BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive device for a dual clutch transmission, and more particularly, to a drive device for a dual clutch transmission that implements an automatic transmission based on a manual transmission operation.

In general, an Automated Manual Transmission (AMT) is a transmission configured to have a simple structure of a manual transmission including an external gear set and a mechanical clutch, and a convenient operating structure and shift algorithm of the automatic transmission while maintaining economical fuel economy.

The automatic manual transmission is configured to automatically operate the clutch and shift lever according to the engine speed and shift timing in the structure of the manual transmission. For example, a drive system of an automatic manual transmission implements shifting in a transmission by a shift operation and a select operation.

For example, a dual clutch transmission (DCT) has advantages of low power loss, easy operation, and high shift time. For example, when the vehicle travels in the first stage which is the hall means, the two stages of the pair means are in a state of being able to be shifted.

When shifting in such a state, the first stage as the hole means is shut off, and the two stages as the even means are connected. Due to this characteristic, the dual clutch transmission shortens the shifting time and makes the shifting time shorter than the general manual transmission.

The driving apparatus for operating the conventional dual clutch transmission has the hole means solenoid and the even means solenoid for the select operation of the odd-numbered stage and the even-numbered means, respectively. During gear shifting, the Hall means solenoids and even solenoid solenoids generate noise, complicate the structure of the drive system, and increase assembly costs and manufacturing costs.

The shift mechanism unit 2 and the select mechanism unit 3 are mechanical structures that can move and rotate the control shaft 1 in the axial direction to perform a shift operation and a select operation.

That is, the control shaft 1 is moved in the axial direction in accordance with the select operation of the select mechanism section 3, and the control finger 11 provided on the control shaft 1 is provided with a plurality of shift lugs (Not shown).

The control shaft 1 is rotated in accordance with the shift operation of the shift mechanism unit 2 so that the control finger 11 provided on the control shaft 1 moves the selected shift lug in the axial direction, Speed shift.

For example, the control shaft 1 includes an even-numbered control shaft 12 and an even-numbered control shaft 13. The control finger 11 includes an even-numbered control finger 121 and an odd-numbered control finger 131.

The pair of select plates
A rotary oil tool formed on the inner side to induce rotation of the one-pair select gear, and
And a coupling groove which is formed concavely outward in the rotational oil tool to be coupled to the pair of select gears and which maintains twice the angular interval,
And a drive unit for driving the dual clutch transmission.
