Problems solved by technology
Any capture of changes in surface area - often difficult to control - can lead to unfavorable profile travel directions
[0018] Overall, therefore, the manufacture of brake discs with a sufficiently strong coating applied by heat leaves room for improvement

Embodiment Construction
[0131] In the various figures, identical components always bear the same reference numerals so that these are usually only described once.
[0132] figure 1 is a schematic depiction of a brake disk 1 according to the invention before it is coated, at least in regions. This has a circular base body 2 that extends as a body of revolution that rotates symmetrically about the axis of rotation a. The base body 2 is preferably made of cast iron (gray cast iron). The base body 2 has a peripheral outer friction ring 3 which is provided for contact with brake pads of a brake caliper (not shown in more detail). In the center of the base body 2 is the opening 4, which in the figure 2 is clearly and visibly arranged in the raised portion 5 of the base body 2 .
[0133] In the present case, five through-holes 6 are arranged at equal distances around the opening 4 through the raised portion 5 . Said through holes 6 are used to accommodate wheel bolts, not shown here, by means of which...

Abstract
The present invention relates to a method for making a brake disc (1) used for a vehicle. The brake disc (1) comprises a base (2), and the base (2) is coated with a surface area (10). The method comprises the following steps: a concave part (11, 12) in which a ribbed plate (13) is holded is manufactured in the surface area (10), and the concave part (11, 12) is manufactured in the surface area (10) of the base (2) in a groove (14) manner; the deformation of the ribbed plate (13) enables the ribbed plate (13) to at least plastically move in at least one undercut (32) part facing the concave part (11, 12); and a coating (40) is applied to the surface area (10). In order to form the undercut (32) and to form an amboss (36) on an end surface (35) of the ribbed plate (13), the ribbed plate (13) is rolled by a roller body (15) at least partially configured to be a truncated cone; the ratio of the small perimeter (20) of the roller body (15) to the inner perimeter (22) of the surface area (10) corresponds to the ratio of the large perimeter (21) of the roller body (15) to the outer perimeter (23) of the surface area (10), wherein the outer housing surface of the roller body (15) configured to be a truncated cone is guided to be the surface area (10) parallel to the base (2). Furthermore, the purpose of the invention is a brake disc (1) manufactured by the method.
Description
technical field [0001] The invention relates to a method of manufacturing a brake disc for a vehicle, as well as a brake disc for a vehicle. Background technique [0002] In vehicles, especially motor vehicles, disc brakes are by far the most common type of braking system. Disc brakes essentially consist of a disc and a caliper that surrounds the disc on the rim. The brake disc is connected to the wheel of the vehicle to be braked via a hub rotatably mounted on the steering shaft. In contrast, brake calipers are fixed to the steering shaft. The actual deceleration is achieved by means of brake pads which can abut against both sides of the disc placed on the brake disc and arranged between it and the caliper. [0003] Depending on the application, the brake discs can consist of iron or also carbon ceramic or aluminum. The brake disc should have a surface that is as wear-resistant as possible and emits as little dust as possible. To achieve this, the surface should be as ...
