Vehicle having a cross-sectionally reduced portion

Abstract

A vehicle has at least one cross-sectionally reduced portion. At least one air-guiding element is arranged in the cross-sectionally reduced portion and extends outwards in the vehicle transverse direction and causes an airflow guidance of an airflow that enters the cross-sectionally reduced portion during travel, and does so in such a way that a part of the airflow is guided from the inside back to the outside and at the same time is deflected obliquely downwards.

         16 . A vehicle, comprising:
 at least one cross-sectionally reduced portion; and   at least one air-guiding element disposed in said cross-sectionally reduced portion and extending outward in a transverse direction of the vehicle and causes an airflow guidance of an airflow which enters said cross-sectionally reduced portion during travel, such that a part of the airflow being guided from an inside back to an outside and at a same time is deflected obliquely downward.   
     
     
         17 . The vehicle according to  claim 16 , wherein said at least one air-guiding element at least in its outer end area is oriented obliquely downward. 
     
     
         18 . The vehicle according to  claim 16 , further comprising an air supply element disposed at an edge of said cross-sectionally reduced portion, said air-supply element having a longitudinal direction extending vertically or at least predominantly vertically and whose outer contour brings about a horizontal airflow supply into said cross-sectionally reduced portion during travel, wherein the horizontal airflow supply causes the airflow, or at least supports the airflow. 
     
     
         19 . The vehicle according to  claim 18 , wherein said at least one air-guiding element is disposed in terms of height in a central area between an upper end of said air-supply element and a lower end of said air-supply element and segments said at least one cross-sectionally reduced portion into an upper flow portion with an upward flow direction of the airflow and into a lower flow portion with a downward flow direction of the airflow. 
     
     
         20 . The vehicle according to  claim 18 , wherein said at least one air-guiding element is disposed in an area of an upper end of said air-supply element or above said air-supply element and segments said at least one cross-sectionally reduced portion into an upper flow portion with an upward or horizontal flow direction of the airflow and into a lower flow portion with a downward flow direction of the airflow. 
     
     
         21 . The vehicle according to  claim 18 , further comprising two cars which are coupled together to form an inter-car area, said inter-car area forming said at least one cross-sectionally reduced portion and said at least one air-guiding element is disposed on a car end face of one of said cars facing said inter-car area and said air-supply element is formed by a shape of a side wall portion of a same said one of said cars adjacent to said inter-car area. 
     
     
         22 . The vehicle according to  claim 21 , wherein said at least one air-guiding element and said air-supply element interact during travel in a direction of travel in which one of said cars equipped with said at least one air-guiding element and said air-supply element is at a front, such that a portion of the airflow supplied horizontally by said air-supply element below said at least one air-guiding element is guided outward by said at least one air-guiding element with a horizontally outward directional component and a vertically downward directional component. 
     
     
         23 . The vehicle according to  claim 21 , wherein said at least one air-guiding element is one of at least two air-guiding elements which are disposed at a distance from one another on at least one of said two cars being coupled cars, wherein said at least two air-guiding elements are spatially separated from one another by a central axis of the vehicle. 
     
     
         24 . The vehicle according to  claim 21 , wherein:
 said at least one air-guiding element includes a first air-guiding element and a second air-guiding element;   said air-supply element includes a first air-supply element and a second air-supply element;   each of said two cars has said first air-guiding element and said first air-supply element interacting with said first air-guiding element as well as said second air-guiding element and said second air-supply element interacting with said second air-guiding element; and   said first air-guiding elements and said first air-supply elements are separated from said second air-guiding elements and said second air-supply elements by a center of the vehicle.   
     
     
         25 . The vehicle according to  claim 16 , wherein said at least one air-guiding element is trough-shaped. 
     
     
         26 . The vehicle according to  claim 16 , wherein said at least one air-guiding element is formed by a sheet metal part bent several times. 
     
     
         27 . The vehicle according to  claim 21 , further comprising at least one retaining element, said at least one air-guiding element is attached to said car end face of said car facing said inter-car area and is held there by said at least one retaining element which is attached to an upper side of said at least one air-guiding element and said at least one retaining element is fastened to said car end face above said at least one air-guiding element. 
     
     
         28 . The vehicle according to  claim 18 , wherein said air-supply element, viewed in cross-section from above, has a curved outer contour which is curved inward in a direction of said at least one cross-sectionally reduced portion and due to said curved outer contour causes a horizontal, stall-free deflection of the airflow into said at least one cross-sectionally reduced portion. 
     
     
         29 . The vehicle according to  claim 18 , wherein said air-supply element is formed by an inwardly curved outer skin area of the vehicle. 
     
     
         30 . The vehicle according to  claim 18 , wherein said air-supply element is formed by an extruded profile part or a sheet metal part. 
     
     
         31 . The vehicle according to  claim 24 , further comprising a walkable car transition area disposed in said center of the vehicle.
