Abstract
An actuator for gutter selection in a gear positioning device for an automatic manual transmission has a selector shaft with a selector finger. A gutter selection device is movable back and forth along an axis into a first position and a second position. The selector finger of the selector shaft can move into engagement and out of engagement with the gutter selection device. A single valve device is provided for determining the first and second positions of the gutter selection device.
Claims16
An actuator for gutter selection in a gear positioning device for an automatic manual transmission, the actuator comprising:
- a selector shaft (3) with a selector finger (4);
- a gutter selection device (2) movable back and forth along an axis (X—X) into a first position and a second position;
- wherein the selector finger (4) of the selector shaft (3) is configured to be moved into engagement and out of engagement with the gutter selection device (2);
- and
- a single valve device (20), wherein the first and second positions of the gutter selection device (2) are determined by the single valve device (20).
A method for gutter selection in a gear positioning device for an automatic manual transmission, the method comprising the steps:
- positioning a gutter selection device (2), movable back and forth along an axis (X—X), in a first position depending on a 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 a movement of the gutter selection device (2) from the first position into the second position is effected by precisely one valve device (20).
