Low Friction Train Wheel Composite Brake Block Cast Iron / Locomotive Brake Shoe 

Shanghai SUYU Railway Material Co., Ltd. manufactures both high-friction and low-friction composition brake shoes, specialty shoes, and disc brake linings for freight, locomotive and transit vehicles.

SUYU brake shoes were developed to address the problem of wheel removals due to shelling, spalling, and high impacts.

As value-added brake shoe with a cast iron insert, it provides the following benefits for a wide range of freight car and locomotive applications:
 

1. continuously removes minor tread damage

2. minimizes removal of wheels for repair

3. prolongs life cycle of wheels

4. reduces downtime

5. reduces wheel set inventory

6. reduces wheel changeouts

Compo brake block

Compo brake block is a rigid moulded friction material, grey-black in colour, having a random fibre asbestos base and containing metallic particles. It is manufactured only in the form of brake blocks, integrally moulded to a back plate. This material was originally developed to have the ability to withstand the heavy braking demands of Electric Multiple Unit (EMU) stock, operating suburban passenger services. Its use has since been extended to a range of duties from low speed shunting locomotives to high speed passenger trains.

It has a higher and more stable coefficient of friction than the conventional cast iron block which it replaces, resulting in lower application forces and permitting the use of smaller cylinders. It is a conformable block designed to eliminate thermal cracking of tyres, which had hitherto been a barrier to the widespread use of composition blocks. SUYU Block has several fold advantages in life over cast iron blocks and thus significantly lengthens service periods. It is particularly beneficial in those situations where hot cast iron dust would present a safety hazard. Spark-free blocks are essential in oil refineries, chemical works and ordinance factories. The composition block has much to offer in the braking of passenger rail, minimising braking shocks by its smoother action and permitting higher load/tare factor.
