Brake disc and method for producing such a brake disc

Abstract

The invention relates to a brake disc (8) having a friction ring (10) made of a frictional pair (11a, 11b) connected to each other by means of ribs (4), having a pot (9) and expansion elements (2) disposed radially to the pot (9), preferably at the outer circumference of the pot (9), and the ends thereof facing away from the pot (9) are connected to the friction ring (10). At least one expansion element (2) at least partially forms a rib (4) for connecting the friction pair (11a, 11b). The invention further relates to a method for producing such a brake disc (8), wherein expansion elements (2) are connected by casting to a friction ring (10) and/or to a pot (9). The friction ring (10) and/or the pot (9) comprise at least one protective element after being connected, wherein the friction ring (10) and/or the pot (9) is cast in a single piece with the protective element.
