Abstract

Claims (12)

1. An undercarriage panelling element ( 24 ) of a vehicle ( 10 ), comprising:

a first air guidance region ( 28 );

a second air guidance region ( 30 , 30 ′, 30 ″) that is attached to the first air guidance region ( 28 ) rearwards in a longitudinal direction of the vehicle ( 20 ) and angled away from the first air guidance region ( 28 ) such that the second air guidance region ( 30 , 30 ′, 30 ″) rises relative to the first air guidance region ( 28 ) in a vertical direction of the vehicle; and

a flow separation edge ( 36 ) that is attached to the second air guidance region ( 30 , 30 ′, 30 ″), wherein on the flow separation edge ( 36 ) an air flow guided along the second air guidance region ( 30 , 30 ′, 30 ″) comes off in a defined manner when the vehicle ( 10 ) is travelling forwards and wherein the flow separation edge ( 36 ) is disposed behind the second air guidance region ( 30 , 30 ′, 30 ″) in the longitudinal direction of the vehicle ( 20 ) and extends downwards away from the second air guidance region ( 30 , 30 ′, 30 ″) over its entire extension running in the vertical direction of the vehicle in parallel or obliquely to the vertical direction of the vehicle ( 32 ) such that the flow separation edge ( 36 ) extends downwards away from the second air guidance region ( 30 , 30 ′, 30 ″) in the vertical direction of the vehicle and such that the flow separation edge ( 36 ) is a jut of the undercarriage panelling element ( 24 ) pointing downwards in the vertical direction of the vehicle starting from a rear end of the second air guidance region ( 30 , 30 ′, 30 ″);

wherein a rear axle ( 12 ) of the vehicle on which wheels ( 14 ) are mounted is disposed behind the undercarriage panelling element ( 24 ) in the longitudinal direction of the vehicle ( 20 ) and wherein the rear axle ( 12 ) is at least partially covered downwards in the vertical direction of the vehicle ( 32 ) by a further panelling element ( 38 a , 38 b , 38 c ) disposed behind the undercarriage panelling element ( 24 ) in the longitudinal direction of the vehicle ( 20 ).

2. The undercarriage panelling element ( 24 ) according to claim 1 , wherein the second air guidance region ( 30 , 30 ′, 30 ″) is directly attached to the first air guidance region ( 28 ).

3. The undercarriage panelling element ( 24 ) according to claim 1 , wherein the second air guidance region ( 30 , 30 ′, 30 ″) is formed in one piece with the first air guidance region ( 28 ) and/or with the flow separation edge ( 36 ).

4. The undercarriage panelling element ( 24 ) according to claim 1 , wherein the first air guidance region ( 28 ) runs in parallel to a roadway ( 9 ).

5. An arrangement, comprising:

an undercarriage panelling ( 22 ) on a structure ( 13 ) of a vehicle ( 10 ), wherein a base of the structure ( 13 ) is at least partially covered downwards in a vertical direction of the vehicle ( 10 ) by the undercarriage panelling ( 22 );

wherein the undercarriage panelling ( 22 ) has the undercarriage panelling element ( 24 ) according to claim 1 .

6. The arrangement according to claim 5 , wherein a diffuser ( 40 ) of the vehicle ( 10 ) is disposed behind the rear axle ( 12 ) in the longitudinal direction of the vehicle ( 20 ).
