Brake disk for motor vehicle has friction ring with polygonal inner contour and attachment body with corresponding outer contour for shape-locking connection to friction ring

摘要

The brake disk has a friction ring (1), an attachment body (2), especially a pot-shaped brake disk body or a wheel hub, and connecting elements between the friction ring and attachment body. The friction ring has a polygonal inner contour and the attachment body has a correspondingly shaped outer contour for shape-locking connection to the friction ring.
