Abstract

A transmission includes: first and second input shafts receiving power from an engine; an output shaft arranged in parallel with the first input shaft; first and second countershafts arranged in parallel with the first and second input shafts, respectively; a first shift unit making desired gear shifts between the first input shaft and the output shaft, and between the first input shaft and the first countershaft; a second shift unit arranged between the second input shaft and the second countershaft in order to perform of duplicate gear shifts; a power connection unit transmitting power from the first countershaft to the output shaft; and a one-way clutch transmitting power from the engine to the power connection unit through the second shift unit. In particular, each duplicate gear shift has a gear ratio substantially identical to at least one gear ratio of the gear shifts of the first shift unit.

Description

technical field [0001] The present invention relates to a transmission for a vehicle, and more particularly, the present invention relates to a structure of a transmission capable of automatic shifting. Background technique [0002] The statements in this section merely provide background information related to the present invention and may not constitute related art. [0003] In the prior art, an AMT (Automatic Manual Transmission) includes a clutch actuator for connecting / disconnecting the clutch and a shift actuator for engaging and disengaging gears. A desired gear is shifted, and the AMT can automatically shift gears by operating a clutch actuator and a shift actuator according to the driving conditions of the vehicle. [0004] However, with the AMT, in order to disengage the previous gear and engage the new desired gear by operating the shift actuator, it is necessary to cut off torque from the clutch actuator to the AMT. Such a torque cut causes a torque interruptio...
