Abstract:
1. A gear actuator for a motor vehicle transmission design ( 3 ), that has several ratio steps for forming gears, whereby the gear actuator ( 1 ) comprises a gear-shift shaft ( 58 , 66 ) that is operatively arranged so the gear-shift shaft can move in rotation for the shifting of gears and can move axially for the selection of gears, and a shift gate ( 2 ), wherein the shift gate ( 2 ) includes a fixedly mounted first shift gate part ( 10 ), a second shift gate part ( 12 ) that is coupled to the gear-shift shaft so the second shift gate part can move axially and in rotation with respect to an axis of the gear-shift shaft, and wherein the first shift gate part ( 10 ) has several recesses ( 14 , 16 , 18 , 20 , 22 ), wherein the recesses are spaced from each other in an axial direction substantially parallel to an axis of the gear shift shaft, into each of which recesses the second shift gate part ( 12 ) can rotate, depending on an axial position of the second shift gate part, wherein the axially spaced recesses ( 14 , 16 , 18 , 20 , 22 ) of the first shift gate parts ( 10 ) are assigned to different shift tracks of the gear actuators ( 1 ) and that in the positions of the gear actuator ( 1 ), in which it is positioned outside of a shift track, the first ( 10 ) and the second shift gate part ( 12 ) connect with positive engagement to block a movement capability of the second shift gate part ( 12 ).
