By rotating an individual element it is held in such a way that the two camshafts can therefore be used to tension the associated pressure-pressure plates independently of one another by means of a plate independently of the other plates, using their clamping elements by means of cams and loosen them. The disadvantage here, however, is that they can be clamped and released, characterized by the fact that the presence of several camshafts is characterized by the fact that the cams (23) have a structural complexity and space requirement,
