Abstract
The air guiding device has one or more air guiding bodies. Each air guiding body has an elongate attachment that extends in the longitudinal direction of the vehicle that bulges in a convex manner, is composed of a flexible or soft-elastic material and is embodied in the form of a half shell having a lateral elongate opening and can be adjusted automatically in the driving condition from a rest position into an operative position, in which it can be lowered in the direction of the roadway. In the rest position, the air guiding body is arranged close to the undersurface and, in the operative position, the air guiding body is held in a lowered position relative to the undersurface.
Claims8
An air guiding device for a vehicle arranged in an area ahead of wheels of the vehicle and projecting down toward the roadway from an undersurface of a wheel arch shell or a front end part, the air guiding device comprising air guiding bodies, each of the air guiding bodies of the air guiding device comprising an elongate attachment that extends in a longitudinal direction of the vehicle, the elongated attachment being made of a flexible material and having a cross section in the form of a half shell having a lateral elongate opening between an undersurface and a lateral edge of the air guiding body, the air guiding bodies being oriented so that the lateral openings face toward one another and toward a center of the vehicle, the air guiding bodies being adjusted automatically in accordance with a driving condition from a rest position at the undersurface into an operative position, in which the air guiding body is lowered toward the roadway.
An air guiding device for a vehicle arranged in an area ahead of at least one wheel of the vehicle and projecting down toward the roadway from an undersurface of a wheel arch shell or a front end part, the air guiding device comprising at least one elongated air guiding body that extends substantially in a longitudinal direction of the vehicle, the air guiding body being made of a flexible material, and being held flexibly on the undersurface at an outer lateral edge and a front end edge by one or more offset tabs in slots in the undersurface, and an inner lateral edge situated opposite the outer lateral edge being free of the undersurface to form an opening so that the air guiding body defines a half shell with the inner lateral edge defining an air separation edge, the air guiding body having a continuous bulging shape that arches down when the vehicle is at rest and bulging down farther at increasing speeds of the vehicle due to an increasing vacuum in proximity to the undersurface and the forces resulting therefrom so that the shape of the air guiding body is adjusted automatically in accordance with vehicle speed.
An air guiding device for a vehicle arranged in an area ahead of a vehicle wheel and projecting down toward the roadway from an undersurface of a wheel arch shell or a front end part, the air guiding device having two identical air guiding bodies arranged ahead of each vehicle wheel, each of the air guiding bodies of the air guiding device comprising an elongate attachment that extends in a longitudinal direction of the vehicle, the elongated attachment being made of a flexible material and having a cross section in the form of a half shell having a lateral elongate opening between an undersurface and a lateral edge of the air guiding body, the lateral openings of the air guiding bodies in the form of half shells lying opposite one another and the air guiding bodies being arranged parallel to one another and being separated by an interspace, the air guiding bodies being adjusted automatically in accordance with a driving condition from a rest position at the undersurface into an operative position, in which the air guiding body is lowered toward the roadway.
