- a switching drum 2 as described above
- the two roller elements 70a, 70b as also described above.
- only one roller element 70a, 70b will be described, but its construction also applies to the other roller elements 70a, 70b.
- the roller element 70a, 70b has in its guide track 3/4, which is designed as a circumferential groove, a referencing element 40 in the form of a ramp / recess 40, which is introduced into the otherwise substantially nikrundformige guideway 3/4 and thus the diameter the guideway 3/4 reduced in a certain scope.
- the referencing element 40 is thus an integral part of the roller element 70a, 70b.
- the referencing element for example, as a cam, whose diameter then would in turn increase the guideway 3, 4 locally.
- the referencing element 40 cooperates with a signal indication device 45.
- the signal indication device 45 is configured as the pin / pin / switching pin 26 of the engaging in the respective guideway 3/4 portion of the shift fork 12, 13.
- the pin 26 thus forms an engagement element / contact element 10, 1 1, which engages in the guideway 3, 4 and is slidably mounted in this.
- the signal indication device 45 acts in this way with the referencing element 40 in such a way that a position signal can be generated during a relative displacement of the signal indication device 45 and the referencing element 40, for example during a rotation of the roller element 70a, 70b in a specific rotational position of the roller element 70a, 70b.
- the referencing element 40 cooperates with the signal indication device 45 in the specific rotational position in such a way that the position signal is generated by a mechanical resistance which changes the drive force of the drive motor. That is, when the pin 26 drops at the edge 50 in the particular rotational position, upon further rotation, this causes a momentary torque variation on the roller member 70b and thus on the drive motor, since the pin 26 by means of the previously described spring 27 against the roller member 70b in the guideway 4 is pressed. The pin 26 acts on the roller element 70b with a certain frictional force. When the edge 50 is exceeded, this frictional force is briefly reduced and thus the torque changed abruptly.
- the ramp 40 is chosen in its slope so that it does not come to a self-locking between the pin 26 and the ramp 40, that is, a blocking of the roller element 70a, 70b.
- the ramp 40 is even selected in such a way that the characteristic of the ramp 40 characteristic curve of the torque fluctuation generates a specific position signal, which also not shown here of a clarity, with the drive motor electrically connected control unit is compared with a reference signal to allow a conclusion about the position of the pin 26 in the guide track 4 at the specific rotational position.
- FIG. 7 thus shows the construction of a roller element 2 / a shift drum 2 with referencing 40 in the form of ramps 40 in grooves, or guideways 3 and 4.
- the pins 26 of the shift forks 12 and 13 engage in the guideways 4.3 and are subjected to force by the ramps 40.
- the spring 27 By the application of force, the spring 27 (see Fig. 3) is compressed.
- the compression can then be converted by a signal generation system / control unit into a signal, e.g. be converted in the form of a change in resistance. This can then be determined by comparison with a stored lookup table (LUT) which has stored corresponding reference signals, the exact circumferential position of the shift drum, or the roller elements 2 can be determined.
- LUT stored lookup table
- the position signal may be a voltage signal, resistance signal or current signal.
- the reference signal is a signal pattern consisting of at least two distinguishable sub-signals.
- the ramp 40 which forms the referencing element 40 is also at the same time preferably that actuation region into which a clutch actuation means for actuating the at least one clutch can be inserted.
- the referencing element 40 does not have to be an integral part of the roller element 70a, 70b, but can also be arranged to be rotatable and in turn offset in the axial direction on a separate, substantially disk-shaped referencing element 55.
- the referencing element 40 is configured as a recess and allows it to tap in a specific rotational position, a position signal on the drive motor.
- a bolt-like pin / pin 26 here comprises the signal indicating means 45 a spring-biased ball 60 which is biased against the outer peripheral surface of the Referenz istsorgans 55 and, as can be seen in Fig. 8, when passing through the circular recess 40 along the ramp 40th slides along and thus in turn briefly changes the necessary torque of the drive motor, which in turn the position signal is generated.
