Land vehicle and road vehicle with improved aerodynamics and body for a land vehicle and road vehicle with improved aerodynamics

摘要

At least one body arrangement (K) for a road vehicle (SF), this one with a surface (O), which delimits the body arrangement (K) towards the fluid air, the body arrangement (K) when driving with relative movement to the fluid air on it exerts a displacement effect and thus imposes a directional streamline field with locally different directions on the air mass flow in its surroundings, the local directions of the streamline field in turn being based on the course of the contour of the surface (O) of the body arrangement (K), whereby: in the streamline field , which is induced by the body arrangement (K) on the fluid air in its environment, in an excellent area in which at least the local flow (A), also due to the course of the contour of the surface (O) of the body arrangement (K) , in sections in different directions to the direction of travel (FR), at least one wing section (FA) is introduced and from the L uftmassenstrom is flowed against, which • is attached to the body arrangement (K) and • has a transverse extension in the form of a span (S), and • this wing section (FA) at least in the direction of its span (S) in the course at least partially the course of the contour the surface (O) of the body arrangement (K) accordingly surrounds, and • over a large part of its span (S) there is a distance (D) to the surface (O) of the body arrangement (K) so that it is on both its underside (US ) - as well as on its upper side (OS) the air can flow around it while driving so that this wing section (FA) with local flow (A) of this air mass flow, which is different from the direction of travel (FR), generates such a resulting flow force (SK) can, which is inclined from its effective direction in the direction of travel (FR) and thus contains a force component (VOR) effective in the direction of travel (FR) so that the force component effective in the direction of travel (FR) onente (VOR) acts on the body arrangement (K) against its resistance force (W) in a propulsive manner.
