  • actuating means for the displacement and rotation of a switching shaft are necessary, which generally comprise two levers.
  • the one lever of this arrangement usually the selector lever is pivoted to move the shift shaft axially.
  • a selection movement is transmitted to the selector lever in a linear movement of the shift shaft.
  • the other lever usually the shift lever, rotates the shift shaft e.g. for switching and engaging the gears.
  • the (shift) lever and the (selector) lever are connected via linkage, cables and the like kinematically connected to a manual shift lever or servomotors o.
  • Such actuators are known, for example, from DE 197 54 760 A1, from DE 101 11 911 A1, from DE 101 38 729 A1 and from EP 0 933 563 A1.
  • the coupling of the selector lever with the switching shaft is relatively expensive to manufacture, since a pivoting movement must be transmitted in a linear adjusting movement.
  • this engagement for coupling the two parts is usually made of sheet metal or integrated in a balance weight of a manufactured by casting component.
  • An object of the present invention is seen to provide a simple and inexpensive to manufacture mechanical coupling between a selector lever and a selector shaft of a transmission, which allows precise transmission of a pivoting movement of the selector lever in a linear displacement of the shift shaft.
  • the present invention comprises an actuating device for a change gearbox of a motor vehicle with at least two levers coupled to one another, which interact with a switching shaft for their axial and radial movement.
  • a selector lever is coupled to a transmission device for the axial displacement of the shift shaft.
  • a shift lever is rotatably connected to the radial rotation of the shift shaft with this.
  • the transmission device has at least one engagement element fixed axially on the control shaft, which interacts with a coupling element which is arranged at a free end of the pivotably mounted selector lever.

  • the engagement element may have the shape of a roller, which is firmly connected to the shift shaft. Possibly. a rotation of the roller on the shift shaft can be allowed to reduce, for example, the adjustment forces.
  • These webs or the roller can in particular be made of plastic, in which case preferably wear-resistant and low-friction materials such as polyamide (PA) or polytetrafluoroethylene (PTFE) come into question, since these can provide the desired durability.
