Abstract
The present invention relates to a gutter selection actuator as well as a method for gutter selection in a transmission. The gutter selection actuator has precisely one double-action gutter piston (2) and one valve device (20) and can be controlled by a common control pressure. A selector finger (4) of a selector shaft (3) can be engaged and disengaged with the gutter piston (2). The position and the movement of the gutter piston (2) is determined in this connection exclusively by the valve device (20).

Actuator for gutter selection in a gear positioning device for an automatic manual transmission, comprising a selector shaft (3) with a selector finger (4) and a gutter selection device (2) which is movable back and forth along an axis (X-X) in order to assume a first position and a second position, wherein the selector finger (4) of the selector shaft (3) can be moved into engagement and out of engagement with the gutter selection device (2) and wherein the position of the gutter selection device (2) can be determined by means of precisely one valve device (20).
Method for gutter selection in a gear positioning device for an automatic manual transmission, comprising the steps:
- positioning the gutter selection device (2), movable back and forth along an axis (X-X), in a first position depending on the desired next gutter selection,
- connecting a selector shaft (3) with the gutter selection device (2),
- moving the gutter selection device (2) with the selector shaft (3) into a second position so that the selector shaft (3) is positioned in a neighboring gutter, and
- disengaging the selector shaft (3) from the gutter selection device (2) in order to shift a gear,
- wherein the movement of the gutter selection device (2) from the first position into the second position is carried out by means of precisely one valve device (20).
