Description of drawings
Fig. 1 structural representation of the present invention;
The A of Fig. 2 Fig. 1 is to view.
As depicted in figs. 1 and 2, nose cone 1, spoiler 2, driver's cab 3, windscreen 4, inclination angle 5, car body section 6.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As depicted in figs. 1 and 2, high speed train vehicle head structure of the present invention, the monnolithic case of headstock is stream line pattern, helps to reduce air resistance.Particularly, vehicle head structure is divided into four parts, is respectively nose cone 1; Spoiler 2, driver's cab 3 and windscreen 4 all seamlessly transit between each component part; Seamlessly transit between headstock part and the car body section 6; In addition, the headstock bilge construction also comprises and is positioned at driver's cab 3 both sides side wall Shang De lookout window (not shown)s, and structure such as car light (not shown).
Wherein, nose cone 1 is the head of headstock, and the surface of nose cone 1 is a swivel, and it is to be formed by the horizontal rotational shaft of a Bezier around nose cone 1 center.The nose cone 1 that forms like this is point, and wind area is less, in the time of can reducing the vehicle high-speed cruising air-flow to the direct shock zone of headstock portion, and the diffusion district that can reduce generation.
The height h of nose cone 1 distance between center line headstock bottom accounts for the 1/4-1/3 of headstock overall height H, helps to guide most of air-flow into the top of car body, avoids most of air-flow to get into slit, car body bottom and bogie truck zone, thereby effectively reduces air resistance.
The spoiler 2 of one plow-shape is set below nose cone 1, and spoiler 2 profiles and the nose cone 1 of plow-shape are complementary, and help to slow down the flow velocity of nose cone 1 below gas.The lower surface of nose cone 1 and flame diversion trough structure of spoiler 2 common compositions; This flow-guiding structure is a flame diversion trough structure to lower recess; It can directed flow cross the both sides discharge of the air of nose cone 1 bottom by car body; Rather than discharge by the bottom of car body, like this, can further reduce the aerodynamic drag of car load.
