Abstract:
1. A drive device configured on a side such that the drive device can be connected to a drive, and which has a flexible element that is configured substantially in the shape of a wedge, having at least two flexible sections extending away from the drive and that are at a distance to each other on the side of the drive, the distance from each other of which is reduced in the direction away from the drive and which are coupled in the region of the end of the flexible element facing away from the drive in a power transmitting manner, wherein the flexible sections on the side of the drive are kept movable relative to each other substantially along the longitudinal axis of the wedge and that the flexible element is configured on the side of the drive such that it may be transferred to a different curvature pointing in the direction of the thickness of a flexible impact blade as a function of the relative position of the flexible sections.
