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.

Shifting device for a motor vehicle transmission, comprising:
- a said selector lever (1) for selecting different shift positions (P, R, N, D, 3, 2, . . . ), which is mounted in a said housing (3) pivotably around at least one said axis (2),
- a said first locking member (4) and at least one said additional locking member (5), which block the movement of the said selector lever (1) in different shift positions,
- a said adjusting member (6), as well as
- a said locking element (7), which is present at the said selector lever (1) and which is engaged by one of the said locking members (4, 5) in the shift positions of the selector lever which are to be locked, as a function of preset parameters,
- characterized in that
- the said locking members (4, 5) are angle levers arranged on the said housing (3) pivotably around a said pivot axis (8, 9) each.
Shifting device in accordance with one of the above claims,
- characterized in that
- the said adjusting member (6) is coupled with the said locking members (4, 5).
Shifting device in accordance with one of the above claims,
- characterized in that
- on their side facing the said locking element (7), the said locking members (4, 5) have a said elevated engaging contour (10), which can be engaged with a said, approximately complementary recess (11) of the said locking element (7).
Shifting device in accordance with one of the above claims,
- characterized in that
- the said locking element (7) has said sliding surfaces (12, 13) to facilitate the engaging and disengaging movements of the said locking members (4, 5).
Shifting device in accordance with one of the above claims,
- characterized that
- the said selector lever (1) has a said strap-shaped section (17), on the outer contour of which at least one said locking element (7) is fastened at least on one side.
Shifting device in accordance with one of the above claims,
- characterized in that
- the said locking elements (4, 5) are identical components.
Shifting device in accordance with one of the above claims,
- characterized in that
- the said adjusting member (6) is an electromagnet with a said armature (6.3), which can be extended from its said housing (6.1) on both sides in the axial direction and is pretensioned by means of a said spring (6.2).
Shifting device in accordance with one of the above claims,
- characterize in that
- the shifting device as a whole has a modular design in the manner of a modular system.
