Patent ID: 7698965

Claim:
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 , 42 a ) for a movement in a first direction and second functional regions ( 34 , 34 a ) for a movement in a second direction, opposite the first direction, wherein the first functional regions ( 42 , 42 a ) and the second functional regions ( 34 , 34 a ) 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 , 40 a ) for a movement in the first direction and fourth functional regions ( 32 , 32 a ) for a movement in the second direction: the third functional regions ( 40 , 40 a ) and the fourth functional regions ( 32 , 32 a ) 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.
