Presented is a drive device with a piezo-stack actuator (12) and a hub translation that converts the expansion length of Piezostapelaktors in an enlarged setting stroke of an actuator. The actuator is acted upon by a spring element (23) in an actuating position and is non-positively coupled with a transmission element, which in turn is acted upon by a further spring element into a rest position and at the same time frictionally coupled to the output end of the Piezostapelaktors. The transmission element forces in the rest position the actuator counter him acting spring element into a rest position and releases it in a caused by the piezo-stack actuator stroke position, so that the actuator assumes the operating position under the action of him acting spring element.
