Abstract
A shift device for a transmission, which comprises a sliding sleeve, a shift fork engaging in the sliding sleeve, and an actuator that can rotate on a shaft that is disposed at an angle to the transmission shaft. In order to provide a simple and reliable control that satisfies all functional requirements, a cam having two flanks and a flattened section on the maximum radius is disposed on the shaft. On the base of the shift fork, two interacting pushrods are disposed at a fixed distance so that one pushrod rests against the one flank and the other pushrod rests against the other flank and one pushrod rests against the flattened section in at least one extreme position.
