1. A disc brake for a vehicle, the disc brake comprising:
a first brake pad (2a) and a second brake pad (2b);
a brake disc (1) disposed between the first brake pad (2a) and the second brake pad (2b);
a brake caliper engaging over the brake disc (1) and comprising a brake caliper housing (6);
a tensioning installation disposed in the brake caliper housing (6) and comprising a compression piece (3) configured to be tensioned in relation to the first brake pad (2a);
a sheet metal arrangement (7) comprised of a sheet metal plate (8) and a sheet metal ring (9) disposed coaxially to the sheet metal plate (8) and connected to the sheet metal plate (8) in a materially integral manner;
a bellows (5) configured to protect an interior of the brake caliper housing (6) against contamination, wherein the bellows (5) comprises a first end region (5a) fastened to the brake caliper housing (6) and further comprises a second end region (5b) fastened to the sheet metal arrangement (7);
wherein the sheet metal plate (8) is disposed between an end side of the compression piece (3) and the first brake pad (2a);
wherein the sheet metal ring (9) is disposed between the bellows (5) and the brake pad (2a) so as to protect the bellows (5) against thermal radiation generated at the first and second brake pads (2a, 2b) and the brake disc (1) by a braking action;
wherein the sheet metal ring (9) comprises an annular disc-shaped portion (9b) disposed in a radial extension of the sheet metal plate (8), wherein the annular disc-shaped portion (9b) comprises cutouts (11) in the shape of elongate slots to reduce a flexural stiffness of the sheet metal ring (9);
wherein the cutouts (11) are uniformly distributed on the annular disc-shaped portion (9b) in a circumferential direction of the annular disc-shaped portion (9b) and are arranged adjacent to each other on at least one circular path; and
a disc (13) disposed on the annular disc-shaped portion (9b) and arranged between the second end region (5b) of the bellows (5) and the annular disc-shaped portion (9b), wherein the disc (13) has a non-stick effect.
