ABSTRACT:
A gearbox actuator comprising a selector shaft2which is arranged in a housing and is driven by a drive. A shift finger3and disengaging shaped elements4used to actuate gearshift rails are arranged on the selector shaft, and jibs for12-15supporting and guiding the gearshift rails are arranged on the housing. The gearbox actuator1comprises the central selector shaft2mounted in bearing elements19and comprises a shift finger3and two disengaging shaped elements4arranged in the center thereof, at a distance corresponding to the width of a channel. Preferably, the selector shaft2is driven by a brushless motor5by means of a double planetary stage6and a toothed segment7which engages a toothed wheel16that is preferably positioned in a housing element17. A preferably second brushless motor8drives a sliding element37by means of spindle9, the sliding element displacing the shift finger3and the disengaging shaped elements4on the selector shaft2.
