Problems solved by technology

[0003] Due to the gap between the ends of the two adjacent vehicles of the high-speed EMU, when the EMU is running (speed greater than 200km / h), the air flow will be shunted and disturbed when it hits the end wall of the car body, which will increase the air resistance.

Embodiment Construction

[0023] see figure 1 , figure 2 , the present invention comprises three parts of the vehicle-to-vehicle top deflector 3, the bottom deflector 2, and the side windshield 1. By increasing the side windshield 1, the vehicle body can be streamlined, reducing airflow disturbance and reducing air resistance; by increasing the top deflector 3 and the bottom deflector 2, the distance between vehicles can be shortened and air diversion can be reduced.

[0024] see image 3 , Figure 4 , the top deflector 3 is welded by aluminum plate, and is installed on the roof by bolts.

[0025] see Figure 5 ~ Figure 7 , The side windshield 1 is composed of a capsule frame 4 and a rubber capsule 5, and the rubber capsule 5 is fixed on the capsule frame 4 by bolts. The capsule frame 4 is installed on the car body end wall by bolts. After the vehicle is connected, the rubber capsules 5 of the two side windshields are closely attached to make the appearance of the vehicle body streamlined, reduc...

Abstract

A device for reducing drag between high-speed multiple unit trains belongs to the technical field of railway carriages and is used for reducing air drag. The technical scheme of the device is as follows: the device for reducing drag between high-speed multiple unit trains comprises side windshields which are arranged at sides of each train body end wall, each side windshield comprises a strip rubber bag and a rubber bag frame, the shape of the strip rubber bags is matched with arc lines of the sides of the train body end walls, and the rubber bags are connected with the train body end walls bythe rubber bag frames. The device has simple structure and convenient and rapid installation, the multiple units need not to be broken up or made up, and the device can greatly reduce the air drag which is generated as air flow impacts the train body end walls, thus increasing the running speed of trains.

Description

technical field [0001] The invention relates to a device installed between two vehicles of a high-speed EMU for reducing air resistance and increasing running speed, which belongs to the technical field of railway passenger cars. Background technique [0002] When the running speed of an ordinary train is 120km / h, the air resistance of the train accounts for 40% of the total resistance, and when the running speed is 160km / h, the air resistance accounts for 70% of the total resistance. Since the air resistance of the train is proportional to the square of the train running speed, increasing the running speed of the train requires reducing the air resistance of the train. The factors that affect the air resistance of the train include the running speed, the shape of the head of the car body, the shape of the car body, and the structural form of the car end. [0003] Due to the gap between the ends of the two adjacent vehicles of the high-speed EMU, when the EMU is running (sp...
