A gear-shift device for a change-speed gearbox, includes a shift actuator, a selection actuator, an actuator which is arranged such that it can be displaced exclusively axially with regard to a housing, an auxiliary transmission for converting a rotary motion into a reciprocating motion, a brake which is connected to the selection actuator and an engageable and disengageable locking device. These components are arranged in terms of their action in such a manner that two of the three actuators are arranged fixed in terms of movement with respect to one another and are connected to the third actuator by the auxiliary transmission. The selection actuator is fixed either in a rotationally fixed or axially undisplaceable manner with regard to the housing. A fixed slotted shift guide can be provided singly or together with a slotted change-interlock guide for the shift actuator, with the guide plate being used as a brake and locking device.

Control device for a variable speed gear

An arrangement actuates the shift mechanism of a change-speed gearbox and engages and disengages a main clutch via a common servomotor. The shift mechanism, with the interposition of an auxiliary clutch which can be engaged and disengaged by a servomotor, can be actuated independently of the main clutch.
