Abstract:
1. An actuator device for a motor vehicle transmission, in which the transmission comprises: at least two shafts; a plurality of gear sets for the achievement of different gear steps; and a plurality of shift mechanisms, each of which may be actuated to produce or release a rotationally fixed shaft-gear connection, the plurality of shift mechanisms including first and second shift rails or first and second shift forks; in which the actuator device comprises: a main actuator device rotatable about a first axis and displaceable parallel to the first axis and having at least one shift finger that is movable about the first axis and parallel to the first axis to engage the first or second shift rail for the engagement of gears, wherein the main actuator device includes a first surface; and, a secondary actuator device rotatable about a second axis, different than the first axis, and having at least one disengagement finger, wherein each said disengagement finger is movable about the second axis to engage the first or second shift rail or to engage the first or second shift fork for the disengagement of gears, wherein the secondary actuator device includes a second surface; wherein the main actuator device and the secondary actuator device cooperate to produce controlled relative movements of one of the at least one shift finger and one of the at least one disengagement finger; with a first shift finger from the at least one shift finger.
