Abstract
An actuating device for a motor vehicle transmission having multiple transmission steps, having a threaded spindle which is mounted so it is rotationally movable and axially fixed and a spindle nut which is positioned on this threaded spindle and may be driven thereby, and also having a first component, which is positioned so it is axially fixed and rotatable to select gears of the motor vehicle transmission, which may be coupled and/or is coupled via a rotational carrier unit to the spindle nut, so that the first component may be driven to rotate by the threaded spindle via the spindle nut to select gears, a braking unit being provided to reduce and/or avoid axial position changes of the spindle nut caused by mass inertia as a result a braking procedures of the threaded spindle from a movement rotationally driving the first component; as well as a motor vehicle transmission unit, a motor vehicle drivetrain, and a method for reducing or avoiding control errors caused by mass inertia in the control of gear changing actions in a motor vehicle transmission.
