Abstract

A gear shifting apparatus for a multi-speed transmission for an electric vehicle includes a shifting unit controlling gear shifting by a torque of an actuator, and a parking unit controlling a parking state by the torque of the actuator. In particular, the actuator includes a control motor transmitting a driving torque to a first driven gear and a second driven gear through a drive gear externally gear-meshed with the driven gears, and the shifting unit includes: a shift fork slidably mounted on a fork rail and activating the gear shifting; a profile drum connected to the first driven gear externally engaged with the drive gear, and having a profile groove formed along an exterior circumference of the profile drum; and a shift lug integrally formed with the shift fork and coupled with the profile groove.
