A shifting device for a multi-shaft sliding gear arrangement having a plurality of sliding gear blocks displaceable in an axial direction, each one of which is connected, by way of a mechanical transmission device, to a separate electric servo-drive. Each servo-drive comprises an electric servo-motor equipped with a gear reduction unit and a planar cam drive which is arranged between the servo-motor and the transmission device and has a pivotal output lever. The output lever is connected to a sliding gear block at an end remote from the pivotal support therefor. The two end positions of movement of the output lever correspond to the end positions of the sliding gear block. |
