Transmission device for a motor vehicle

A transmission device for a motor vehicle, comprising:

• a plurality of gear sets forming gear ratio steps;
• a plurality of connecting elements (10), including shift rails or shift forks, mounted in an axially movable manner;
• a respective shift mouthpiece (12) for each connecting element in the plurality of connecting elements, wherein each respective shift mouthpiece includes first functional regions (42, 42a) for a movement in a first direction and second functional regions (34, 34a) for a movement in a second direction, opposite the first direction, wherein the first functional regions (42, 42a) and the second functional regions (34, 34a) are axially symmetrical;
• and,
• an actuation device (18) for actuating the plurality of connecting elements (10), the actuation device including;
• a control shaft (20) mounted in a rotatable manner or in a swiveling and axially movable manner for actuating the plurality of connecting elements (10);
• at least one shift finger (26) for acting on at least one connecting element (10) from the plurality of connecting elements (10) for the engagement of gear ratio steps;
• and,
• at least one secondary control element (28) for acting on the at least one connecting element (10) for the disengagement and/or locking of gear ratio steps, wherein:
• each of the at least one secondary control element includes third functional regions (40, 40a) for a movement in the first direction and fourth functional regions (32, 32a) for a movement in the second direction:
• the third functional regions (40, 40a) and the fourth functional regions (32, 32a) are axially symmetrical;
• in a neutral position the at least one secondary control element (28) extends perpendicular to a direction of movement or axial direction (16) of the at least one connecting element (10);
• and,
• for the respective shift mouthpiece (12) and the at least one secondary control element (28), all of the functional regions comprise curved surfaces.
