Composite brake disc

摘要

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.

1. A composite brake disk for a motor vehicle, comprising:
a brake disk chamber; and at least one associated brake ring joined to the brake disk chamber by a joining process, wherein, in a joint area, an inside brake ring tooth profile engages with a brake disk chamber tooth profile at an angle offset relative to a planar surface of the at least one associated brake ring, wherein brake disk chamber tooth faces of the brake disk chamber-tooth profile and brake ring tooth faces of the inside brake ring tooth profile have different fits in the joint area, wherein the brake disk chamber has a conical basic form before the joining process and a reference teething diameter, which increases towards an open end of the brake disk chamber, and wherein the conical basic form of the brake disk chamber is modified by the joining process.
