Abstract:
1. Aerodynamically constructed covering part for covering an entire underside of a vehicle, comprising at least one central vent hole in the covering part for guiding a partial flow of cold fresh air flowing through between the covering part and a roadway during a driving operation to a space surrounding at least one of an engine compartment and a transmission space for cooling components therein, and aerodynamically optimized and transversely extending suction gills provided on the covering part and defining vacuum zones for carrying away the heated air situated in the space disposed above downwardly toward the roadway, the suction gills being spaced laterally from the vent hole, wherein, as viewed in a longitudinal direction of the vehicle, said suction gills are arranged behind one another with an air passage opening defined between each two adjacent suction gills so as to be set against the flowing cold fresh air.
