Abstract:
Gear-shift device for a change-speed gearbox, comprising a shift actuator arranged rotatably and axially displaceably with respect to a central axis of a housing,a selection actuator coaxial with respect to the central axis and arranged rotatably relative to the housing, an actuator coaxial with respect to the central axis and arranged to be displaced exclusively axially relative to the housing, means for fixing the selection actuator with regard to the housing in longitudinal directions of the central axis, an engageable and disengageable brake for fixing the selection actuator with regard to the housing in the circumferential directions of the central axis, an auxiliary transmission for converting a reciprocating motion into a rotary motion, when two of the three actuators are arranged to be fixed in terms of movement with respect to one another, at least in the longitudinal directions of the central axis, and are connected to the third actuator by the auxiliary transmission, and an engageable and disengageable locking device is connected in terms of action both to the selection actuator and to the brake in such a manner that the selection actuator is fixable with regard to the housing alternately either exclusively in the circumferential directions or exclusively in the longitudinal directions of the central axis, the selection actuator is connected by the auxiliary transmission to the actuator which is arranged to be displaced exclusively axially with regard to the housing, a guide pin is guided in a fixed shift guide plate which represents a shift pattern of a manual shift lever, the guide pin being arranged in a manner fixed in terms of movement with regard to the shift actuator and radially to the central axis.
