- a rotatably mounted shift drum 7 is provided, which is arranged axially parallel to the central transmission axis of rotation 6.
- the shift drum 7 is assigned to an oil sump 24 of the bottom bracket gear for better oil supply. Due to the fact that the shift drum 7 is at least partially immersed in the oil located in the oil sump 24, the shift drum 7 and the surrounding components are supplied with oil, which is indicated in particular in FIG.
- an electromechanical shift actuator 8 is arranged inside the shift drum 7, which is designed at least in sections as a hollow shaft. Accordingly, a radially nested design of shift drum 7 and electromechanical shift actuator 8 is provided.

- the rotation angle sensor 20 arranged on the transmission housing side is preferably fastened to a thin wall of the housing cover 19 on the outside.
- the housing cover 19 is preferably made of aluminum or plastic, so that the encoder signal can be detected directly by the rotation angle sensor 20 arranged in the dry area through the non-ferromagnetic wall.
- the electric servomotor of the switching actuator 8 is preferably a BLDC motor with Hall sensors. Control is via a 3-stage cascade PI controller.

- a plurality of shift gates 25 are provided on the outer circumference of the shift drum 7 .
- the shifting gates 25 are designed differently over the circumference with regard to their elevations and depressions or mountains and valleys.
- Each shift gate 25 of the shift drum 7 is associated with a brake pawl 5 for actuating this or for shifting to a predetermined gear ratio.

- This second deep groove ball bearing 22 is connected via its inner ring to the Shift drum 7 frictionally connected via the press fit and guided axially via its outer ring between the transmission housing 12 and the support sleeve 11. This results in a particularly short tolerance chain in the radial direction and at the same time in the axial direction at the air gap between the rotary encoder 18 on the shift drum 7 and the rotary encoder 20 on the housing cover 19, which increases the precision of the shifting process.
