The brake shoe is the brake part that directly rubs the wheels to stop the train when the train is running and braking. Shoe-shaped brake pads made of cast iron or other materials hold the wheel tread tightly when braking, and stop the wheel from turning through friction. In this process, the braking device converts the huge kinetic energy into heat energy and dissipates it into the atmosphere. The quality of this braking effect mainly depends on the ability to dissipate frictional heat energy. When using this braking method, the friction area of the brake shoe is small, and most of the thermal load is borne by the wheel. The higher the train speed, the greater the thermal load on the wheels when braking. If cast iron brake shoes are used, the temperature can melt the brake shoes; even if more advanced synthetic brake shoes are used, the temperature will be as high as 400~450℃. When the temperature of the wheel tread increases to a certain extent, the tread will be worn, cracked or peeled off, which affects both the service life and the driving safety. It can be seen that the traditional tread brake shoe braking cannot meet the needs of high-speed trains.
