High Quality Subway Light Rail Axle Mounted Disc Brake

Product Description

Brake disc is a core component of the vehicle braking system, primarily used to decelerate or stop a vehicle through friction. Typically, it is a flat, circular metal plate mounted on the wheel. The brake pads press against the brake disc via calipers to generate friction, thereby achieving braking.

Performance Requirements

1. Braking Performance: In emergency braking mode, the deceleration and temperature rise rate of the brake disc are key performance indicators. For example, the maximum temperature of the brake disc surface during emergency braking can reach 941.4°C, with an emergency braking distance up to 6726 meters for carbon ceramic brake discs.
2. Residual Imbalance: The residual imbalance of the brake disc must be matched with the speed grade.
3. Fatigue Performance: The brake disc must pass 1:1 braking dynamometer tests and fatigue tests to ensure long-term reliability.
