Abstract
A mechanism for actuating a shifting element. A first shifting element half of a brake is axially fixedly connected to a drive machine output shaft, which, when rotational movement of the output shaft equals the disengaging movement of the shifting element, is rotationally fixed to the output shaft. In the event of an engaging force, opposite the disengaging movement of the shifting element, an axial force acts on the output shaft, such that the first shifting element half frictionally engages with an axially and rotationally fixed second shifting element half. In the event of a disengaging force that acts in the disengaging direction of the shifting element, an axial force acts on the motor output shaft such that the first shifting element half of the brake is moved out of frictional engagement with the second shifting element half.
