High Brake Shoe of Braking System part for Train Bogie   

‌

‌What is a Brake Shoe?‌
When a train slows down or stops, the brake shoe presses against the wheel to create friction. Made of cast iron, composites, or other materials, it comes in tile-shaped blocks that grip the wheel tread to halt rotation.

‌Types of Brake Shoes‌

1. ‌Composite Brake Shoes‌

   • ‌High-friction (H)‌: Cannot be mixed with low-friction (L) or cast iron shoes.
   • ‌Low-friction (L)‌: Designed for specific speed and load conditions.

2. ‌Powder Metallurgy Brake Shoes‌

   • Made by pressing metal powder with additives, then sintering at high temperatures.
   • Classified by friction level: low, standard, or high.

Key Advantages‌

• ‌Friction Performance‌:

  • High phosphorus content (2.0–2.5%) ensures stable braking force across speeds.
  • Wear resistance is 2.5x longer than standard shoes, reducing maintenance.

• ‌Safety‌:

  • Fewer sparks, lowering fire risks in flammable areas.
  • Stronger and more durable, preventing fractures at high speeds.

• ‌Other Benefits‌:

  • Efficient heat dissipation protects wheels and braking systems.
  • Eco-friendly with recyclable materials.
  • Cost-effective to produce using standard methods.

‌Ideal for‌: Freight trains with speeds up to 120 km/h and axle loads ≤25 tons.
