BRAKE DISC FOR RAILROAD VEHICLE

A brake disc (100) includes a disc body (10) and fins (20). The disc body (10) decreases in thickness as the disc body extends inward in a radial direction. The fins (20) are radially disposed on a back surface (12) of the disc body (10). At least one of the fins (20) has a bolt hole (22) at a centr...

Zusammenfassung:	A brake disc (100) includes a disc body (10) and fins (20). The disc body (10) decreases in thickness as the disc body extends inward in a radial direction. The fins (20) are radially disposed on a back surface (12) of the disc body (10). At least one of the fins (20) has a bolt hole (22) at a central portion of the fin (20) in the radial direction. The disc body (10) includes projections (13). The projections (13) are formed on a portion of the back surface (12) positioned outward from the bolt hole (22) in the radial direction. The fins (20) each include a top surface (21) and a convex portion (25). The convex portion (25) protrudes inward from an imaginary plane (S 1) in the radial direction. The imaginary plane (S 1) passes an end portion (212) of the top surface (21) and an inner circumferential edge (122) of the back surface (12).
