Abstract

A motor vehicle ( 1 ) has a wheel arch ( 3 ), in which a wheel ( 4 ) is arranged, and has an air guiding apparatus ( 20 ) for guiding an air flow ( 8 ) that flows onto the wheel arch ( 3 ) during operation of the motor vehicle. The air guiding apparatus ( 20 ) is configured and arranged in such a way that a first part air flow ( 11 ) is guided past an inner side of the wheel ( 4 ) and a second part air flow ( 12 ) is guided past an outer side of the wheel ( 4 ). The two part air flows ( 11, 12 ) then are combined again behind the wheel arch ( 3 ) in a vehicle longitudinal direction.

First claim

What is claimed is:

1. A motor vehicle comprising at least one wheel arch in which a wheel is arranged, and at least one air guiding apparatus for an air flow that flows onto the wheel arch during operation of the motor vehicle, the air guiding apparatus being configured and disposed to guide a first part air flow past an inner side of the wheel, to guide a second part air flow past an outer side of the wheel, and to combine the first and second part air flows behind the wheel arch in a vehicle longitudinal direction.

2. The motor vehicle of claim 1 , wherein the air guiding apparatus comprises at least one front air guiding device that is configured to guide the air flow that flows onto the wheel arch during operation of the motor vehicle into the first and second part air flows.

3. The motor vehicle of claim 2 , wherein the at least one front air guiding device comprises a first front air guiding device that guides the first part air flow past the inner side of the wheel.

4. The motor vehicle of claim 3 , wherein the at least one front air guiding device comprises a second front air guiding device that guides the second part air flow past the outer side of the wheel.

5. The motor vehicle of claim 2 , wherein the air guiding apparatus further comprises at least one rear air guiding device configured to combine the first and second part air flows behind the wheel arch in the vehicle longitudinal direction.

6. The motor vehicle of claim 5 , wherein the at least one rear air guiding device comprises a first rear air device configured to guide the first part air flow behind the wheel arch toward the second part air flow.

7. The motor vehicle of claim 6 , wherein the at least one rear air guiding device further comprises at least one second rear air guiding device configured to guide the second part air flow behind the wheel arch toward the first part air flow.

8. The motor vehicle of claim 1 , wherein the at least one front wheel arch comprises two front wheel arches and the at least one air guiding apparatus comprises two air guiding apparatuses assigned respectively to the two front wheel arches.

9. A method for operating a motor vehicle, comprising: guiding a first part air flow past an inner side of a wheel; guiding a second part air flow past an outer side of the wheel; and combining the first and second part air flows behind the respective wheel in a vehicle longitudinal direction.
