Railway Brake Disc Casting Iron Axle Type Brake Disc Railway Passenger Coach 160 km/h

1. Brief introduction:

Railway vehicles use two main kinds of braking systems: brake shoe brakes and brake disc brakes. Brake discs can be categorized based on their mounting location; there are wheel type brake discs and axle type brake discs.
Axle type brake discs are positioned on the axle, situated between two wheels of the same wheel set. During braking, the brake pads make contact with the brake disc, converting kinetic energy into thermal energy through the friction generated between them.
Brake discs come in two forms: mono block and twin block. Twin block brake discs are divided into two halves, making them simpler to replace when they wear down. The main components of a brake disc include the disc body, hub, disc hoop, bolts, washers, and other parts.

2. Main structural features:

•  The disc hub and the disc body is connected by floating connection;
• The braking torque is overcome by elastic pin, improving the reliability of connecting bolts;
• Heat dissipation ribs are designed on the disc body and has good ventilation and thermal dissipation;
• Adopt self-locking nuts with embedded materials to ensure the nuts would not loosen;
• Flanging washer is added between each two groups for interlocking of nuts;
