Problems solved by technology

[0009] However, a vehicle with a conventional DCT cannot achieve a smooth start and may roll back due to slippage of the friction clutch when the vehicle is started on an uphill slope
Because the shift time needs to be shortened, the thermal capacity of the clutch according to the conventional DCT may cause shift shock

Abstract

A double clutch transmission includes a variable connector including a first clutch and a second clutch and outputting engine torque through the first and second clutches. An input driver includes a first input shaft connected to the engine with a plurality of input gears disposed on an exterior circumference thereof. A second input shaft is connected to the engine with a plurality of input gears disposed on an exterior circumference thereof. A speed output driver includes a first output shaft disposed in parallel with the input shafts, a first speed output disposed on the first output shaft with first and second synchronizers, a second output shaft disposed in parallel with the first and second input shafts, and a second speed output disposed on the second output shaft with third and fourth synchronizers. A reverse speed / motor driver is disposed between the input device and the speed output device.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0143099 filed on December 10, 2012 with the Korean Intellectual Property Office, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to dual clutch transmissions. More specifically, the present disclosure relates to a dual clutch that achieves smooth starting and shifting through an additionally installed electric motor / generator, improves fuel economy through regenerative braking, and improves vehicle performance by receiving torque from the electric motor during acceleration. acceleration performance.
