Abstract

A composite brake disk for a motor vehicle includes a brake disk chamber and a related brake ring connected together by a joining process. In one joint area an internal brake ring tooth profile engages in a brake disk chamber tooth profile. The brake disk chamber tooth profile has brake disk chamber tooth faces in circular arc form, whereas the brake ring-tooth profile has brake ring tooth faces in the form of an involute. Due to the special version of the pairing of two different tooth formats a fixed, load-bearing connection can be achieved between the brake disk chamber and the brake ring.
