Cast Iron anchor brake shoe / Composite Brake Block for Locomotive Part

Brief introduction

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.

Material Character

The materials of composite brake block consist of 3 main substances including reinforcing fiber, organic/inorganic filler and resin bound. It has a high level of uniformity. It can be separated from the backing plate. It contains no asbestos, lead, zinc or other mixtures. It also contains no toxic materials. The hardness of the material is lower than the wheel\'s. It causes no strong smell in friction.

Backing plate

Backing plate for a trains\' composite brake block must meet the following criteria. Firstly, it is made of 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.
