Abstract
A shifting device for a motor vehicle transmission is provided comprising a selector lever for selecting different shift positions (P, R, N, D, 3, 2, . . . ). The lever is mounted in a housing pivotably around at least one axis. A first locking member and at least one additional locking member are provided as angle levers, each arranged on the housing pivotably around a respective pivot axis. The locking members block the movement of the selector lever in different shift positions. An adjusting member is provided. A locking element provided at the selector lever is engaged by one of the locking members in the shift positions of the selector lever which are to be locked as a function of preset parameters.
Claims22
A shifting device for a motor vehicle transmission, the shifting device comprising:
- a housing;
- a selector lever for selecting different shift positions, said selector lever being mounted in said housing pivotably around at least one axis;
- a first locking member comprising an angle lever arranged on said housing pivotably around a first locking member pivot axis;
- an additional locking member comprising an additional angle lever arranged on said housing pivotably around an additional locking member pivot axis, said first locking member and said additional locking member blocking the movement of the selector lever in different shift positions;
- an adjusting member;
- and
- a locking element connected with said selector lever for movement together and pivoting movement of said locking element with said selector lever, said locking element being engaged by one of said first locking member and said additional locking member in the shift positions of the selector lever which are to be locked, locking said locking element and said selector lever as a function of preset parameters.
