Abstract

An air guiding device for improving the road grip of a vehicle has a wing against which the air stream flows. The wing extends approximately in the transverse direction, generating a negative lift and being supported on the vehicle. The wing comprises an upper and a lower wing element which extend transversely to the vehicle, are arranged at a distance from one another and are connected with one another by end cheeks which are arranged on the end side and have an approximately U-shaped cross-section. The two wing elements and the end cheeks form a bounded gap through which air flows.
