Durable Synthetic Railway Braking System Composite Brake Blocks For Railways Wagon For 80-120km/Hour
Product Overview
When the train is running and braking, the brake part that directly rubs the wheel to stop the train is the brake shoe; the tile shaped brake block made of cast iron,composite material or other materials holds the wheel tread tightly and makes the wheel stop rotating through friction.
Railway brake shoe other name is railway brake block, train brake block. It is mainly used for the braking of heavy-duty freight cars. It is applicable to railway freight cars with maximum running speed of 120km/h and axle load of no more than 25t.
Composite brake shoes for railway freight cars are divided into two types: one is high friction coefficient composite brake shoe(H), and the other is low friction coefficient composite brake shoe(L). “H” brake shoe cannot be interchanged with “L” brake shoe and various cast iron brake shoes.

2. Powder treated brake shoe
Powder metallurgy brake shoe is made of metal or alloy as the matrix, added with friction, lubrication or other metals and nonmetals with some special functions, and made by powder metallurgy technology. Its quality is between high wear synthetic and cast iron brake shoes. It forms black powder after wearing with the locomotive wheel tread, which will not cause major damage to the locomotive wheel tread.
