Abstract
A sintered clutch ring () is described, comprising a rim of clutch teeth () which comprise wedge-like face surfaces () intersecting in an axial plane and flanks () sloping downwardly under an angle of inclination from the tooth back () against the tooth root, with the flanks () being relieved starting from a re-entrant, axially normal shoulder (). In order to provide advantageous conditions for press forming the flank reliefs it is proposed that the planes of intersection between the wedge-like face surfaces () extend outside of the center of the teeth and that the mutually axially offset shoulders () of the two flanks () of the clutch teeth () separate the relieved flanks () from a paraxial flank portion () which is substantially triangular and is adjacent to the face surfaces ().
