Abstract

A constant velocity fixed joint for large articulation angles and a high torque capacity has an inner member and an outer member produced with undercut-free opposing first outer running grooves and first inner running grooves as well as opposing outer running grooves and second inner running grooves starting from different open end faces. To achieve a constant track depth, as possible, via the articulation angle, the webs between two circumferentially adjoining outer running grooves are divided into first and second inner faces which extend, in an undercut-free way, from the same open end face of the directly adjoining outer running grooves.
