Patent ID: 8201469

Claim:
A transmission for a vehicle, said transmission comprising: a first input shaft connected to a first clutch and a second input shaft connected to a second clutch, said first clutch and said second clutch being connected to an engine, respectively; an intermediate shaft arranged in parallel with said first input shaft and said second input shaft; an output shaft which outputs a power from said transmission; a plurality of gear trains for constituting transmission gear ratios provided between said first input shaft and said intermediate shaft, and also between said second input shaft and said intermediate shaft, the gear trains being provided on said first input shaft and on said second input shaft constituting every other transmission gear ratios; an output shaft reduction gear train provided between said intermediate shaft and said output shaft, said output shaft reduction gear train being disposed at an end of said intermediate shaft and transmitting a power from said intermediate shaft to said output shaft at a reduced rotational speed; a direct connection clutch provided between said second input shaft and said output shaft; and an intermediate shaft connection clutch provided on said output shaft reduction gear train, wherein said direct connection clutch is connected and said intermediate shaft connection clutch is disconnected when a power of said engine is transmitted directly to said output shaft at a same rotational speed as said engine, such that said intermediate shaft stops rotating when the power of said engine is transmitted directly to said output shaft, and wherein said direct connection clutch is connected and said intermediate shaft connection clutch is disconnected for constituting one of said transmission gear ratios in which said output shaft rotates at a speed exceeding said engine, such that the power of said engine is transmitted to said output shaft through said first input shaft, said intermediate shaft rotating at a lower speed than said output shaft, and said second input shaft.
