Disk Brake Comprising Brake Disk Rings Made of Brittle Material and Vehicle Fitted With One or Several Disk Brakes of Said Type

A disc brake (1) for a wheel, characterized in that a support device (17), consisting of an inner rim (4) of stainless steel with an intermediate ring (6) of light metal riveted or screwed thereon is flush-riveted together with a brake disc ring (2) of brittle material, for example ceramic, wherein the brake disc ring (2) on the radial inner side has receiving holes (18) with counterbores (18.1) for countersunk rivets (3) of stainless steel on the disc outer side facing away from the wheel and that the disc material enclosing these holes (18) on the inside is formed with a constant cross section and without constrictions.

The disc brake (1) according to claim 1, wherein for riveting inner rim (4) to brake disc ring (2) countersunk rivets (3) of stainless steel are used which slightly protrude at the counterbore (18.1), i.e. approximately 0.5 mm over the brake disc ring (2).

The disc brake (1) according to claim 1, wherein the inner rim (4) of stainless steel comprises two star-shaped flat spokes (20) at a preferably flat angle with respect to each other towards each receiving hole (18), which at the juncture have a counter hole (21) fitting the receiving hole and on the hub side merge with a ring (22) adapted to the wheel rim,

• and the material thickness of this inner rim (4) is selected so that a resilience of the flat spokes (20) in lateral or axial direction is guaranteed.

The disc brake (1) according to claim 1, wherein the intermediate ring (6) riveted or screwed to the inner rim (4) can be re-machined on a side (12) parallel to the brake disc ring surface (13),

• to achieve adaptation without runout including screw connection (7) to a rim of a wheel.

A vehicle (14) comprising at least one disc brake (8, 9) in accordance with claim 1.
