Abstract
A selector drum for an automated manual transmission, in particular a dual clutch transmission, having a selector drum body, which can be mounted in the manual transmission for rotation about an axis of rotation, wherein at least one shifting contour is formed on the selector drum body, said shifting contour extending over a peripheral portion of the selector drum body, wherein the selector drum is designed for shifting at least one high gear stage, one middle gear stage and one low gear stage, wherein the at least one shifting contour has a shifting contour switch in a region of a switch gear portion.

A selector drum for a dual clutch transmission, the selector drum having a selector drum body, which can be mounted in the transmission for rotation about an axis of rotation, wherein at least one shifting contour is formed on the selector drum body, said shifting contour extending over a peripheral portion of the selector drum body, wherein the selector drum is designed for shifting at least one high gear stage, one middle gear stage and one low gear stage, wherein the at least one shifting contour has a shifting contour switch in a region of a switch gear portion,
- wherein the switch gear portion is assigned to the middle gear stage, wherein the switch gear portion is designed, by means of the shifting contour switch, in such a way that the middle gear stage is shifted in a first direction of rotation of the selector drum body and is not shifted in a second direction of rotation, wherein the at least one shifting contour is also designed in such a way that, in the second direction of rotation of the selector drum body, the high gear stage can remain shifted if a driver assigned to the middle gear stage is in a region of the switch gear portion, such that, proceeding from the high gear stage, the low gear stage can be shifted without shifting the middle gear stage;
- wherein the at least one shifting contour has an individual shifting contour, in which a first driver and a second driver engage, wherein the first driver is assigned to the high gear stage and wherein the second driver is assigned to the middle gear stage.
A selector drum for a dual clutch transmission, the selector drum comprising:
- a selector drum body configured to be mounted in the dual clutch transmission for rotation about an axis of rotation;
- at least one shifting contour formed on the selector drum body, the shifting contour extending over a peripheral portion of the selector drum body;
- the selector drum configured to provide shifting between at least one high gear stage, one middle gear stage and one low gear stage;
- the at least one shifting contour having a shifting contour switch in a region of a switch gear portion;
- the switch gear portion assigned to the middle gear stage;
- the switch gear portion configured such that, by means of the shifting contour switch, the middle gear stage is shifted in a first direction of rotation of the selector drum body and is not shifted in a second direction of rotation;
- wherein the at least one shifting contour is also configured such that, in the second direction of rotation of the selector drum body, the high gear stage can remain shifted if a driver assigned to the middle gear stage is in a region of the switch gear portion, such that, proceeding from the high gear stage, the low gear stage can be shifted without shifting the middle gear stage;
- wherein the at least one shifting contour has an individual shifting contour, in which a first driver and a second driver engage, wherein the first driver is assigned to the high gear stage and wherein the second driver is assigned to the middle gear stage.
