Product Description
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 stops rotating through friction.
Powder metallurgy materials are made by taking metal powder as a matrix, properly adding friction agent, lubricant and other components, and pressing and controlling high-temperature sintering (900-1050 ºC).
According to the requirements of braking friction performance, powder metallurgy brake shoes are divided into low friction
coefficient brake shoes, standard friction coefficient brake shoes, and high friction coefficient brake shoes.
The brake shoe is composed of a shoe back, steel back, and friction body.The brake shoe back shall be made of steel plate with mechanical properties not lower than Q235.The friction body is made of metal or its alloy as the matrix, added with other metal and non-metal components for friction,friction reduction or some special functions, and sintered with the steel back by powder metallurgy technology.
The brake shoe shall be free of asbestos, lead or its compounds, and other materials that may endanger human health and may produce harmful gases, dust or compounds.
The locomotive powder metallurgy brake shoe has the advantages of high and stable friction coefficient, wear resistance, excellent thermal conductivity, good thermal cracking resistance, and stable friction coefficient in rainy and snowy weather.
