Abstract:
The invention relates to a gear and gate (XY) actuator device for a gearbox, comprising a main gear axis that extends parallel to the direction of the rotational axis of the selectable shafts, the direction thereof being subsequently referred to as the X direction. A desired gear is engaged using a shift finger (10) that can be displaced in the X direction along said main gear axis. The gearbox comprises at least two linear shift guides (20, 22, 24) which extend in the X direction parallel to the main gear axis and with which said shift finger (10) can engage, in order to select a specific linear shift guide, a shift rod (12) which can be translationally displaced in the direction of the main gear axis, the shift finger (10) being mounted on said shift rod (12) for conjoined axial and/or rotational movement such that a desired gear can be engaged by displacing the shift finger (10) and a linear shift guide is selected by rotating the shift finger (10) in relation to said linear shift guides (20, 22, 24).
