Selector lever reset device for a vehicle gearbox, and method and device for operating such a selector lever reset device
The present disclosure provides a selector lever resetting device for a vehicle transmission. The selector lever resetting device may include a selector lever configured to select a gear position of the vehicle transmission and a lever guide device, the lever guide device having a first sliding element and a locking slide. The first sliding element may be adjustable along a first sliding axis and has a latching contour. The selector lever may be coupled to the first sliding element and configured to be moved along the sliding axis between a latching position and an operating position. The locking slide may be adjustable along a second sliding axis to move at least between a latching position and a release position.

where the locking slide includes a locking element, the locking element being engaged with the latching contour when the selector lever is in the operating position and the locking slide is in the locking position, and the locking element being released from the latching contour when the locking slide is in the release position, and
where the locking slide includes a block element that is separate from the locking element, the block element extending in a direction parallel to the first sliding axis along a top surface of the locking slide, wherein the block element is positioned to prevent movement of the selector lever along the first sliding axis when the locking slide is in a blocking position; and
a gear shifting gate with a first recess associated with the operating position and a second recess associated with the latching position,
wherein the first recess has a depth greater than the second recess, and
wherein the first recess and the second recess are connected by an inclined exchange lane.
2. The selector lever resetting device of claim 1 , further comprising a spring element configured to press the locking element against the latching contour.
3. The selector lever resetting device of claim 1 , further comprising a drive unit configured to move the locking slide between the locking position and the release position.
4. The selector lever resetting device of claim 3 , further comprising a gearbox coupled to the drive unit, where the gearbox is configured to transmit a rotary motion generated by the drive unit into a linear movement of the locking slide.
5. The selector lever resetting device of claim 1 , where a lever end of the select lever can be switched between the first recess and the second recess, and further comprising a preload device configured to apply a preload force to the lever end of the selector lever to move the selector lever.
6. The selector lever resetting device of claim 5 , wherein the preload device includes a spring such that the lever end to have a tendency to move from the second recess, through the inclined exchange lane, and to the first recess absent an external force.
7. The selector lever resetting device of claim 5 , where the selector lever includes a lever recess, where a latching body of the preload device is located within the lever recess, and where the preload force applied to the lever end of the selector lever is greater when the selector lever is in the first recess than when the selector lever is in the second recess.
8. The selector lever resetting device of claim 1 , where the first recess is an automatic gate for automatic switching of the vehicle transmission and the second recess is a manual gate for manual switching of the vehicle transmission.
9. The selector lever resetting device of claim 1 , where the blocking element prevents a locking body from entering the second recess when the locking slide is in the blocking position.
10. The selector lever resetting device of claim 1 , where the selector lever is received by a recess of the first sliding element.
11. The selector lever resetting device of claim 1 , further comprising a second sliding element perpendicularly movable with respect to the first sliding element, where the second sliding element is movable along a third sliding axis parallel to the second slide axis, and wherein the second sliding element is configured to allow movement of the select lever between a plurality of predefined lever positions.
12. A selector lever resetting device for a vehicle transmission, the selector lever resetting device comprising:
a selector lever configured to select a gear position of the vehicle transmission;
a lever guide device having a first sliding element and a locking slide,
where the first sliding element is adjustable along a first sliding axis and has a latching contour,
where the selector lever is coupled to the first sliding element and is movable along the first sliding axis between a first position and a second position,
where the locking slide is adjustable along a second sliding axis to move at least between a locking position and a release position,
where the locking slide includes a locking element, the locking element configured to engage with the latching contour when the locking slide is in the locking position and when the first sliding element is in at least one of the first position and the second position,
where the locking slide includes a block element that is separate from the locking element, the block element extending in a direction parallel to the first sliding axis along a top surface of the locking slide, wherein the block element is positioned to prevent movement of the selector lever along the first sliding axis when the locking slide is in a blocking position, and
where the first sliding axis is perpendicular to the second sliding axis; and
a gear shifting gate with a first recess associated with the first position and a second recess associated with the second position,
wherein the first recess has a depth greater than the second recess, and
wherein the first recess and the second recess are connected by an inclined exchange lane.
13. The selector lever resetting device of claim 12 , further comprising a spring element configured to press the locking element against the latching contour.
14. The selector lever resetting device of claim 12 , further comprising a drive unit configured to move the locking slide between the locking position and the release position.
15. The selector lever resetting device of claim 14 , further comprising a gearbox coupled to the drive unit, where the gearbox is configured to transmit a rotary motion generated by the drive unit into a linear movement of the locking slide.
16. The selector lever resetting device of claim 12 , where a lever end of the select lever can be switched between the first recess and the second recess, and further comprising a preload device configured to apply a preload force to the lever end of the selector lever such that the lever end of the selector lever has a tendency to move towards the first recess.
