How does the train brake?
As an important means of transportation, the train's braking system is the key to ensuring safe operation. This article will introduce the principles, types and related technologies of train braking in detail, and present you with a structured content based on hot topics in the past 10 days.
1. Basic principles of train brakes
The braking system of trains mainly relies on friction and air pressure. When the driver operates the brakes, the system will transmit the braking instructions to each car through a series of mechanical or electrical signals, and finally decelerate or stop through the friction between the brake pads and the wheels or tracks.
2. Types of train brakes
The braking system of trains is mainly divided into the following types:
| Brake type | Working principle | Applicable scenarios |
|---|---|---|
| air brake | Controlling brake pad pressure with compressed air | traditional railway train |
| Electric braking | Utilize motor reversal to generate resistance | High-speed rail, EMU |
| Magnetic braking | friction generated by electromagnetic force | high speed train |
| hydraulic brake | Using hydraulic oil to transmit pressure | Some special vehicles |
