Abstract

A brake rotor, includes at least one friction element and one adapter element, wherein the brake rotor is configured to rotate about an axis of rotation, wherein the friction element has at least one friction surface and one connection region, wherein the adapter element has an installation region and a transfer region, wherein the installation region is configured for fixing the brake rotor to a hub, wherein the connection region indirectly or directly engages in positively locking fashion in a circumferential direction with the transfer region such that a torque about the axis of rotation can be transferred between the connection region and the transfer region from the friction element to the adapter element.

First claim

wherein the installation region is configured to fix the brake rotor to a hub;
wherein the connection region indirectly or directly engages in positively locking fashion in a circumferential direction with the transfer region such that a torque about the axis of rotation can be transferred between the connection region and the transfer region from the friction element to the adapter element; and
wherein the adapter element is of multi-part form in the circumferential direction.

2. The brake rotor as claimed in claim 1 , wherein the connection region includes at least three connection portions, and wherein the transfer region includes at least three complementary transfer portions.

3. The brake rotor as claimed in claim 2 , wherein each of the connection portions exhibit play in a radial direction in relation to a respective one of complementary transfer portions.

4. The brake rotor as claimed in claim 3 , wherein the connection portions extend in the axial direction proceeding from an axial face surface of the friction element, and/or wherein the transfer portions extend in the axial direction proceeding from an axial face surface of the adapter element.

5. The brake rotor as claimed in claim 4 , wherein reinforcement elements are arranged on the connection portions and/or the transfer portions.

6. The brake rotor as claimed in claim 5 , wherein at least one of the connection portions forms a radially inwardly open contour on the axial face surface of the friction element, and/or wherein at least one of the transfer portions forms a radially outwardly open contour on the axial face surface of the adapter element.

7. The brake rotor as claimed in claim 1 , wherein the connection region includes at least one connection portion, and wherein the transfer region includes at least one complementary transfer portions.

8. The brake rotor as claimed in claim 7 , wherein the at least one connection portion exhibits play in a radial direction in relation to the at least one complementary transfer portion.

9. The brake rotor as claimed in claim 7 , wherein the at least one connection portion extends in the axial direction proceeding from an axial face surface of the friction element, and/or wherein the at least one transfer portion extends in the axial direction proceeding from an axial face surface of the adapter element.

10. The brake rotor as claimed in claim 7 , wherein at least one reinforcement element is arranged on the at least one connection portion and/or the at least one transfer portion.

11. The brake rotor as claimed in claim 7 , wherein the at least one of the connection portion forms a radially inwardly open contour on the axial face surface of the friction element, and/or wherein the at least one of the transfer portion forms a radially outwardly open contour on the axial face surface of the adapter element.

12. The brake rotor as claimed in claim 1 , wherein the adapter element is reversibly clamped axially to the friction element by a fastener.
