Abstract
A gear shifting apparatus for a multi-speed transmission 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 of the shifting unit and a second driven gear of the parking unit through a drive gear externally gear-meshed with the driven gears, and the shifting unit includes: a fork slider slidably mounted on a fork rail, a shift fork integrally formed with the fork slider, a cam block connected to the first driven gear engaged with the drive gear and having a cam surface on an exterior circumference for shift-stages, a cam contact pin integrally formed with the fork slider and contacting the cam surface, and a return spring mounted around the fork rail.
