Patent ID: 8590411

Claim:
An automated manual transmission comprising: a first input shaft to which power of an engine is transmitted; a second input shaft to which the power of the engine is transmitted; a drive gear part installed at the first input shaft and the second input shaft, the drive gear part including a first drive gear installed at the first input shaft and configured to transmit the power; a second drive gear installed at the first input shaft and configured to transmit the power; a third drive gear installed at the second input shaft and configured to transmit the power; and a fourth drive gear installed at the second input shaft and configured to transmit the power, wherein the first drive gear, the second drive gear, the third drive gear and the fourth drive gear are meshed with the driven gear part to constitute four gear arrays; a clutch part configured to transmit or interrupt the power of the engine to the first input shaft or the second input shaft; a first output shaft to which the power is transmitted from the first input shaft or the second input shaft; a second output shaft, to which the power is transmitted from the first input shaft or the second input shaft, including a plurality of shafts disposed on the same axis; a driven gear part constituted by a plurality of driven gears installed at the first output shaft and the second output shaft, the driven gear part including a first driven gear rotatably connected to the second output shaft and meshed with the first drive gear; a second driven gear rotatably connected to the first output shaft and meshed with the first drive gear; a third driven gear rotatably connected to the first output shaft and meshed with the second drive gear; a fourth driven gear rotatably connected to the first output shaft and meshed with the third drive gear; a fifth driven gear connected to the second output shaft and meshed with the third drive gear; and a synchronization part configured to connect or disconnect the first output shaft or the second output shaft and the driven gear part to realize multi-stage gear shift steps, wherein the clutch part comprises: a first clutch installed at the first input shaft and configured to transmit or interrupt the power of the engine; and a second clutch installed at the second input shaft and configured to transmit or interrupt the power of the engine.
