The "three-piece set" and "five still need" of the high-speed rail suspension.

Recently, the country has experienced another small outbreak of the epidemic, with the Omicron variant spreading faster and wider. Here, Nuoguan calls on everyone

to persist"three-piece set" and "five musts", always pay attention to your own and your family's health and safety.

A video has been circulating on the internet, showing a Swedish passenger traveling on the Beijing-Shanghai high-speed train. During the journey, he stood a coin on

the train window sill, and the train was traveling at about 300 kilometers per hour. The coin stood upright for more than eight minutes. Once this video was released,

it attracted global attention to the stability of China's high-speed rail.

However, for those familiar with China's high-speed rail, this is taken for granted. The comfort is supported by infrastructure, tracks,

vehicles, operations, and many other aspects,and it relies on key leading technologies, including millimeter-level track flatness,

intelligent adjustable bogie secondary suspension, etc.

The suspension device is a general term for all force transmission connection devices between the frame and the axle or wheels, responsible for transmitting the forces and moments acting between the wheels and the frame,

and buffering the impact force transmitted to the frame or body from uneven road surfaces, and attenuating the vibrations caused by it,

to ensure the vehicle runs smoothly.

The secondary suspension mainly consists of air spring suspension systems, traction devices, lateral dampers, anti-sway dampers, and lateral buffer rubber stops.

It is the adoption of the air spring suspension system that significantly improves the operational stability of the vehicle system,

greatly simplifies the structure of the bogie, making the bogie lightweight and easy to maintain. The air spring suspension system mainly consists of air springs,

height adjustment valves, pressure difference valves, average valves, etc.
