element, which in a first position steers the air entering into the wheel case through the air duct into a gap between an inner flank of the wheel and an inner wall of the wheel case, and in a second position diverts the air by an outer flank of the wheel.

First claim

1 - 13 . (canceled)

14 . A motor vehicle with a wheel, a wheel case enveloping the wheel, and an air duct leading to the wheel case, wherein the air duct incorporates an adjustable element, which in a first position steers the air entering into the wheel case through the air duct into a gap between an inner flank of the wheel and an inner wall of the wheel case, and in a second position diverts the air by an outer flank of the wheel.

15 . The motor vehicle according to claim 14 , with a brake that is secured in a recess to the inner flank of the wheel.

16 . The motor vehicle according to claim 14 , in which the air duct exhibits a closed cross section.

17 . The motor vehicle according to claim 14 , in which an inlet opening of the air duct lies in the front of the vehicle.

18 . The motor vehicle according to claim 14 , in which the air duct branches into a brake air duct, through which the air flows into the gap, and a side air duct, through which the air flows by the outer flank of the wheel.

19 . The motor vehicle according to claim 18 , in which the air flow exiting the brake air duct is directed against the inner flank of the wheel.

20 . The motor vehicle according to one of claim 18 , in which an outlet opening of the brake air duct in the wheel case for the most part lies on the side of a plane facing the middle of the vehicle, which is perpendicular to the wheel axle and touches the inner flank of the wheel.

21 . The motor vehicle according to one of claim 18 , in which an outlet opening of the side air duct lies in proximity to the outer flank of the wheel.

22 . The motor vehicle according to one of claim 18 , in which the expansion of an outlet opening of the side air duct is greater in the vehicle height than in the transverse direction of the vehicle.

23 . The motor vehicle according to one of claims 18 , in which the adjustable element is positioned between the brake air duct and side air duct.

24 . The motor vehicle according to claim 14 , with an actuator, which brings the adjustable element into the first position given a delay of the vehicle.

25 . The motor vehicle according to claim 24 , with a control circuit for activating the actuator.

26 . The motor vehicle according to claim 25 , in which the control circuit is set up to determine the duration for which the adjustable element remains in the first position after a braking process has concluded as a function of the intensity of the braking process.
