Disclosed herein is gear actuator for dual clutch transmission, including: a driving motor having a driving shaft formed with gear part, a pair of first and second gears gear-coupled to the gear part, first and second guide cams respectively connected to the first and second gears to rotate, a first power transfer unit transferring or cutting off the power from the driving motor to the first guide cam according to rotating direction of the first gear, a second power transfer unit transferring or cutting off the power from the driving motor to the second guide cam according to rotating direction of the second gear, a first finger shaft linearly moved by rotation of the first guide cam and performing a selection operation of an odd-numbered stage, and a second finger shaft linearly moved by rotation of the second guide cam and performing a selection operation of an even-numbered stage.

Gear actuator for dual clutch transmission

Disclosed herein is a shift device of a dual clutch transmission capable of simplifying a configuration of a shift control mechanism of the transmission and contributing to saving costs by sharing odd-stage and even-stage select mechanisms and individually including an odd-stage shift mechanism and an even-stage shift mechanism. The shift device of a dual clutch transmission includes: a select guide block () moving in a straight direction by a driving of the select motor (); a pair of control shafts () and () each shaft moving in a select direction by the straight movement of the select guide block; and a pair of odd-stage and even-stage shift motors () and () each providing a shaft rotating force to the pair of control shafts () and () in a shift direction.
