The invention discloses a side apron board of a fully-coated apron board of a bogie for a high-speed motor train unit, the section of the side apron board is L-shaped, and the side apron board comprises a vertical plate and a transverse plate which are connected with each other; the vertical plate is located on the side face of the bogie, and the bottom edge of the vertical plate is not higher than the bottom face of the bogie to completely cover the side face of the bogie. The transverse plate is located on the bottom face of the bogie. By arranging the vertical plates completely covering the side faces of the bogie, airflow is difficult to penetrate through the vertical plates from the outer side to the inner side to enter the bogie in the train running process, and therefore wind resistance can be effectively reduced. And meanwhile, the transverse plate is arranged below the bogie, so that the airflow is difficult to penetrate through the transverse plate from the lower side to the upper side to enter the bogie in the train running process, and the wind resistance can be effectively reduced. Compared with the prior art that the bogie of the train is in an open form or a semi-open form, the covering area of the bogie can be obviously increased, so that the air quantity entering the bogie is reduced, and the effect of reducing the wind resistance is achieved.
本发明公开了一种高速动车组用转向架全包覆裙板之侧部裙板,侧部裙板的断面呈“L”形,其包括相连的立板和横板;立板位于转向架的侧面,其底缘不高于转向架的底面、对转向架的侧面形成完全包覆;横板位于转向架的底面。通过设置对转向架的侧面形成完全包覆的立板,使得气流难以在列车运行过程中从外侧向内侧穿过立板进入转向架,从而能够有效降低风阻。同时,通过在转向架的下方设置横板,也能够使得气流难以在列车运行过程中从下侧向上侧穿过横板进入转向架,亦能有效降低风阻。相对于现有技术中列车的转向架呈开放形式或半开放形式,本发明能够明显增大对转向架的包覆面积,从而减小进入转向架的风量,进而产生降低风阻的效果。
