Claims10
Locking device with a locking element for selective locking of at least a first selector shaft (4, 5, 6, 7) actuated by a shift finger (2a) and also a second selector shaft (4, 5, 6, 7), wherein the shift finger (2a) pivoted around a tilt axis (9a, 34) alternatively moveable to positively engage in one of the selector shafts (4, 5, 6, 7), and wherein the selector shaft (4, 5, 6, 7) in which the shift finger (2a) engages, is longitudinally displaceable in at least one direction by means of the shift finger (2a) pivoting around the pivot axis (8a, 36), and wherein the first selector shaft (4, 5, 6, 7) is longitudinally fixed by the locking member with respect to the second selector shaft (4, 5, 6, 7) when the shift finger (2a) pivoted around the tilt axis (9a, 34) positively engages in the second selector shaft (4, 5, 6, 7), wherein the locking member is a locking finger (12), the locking finger (12) alternatively positively engages in a slot (4b), open in a direction of the tilt axis (9a, 34) and also in the pivoting directions of the locking finger (12) pivoted around the tilt axis (9a, 34), on one of the selector shafts (4, 5, 6, 7), and wherein the first selector shaft (4, 5, 6, 7) is longitudinally fixed, when the shift finger (2a) pivoted around the tilt axis (9a, 34) positively engaging in the second selector shaft (4, 5, 6, 7);
- wherein the second selector shaft (4, 5, 6, 7) is longitudinally fixed by means of the locking finger (12) when the shift finger (2a) pivoted around the tilt axis (9a, 34) positively engages in the first selector shaft (4, 5, 6, 7);
- and wherein the locking finger (12) pivoting around the tilt axis (9a, 34) is pivotable in slots (4b) lying one behind another in a pivoting direction of the locking finger (12) and mutually aligned, until the shift finger (2a) positively engages in one of the selected longitudinally movable selector shafts (4, 5, 6, 7) and also the locking finger (12) positively engages in the slot (4b) of at least one selector shaft (4, 5, 6, 7) to be fixed.
Locking device according to claim 2, wherein at least three of the selector shafts (4, 5, 6, 7) are allocated to the shift finger (2a);
- wherein the locking finger (12) positively engages simultaneously in two of the selector shafts (4, 5, 6, 7) and the shift finger (2a) positively engages in one of the selector shafts (4, 5, 6, 7) movable longitudinally by means of the shift finger (2a);
- and wherein the locking finger (12) has a clearance space (12a) that interrupts the locking finger (12) in the pivoting direction of the locking finger (12) and located, upon fixing two selector shafts (4, 5, 6, 7) which are directly adjacent to the longitudinally freely movable selector shaft (4, 5, 6, 7), directly over the slot (4b) of the longitudinally freely movable selector shaft (4, 5, 6, 7);
- and wherein the selector shaft (4, 5, 6, 7) freely movable with the shift finger (2a) passes through the locking finger (12) at the clearance space (12a) without contact with the locking finger (12).
