摘要： 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.
