Abstract

The invention discloses a bogie rectifying device capable of overcoming the airflow resistance and relates to the technical field of train belly rectification. The bogie rectifying device capable of overcoming the airflow resistance comprises a fairwater cone rail, fairwater cone wheels, a shell frame, access doors, a fairwater cone shell, a carriage underbody, a bogie, a guide wheel bracket, a guide wheel and a steel rail, and is characterized in that the fairwater cone shell covers the bogie; the upper and lower parts of the fairwater cone shell are provided with openings; the front and rear surfaces of the fairwater cone shell are arc surfaces; baffle plates on two sides of the fairwater cone shell are provided with the access doors; the two sides of the exteriors of the upper ends on the front and rear surfaces of the fairwater cone shell are provided with the fairwater cone wheels; the fairwater cone shell is connected with the fairwater cone rail by virtue of the fairwater cone wheels; the fairwater cone rail is connected with the carriage underbody by virtue of welding; a shell frame is welded and connected in the fairwater cone shell; a transverse rack at the lower end of the shell frame is connected with the guide wheel bracket; and the guide wheel is connected with the guide wheel bracket. The bogie rectifying device has the characteristics of reducing the air resistance of train running, reducing the energy consumption and improving the running speed.

Description

technical field [0001] A bogie rectification device for overcoming airflow resistance relates to the technical field of train belly rectification. Background technique [0002] Modern trains are constantly developing towards high-speed comfort. The resistance of trains mainly comes from the frictional resistance of wheels and rails, and the hydrodynamic resistance of airflow to trains. In order to overcome the resistance of the air flow to the running train, there is a skirt connected under the train car, but there is no skirt around the bogie of the train. The skirt will hinder the rotation of the bogie. Chinese patent application: 200810195674.6 proposes a technical solution for high-speed train belly rectification, but the feasibility is poor due to insufficient disclosure. First, according to the technical feature of claim 2: "a flat-plate beam fairing is installed under the belly beam", which blocks the braking of the wheels on the bogie by the train braking device; s...
