BRAKE DISC FOR A DISC BRAKING SYSTEM

摘要

The invention relates to a brake disc (1) for a disc braking system, especially for use in utility vehicles. Said brake disc (1) has a thickness (D1) with two friction plates (3, 4) disposed parallel to each other, between which an airflow duct (5) with a width (D2) is located in a substantially central position. The brake disc (1) is made of a gray cast iron material containing molybdene. The ratio of the disc thickness (D1) to the airflow duct width (D2) meets the requirement 3,2
