PURPOSE: A cooling device of a brake device for a railway vehicle is provided to enhance the frictional performance by stabilizing the frictional coefficient of the brake device to ensure the braking force and thus to enhance the operation stability of a vehicle. CONSTITUTION: A cooling device of a brake device for a railway vehicle comprises a compressed-air spraying unit(100) and a compressed-air feeding unit(200). The compressed-air spraying unit sprays the compressed air to the brake device when the railway vehicle brakes. The compressed-air feeding unit feeds the compressed-air to the compressed-air spraying unit. The compressed-air spraying unit receives the compressed-air from the compressed-air feeding unit and sprays it to a brake disc and a brake pad. The compressed-air spraying unit comprises an air spraying pipe, which sprays the compressed air to the brake disc(11) and the brake pad(10). |
