Railway Fastener Composite Brake Shoe,brake block for locomotive braking
|
Railway Fastener Composite Brake ShoeSpecifications:Our cast iron brake block enjoys many advantages including hardness, impact strength and so on. It consists of two parts, the cast iron and the steel support. Both the surface and core of the cast iron have the hardness within the range of 197< HB< 255.
When facing subsequent impacts to the brake block or brake shoe, the steel support must remain intact and attached to the iron places. The connection bridge may possibly become detached but should not show any soundness defects. Separated from the brake shoe, the support must be able to withstand the bend test with cracking or breaking.

composite brake block
Function brake block features motion to the wheel and well fitness between the brake block and brake block shoe (brake holder).
Physical and mechanical properties of composite
Operational heat Materials organic/inorganic filler and resin bound. Backing plate ST-41 steel plate, and is constructed to transmit the braking force to the composite material. Secondly, there should be a binding structure between the composite material and backing plate, thus forming into a integrated unit and ensuring sufficient bending strength and stiffness.
