Drag reduction device between carriages of high-speed multiple units

Abstract

The present invention provides a drag reduction device between carriages of high-speed multiple units for reducing air drag, which belongs to the technical field of railway carriages. The technical solution of the present invention is as follows: a drag reduction device between carriages of high-speed multiple units comprises side windshields arranged on side edges of each end wall of a carriage body. Each of the side windshields includes a bar rubber capsule and a rubber capsule frame whose shapes are matched with a curve of the side edge of the end wall of the carriage body. The rubber capsule is connected with the end wall of the carriage body by the rubber capsule frame. The device is simple in structure, convenient and quick to install, and the multiple units need not to be broken up or made up. Furthermore, the device can effectively reduce the air drag resulting from the impact of the airflow on the end wall of the carriage body and increase the running speed of the train.

1 . A drag reduction device between carriages of high-speed multiple units, comprising side windshields ( 1 ) arranged on side edges of each end wall of a carriage body, wherein each of the side windshields ( 1 ) includes a bar rubber capsule ( 5 ) and a rubber capsule frame ( 4 ) whose shapes are matched with a curve of the side edge of the end wall of the carriage body, and the bar rubber capsule ( 5 ) is connected with the end wall of the carriage body by the rubber capsule frame ( 4 ). 
     
     
         2 . The drag reduction device between carriages of high-speed multiple units according to  claim 1 , further comprising a top guide plate ( 3 ) fixed on an upper edge of the end wall of the carriage body, wherein a radian of the top guide plate ( 3 ) is matched with a radian of a roof plate of the carriage body, the top guide plate ( 3 ) is in butt joint with the roof plate of the carriage body, and two ends of the top guide plate are in butt joint with the side windshields ( 1 ). 
     
     
         3 . The drag reduction device between carriages of high-speed multiple units according to  claim 1 , further comprising a bottom guide plate ( 2 ) below each of the side windshields ( 1 ), wherein a radian of the bottom guide plate ( 2 ) is matched with a radian of a lower skirt edge of the carriage body, the bottom guide plate ( 2 ) is fixed on an underframe of the carriage by a bottom guide plate bracket ( 6 ), and an upper end of the bottom guide plate ( 2 ) is in butt joint with the corresponding side windshield ( 1 ). 
     
     
         4 . The drag reduction device between carriages of high-speed multiple units according to  claim 2 , further comprising a bottom guide plate ( 2 ) below each of the side windshields ( 1 ), wherein a radian of the bottom guide plate ( 2 ) is matched with a radian of a lower skirt edge of the carriage body, the bottom guide plate ( 2 ) is fixed on an underframe of the carriage by a bottom guide plate bracket ( 6 ), and an upper end of the bottom guide plate ( 2 ) is in butt joint with the corresponding side windshield ( 1 ).
