| description | The utility model belongs to the field of high-speed trains, and particularly relates to a cowcatcher for diversion and resistance reduction of a high-speed train bogie, the cowcatcher is used for being arranged at the bottom of the front end of a train head of the high-speed train, the cowcatcher comprises a cowcatcher body, and the section of the bottom surface of the cowcatcher body in the length direction of the train head is in a wave shape. According to the cowcatcher, the bottom of the cowcatcher body is arranged to be in the wave-shaped outline, disturbance on a shearing layer is increased, the situation of airflow flowing through the vehicle bottom is improved, direct impact of the airflow on the bogie wheel bottom and the rear end of a bogie cabin is reduced, airflow separation on the two sides of the bogie wheel bottom is reduced, and the service life of the bogie is prolonged. Aerodynamic resistance generated when the high-speed train runs is reduced, and therefore the running efficiency of the hi |
