Abstract
A pull-type friction clutch having an annular part that is axially clamped to a disk spring and is axially fixedly connectable to an actuation sleeve of an actuation system. The annular part has axially raised lugs on its face bearing against the disk spring, and the lugs engage in slots that are provided between the disk spring tongues where the tongues are appropriately widened, to provide a form locking connection in the peripheral direction. As a result of the peripherally fixed attachment of the annular part to the disk spring, wear caused by a relative twist between the annular part and the disk spring is prevented.
