China Factory Train Bogie Part Braking System Composite/High Phosphorus Cast Iron/Powder Metallurgical Brake Shoe for Railway

The brake shoe is the critical component in a train's braking system that directly rubs against the wheel to create friction and stop the vehicle. These tile-shaped blocks, made from cast iron, composite materials, or powder metallurgy, hold the wheel tread tightly to convert kinetic energy into thermal energy.

Commonly referred to as railway brake blocks or train brake blocks, they are primarily utilized for heavy-duty freight cars, passenger cars, and locomotives with speeds up to 120km/h and axle loads up to 25t.

Composite brake shoes are classified into two specific types: High friction coefficient (H) and Low friction coefficient (L). Note: "H" type shoes are not interchangeable with "L" type or traditional cast iron variants.

Manufactured using metal powder as a matrix with added friction agents and lubricants, these are processed through high-temperature sintering (900-1050 ºC). They are available in low, standard, and high friction coefficient versions to meet diverse braking requirements.
