Abstract

A brake disk device for a vehicle having an annular brake disk with an encircling outer portion and an encircling inner portion, the inner diameter of which bounds a disk opening, and a brake pot with an annularly encircling edge portion, wherein the brake pot is fastened at the edge portion to the inner portion of the brake disk, wherein the edge portion is of multi-layered design at least in sections and/or is of thickened design in sections, wherein the walls of the edge portion are at least partially in contact, and an inner surface of the edge portion is designed as an additional brake surface.

First claim

What is claimed is:

1 . A brake disk device for a vehicle comprising:
an annular brake disk with an encircling outer portion and an encircling inner portion, an inner diameter of the encircling inner portion bounds a disk opening, and a brake pot with an annularly encircling edge portion, wherein the brake pot is fastened at the annularly encircling edge portion to the encircling inner portion of the brake disk, wherein the annularly encircling edge portion is multi-layered at least in sections and/or is cold-formed and thickened in sections, wherein walls of the annularly encircling edge portion are at least partially in contact, and an inner surface of the annularly encircling edge portion is an additional brake surface.

2 . The brake disk device as claimed in claim 1 , wherein the annularly encircling edge portion has, at least in sections, a wall which is bent over and is in contact with itself.

3 . The brake disk device as claimed in claim 1 , wherein the annularly encircling edge portion has a double-walled design that is formed by at least one cold-forming step.

4 . The brake disk device as claimed in claim 3 , wherein the two walls of the double-walled annularly encircling edge portion are connected to each other in an integrally bonded manner.

5 . The brake disk device as claimed in claim 1 , wherein the brake pot has a base which is closed at least in sections.

6 . The brake disk device as claimed in claim 1 , wherein the additional brake surface has, at least in sections, a machined brake surface and/or a brake pad fastened in an exchangeable manner.

7 . The brake disk device as claimed in claim 1 , wherein the annularly encircling edge portion has an encircling flanged edge which extends radially or substantially radially outward and forms a fastening form-fitting connection with the encircling inner portion of the brake disk.

8 . A method for producing the brake disk device with the features of claim 1 , having the following steps:
arranging the brake pot in the disk opening of the brake disk, forming the edge portion, which is multi-layered at least in sections and/or is thickened in sections, on the brake pot, fastening the edge portion to the inner portion of the brake disk.

9 . The method as claimed in claim 8 , wherein the edge portion of the brake pot is produced by being bent over.

10 . The method as claimed in claim 8 , wherein a flanged edge is formed on the edge portion for form-fitting fastening to the inner portion of the brake disk.
