ABSTRACT:
A drive arrangement for an axle (4) for the actuation of an actuating element (3) comprises a first drive unit (1) coupled to the axle (4) and a second drive unit (2) coupled to the axle (4). A lever (21) mounted pivotably on a holding system (24, 26) in a pivot point (20) engages the first drive unit (1) on the one hand and the second drive unit (2) on the other hand. Thanks to the lever (21), the two drive units (1, 2) can be twisted within certain limits relative to each other around the axle (4) to compensate for position errors.
