  • the spring clips 104a, 104b are received in tongue grooves 110a, 110b of the first driving carriage 70 and the second driving carriage 80, cf. Fig. 10b , In the actuator 19 according to the Fig. 4a to 7
  • elastic elements of this kind can be received in a similar manner on the driving slides 70, 80, as well as on the slide guide 82.
  • the components such as the diagonal groove 76, the longitudinal groove 75, the drivers 84a, 84b, and the cam 78 are as shown in FIG Fig. 5 correspond, modified implemented.
  • the actuating element part 96b is pivotable about the longitudinal axis 16 together with the actuating element part 96a, but is excluded from displacement along the longitudinal axis 16 by suitable guides (not shown in more detail) on the housing side.
  • the diagonal groove 76 is disposed in the actuator part 96b, see FIG Fig. 10b . 11b and 12b .
  • a driver 114 is received, in contrast to the driver 84 according to Fig. 5 not fixed to the housing.
  • the driver 114 is disposed on a boom 112 of the second driving carriage 80.
  • the rotation of the actuating element part 96a causes no displacement of the first driving carriage 70, since the driver 68 is movable in the circumferential groove 66, cf. Fig. 12a ,
  • the longitudinal displacement of the Actuator element 96a is transmitted via the driver 68 on the circumferential groove 66 of the first driving carriage 70, see Fig. 12a ,
  • the embodiment pursued in the case of the actuating device 19a can also be used, for example, according to the power transmission device 30 Fig. 2 be easily switched in four different transmission configurations.
  • the operating logic can be used in conjunction with the Fig. 8a and 8b used.
