Definitions
- the invention relates to an actuating device, in particular for actuating at least one motor vehicle component, in particular a transmission and / or a clutch.
- the invention further relates to a method for actuating at least one motor vehicle component, in particular a transmission and / or a clutch, with such an actuating device.
- the speed ratios between a transmission input shaft and a transmission output shaft are formed by pairs of gears.
- embodiments are known, for example, as a spur gear.
- the shift of the transmission takes place here by a switching mechanism in the transmission.
- This switching mechanism is connected to a manually connected transmission via a linkage or a cable with a shift lever.
- the actuation of the switching mechanism by means of an actuator, which comprises an actuator for selecting the translation stage and an actuator for the insertion or the interpretation of the translation stage.
- a torque is usually transmitted from a drive motor of the vehicle via a clutch to the transmission input shaft.
- gears of the individual gear ratios are usually mounted on the transmission input shaft.
- the transmission output shaft is arranged parallel to the transmission input shaft and also has gears for the respective gear ratio.
- the gears of both waves form pairs and interlock.
- These gears are fixedly mounted on the two shafts, depending on the design, or freely rotating, but axially fixed.
- they are fixed with a dog clutch on the shaft.
- a dog clutch is radially fixed on the shaft and can be moved axially.
- a translation stage To insert a translation stage, you must first select a translation stage to be inserted.
- the translation stage ie for the switching operation, provided for the selected gear stage jaw clutch is pressed by the shift fork against a gear. If the tooth profiles engage, the gear is engaged.
- the gear pairs are arranged in pairs, so that the shift fork in one direction actuates a first gear stage and inserts in the opposite direction of actuation, a second gear stage. If a plurality of such pairs of gear pairs are provided, these can be actuated, for example, by means of shift rods, wherein the selection of the shift rod requires a first actuation process and the movement of the shift rod in a selected direction requires a second actuation process.
- this construction typically results in a H-shift scheme in which a shift lever in a selector gate can be moved between shift lanes to select, in which step the shift rail is selected. A shift of the gear ratio is then effected by moving the shift lever in the selected shift gate, in which case the shift rod is actuated.
- a first actuator which selects, for example via a selector finger to be operated shift rod, wherein a second actuator is provided to rotate the selector finger in one or the other direction to insert the previously selected gear ratio.
- the circuit of a transmission therefore requires an actuator with two

- the actuating device 1; 21; 41 includes a transmission 3 with shift rails or gear rails 5, shift fingers 6 and Auslegehebeln 7.
- the transmission 3 is actuated via a gear actuator 10.
- the transmission actuator 10 comprises an actuating shaft 12 which is rotatable on the one hand and axially displaceable on the other hand. By the axial displacement of the actuating shaft 12, a selection movement in the transmission 3 can be represented. By rotating the actuating shaft 12, a switching movement in the transmission 3 can be represented.
- the selection movement in the transmission 3 is initiated by an electric actuator 14.

- the pump actuator 19 is connected via a hydraulic line 24 to a cylinder with a hydraulic piston 22.
