Brake disc and method for producing such a brake disc

摘要

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.

主权项

1. A brake disc for vehicles, comprising:
a friction ring, said friction ring comprising a pair of friction strips; a plurality of ribs disposed between and connecting said friction strips; a pot, said pot further comprising a plurality of expansion elements extending outwardly from an outer perimeter of said pot towards said friction ring, said expansion elements connected to said friction ring at an end of said expansion elements opposite from said pot; wherein at least some of said ribs extend radially from said expansion elements; and wherein at least some of said ribs or said expansion elements comprise inserts that are separately formed from said friction strips and connected to said friction strips; wherein said inserts comprise cooling openings along a portion thereof connected to said friction strips; and wherein said cooling openings have one of an elliptical or parallelogram axially elastic shape.
