Abstract

A positioning device for an output component for automatically shifting gears of a motor vehicle transmission that undergoes two types of movements comprises a plurality of drives. The movement of each drive can be transmitted via a transmission mechanism to the output component. A first drive causes the output component to undergo movement of a first type, and a second drive causes the output component to undergo movement of a second type. The first drive is connected to a sliding element. The sliding element is axially fixed, but movable in the circumferential direction relative to the output component. The second drive is rotatably fixed, but axially movable output component.
