ABSTRACT:
A single motor transmission shifting mechanism with exactly one electric motor for generating drive motions for selecting, and for generating drive motions for shifting gears of a motor vehicle transmission device, and with a threaded spindle for switching from a mode, in which selection motions can be effectuated, into a mode, in which shifting motions can be effectuated, and with a shifting shaft, which can be moved in axial direction for selecting, and which can be rotated around its longitudinal axis for shifting, wherein all components, transferring the drive load for shifting from the electric motor to the shifting shaft during shifting operation, maintain their axial position relative to the longitudinal axis of the threaded spindle during this shifting operation.
